Router Products Release Notes for Cisco IOS Release 11.0


March 19, 2001


Note      Cisco IOS Release 11.0 is scheduled to go End of Engineering (EOE) July 2000. End of Engineering refers to the date of the last scheduled maintenance release (TAC support is still available after End of Engineering). Cisco IOS Release 11.0 will be supported through January 2001 for any Y2K issues. These release notes will be the last release notes published for Cisco IOS Release 11.0.


These release notes describe the features and caveats for Cisco IOS Release 11.0 up to and including Release 11.0(22a). They include all routing and protocol translation features.

Cisco IOS Release 11.0(11) and all subsequent 11.0 releases are deemed "Generally Deployable." Cisco believes Release 11.0 is suitable for deployment anywhere in the network where the features and functionality of the release are required.

Introduction

These release notes discuss the following topics:

Documentation

Cisco IOS Release 11.0 router software functionality and configuration information is documented in three publications. (Release 11.0 access server software is documented separately.) Refer to these publications for complete information about using and configuring Release 11.0 software:

There are also five supporting documents:

All 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, within the Cisco IOS Software Configuration database, select Cisco IOS Release 11.0.

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 Documentation page to find the Cisco IOS Software Configuration database. Then, select Cisco IOS Release 11.0.

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 11.0 Releases on these Cisco platforms, except as noted:


Note      To use Release 11.0 features, AGS+, MGS, and CGS routers must have CSC/4 processor cards and 9.1(8)-level (or later) system ROMs for netbooting.



Note      Cisco IOS Release 11.0 is the last release supported on the Gateway Server Product Line, specifically the AGS+/4, AGS/4, MGS/4, and CGS/4 platforms. Later releases will not run on these platforms.


For each of the supported platforms, Release 11.0 enables your Cisco device to use certain LAN and WAN interfaces and data rates.

For a list of interfaces supported by Release 11.0 for each platform, see Table 1 and Table 2.

Table 1 summarizes the LAN interfaces supported on each platform.

Table 2 summarizes the WAN data rates and interfaces supported on each platform.

For each platform, you can use any of the interfaces or data rates labeled "Yes" in the table. Release 11.0 does not support interfaces or data rates that are not labeled "Yes."

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 3 through Table 9 (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.

Table 3 summarizes the feature sets and optional licenses for the Cisco 7500 series platforms.

Table 4 summarizes the feature sets and optional licenses for the Cisco 7000 series, AGS+, MGS, and CGS platforms.

Table 5 summarizes the feature sets for the Cisco 2500 series platforms.

Table 6 lists the features sets for the Cisco 4000 series platforms.

Table 7 summarizes the software for the Cisco 3000 series platforms.

Table 8 summarizes the software for the Cisco 1003 and Cisco 1004 ISDN routers.

Table 9 summarizes the software for the Cisco 1005 router.

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 11.0 features, you need to have the code or main system memory as listed in Table 10. 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 10 are minimum requirements. Your specific hardware configuration and the software features you chose to deploy could require you to have more memory.

RAM

For Cisco 2500 access servers (Cisco 2509-2512) and for Cisco 2520-2523 platforms, 4 MB DRAM is the minimum recommended.

The Cisco 4500-M requires 16 MB DRAM when an MBRI, NP-CT1, or NP-CE1 Network Processor Module is installed in the chassis.

The minimum recommended main memory is 24 MB for most applications.

New Features in Release 11.0(11) and Later 11.0 Releases

There are no new features added in Release 11.0(11) or in later 11.0 releases. Cisco IOS Release 11.0(11) and later 11.0 releases are considered Generally Deployable (GD). To maintain the stability required in a GD release, no new features are added.

New Features in Release 11.0(10)


Note      The first few maintenance releases of each new Cisco IOS software release may deliver additional new features. When deciding whether to deploy a new release, you should weigh the importance you place on maximizing product capability versus maximizing operational stability. An early release of software should always be tried in a test network before being deployed in a production network.


The following enhancements were added to Release 11.0(10):

New Feature Sets for CIP2

Cisco IOS Release 11.0(10) supports four new feature sets— two for the Cisco 7000 series and two for the Cisco 7500 series routers. The new feature sets include support for the second-generation Channel Interface Processor (CIP2). All other feature sets that do not include "CIP2" in their names (refer to Table 3 and Table 4 ) support the original CIP card. The new feature sets on both platforms are

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

The CIP2 card includes the following improvements over the original CIP:

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

The Enterprise/CIP2 image or Enterprise/APPN/CIP2 image is required if you will be using the CIP2 card.


