(Supporting Documents)

These documents are available both as printed manuals and as electronic documents. The most up-to-date Cisco IOS documentation can be found on the latest Documentation CD-ROM and on the Web. The electronic documents contain updates and modifications made after the paper documents were printed.

You can access the electronic documents either on the Cisco Documentation CD-ROM or at Cisco Connection Online (CCO) on the World Wide Web.

On the CD-ROM, go to the Cisco  IOS Software Configuration database, select Cisco  IOS Release  11.1, and follow the link to the Cisco  IOS Configuration Guides and Command References.

CCO is on the World Wide Web at http://www.cisco.com, http://www-europe.cisco.com, or http://www-china.cisco.com. From CCO, go to the Technical Documentation page to find the Cisco  IOS Software Configuration database. Then, select Cisco  IOS Release  11.1, and follow the link to the Cisco  IOS Configuration Guides and Command References.

Additional information about CCO and the Documentation CD-ROM is in the sections "Cisco Connection Online" and "Documentation CD-ROM" at the end of these release notes.

Platform Support

You can run all Cisco  IOS 11.1 releases on these Cisco hardware platforms, except as noted:

For each of the supported platforms, Release  11.1 enables your Cisco device to use certain LAN and WAN interfaces and data rates.

For a list of interfaces supported by Release  11.1 for each platform, see Table 1, Table 2, Table 3, and Table 4 (following).

For each platform, you can use any of the interfaces or data rates labeled "Yes" in the table. Release  11.1 does not support interfaces or data rates that are labeled "No."

Cisco  IOS Packaging

The Cisco  IOS software is packaged into "feature sets" (also called "software images"). There are many different feature sets available, and each feature set contains a specific subset of Cisco  IOS features. Not all feature sets are available with all platforms. Also, some feature sets support different features when run on different platforms.

To learn what features are available with each feature set, see tables Table 5 through Table 14 (following). These tables summarize what features you can use when running a specific feature set on a specific platform. A "Yes" in the table indicates that the feature is available in the feature set.

You can use these tables to determine if you can configure and use a specific feature with your platform and Release  11.1 feature set.

Note For some platforms, you can purchase a "feature pack," which contains a group of one or more feature sets on a CD-ROM. For more information about feature packs, refer to the release notes for Cisco  IOS Release  11.1  feature packs, or refer to the Feature Pack Information web page on CCO or the Documentation CD-ROM in the Cisco  IOS Release  11.1 documentation area.

Memory Requirements

Beginning with Cisco  IOS Release  10.3, some software image (feature set) sizes exceed 4  MB and, when compressed, exceed 2  MB. Also, some systems now require more than 1 MB of main system memory for data structure tables.

For Cisco routers to take advantage of the Release  11.1 features, you need to have the code or main system memory as listed in Table 15. If you do not, you must upgrade your memory. Some platforms have specific chip or architecture requirements that affect what can be upgraded and in what increments.

The memory requirements listed in Table 15 are minimum requirements. Your specific hardware configuration and the software features you chose to deploy could require you to have more memory.

Note For the Cisco  7000 and Cisco  7010 routers to recognize Flash memory cards, 11.0 boot ROMs (or later) are required.

1If you need to upgrade the main memory for your Cisco  1003, Cisco  1004, or Cisco  1005 router, be sure to order the upgrade specific to your router.
2For Cisco  2509 through Cisco 2512 access servers, and the Cisco 2522 and Cisco 2523 routers, 4 MB DRAM is the minimum recommended.
3The OSPF LANFRAD feature set is available in Release  11.1(9) and later.
4Memory requirements listed are per card. Each AS5100 supports up to three cards, so that the maximum memory needed for any AS5100 is three times the listed number.
5The Cisco  4500 requires 16 MB DRAM when two NP-CT1 or two NP-CE1 Network Processor Modules are installed in the chassis.
6Except the Cisco  7000 with RSP7000. For a Cisco  7000 with an RSP7000 card, refer to the memory requirements for Cisco  75xx platforms.
7To use the HSA feature, 32 MB DRAM is the minimum recommended memory (per RSP).
8To use the HSA feature, 24 MB DRAM is the minimum recommended memory (per RSP).

New Features in Release  11.1(6) and Later 11.1 Releases

There are no new software features or platform support added in Release  11.1(6) or in any later Cisco  IOS 11.1 release. Release  11.1(5) was the last maintenance release to add new features or platform support.

New Features in Release  11.1(5)

This section describes the software enhancements that were added to Release  11.1(5).

Support for Second-Generation Channel Interface (CIP2)

The CIP2 is the follow-on product to the original CIP, and provides increases in performance, capacity, reliability, and serviceability.

The CIP2 includes the following improvements over the original CIP:

The CIP2 operates with the CxBus in the Cisco  7000 series routers with either of the following processor types:

The CIP2 operates with the CyBus in the Cisco 7500 series routers, which use the Route Switch Processor (RSP).

CIP microcode is required if you will be using the CIP2. See the "Important Notes" section for more information about CIP microcode.

Support for Cisco 7200 Series Platforms

The Cisco  7200 series is a series of multiprotocol routers that delivers the high-performance, high port density, and availability features typically associated with high-end systems. The Cisco  7200 series supports Cisco's Inter-Switch Link (ISL) Protocol for transporting virtual LANs (VLANs) across Fast Ethernet. VLANs enable the logical definition of bridge groups that can be overlaid on the physical network.

The Cisco  7206 router can be configured with up to 48 Ethernet ports, 24 Token Ring ports, 24 serial ports, 7 Fast Ethernet ports, and 6 FDDI ports.

Four feature sets are available in Cisco  IOS Release  11.1(5) to support the Cisco  7200 series:

Refer to Table 6 for a list of features included in each of these sets.

Support for the Cisco AS5200

The Cisco  AS5200 Universal Access Server provides mixed asynchronous and ISDN line service to accommodate both mobile users and telecommuters with one server. This line of access servers contains channel service units (CSUs), channel banks, communication servers, switches, routers, and 48 modems in one standalone chassis that accommodates up to 48 users dialing-in simultaneously.

The following feature sets are available for the Cisco  AS5200. Refer to Table 10 for a complete list of the features provided in these sets.

Cisco Web Browser Interface

A Web browser interface is available on any Cisco product running Cisco  IOS Release  11.1(5) software, or later. This Web interface allows you to log in to a router or access server and process Cisco  IOS software commands. It operates much like the command line interface (CLI) on a terminal. To process commands using the Web interface, click on the "Monitor the Router" link from the router's home page. All Cisco products running Cisco  IOS Release  11.0(10) or 11.1(5) software or later have a home page.

ClickStart Enhancements

ClickStart, which allows you to use a standard Web browser to configure and monitor a Cisco router, has been enhanced. You can now use it to configure a Cisco  1005 router that has one Ethernet and either one Frame Relay or one asynchronous serial interface. For additional information about ClickStart, see the "New Features in Release 11.1(2)" section.

DLSw+ Enhancements

In Release  11.1(5), DLSw+ can be used as a "virtual" data-link control for other SNA features in the Cisco  IOS software, including:

LNM over DLSw+ allows DLSw+ to be used in Token Ring networks that are managed by IBM's LNM software. Using this feature, LNM can be used to manage Token Ring LANs, control access units, and Token Ring attached devices over a DLSw+ network. All management functions continue to operate as they would in a source-route bridged network or an RSRB network.
DSPU over DLSw+ allows Cisco's DSPU feature to operate in conjunction with DLSw+ in the same router. DLSw+ can be used either upstream (toward the mainframe) or downstream (away from the mainframe) of DSPU. DSPU concentration consolidates the appearance of multiple physical units (PUs) into a single PU appearance to VTAM, minimizing memory and cycles in central site resources (VTAM, NCP, and routers) and speeding network startup.
SNA service point over DLSw+ allows Cisco's SNA service point feature to be used in conjunction with DLSw+ in the same router. Using this feature, SNA service point can be configured in remote routers, and DLSw+ can provide the path for the remote service point PU to communicate with NetView. This allows full management visibility of resources from a NetView 390 console, while concurrently offering the value-added features of DLSw+ in an SNA network.

Support for Fast Ethernet---100E NIM for Cisco  4500 and Cisco  4700

Support for the Fast Ethernet network interface module (NIM) is added in Release  11.1(5). The Cisco  4500 series (Cisco 4500, Cisco 4500-M, Cisco 4700, and Cisco 4700-M) routers support a Fast Ethernet network interface module (NIM) with a PCI bus interface to its DEC21140 controller chip. The Fast Ethernet NIM for Cisco 4500 and Cisco 4700 provides a single full-duplex, 100-Mbps Ethernet interface.