Note      Second-generation Channel Interface Processor (CIP2) microcode was introduced in Release 11.0(10).


New Features in Release 11.0(9)

No new features were added in Release 11.0(9).

New Features in Release 11.0(8)

The following enhancements were added to Release 11.0(8):

New Feature Sets for Cisco 1005

Cisco IOS Release 11.0(8) supports three new Cisco 1005 feature sets:

Refer to Table 9 for a list of features included in each of these sets.

UDP Turbo Flooding for Cisco 7500

User Datagram Protocol (UDP) datagram "turbo" flooding can be used on RSP systems (Cisco 7500 series and RSP7000). Previously, this feature was only supported on Cisco 7000 series routers.

New Features in Release 11.0(7)

The following enhancement was added to Release 11.0(7):

Support for the Cisco 4700-M Router

Release 11.0 now includes support for the Cisco 4700-M router. You can run Release 11.0(7) and later 11.0 releases on the Cisco 4700-M router.

New Features in Release 11.0(6)


Note      Cisco IOS Release 11.0(6) consists of software feature-set images for the Cisco 1003, Cisco 1004, and Cisco 1005 platforms only. All feature-set images for these routers are available. A complete set of images for all platforms supported by Release 11.0 is available in Cisco IOS Release 11.0(7) and later.


The following enhancements were added to Release 11.0(6):

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

A new Cisco-proprietary MIB for integrated CSU/DSU is available in Release 11.0(6) 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 RSP7000

The RSP7000 provides an upgrade in the Cisco 7000 series routers to an integrated Route Switch Processor (RSP), which was previously only available with Cisco 7500 series routers. RSP combines the switched routing and high-speed switching functions of the separate Route Processor (RP) and Switch Processor (SP), making obsolete the need for two separate processor units.

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.

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 BRI (ISDN) interface. 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 11.0(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:

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

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. number is the number of the port you want to use for ClickStart.

New Features in Release 11.0(5)

The following enhancements were added to Release 11.0(5):

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 11.0(5). ATM on the Cisco 4500 and Cisco 4700 routers is configured differently from that on the Cisco 7000 routers. Refer to the Router Products Configuration Guide for configuration information.

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

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 new Cisco devices.

The interfaces available in each model are shown as follows:

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.

Support for the Cisco 2524 and Cisco 2525

The Cisco 2524 and Cisco 2525 routers eliminate the need for a separate terminal adapter on the ISDN line, or separate channel service unit/data service units (CSU/DSUs) on the 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 2423 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.


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.

Leased Line via ISDN BRI

An ISDN Basic Rate Interface (BRI) can be used as an alternate method of accessing leased lines provided by digital communication service providers. The interface can provide any combination of one 16K (D channel) or two 64K (B channel) leased lines. No signaling or call setup is required.

In some locations, data communications service providers offer leased-line service over the ISDN physical connection. With this service, there is no call setup or teardown required. Data is placed on the ISDN interface in much the same way a leased line connected to a serial port is used.

The leased-line interface supports all commands that a normal serial leased-line interface supports, with the exception of the commands affecting the physical layer. To use this feature, your Cisco router must contain a minimum of one BRI. The command isdn leased-line is added.

New Features in Release 11.0(4)

The following enhancements were added to Release 11.0(4):

Support for the 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.

New Feature Sets for Cisco 1003 and Cisco 1004 ISDN Routers

Two new feature sets are available:

Payload Compression for Frame Relay

This feature allows payload compression of data within Frame Relay packets. Compression is performed on a packet-by-packet basis, yielding a compression ratio of approximately 1.5 to 1, depending on the packet and data characteristics. The command frame-relay payload-compress packet-by-packet is added.

Standard Serial Interface Processor and Service Provider MultiChannel Interface Processor on the Cisco 7000 Series

The Cisco 7000 series now supports the Standard Serial Interface Processor (SSIP) and Service Provider MultiChannel Interface Processor (SMIP).

New Features in Release 11.0(3)

The following enhancements were added to Release 11.0(3):

Support for the Channel Interface Processor (CIP) on the Cisco 7500 Series

Support for IBM channel attach is provided on the Cisco 7500 series routers by the Cisco Channel Interface Processor (CIP) and an appropriate interface adapter card. With a CIP and the ESCON Channel Adapter (ECA) or bus-and-tag Parallel Channel Adapter (PCA), a Cisco 7500 series router can be directly connected to a mainframe. This direct connection replaces the function of an IBM 3172 interconnect controller with no loss in LAN-to-channel connectivity, thus enabling mainframe application and peripheral access from LAN-based workstations. Cisco IOS software supports TCP/IP mainframe protocol environments for the IBM MVS and VM operating systems, including the TCP/IP-based applications Telnet, FTP, SMTP, and NFS.

Dynamic Address Mapping for IPX over SMDS

The new smds glean command dynamically creates SMDS address to higher-level protocol address mappings from incoming packets. Therefore the need for static map configuration for the IPX protocol is optional rather than mandatory. However, static map configurations will override the dynamic maps configurations.

IP Address Pooling Changes

IP address pooling provides a pool of IP addresses from which an incoming interface can provide an IP address to a remote node through the IP Control Protocol (IPCP) address negotiation process. In Cisco IOS Release 11.0(3), the IP address pooling feature is enhanced to allow configuration of a global default address pooling mechanism, a per-interface configuration of the mechanism to use, and a per-interface configuration of a specific address or pool name to use. Cisco IOS Release 11.0(3) also enhances the flexibility of configuration by allowing multiple types of pooling to be active simultaneously.

ISDN B-Channel Setup and Teardown

Previously, an idle timeout was used to determine when to tear down (drop) an ISDN B channel. If there was no traffic on a B channel for the idle timeout period, the B channel would be dropped. Various methods, including "round robin" or "shortest queue" methods, were used to determine when to set up a B channel (depending on the hardware platform in use).

ISDN B channels are now set up or torn down based on the amount of aggregate traffic loading across all active B channels. A new B channel will be set up if the aggregate load exceeds a maximum value for a timeout period. A B channel will be disconnected if the aggregate load drops below a minimum value for a timeout period.

The maximum load value is equal to 64K*N*(load-threshold/255), and the minimum load value is equal to 64K*(N-1)*(load-threshold/255), where N is the number of currently open B channels, and load-threshold is a configurable value.

Multilink PPP

Cisco IOS Release 11.0(3) supports Multilink Point-to-Point Protocol over single or multiple ISDN interfaces. This feature provides load balancing functionality over multiple WAN links, while also providing multivendor interoperability, packet fragmentation and proper sequencing, and load calculation on both inbound and outbound traffic. This feature allows users to specify a load threshold for a link to a given IP address. When the traffic load surpasses that threshold, additional point-to-point links come up. Packets are then sent over all of the links. Cisco's implementation of Multilink PPP supports the fragmentation and packet sequencing specifications in RFC 1717.

Multivendor Flash SIMM Support

With Release 11.0(3), you can use Flash SIMMs from multiple vendors, as long as the total size of each SIMM is equal (if both slots are used, where available), and the SIMMs are installed in one of the combinations shown in Table 11 (for Cisco 2500 series, Cisco 4000-M, Cisco 4500, and Cisco 4700 platforms) or Table 12 (for the AccessPro PC card and Cisco 2517 router).

Multivendor Flash support is restricted to platforms that use Rxboot Version 10.2(7a) or later, and Cisco IOS Release 10.2(8), 10.3(6), or 11.0(3) or later. Currently, the Cisco 3000 series and Cisco 4000 series platforms do not support the multivendor Flash feature.

Cisco 2500 series routers (non AccessPro) and the Cisco 4500 and Cisco 4700 routers have two slots for Flash SIMMs. Table 11 provides the supported SIMM configurations.

PPP Callback

Cisco IOS Release 11.0(3) supports PPP callback, which provides a client-server relationship between the end points of a point-to-point serial connection. PPP callback allows a router to request that a dial-up peer router call back. The callback feature can be used to control access and toll costs between the routers. This feature is a partial implementation of the PPP Callback specifications in RFC 1570.

SSE Switching of Input Access Lists

Beginning with Cisco IOS Release 11.0(3), input access lists are supported under silicon switching.

Support for the Cisco 1004 ISDN Router

The Cisco 1004 is an ISDN router similar to the Cisco 1003. The Cisco 1003 has a B interface that is connected to an NT1, which is connected to the phone company's ISDN line. The Cisco 1004 has a built-in NT1. The Cisco 1004 has one console port, one Ethernet 10BaseT port, one Basic Rate Interface (BRI) port, and one PCMCIA card slot. The BRI port is the interface between the NT1 and the phone company's ISDN line.

New Features in Release 11.0(2)

The following enhancements were added to Release 11.0(2):

Support for the Fast Ethernet Interface Processor on the Cisco 7000 Series and Cisco 7500 Series

The Cisco 7000 series and the Cisco 7500 series routers support the Fast Ethernet Interface Processor (FEIP) card, which allows communications speeds of 100 megabits per second (Mbps).