MIP Flow Control

Custom queuing and priority queuing are now available for the MultiChannel Interface Processor (MIP) in RSP systems (Cisco  7500 series and Cisco 7000 series with RSP7000).

NetFlow Switching

NetFlow Switching brings the benefits of connection-oriented switching to network layer devices. With NetFlow Switching, routers become network switches able to combine quality-of-service and security capabilities with high performance. Coupled with the large bandwidth capacity of Cisco's 7500 series, NetFlow Switching allows customers to provide many of the capabilities associated with ATM on their existing routed infrastructure.

NetFlow Switching operates at the network and transport layers so it can incorporate user and application oriented information to make switching decisions such as allowing access and providing specific quality of service. NetFlow Switching achieves high performance by operating on connection-like flows between source/destination IP addresses. Cisco LAN Switches such as the Catalyst 5000, will be able to take advantage of NetFlow Switching with the incorporation of support for multilayer switching and Cisco  IOS software.

Optimum Switching

Optimum Switching is quite similar to fast switching from a high level. The optimum switching cache is a separate cache using a more efficient data structure than the fast-switching cache to achieve better performance. In addition, the data caching at the processor is optimized to boost performance further. Optimum Switching requires the architecture of the Cisco 7500 series Route Switch Processor (RSP).

Support for the Packet OC-3 Interface

Support for the Packet OC-3 interface on the Packet over SONET Interface Processor (POSIP) is added in Release  11.1(5). The POSIP for Cisco 7500 series and Cisco RSP/7000 routers provides a single 155.520-Mbps, OC-3 physical layer interface for packet-based traffic. This OC-3 interface is fully compatible with SONET and Synchronous Digital Hierarchy (SDH) network facilities and is compliant with RFC 1619, "PPP over SONET/SDH," and RFC 1662, "PPP in HDLC-like Framing."

To support this interface, Packet over SONET Interface Processor microcode is also added to this release.

New Features in Release  11.1(4)

This section describes the software enhancements that were added to Release  11.1(4).

New Feature Sets for Cisco  1005

Cisco  IOS Release  11.1(4) supports two new Cisco  1005 feature sets:

Refer to Table 14 for a list of features included in each of these sets.

High System Availability (HSA)

HSA is an advanced software feature of the Cisco  7500 series architecture. HSA increases the availability and uptime of the Cisco  7507 and Cisco  7513 routers. This increase is accomplished through a master/slave relationship between two RSPs. If the slave RSP detects an error condition, it automatically takes control and reboots the system without user intervention. This automatic action minimizes network interruption and increases system availability.

Note HSA requires a ROM Monitor upgrade. See the "Important Notes" section for more information.

HSA can be used in the following situations:

HSA is only supported in feature set images that include a "v" in the name, such as the RSP subset image rsp-jv-mz.111-4.

See the "Important Notes" section for more information.

New Features in Release  11.1(3)

This section describes the software enhancements that were added to Release  11.1(3).

Channel Service Unit/Data Service Unit (CSU/DSU) Management Information Base (MIB)

This Cisco-proprietary MIB for integrated CSU/DSU is available in Release  11.1(3) and later. This MIB is available for use with the Cisco  2524 and Cisco  2525 products, and is for T1 and switched 56-kbps interfaces. It enables network managers to retrieve line statistics and CSU/DSU configuration data.

Support for the Cisco  2524 and Cisco  2525 Platforms

The Cisco 2524 and Cisco 2525 routers eliminate the need for a separate terminal adapter on an ISDN line, or separate channel service unit/data service units (CSU/DSUs) on synchronous serial WAN interfaces.

These platforms support a removable BRI or BRI with integrated NT1 interface, a LAN interface (either Ethernet or Token Ring), and two WAN interface slots.

New commands have been added to the Cisco  IOS software to support the Cisco  2524 and Cisco  2525.

The Cisco  2524 and Cisco  2525 support RFC 1406, Definitions of Managed Objects for the DS1 and E1 Interface Types.

Cisco  IOS Release  11.0(5) also supports the Cisco  2524 and Cisco  2525 routers.

Note The Cisco  2524 and Cisco  2525 require a minimum 11.0(5)-level boot ROM.

Support for the Cisco  2520, Cisco  2521, Cisco  2522, and Cisco  2523 Platforms

The Cisco  2520 through Cisco  2523 models merge router and communication server features to serve access and telecommuting requirements in a single platform. WAN aggregation, telecommuting, branch office, and IBM protocol applications are well-suited to these Cisco devices.

The interfaces available in each model are shown below.

Cisco  2520

1 Ethernet, 2 high-speed synchronous serial, 2  low-speed synchronous/asynchronous serial, 1  ISDN BRI

Cisco  2521

1 Token Ring, 2 high-speed synchronous serial, 2  low-speed synchronous/asynchronous serial, 1  ISDN BRI

Cisco  2522

1 Ethernet, 2 high-speed synchronous serial, 8  low-speed synchronous/asynchronous serial, 1  ISDN BRI

Cisco  2523

1 Token Ring, 2 high-speed synchronous serial, 8  low-speed synchronous/asynchronous serial, 1  ISDN BRI

The low-speed serial interfaces (maximum speed 115.2 kbps) are capable of supporting both synchronous and asynchronous protocols.

LAN Frame Relay Access Device (FRAD) Feature Set

The LAN FRAD feature set is supported on the Cisco  2501, Cisco  2502, Cisco  2520, Cisco  2521, Cisco  2522, and Cisco  2523 routers.

IP/Open Shortest Path First (OSPF)/Protocol Independent Multicast (PIM) Feature Set

This feature set for the Cisco  1005 router contains the functionality of the IP feature set, but includes support for OSPF and PIM.

New Features in Release  11.1(2)

This section describes the software enhancements that were added to Release  11.1(2).

New Configuration Tool---ClickStart

ClickStart allows you to use a standard Web browser, such as Netscape or Mosaic, to configure and monitor a Cisco router. You can use ClickStart to configure a Cisco  1003 or Cisco  1004 router that has one Ethernet and one ISDN Basic Rate Interface (BRI). You configure the router to dial your Internet service provider, and your Internet service provider supplies an ISDN connection to the Internet. You can also use ClickStart to monitor any Cisco router that is running Cisco  IOS Release  11.1(2), Release  11.0(6), or later.

If you have a Cisco  1003 or Cisco  1004 router, you can automatically use ClickStart to monitor your router.

If you have any other Cisco router, you must enable ClickStart before you can use it to monitor your router. To do this, follow this procedure:

Step 1 To enable ClickStart, use the ip http server global configuration command.

Step 2 By default, ClickStart uses port 80 to communicate with the router. If you want to configure a different port, use the ip http port number global configuration command. The number argument is the number of the port you want to use for ClickStart.

Virtual LAN (VLAN) Routing

Release  11.1(2) supports IP and IPX routing and transparent 802.1d bridging between Inter-Switch Link (ISL)-encapsulated VLANs on Cisco  7000 and Cisco  7500 series routers with RSPs. This functionality is also supported on the Cisco  7000 with Route Processors (RPs) and Switch Processors (SPs) and/or Silicon Switch Processors (SSPs), with limited performance.

VLAN allows you to logically segment end-user ports into autonomous virtual workgroups. Logical segmentation provides benefits in address administration, security, and management of network broadcast activity across the enterprise. To communicate between VLANs, a routing function is required (or bridging, in the case of nonroutable protocol types). Cisco  IOS software offers two alternatives for communication between VLANs: dedicated VLAN ports and VLAN subinterfaces.

Note that the only IPX encapsulation supported in ISL is 802.3.

Security access lists for controlling the type of access within or outside of a VLAN can be configured using subinterfaces within Cisco routers. This control provides an additional layer of security when VLANs are interconnected.

VLAN routing

New Features in Release  11.1(1)

This section describes new features and enhancements available in the initial Cisco  IOS Release  11.1 of the router products software.

Platform Support

This section describes new platforms and interfaces supported by the initial release of Cisco  IOS Release  11.1.

Cisco  1005

The Cisco 1005 synchronous serial router connects small, remote Ethernet LANs to WANs over leased lines, Frame Relay, Switched Multimegabit Data Service (SMDS), Switched-56, and X.25. The Cisco  1005 is already supported on Releases  11.0(4), 10.3(6), and higher.

AAL3/4 E3/DS3 for Cisco  4500 and Cisco  4700 ATM NIM

Asynchronous Transfer Mode (ATM) is supported on the Cisco  4500 and Cisco  4700 routers, using the Cisco ATM Network Interface Module (NIM) cards. The ATM adaptation layer 3/4 (AAL3/4), and additional NIM variants for use with E3/DS3 services are supported in Release  11.1. (Support is also available in Cisco  IOS Release  11.0(5).) ATM on the Cisco 4500 and Cisco 4700 routers is configured differently from that on the Cisco  7000 routers. Refer to the Wide-Area Networking Configuration Guide for configuration information.

Backbone Protocol Routing Features

This section describes the backbone protocol routing features that are new in the initial release of Cisco  IOS Release  11.1.

TCP/IP Features

The following features have been added to the Cisco  IOS TCP/IP software:

NHRP has been enhanced to support IPX in addition to the IP support introduced in Cisco  IOS Release  10.3. With NHRP, you can dynamically resolve IPX addresses in large-scale WAN environments in addition to resolving IP addresses. NHRP will operate using ATM, SMDS, or GRE tunneling.
Fast Install ensures that the floating static route is installed as soon as either the routing protocol or interface reports a connectivity loss. This enables faster convergence when using dial-on-demand circuits to back up, for example, a leased-line or Frame Relay service.
Note MD5 authentication in RIPv2 is not supported in Release  11.1(1) or Release  11.1(2).
If you implement RIP you can now make more efficient use of allocated address space by implementing variable-length subnet masks (VLSM) within networks.
RIPv2 adds to the choices of classless routing protocols supported by Cisco  IOS software. This is the primary mechanism to improve scaling of the Internet routing system as a whole.
Note Care must be taken when combining RIPv2 routers and RIPv1-compatible hosts. Because it cannot apply the supplied subnet mask, a RIPv1 host may misinterpret route information.
In some multi-homed environments, hosts listen to RIPv1 broadcasts to enable them to switch their traffic to a new router, should the main router or connection fail. Cisco recommends the choice of alternative technologies such as RFC 792 ICMP Router Discovery Protocol, or Hot Standby Router Protocol (HSRP) as alternatives for hosts.

Desktop Protocols

This section describes the desktop protocol features that are new in the initial release of Cisco  IOS Release  11.1.

AppleTalk Features

The following features have been added to Cisco's AppleTalk software:

SMRP optimizes Apple Computer's Quicktime Conferencing (QTC) traffic flow of audio, video, and shared data over AppleTalk-based routed networks. QTC is a powerful multimedia application that enables multiple end stations to participate in multipoint, collaborative, multimedia operations. SMRP is the networking complement of QTC. SMRP optimizes communication among QTC end systems with reduced CPU utilization by eliminating the duplicate transmission of identical packets to multiple receivers. SMRP streamlines network throughput by eliminating duplicate and unnecessary traffic propagation. It dynamically establishes unique shortest-path distribution trees to restrict traffic propagation to only those parts of the network that contain receiving end stations. SMRP provides just-in-time packet duplication upon encountering a branch in the distribution tree.
Cisco routers have been SMRP-enabled since Cisco  IOS Release  11.0. New in this release is enhanced performance through fast switching on the Cisco  4000 and Cisco  7500 series routers.

ISO CLNS Features

The benefits for TARP include:

Novell Features

The following features have been added to Cisco's Novell software:

Enhanced IGRP to NLSP route redistribution provides unparalleled flexibility to users of large IPX networks. Previously, when IPX networks grew to the point where RIP and SAP were no longer able to adequately support them, users were forced to upgrade to either Enhanced IGRP or NLSP to gain the scalability benefits inherent to these protocols. Through the use of Enhanced IGRP to NLSP route redistribution, users may now select the routing protocol, or combination of routing protocols, that meets their needs. For example, an IPX network can now be built that uses a combination of RIP and NLSP on the NetWare servers and uses Enhanced IGRP as the single backbone protocol.
Note IPX Input Access Lists can be fast switched, but they cannot be enabled on a cBus-based router configured for autonomous or SSE switching.
Other implementations of load sharing rely on a round-robin algorithm that transmits successive packets over alternate, equal-cost paths without regard to the end host. Round-robin load sharing increases the likelihood of packets being received out of order at the destination host. Out-of-order packets must often be retransmitted in IPX environments, leading to much higher application delay and network congestion.
Because per-host load sharing sends all packets destined for an end host over the same media interface, the likelihood of packets being received out of order is greatly reduced and minimizes retransmissions and network overhead.
NLSP route aggregation provides several important benefits to users of large IPX networks:
It is recommended that large IPX networks (conservatively estimated as those containing over 400 network addresses according to Novell design guidelines) be split into smaller NLSP areas. Previously, NLSP was specified as a single-area routing protocol, meaning that individual NLSP areas had to use IPX RIP to communicate routing information. Cisco's new implementation of NLSP allows multiple instances of NLSP to run on the same router, and allows routing information to be redistributed between areas. This allows much larger NLSP networks to exist.
When possible, ranges of addresses within an area can be aggregated (or summarized) into a single route entry. Because the number of these entries in the routing databases is minimized and update traffic is reduced, aggregation results in a much more efficient routing process.
Note To derive the maximum benefit from NLSP route aggregation it is important that network addresses be assigned properly in IPX environments. Network addresses should be assigned in a structured, hierarchical manner. Additionally, since other IPX routing protocols cannot interpret summarized route entries, the use of NLSP route aggregation in a Cisco router that is also using IPX RIP or Enhanced IGRP must be carefully planned and implemented.
Without routing support for FDDI_RAW IPX encapsulation, packets of this format are recognized only by switches or bridges on the FDDI ring. Neither clients, servers, nor routers directly connected to the ring can recognize this type of packet. By implementing FDDI_RAW encapsulation, it is possible to recognize and route these packets, either to other LAN or WAN media, or back onto FDDI in one of the Novell-approved FDDI formats. Routing support for FDDI_RAW can eliminate the requirement of changing Ethernet encapsulation on servers and clients when deploying switched internetworks.
IPX header compression can reduce header information size from 30 bytes to as little as 1 byte. This can save bandwidth and reduce costs associated with IPX routing over WAN links. In addition, the use of CIPX is negotiated automatically on WAN links using the IPXWAN protocol, which reduces the complexity of implementing these circuits.

Wide-Area Networking Features

This section describes the wide-area networking features that are new in the initial release of Cisco  IOS Release  11.1.

ISDN/DDR Enhancements

The following feature has been added to Cisco's ISDN and DDR software:

SMDS

The following features have been added to Cisco's SMDS software:

Only IEEE 802.3, IEEE 802.5, and FDDI with or without frame check sequence (FCS) frames will be supported in the fast-switched and process-switched modes. Previously, only IEEE 802.3 frames were process-switched.

ATM Enhancements

The following features have been added to Cisco's Asynchronous Transfer Mode (ATM) software:

Core Enhancements

The following features have been added to the Cisco 7000 series and Cisco 7500 series routers:

The VIP-1FE is based on a single one-port Fast Ethernet port adapter. The VIP-1FE/1FE is based on two one-port Fast Ethernet port adapters. Both the VIP-1FE and VIP-1FE/1FE support IEEE  802.3u Fast Ethernet specifications for half- and full-duplex operation.
The VIP-1FE/4E is based on a one-port Fast Ethernet port adapter that supports distributed IP switching for the FEIP and a four-port (10BaseT) Ethernet port adapter. VIP distributed IP switching can switch to these output interfaces: VIP-FE/4E, VIP-FE, EIP, FIP, and FSIP, HIP, and MIP with HDLC encapsulations. (VIP distributed IP switching is not available in Release  11.1(1). It will be available in a future maintenance release of Cisco  IOS Release  11.1.)
Each Fast Ethernet port has an RJ-45 connector (100BaseTX, two-pair category 5 UTP), and an MII connector that provides connectivity to 100BaseFX and 100BaseT4 through customer-provided external transceivers. The Fast Ethernet port adapters can be configured for Inter-Switch Link (ISL), which supports VLANs between Catalyst 5000 high-performance switches and IEEE 802.1000 TB-VLAN for transparently bridging VLANs. (ISL is not supported in Release  11.1(1), but will be supported in Release  11.1(2) for RSP and RSP7000 processors with the FEIP and VIP cards.)
Because of its modular design, the VIP can be configured to support mixed media. Because this version of the VIP supports both Ethernet and Fast Ethernet, customers can now realize much better slot utilization in either the Cisco  7000 series or the Cisco  7500 series.
For full-duplex operation, the VIP-1FE is recommended.
The primary goal of distributed IP switching is to provide scalable switching performance for the Cisco  7500 series of high-end multiprotocol routers. With the introduction of distributed IP switching, Cisco  7500 switching performance scales as more VIPs are introduced into the system. VIP distributed IP switching can switch to these output interfaces: VIP-FE/4E, VIP-FE, EIP, FIP, and FSIP, HIP, and MIP with HDLC encapsulations.
VIP Distributed Switching requires the architecture of the Cisco  7500 series Route Switch Processor (RSP). VIP distributed IP flow switching is not available for VIPs installed in Cisco  7000 series platforms.
HSA is an advanced software feature of the Cisco  7500 series architecture. HSA increases the availability and uptime of the Cisco  7507 and Cisco  7513 routers. This increase is accomplished through a master/slave relationship between two RSPs. If the slave RSP detects an error condition it automatically takes control and reboots the system without user intervention. This automatic action minimizes network interruption and increases system availability.
HSA can be used in the following situations:
This feature became available in Cisco  IOS Release  11.1(4).
Note HSA requires a ROM Monitor upgrade. See the "Important Notes" section for more information.
The SMIP is a 2-port channelized interface processor that supports T1 and E1 interfaces and offers the same port configuration options as the MIP.
In conjunction with the Cisco  1000 series, the SSIP and SMIP provide the capability to cost-effectively network even the smallest branches. For Internet service providers, the SSIP, SMIP, and Cisco  1000 series significantly reduce the cost of adding customers, which allows Internet services to be profitably provided to a larger market.
The SSIP and SMIP do not currently support full Cisco  IOS software functionality. Please refer to Product Bulletin 397, which details the Cisco  IOS software functionality supported by the SSIP and SMIP.
Although these features are included in Cisco  IOS Software Release  11.1, the SSIP and SMIP are already supported in Release  10.3(6), Release  11.0(4), and later.
Note Cisco routers do not support SRB over FDDI when the router is an end station on an FDDI LAN.
The Flash MIB enables a user to use network management stations and CiscoWorks to manage and upgrade router software. With MIB support, this feature is now SNMP-manageable.
RSP7000 functionality is similar to a Cisco  7505 with RSP1, except that CyBus is not supported. CIP, FEIP, and VIP (CyBus interface processors) operate in CxBus mode.

Access and Communication Servers

In Cisco  IOS Release  11.1, the network manager can have a trap message sent when the source MAC address violation occurs. The SNMP trap message may be sent once, or at a decaying rate. The decaying rate option provides the first SNMP trap message immediately, the second trap at 2 minutes, the third trap at 4 minutes. This continues until 32 minutes have passed. The decaying trap messages can be terminated by the NMS by using the MIB variable TrapAcked.
Additional MIB variables are provided in the agent to allow the NMS to query the violation. MAC security MIB variables provide information such as last illegal source address, timestamp of the first violation, timestamp of the last violation, and number of violation frames.
Because SNMP uses UDP, a single trap notification might get lost. It is possible to configure the router to send multiple traps at a decaying rate. This ensures that the trap message will be received by the NMS.
LANE is also the underlying technology that supports virtual LANs (VLANs) over ATM networks. By providing the needed Layer 3 routing connection between Layer 2 VLANs, a Cisco  4500 or Cisco  4700 router with an NP-1A ATM network processor module and LANE technology provides standards-based routing between VLANs over ATM.
LANE requires Interim Local Management Interface (ILMI) and point-to-multipoint signaling capabilities on the switches on which it operates (VP tunneling is acceptable where signaling is not offered, such as a ATM WAN). The LANE services on the router ATM interfaces interoperate with Cisco LECs, including Cisco's ATM NICs and the Catalyst 5000. Cisco is pursuing interoperability with other third-party ATM LECs.

IBM Functionality Features

This section describes the IBM network software features and support that are new in the initial release of Cisco  IOS Release  11.1.

New Features

The following new IBM software features are available:

This feature simplifies network management by providing additional visibility of SNA network resources and by sending notifications about problems with PU and LU connectivity. When a downstream PU changes state, a DSPU is unable to activate a downstream PU, or a DSPU is unable to activate a downstream LU, it is mapped to an SNA message sent to a host operator, which generally appears in a NetView or NetMaster log. To minimize unnecessary noise across the network and in SNMP and NetView or NetMaster logs, there are four configurable notification levels (off, low, medium, and high).
Data link layer enhancements include:
APPN over PPP also allows APPN to be transported over an Integrated Switched Digital Network (ISDN).
Enhanced logging and debugging functions enable debug output that is more meaningful and useful, including better documentation of the error and debug output, more user control of the type and amount of debug output generated, and more descriptive information in the messages.
Because there is no standard way for transporting APPN over SMDS, a Cisco-proprietary method is used.
Note In some cases, APPN over SMDS may not interoperate with other vendors' SMDS implementations, because a proprietary method is being implemented.
BAN simplifies configuration in an environment where multiple remote SNA devices need to share a single PVC, and where there are no central site routers for SNA. It offers load balancing and provides the flexibility to build a redundant path to the Network Control Programs (NCPs).
Note BAN only applies to SNA devices on Ethernet or Token Ring. It does not apply to SDLC-attached devices. BAN requires NCP 7.3 at the central site. BNN and BAN can share the same DLCI to the NCP.

Data Link Switching+ (DLSw+) Features and Enhancements

The following features have been added to Cisco's DLSw+ software:

LNM support includes configuration report services, ring error monitor, and the ring parameter server. In addition, the DLSw+ router notifies LNM of certain events that might occur on a Token Ring, such as notification of a new station joining the Token Ring, or that the ring has entered failure mode known as beaconing.
This feature will be available in a future Cisco  IOS 11.1 software maintenance release.
These enhancements minimize WAN costs in switched environments. In addition, peer connections are only established when needed, maximizing scalability and minimizing cost.

Access and Communication Server Features

This section describes the access and communication server features that are new in the initial release of Cisco  IOS Release  11.1.

NBFCP:
With NBFCP:
With modem auto-configuring, no direct configuration of modems is required. All modems with a modem database entry are automatically recognized, and modems not found in the modem database can be defined clearly and quickly as the access server prompts for specific modem command strings.
Using the NCS server network, network managers can offer IPX dial-in and dial-out services on the same Cisco access server.
Note Because of Novell split-horizon rules it is necessary to disable all other NCS servers on the same network where the Cisco access server is deployed for NASI outbound connections.
This feature allows the identification of a username associated with a TCP connection.
The Identification Protocol support is not useful for securing access servers. It is a protocol for identifying the other end of a TCP connection. It does not authenticate or authorize the connection.
Cisco is implementing a two-phased approach to the implementation of Kerberos. Phase 1, delivered in Cisco  IOS Release  11.1, permits authentication on the router using Kerberos. (Phase 2, which will be available in another major Cisco  IOS software release, will allow a user to carry credentials to other services, such as Telnet, without having to reauthenticate.)
A Cisco white paper explaining Kerberos in more detail can be found on the World Wide Web (you need to be a registered CCO user) at:
http://www.cisco.com/warp/public/789/1.html
The server resides on a central computer typically at the user's site. The clients reside in the dial-up access servers and can be distributed throughout the network. The RADIUS client is available in Cisco  IOS Release  11.1.
Cisco's implementation of RADIUS is currently defined in draft documents at ftp.livingston.com:pub/radius/draft-ietf-radius-radius-02.txt. Cisco's implementation is based on this version of the draft. Cisco will attempt to keep current with any newer drafts issued. A sample RADIUS server can be obtained from Livingston's FTP site.
RADIUS is configured on the network access server much like TACACS+.

Network Management Features

This section describes the network management feature that is new in the initial release of Cisco  IOS Release  11.1.

Note As a security precaution, the packet capture group captures only useful packet header information; data payloads are not captured.
All Cisco  IOS software images that do not explicitly include full RMON support include RMON alarm and events groups. These groups can be coupled with existing Cisco MIB variables and allow customers to set thresholds and alarms on any MIB variables supported by Cisco.
RMON not only provides visibility of individual nodal activity, it allows the monitoring of all nodes and their interaction on a LAN segment. RMON used specifically as an agent in the router allows network managers to view either only traffic that flows through the router or all Ethernet segment traffic not necessarily destined for the router.
An RMON console application such as Cisco Traffic Director or NETscout Manager by Frontier Software Development, Inc., is required to take full advantage of the embedded RMON's network management capabilities.

Security Features

This section describes the security feature that is new in the initial release of Cisco  IOS Release  11.1.

Before Lock-and-Key access, IP access lists were created and maintained by manually defining lists on a router and distributing them to all other routers in the network. In networks with many hosts, this task could consume time and resources. Access lists do not provide any challenge mechanism beyond a static network address, making it possible for an unauthorized user to access network resources through any authorized network address. The Lock-and-Key access feature is an ideal solution for the proliferation of remote networks. Lock-and-Key access supports various WAN technologies such as ISDN, Frame Relay, X.25, dial-on-demand routing (DDR), and Point-to-Point Protocol (PPP).
When a user Telnets to a router configured with Lock-and-Key access, the software challenges the user to respond to a login and password prompt before placing a temporary entry in the dynamic access list. The network administrator can dictate an idle time-out or an absolute period for authorization and reauthorization.
Lock-and-Key access provides the following benefits:
Lock-and-Key access requires Telnet. Standard Telnet is the required application on the host platform that activates a Lock-and-Key session.
Further information on Lock-and-Key access can be found on the World Wide Web in the Cisco  IOS Lock and Key white paper (Product Bulletin 308) at http://www.cisco.com/warp/customer/417/66.html. (You need to be a registered CCO user.)

Important Notes

This section describes warnings and cautions about using the Cisco  IOS Release  11.1 software. This section discusses these topics:

BSC and SDLC Commands in Release  11.1(2)

In Release  11.1(2), the bsc fdx and sdlc hdx commands were deprecated and replaced by the full-duplex and half-duplex commands, respectively. The deprecated commands continue to be supported in Release  11.1(2) and later, but might not be supported in the next major release of Cisco  IOS software.

Upgrading to a New Software Release

If you are upgrading to Cisco  IOS Release  11.1 from an earlier Cisco  IOS software release, you should save your current configuration file before installing Release  11.1 software on your router.

Channel Interface Processor (CIP) Microcode

Starting with Cisco  IOS Release  11.1, CIP microcode is available as a separate image, unbundled from the Cisco  IOS image. CIP microcode (for the CIP or second-generation (CIP2)) resides only in router Flash memory as multiple files. The router loads a "kernel" to the CIP (based on hardware revision), and the CIP selectively loads and relocates the software it requires from the router's Flash memory. The CIP image is available on pre-loaded Flash memory cards, on floppy diskette, or via FTP from Cisco. Every version of Cisco  IOS Release  11.1 has a corresponding version of CIP microcode. Refer to the Channel Interface Processor (CIP) Microcode Release Note and Microcode Upgrade Requirements publication (Document Number 78-4715 -xx) for information about the recommended pairs of Cisco  IOS Release  11.1 and CIP microcode.

The CIP loader has the following effect on the router's system memory requirements:

Consider the following before you use the CIP loader:

When the CIP image is copied to an existing Flash memory card, the existing flash copy commands are used, just as before. If a CIP image other than the default for the release is being used, then the microcode cip flash configuration command must be issued.

The show microcode command has been expanded to display the default CIP image name for the Cisco  IOS release.

Note The router must already be running Cisco  IOS Release  11.1 before performing a copy of the CIP image to Flash memory, because the CIP image must be "exploded" from the single image file on the TFTP server to multiple files in Flash memory. This capability is added in Release  11.1.

There are a number of ways to determine what is loaded on each CIP:

Multiple CIP cards of different hardware revisions can run in the same router.

Cisco 7500 Series High System Availability (HSA)

To successfully use the HSA feature, you should take note of the following:

%RSP-3-INVRSP_IPC: Slave RSP slot x not supported with VIP slot y, crashing router
[CSCdi60891]

VLAN Routing

Support for VLAN routing is not available in Release  11.1(1). Support for this feature is available in Release  11.1(2). VLAN routing allows Inter-Switch Link (ISL)-encapsulated IP, IPX, and transparently bridged traffic to be routed or bridged to any other VLAN or native interface.

Netbooting from VIP

To netboot from Ethernet or Fast Ethernet ports on a VIP card the system must contain version 11.1 boot ROMs. If the system contains version 11.0 boot ROMs, you can work around this requirement by using the boot bootldr device: filename global configuration command to load a bootstrap image from Flash memory.

Source-Route Bridging (SRB) over FDDI

This feature supports forwarding of source-route bridged traffic between Token Ring and FDDI interfaces on the Cisco  7000, Cisco  7010, and Cisco  7500 series routers. Previously, the only way to transport SNA and NetBIOS over FDDI was with remote source-route bridging (RSRB), which is either fast switched (direct or Fast-Sequence Transport (FST) encapsulation) or process-switched (TCP encapsulation). With SRB over FDDI, traffic can be autonomously switched, greatly improving performance for SRB traffic that uses FDDI as a backbone. This feature eliminates the need for RSRB peer definitions to connect Token Ring networks over the FDDI backbone.

Note SRB over FDDI does not support RSRB traffic forwarded to RSRB peers. Routers that have connections to local Token Ring networks as well as RSRB connections to remote networks cannot use this feature. The work around is to move the RSRB connections to routers that are not connected to the FDDI backbone.

Enabling IPX Routing

The Token Ring interface is reset whenever IPX routing is enabled on that interface.

Using AIP Cards

Cisco  7000 series ATM Interface Processor (AIP) cards that support E3, DS3, or Transport Asynchronous Transmitter/Receiver Interface (TAXI) connections and that were shipped after February 22, 1995, require Cisco  IOS Release  10.0(9), 10.2(5), 10.3(1), or later.

Booting Cisco  4000 Routers

You must use the Release  9.14 rxboot image for Cisco  4000 routers because the Release  11.0 rxboot image is too large to fit in the ROMs. (Note that rxboot image size is not a problem for Cisco  4500 routers.) However, because the Release  9.14 rxboot image does not recognize new network processor modules, such as the Multiport Basic Rate Interface (MBRI), its use causes two problems:

Bad interface specification
No interface specified - IP address
Bad interface specification
No interface specified - IP address

Using LAN Emulation (LANE)

Note the following information regarding the LAN Emulation (LANE) feature:

Forwarding of Locally Sourced AppleTalk Packets

Our implementation of AppleTalk does not forward packets with local-source and destination network addresses. This behavior does not conform to the definition of AppleTalk in Apple Computer's Inside AppleTalk publication. However, this behavior is designed to prevent any possible corruption of the AppleTalk Address Resolution Protocol (AARP) table in any AppleTalk node that is performing MAC-address gleaning.

Using Source-Route Transparent Bridging (SRT) and Source-Route Bridging (SRB) on Cisco  2500 and Cisco  4000 Routers

Certain products containing the Texas Instruments TMS380C26 Token Ring controller do not support SRT. SRT is the concurrent operation of SRB and transparent bridging on the same interface. The affected products, shipped between March  30, 1994, and January 16, 1995, are the Cisco  4000 NP-1R, Cisco  4000 NP-2R, Cisco  2502, Cisco  2504, Cisco  2510, Cisco  2512, Cisco  2513, and Cisco  2515.

Units shipped before March 30, 1994, or after January 16, 1995 are not affected. They use the Texas Instruments TMS380C16 Token Ring controller, which supports SRT.

SRT support is necessary in two situations. In one, Token Ring networks are configured to SRB protocols such as SNA and NetBIOS, and they transparently bridge other protocols, such as IPX. In the other situation, SNA or NetBIOS uses SRB and Windows NT is configured to use NetBIOS over IP. Certain other configuration alternatives do not require SRT (contact the Technical Assistance Center for more information).

As of Release  10.3(1), SRB in the following Cisco  IOS features sets is no longer supported: IP, IP/IPX, and Desktop. To use SRB, you need one of the following feature sets: IP/IBM base, IP/IPX/IBM base, IP/IPX/IBM/APPN, Desktop/IBM base, Enterprise, or Enterprise/APPN. In most non-IBM Token Ring environments, the multiring feature in IP, IP/IPX, and Desktop eliminates the need for IP/IBM base, IP/IPX/IBM base, IP/IPX/IBM/APPN, Desktop/IBM base, Enterprise, or Enterprise/APPN.

Release  11.1(5a)

After the release of Cisco  IOS Release  11.1(5), a caveat was discovered within the Cisco  IOS rsp- images. It was determined that this caveat was significant enough to merit a rebuild of the rsp- images. The rebuild includes the caveat fix and is renumbered to 11.1(5a).

This defect is bug CSCdi66673 and is described as follows:

When Ethernet runt packets are received by Cisco 7500 series router processors (RSP1, RSP2, or RSP7000), a Reserved Exception crash or a QAERROR error will occur. When either of these problems happens, a switching complex restart is forced. The Reserved Exception crash has the following output:

Release  11.1(5a) and all subsequent releases of Cisco  IOS software, including Release  11.1(6), include the fix for this caveat.

Release  11.1(11a)

After the release of Cisco  IOS Release  11.1(11), caveats were discovered within the Cisco  IOS rsp- images. It was determined that these caveats were significant enough to merit a rebuild of the rsp- images. The rebuild includes the caveat fixes and is renumbered to 11.1(11a).

The defects are bugs CSCdi67315, CSCdj08722 and CSCdj09576 and are described as follows:

Release  11.1(11a) and all subsequent releases of Cisco  IOS software, including Release  11.1(12), include the fix for these caveats.

ATM Multipoint Signaling

Prior to Cisco IOS Release 11.1(13) and 11.2(8), the atm multipoint-signaling command was used on the main interface and affected all subinterfaces. For Release 11.1(13), 11.2(8) and later releases, explicit configuration on each subinterface is required to obtain the same functionality. Refer to bug CSCdj20944, which is described as follows:

Clients on different subinterfaces can have different behavior. Specifically 1577 requires point-to-point, and PIM allows point-to-multipoint. The command should be on a per subinterface basis.
Users will have to enable the atm multipoint-signaling command on all subinterfaces that require it. Previously, they only needed to enable it on the main interface.

Release  11.1(13a)

After the release of Cisco  IOS Release  11.1(13), caveats were discovered within the Cisco  IOS software. It was determined that these caveats were significant enough to merit a software rebuild. The rebuild includes the caveat fixes and is renumbered to 11.1(13a).

The defect is bug CSCdi73194. Related bugs are CSCdj25806, CSCdj25905, CSCdj26494, CSCdj26898, CSCdj28362, CSCdj30980, and CSCdj32710. CSCdi73194 is described as follows:

Release  11.1(13a) and all subsequent releases of Cisco  IOS software, including Release  11.1(14), include the fix for these caveats.

Caveats for Release 11.1(1) through 11.1(24)

Basic System Services

The only known workaround is to unconfigure the old interface processor before replacing it with the new one. Sometimes, it might even be necessary to issue a write erase command, reboot the router, and then redefine the existing interfaces to completely remove all configuration traces of the old interface processor. Once the information that is displayed by the show commands is self-consistent, the newly inserted interface processor behaves normally. [CSCdi49800]

Since PVC is always active in Cisco IOS Release 11.1, it should not have this problem. OSPF hello will always be sent down the PVC without being rejected.

 IP Routing Protocols



The loss of the route is due to sporadic line congestion (packet drops) and/or an SIA event on the same link as the neighbor occurring while a route is active. On very rare occasions, this can result in a lost acknowledge packet and a retransmission of the reply packet. For the failure to occur the retransmitted reply must have a valid metric.


A workaround is to issue the command clear ip route *. [CSCdj73617] 





 ISO CLNS



Specifically, this can happen when the external route is known via the backup path, then becomes known via multiple optimal paths at about the same time, followed later by the loss of the optimal paths. The problem disappears when an SPF is run for any reason.


A workaround is to force an immediate SPF on the router (for example, by issuing the commands shutdown, no  shutdown on a loopback interface running ISIS). Note that this can be done on any router in the same area. [CSCdk05616]

%VIP2 R5K-1-MSG: slot3 System exception: sig=20, code=0x..., context=0x... 


When this signal is present, the contents of the VIP crashinfo file are required for proper analysis.


When running an image that does not have CSCdj93505 integrated into it, the parity error may manifest in different ways. CSCdj20187 documents one such example. [CSCdj93505] 





 Caveats for Release 11.1(1) through 11.1(18)

 
 This section describes caveats (possibly unexpected behavior) of Cisco  IOS Release  11.1(18). These caveats also apply to Releases 11.1(1) through 11.1(17) (unless otherwise noted).


 For more caveats of Release  11.1(18) and earlier 11.1 releases, see all the preceding caveat sections.


 Only serious caveats are described in these release notes. For the complete list of caveats against this release, access CCO or use the Documentation CD-ROM as described in the sections "Cisco Connection Online" and "Documentation CD-ROM" at the end of this document.


 All the caveats listed in this section are resolved in Release  11.1(19).


 Basic System Services



%SYS-3-SUPNONE: Registry 23 doesn't exist 


[CSCdj19276]





If this problem occurs, the configuration NVRAM of both the master and slave RSP will be invalid after a reboot and must be recovered manually as follows:


1. Send an RS-232 break to the console of both the master and slave.


2. Issue the ROM monitor confreg command on the master and slave to ignore the system configuration.


3. Issue the ROM monitor reset command on the master and slave to boot a slave-capable image.


4. On the master console, copy a good configuration file from Flash memory or TFTP into running-config.


5. Turn off the 0x40 bit in the configuration register by issuing the show version EXEC command and the config-register configuration command.


6. Issue the reload command to reload the master.


A workaround is to store the configuration in Flash memory. For example, issue the copy running slot0:config or write memory commands while configured with boot config slot0:config, service compress, and boot buffersize n, where n is at least three times the configuration size in bytes. In this case, the write memory command will work slowly - 10 minutes elapsed time for each 128k block of configuration text. [CSCdj63926] 





It is also possible for this problem to occur on HDLC serial lines and cause instability due to HDLC keepalive packets being delayed.


This is a rare occurrence and has only been seen with very large IPX SAP updates sent over a slow-speed circuit. The size of updates necessary to cause this problem on a 56 kbps circuit is around 3000 SAPs. The problem is more likely to occur when there is data traffic at near-line capacity on the circuit.


It is theoretically possible for other routing or control packets such as OSPF Link State Advertisements (LSAs) or NLSP Link State Packets (LSPs) to cause the same effect in a period of severe routing instability in a large network with many Frame Relay subinterfaces. The issue is less likely to be seen when Weighted Fair Queuing is used on the serial interface rather than First In First Out (FIFO) queuing. Please note that there are many other possible causes of instability of Frame Relay or serial circuits and the manifestation of this particular caveat in operating networks is unlikely.


If the issue is seen because of very large IPX SAP updates, the workaround is to configure an ipx output-sap-delay and ipx output-rip-delay that is larger than the propagation delay of a SAP packet across the circuit. A delay of 110 ms is sufficient for a 56K circuit. The possibility of seeing this caveat with very large IPX SAP updates was introduced by CSCdj18092. [CSCdj91667] 




 IBM Connectivity



There is currently no known workaround [CSCdj77914] 





A workaround for this is to disable LNM on the router by issuing the command lnm disable. [CSCdj82340]

 IP Routing Protocols



The loss of the route is due to sporadic line congestion (packet drops) and/or an SIA event on the same link as the neighbor occurring while a route is active. On very rare occasions, this can result in a lost acknowledge packet and a retransmission of the reply packet. For the failure to occur the retransmitted reply must have a valid metric.


A workaround is to issue the command clear ip route *. [CSCdj73617] 





Workaround is to set some of the interfaces passive and not change them to active. [CSCdj81611] 





 Novell IPX, XNS, and Apollo Domain



A workaround is to run with fastswitching disabled or clear the IPX route cache when this is noticed. [CSCdj59732] 




 Wide-Area Networking



It may be possible to work around the problem by using the mtu command to select a smaller MTU/MRU value for the interface, but this will only work if the remote peer agrees to negotiate the smaller value. Another workaround is to downgrade to a version of software that does not contain the CSCdi92482 patch.


To verify the problem, issue the debug ppp error command and search for a debug message of the following form:


Se6/0/0:23 PPP: Packet too large, size = 1509, maxsize = 4, protocol = 0x003D


[CSCdj82427] 





lane fixed-config-atm-address 
lane auto-config-atm-address 





A message of the following form will be generated:


%LANE-4-LECS_WARN: ATM1/0: can't register 
47.00790000000000000 0000000.00A03E000001.00 with signalling 
(duplicate address ?)


As a workaround, use only a single LECS address configuration or do not enable logging timestamps if multiple LECS addresses are required. [CSCdj83816] 





%SYS-3-INVMEMINT: Invalid memory action (malloc) at interrupt level

These messages may repeat, and the RSP may also hang as a result. An image with CSCdj85257 integrated in will resolve these secondary problems and the RSP will recover normally. CSCdj85257 will not resolve the original CyBus error, however. [CSCdj85257]





When running an image that has CSCdj93505 integrated into it, crash output for VIP2 products with a signal value of 20 indicates that a cache parity error condition was detected.


%VIP2 R5K-1-MSG: slot3 System Reload called from 0x..., context=0x... 
%VIP2 R5K-1-MSG: slot3 System exception: sig=20, code=0x..., context=0x... 


When this signal is present, the contents of the VIP crashinfo file are required for proper analysis.

 Caveats for Release 11.1(1) through 11.1(17)

 
 This section describes caveats (possibly unexpected behavior) of Cisco  IOS Release  11.1(17). These caveats also apply to Releases 11.1(1) through 11.1(16) (unless otherwise noted).


 For more caveats of Release  11.1(17) and earlier 11.1 releases, see all the preceding caveat sections.

 All the caveats listed in this section are resolved in Release  11.1(18).


 Basic System Services



This method is better than having to enter the test rsp cache memd uncached EXEC command every time the router is booted. 


This configuration command can be used as a workaround for problems like CSCdj52309 and CSCdj70296. 


To restore the MEMD caching policy to the original write-through policy, issue the memory cache-policy io write-through command. To determine what memory cache policies are currently configured on your router, use the show rsp command. [CSCdj33812]

 Interfaces and Bridging



For example, on a Cisco 7200 series router with Fast Ethernet port adapter 6/0, the problem looks like the following: 


configure terminal 
Enter configuration commands, one per line. End with CNTL/Z. 
int f 6/0 
media ? 
MII Use MII connector <--- Only MII, no RJ45 


This problem appears on the following platforms in the specified Cisco IOS releases:


A workaround is available on most of the platforms and Cisco IOS images; to configure for RJ45, use the no media-type MII command. The following is an example of the workaround on a Cisco  7500 series router with Fast Ethernet port adapter 0/0/0: 


configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.
int f 0/0/0 
no media MII <--- switch to RJ45 


This workaround is available on the following platforms running the specified Cisco IOS releases:


Platform defaults are correctly preserved for all platforms and images that default to RJ45. The following platforms running the specified releases default to RJ45:


This problem first appeared in the following releases: 11.1(16.2), 11.1(15.3)CA, 11.2(10.4), 11.2(10.4)P, 11.3(1.2), and 11.3(1.2)T.


This problem was fixed in the following releases: 11.1(17.1), 11.1(17)CA, 11.2(11.4), 11.2(11.4)P, 11.3(1.5), and 11.3(1.5)T. [CSCdj75983]





As a workaround, use the PA-FE-TX or PA-FE-FX interfaces for ISL traffic or use Releases 11.3(1) or 11.3(1)T. [CSCdj79992]

 Caveats for Release 11.1(1) through 11.1(16)

 
 This section describes caveats (possibly unexpected behavior) of Cisco  IOS Release  11.1(16). These caveats also apply to Releases 11.1(1) through 11.1(15) (unless otherwise noted).


 For more caveats of Release  11.1(16) and earlier 11.1 releases, see all the preceding caveat sections.


 Only serious caveats are described in these release notes. For the complete list of caveats against this release, access CCO or use the Documentation CD-ROM as described in the sections "Cisco Connection Online" and "Documentation CD-ROM" at the end of this document.


 All the caveats listed in this section are resolved in Release  11.1(17).


 Basic System Services



For example, a problem was found with a Cisco  7500 series using a large number of Fast Ethernet and/or Ethernet interfaces and one or more FDDI interfaces. The pool of packet memory should have allocated 80 percent of the memory to the Ethernet and Fast Ethernet interfaces, which use an MTU of 1536. Instead it received 20 percent of the memory, and the lone FDDI interface with MTU  4512 got 80 percent of the packet memory. 


The problem occurred with 55 Ethernet, 6 Fast Ethernet, and 1 FDDI network interfaces. The problem did not occur with fewer interfaces, specifically 36 Ethernet, 5 Fast Ethernet, and 1 FDDI interfaces. 


The problem may show up as a high number of input drops on some router interfaces. [CSCdj55428]




 IBM Connectivity



The problem typically occurs when NetBIOS is utilized to allow workstations to communicate between Ethernet and Token Ring. It will also occur when SNA is used. 


The workaround is to disable fast switching by using the command no source-bridge transparent fastswitch or configure the end stations to use frames with a payload of less than or equal to 1500 bytes. [CSCdj62385]

 Interfaces and Bridging



A workaround for the second problem is to turn off CDP globally or on individual interfaces. In this case, the user can turn off CDP on the serial interface before adding or removing subinterfaces. [CSCdj07291]





This problem should have minimal impact on the performance of a multidrop line because a FEP usually resorts to individual polling. [CSCdj33392]





The problem only affects the mid-range and low-end platforms. [CSCdj41666]

 IP Routing Protocols



The router can be forced to install the matching route by using the clear ip route * command. [CSCdj32471]





This issue occurs when the Proteon router's Internal Address is advertised as a Host Route, not a network, in the router's LSA. A Host Route is represented as a Type 3 link (Stub Network) whose link ID is the host's IP address and whose Link Data is a mask of all ones (0xffffffff). This Host Route is advertised into all OSPF areas. [CSCdj56079]





The nature of the defect is that it will only occur after a dynamic event. If redistribution is manually configured, EIGRP will initially reflect correct information in the topology table; however, after any sort of dynamic event, the topology table becomes invalid and routing updates sent are inaccurate. [CSCdj58676]





Incoming packets on the ATM interface and outgoing packets on the serial interface also experience this problem. However, incoming packets on the serial interface and outgoing packets on the ATM interface do not experience this problem. 


It seems that incoming packets are not fast switched. [CSCdj59076]

During normal behavior, the point-to-point subinterface should go down when the primary DLCI fails. If a secondary DLCI fails, the subinterface stays up, but traffic destined for that DLCI only will fail. [CSCdj11056]





The workaround is to remove the ip tcp header-compression or ppp multilink command. [CSCdj53093]

The problem is related to the way DLSw backup peers are configured. This problem only occurs if the local router is configured with backup peer commands and the remote router also has a configured peer and is not promiscuous. 


The workaround is to remove the DLSw backup peer configuration. [CSCdj21664]





If the downstream device never responds to the outstanding bind, the DLUR router will wait indefinitely and not free the local-form session ID (lfsid). This may cause a situation in which the host tries to reuse a lfsid after it has sent an unbind request, but the DLUR rejects the new bind request because it believes that this lfsid is in use. If the host continuously tries to use this lfsid which the DLUR believes is in use, then no new sessions can be established. This problem occurs only when the downstream device does not respond to a bind request. [CSCdj30386]

%APPN-7-APPNETERROR: State Error lcb: 60C05CC0 pcid: DA839C70FB1548CB row: 22 col: 0 


This problem occurs when two links are active to the same node, the CP-CP sessions are split between these two links, and the link with contention loser is stopped. 


The APPN subsystem should be stopped and restarted to clear this problem. If the CP-CP sessions are between the router and the host, terminating either CP-CP session on the host will also clear this problem. [CSCdj33718]

As a result, the first ICMP ARP broadcast message fails to reach the destination when ping is used. [CSCdj21365]





The encapsulation fddi command should only be used with bridging enabled. 


A workaround is to use the no bridge-group 1 command to disable bridging. [CSCdj24479]





The workaround is to use RFC1483 over a PVC using a multipoint subinterface with a map list defined. Using the map-group command on a multipoint subinterface does not exhibit breakage. 


To determine if you have this bug, enter the show arp command. If there is an entry for the other end of the PVC showing "incomplete" for the MAC address, then you are affected by this caveat. [CSCdj34217]





 IP Routing Protocols



The workaround is not to enter a key longer than 19 characters, either encrypted or not. 


The same problem happens with the ip ospf message-digest key-id md5 key command. In this case, the key length should not be longer than 36 characters. [CSCdj37583]





A workaround is to configure the loopback interface, whose address is greater than any other address on the router. [CSCdj37962]




 LAT



%LAT-3-BADDATA: Tty124, Data pointer does not correspond to current packet

In Cisco IOS Release 11.0(11) the software accepts the remote peer's "Her" proposed address regardless, and the "Her" address is subsequently added to the IP routing table as a host route. 


With Cisco IOS releases later than 11.0(11) the software will check the "Her" address against the corresponding dialer map and if the address is different than the IP address detailed within the dialer map, a NAK will be sent and the dialer map IP address will be added as a host route in the IP routing table.

To work around this problem, do one of the following: 





This problem occurs because of a race condition when doing DNS name query and DNS name cache is removed in the middle of the process. 


There is no workaround on the router side. On the DNS server side, configuring DNS TTL to be one minute or longer may work around this problem. However, this workaround may not be acceptable for some applications. [CSCdj16824]

A router may experience this problem after displaying several messages when the output buffer was full. If the crash was related to displaying "incomplete definition in configuration" warnings, the workaround is too remove these incomplete definitions. [CSCdj26701]





Because other network events (link outages, and so forth) can trigger a node to send a TDU, this problem will not necessarily appear exactly after a 60-day uptime -- it may occur much later or not at all. However, any APPN router running in the network for over 60 days is at risk for seeing this problem. 


Stopping and restarting APPN will work around this problem until the next timer wrap, which can be up to 45 days, but may be less depending on the current value of the timer. Reloading the router will reset the timer and avoid the problem for an additional 60 days. [CSCdj29014]





Caveat CSCdi77040 provides a fix for this problem in the system side. This caveat provides the corresponding fix for APPN. [CSCdj30552]





When memory is exhausted, the APPN subsystem may stop or the router may reload. [CSCdj33429]

[CSCdj21944]





To work around this problem, use the async mode dedicated command if no login is required. If a login is required, configure the no flush-at-activation command, change the q2 register in the modem database, and configure the modem autoconfigure type command. [CSCdj25443]





The following error message can be seen scrolling on the console if the router is in the above state: 


%X25-4-VCLOSTSYNC: Interface TCP/PVC, VC 0 TCP connection corrupted 


This does not seem to occur in a normal XOT switching environment. [CSCdj25846]





The workaround is to configure the asynchronous interfaces using the async mode dedicated command. Sometimes, adding a second or two delay in the automated dialer's script also fixes the problem. [CSCdj26647]

In some application environments, certain 3270 emulators will not direct a test poll to a specific media access control address and will use an all Fs address to create the frame. It is this all Fs frame in an SRB configuration that will not be forwarded by the router. This configuration impacts workstations that are attempting to connect to host devices. The broadcast frame will never leave the local ring.


Most emulators will use the destination media access control address of the host device to create a frame containing the test poll. With some proprietary implementations, the MAC address of the host device does not have to be known by the end device. [CSCdj13563]

Such CyBus errors with code 78 and that point to a virtual address FE0000 or have MD errors similar to the above have two known causes. First, if there are HIPs in the router and on the bus reporting the CyBus error, if applicable, there is a race condition with the HIP microcode on an oversubscribed bus. The workaround on dual-CyBus platforms is to move all the HIPs onto a CyBus that is not oversubscribed. Second, these errors can be caused by the failure of a marginal CI arbiter board or an RSP board. As a result of this problem, all interfaces are reset, causing forwarding to be stopped for a few seconds. [CSCdj06566]

Encapsulated bridging does not work on a Cisco 7500 series router. To bridge between an AGS+ and a Cisco 7500 series router, you must use CSC-C2FCIT cards in the AGS+ and translational bridging. 


The big disadvantage of using encapsulated bridging is that it cannot use the hardware bridge filtering capabilities of the CSC-C2FCIT cards, which have a CAM built into them that is used to do bridge filtering on the card. When encapsulated bridging is used, the main processor must do all bridge filtering. This means that one busy encapsulated bridging FDDI network can consume the entire bandwidth of the router's main processor, just for bridge filtering. Therefore, Cisco discourages the use of encapsulated bridging. [CSCdi46862]

 Basic System Services



To avoid this problem, you should upgrade all IOS Release  11.1 RSP-based systems to Cisco  IOS Release  11.1(8), or a later 11.1 release.


For those systems that cannot be upgraded, you can avoid this problem by disabling Backing Store, Fair Queuing, and UDP turbo flooding.


Disable Backing Store and Fair Queuing on each interface with the commands no transmit-buffers backing-store and no fair-queue. Backing Store defaulted to OFF in images beginning with 11.1(4.1). However, it is important to look at the current configuration. An image configured before Backing Store defaulted to OFF may have it ON for router interfaces.


Disabling UDP turbo flooding is a workaround required for 11.0 and later major releases. UDP turbo flooding is OFF by default in all releases, however, you should ensure that it is turned OFF in the current configuration. The command to disable UDP turbo flooding is no ip forward-protocol turbo-flood.

This problem was introduced by some changes to the Token Ring interrupt handler in Release  11.0 and later. 


There is no workaround for the diversion, though the flushing can be avoided by raising the explorer maxrate value to some high number. However, this may cause instability in the network. [CSCdi59090]

The error message "%SYS-2-INPUTQ: INPUTQ set, but no idb, ..." will appear.

The software fix for this problem passes UI frames through the border peer relay network. [CSCdi54796]





The low speed asynchronous/synchronous serial interface may drop SDLC frames with this configuration. The symptoms of this problem are poor performance and excessive Cyclic Redundancy Check (CRC) errors on the interface (as seen via the show interface command).


The fix for this problem requires: hardware version 00000002 and a software fix for this defect, which is incorporated into Cisco  IOS Release  11.0(9) and 11.1(4), and later.


All Cisco 2520, 2521, 2522, and 2523 routers manufactured before May 24, 1996 are subject to this problem.


To identify whether your router is affected, issue a show version command. The hardware revisions that are subject to the problem are "00000000" and "00000001." Hardware revision "00000002" contains the hardware fix that resolves this problem [CSCdi57040]:




cisco 2520 (68030) processor (revision E) with 4096K/2048K bytes of memory. 
Processor board ID 02351913, with hardware revision 00000002 
 




 Interfaces and Bridging



In addition to the hardware requirement, the fix for this bug that is in Release  11.0(8) and 11.1(4) and later releases requires that you allow a minimum of 15 seconds to elapse between OIR events. Removal of one interface counts as one event, and insertion of one interface counts as one event. 


If your MIP hardware isn't at least hardware version 1.1, it will not EOIR or OIR correctly! 


Failure to provide this time for the router to stabilize between OIR events can result in the reset performed for one event corrupting the reset performed for another event, which could require interfaces to be reconfigured or reinitialized manually. This reset requires even more time if additional channel-groups are defined within the router. The time between OIR events should be increased to as much as 30 seconds if three or more MIP cards are fully channelized in the router. While the corruption of this reset activity might occur only occasionally if OIR events are too closely timed, it is mandatory to allow the correct interval to guarantee the benefits of EOIR/OIR. [CSCdi46137]





For example, change: 


access-list 116 permit ip any any 
access-list 116 permit tcp any any gt 1023 
access-list 116 permit tcp any any eq smtp 


to: 


access-list 116 permit ip any any

A workaround is to either disable IS-IS before removing the static route or enable IS-IS on the interface before removing the static route. [CSCdi56815]





A workaround is to filter out the ESH packets using the clns adjacency-filter es configuration command in conjunction with an appropriate filter set (which should specify a wildcard [**], in the last byte of the address). [CSCdi58621]

In addition, when the serial line is configured to be frame-relay intf-type dce or frame-relay intf-type nni, if a frame-relay intf-type command is entered after the desired PVCs have been configured, then the router will fail to send the correct LMI Full Status message. [CSCdi52339]

To workaround, reconfigure the remote device with the correct SDU size. [CSCdi57676]

Clients on LANs with no server can connect correctly, because the router answers the GetNearestServer request. However, whenever a Novell server resides on the same LAN as the client, the client will not be able to connect to any remote services.

A possible workaround is to set the dialer idle-timeout value on the BRI routers connected to NET3 switches higher than the timeout value of the other router or routers connecting via ISDN. This workaround assumes the other router or routers do not have BRIs connected to NET3 switches, because they would have the same problem. This workaround also requires knowledge of the dialer idle-timeout value configured on the other router or routers. 


The problem does not occur if the call hangup is initiated by the ISDN network rather than the BRI router connected to a NET3 switch. 


Releases  11.0(2.1), 10.3(6.1) and 10.2(8.5) were the first software versions to exhibit the problem. [CSCdi46668]





To prevent this behavior, remove the cause of the line errors or increase the hold-queue size. [CSCdi48424]





If you choose to continue to use Cisco  IOS Release  11.0(5), Release  11.1(1) or earlier releases, the Catalyst  5000 requires ATM software Release  1.1. [CSCdi49790]





If, however, the original interface comes back up before the backup connection is complete, the floating static route will have been removed and a neighbor route will be added to the peer address. This route will carry routing updates to the peer over the backup connection and thus reset the idle timeout with each packet. As a result, the backup interface will never disconnect. This behavior was added with Release  11.0(3). [CSCdi50489]





 Microcode Software

 
 For Cisco 7000 and 7500 series platforms, microcode software images are bundled with the Release  11.1 system software images (features sets). The only exceptions are the Channel Interface Processor (CIP) microcode and the Versatile Interface Processor (VIP) microcode. CIP microcode is unbundled in all system software images. VIP and VIP2 microcode is contained only in feature sets that have "VIP" in the feature set name.


 Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software onto all the interface processor boards.


 Table 16 lists the microcode versions bundled into Release  11.1(17) software images for the Cisco  7000 series platforms.


 Table 17 lists the microcode versions bundled into Release  11.1(17) software images for the Cisco  7500 series platforms.



Note For the Cisco  7000 series, all boards must use the Level 10 (or greater) microcode that is bundled (except CIP) with the system image.