Support for the Cisco 1003 ISDN Router

Release 11.0 now includes support for the Cisco 1003 ISDN router.

QLLC and Bisync

The QLLC and Bisync features are included to the following feature sets for the Cisco 2500 series and Cisco 4000 series routers:

The Bisync feature is included in the following feature set for the Cisco 2500 series routers:

New Features in Release 11.0(1)

This section describes new features and enhancements in the initial Cisco IOS Release 11.0 of the router products software.

General Features

This section describes general features that are new in the initial release of Cisco IOS Release 11.0.

Conversations are sorted into two categories—those that are attempting to use a lot of bandwidth with respect to the interface capacity (for example, FTP) and those that need less (for example, interactive traffic). For streams that use less bandwidth, the queuing algorithm always attempts to provide access with little or no queuing and shares the remaining bandwidth between the other conversations.

Backbone Protocol Routing Features

This section describes the backbone protocol routing features that are new in the initial release of Cisco IOS Release 11.0.

TCP/IP Features

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

Transparent Bridging Features

The following feature has been added to Cisco's transparent bridging software:


Note      CRB is not a source-route bridging (SRB) feature.


Desktop Protocol Features

This section describes the desktop protocol features that are new in the initial release of Cisco IOS Release 11.0.

AppleTalk Features

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

Benefits of using NBP filters include:

Banyan VINES Features

The following feature has been added to Cisco's Banyan VINES software:

Novell Features

The following feature has been added to Cisco's Novell software:

Wide-Area Networking Features

This section describes the wide-area networking features that are new in the initial release of Cisco IOS Release 11.0.

ISDN/DDR Enhancements

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

X.25 Enhancements

The following feature has been added to Cisco's X.25 software:

Frame Relay

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

ATM Enhancements

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

Cisco's implementation of the ATM ARP server functionality provides a robust environment in which network changes can be made more easily and more quickly than in a pure ATM environment. Cisco's ATM ARP client works with any ARP server that is fully compliant with RFC 1577.

Core Enhancements

The following feature has been added to the Cisco 7000 router:

IBM Functionality Features

This section describes the IBM networks software features and support that are new in the initial release of Cisco IOS Release 11.0.

New Features

The following new IBM software features are available:

DSPU concentration provides scalability benefits in integrated SNA and multiprotocol networks, reduces mainframe configuration requirements, limits WAN overhead, and speeds recovery of SNA sessions following network failures or restarts. In many environments, DSPU concentration eliminates the need for SNA gateways. Support for Ethernet and SDLC connections provides additional flexibility in connecting DSPUs and upstream mainframes to Cisco routers offering DSPU concentration.

With the addition of TCP/IP offload, the CIP now offers two methods for communicating with mainframes running a TCP/IP stack: traditional gateway connections, which offer the highest level of performance, or offload, which offers high performance as well as mainframe cycle savings. Typically, 30 percent of the mainframe cycles that were dedicated to full TCP/IP processing can be saved by implementing TCP/IP offload.


Note      For the TCP/IP offload feature and the SNA support over CIP feature, contact your local sales representative for an update on the prerequisite microcode. Target microcode availability is anticipated in early October 1995 in Cisco IOS Release 11.0(2).


New MIB Support

The following new MIBs are available:

Access Server Features Supported on the Router

This section describes the access server features that are new in the initial release of Cisco IOS Release 11.0.

Important Notes

This section describes warnings and cautions about using the Cisco IOS Release 11.0 software. This section discusses these topics:

BSC and SDLC Commands in Releases 11.0(5) and 11.0(6)

In Release 11.0(5), the bsc fdx and sdlc hdx commands were deprecated and replaced by new versions of the media-type command. Also, the sdlc cts-delay and sdlc rts-timeout commands were deprecated and replaced by the half-duplex timer command.

In Release 11.0(6), the half-duplex and full-duplex keywords of the media-type commands were removed and replaced by the half-duplex and full-duplex commands, respectively.

All of the deprecated commands continue to be supported in Release 11.0(6) and later.

X.25 Problem in 11.0(2)

Cisco IOS Release 11.0(2) contains a software defect, affecting all platforms, that involves an unexpected router reload when X.25 is configured. This defect, CSCdi40956, is not present in Release 11.0(1) and is fixed by Release 11.0(3).

Upgrading to a New Software Release

If you are upgrading to Cisco IOS Release 11.0 from an earlier Cisco IOS software release, you should save your current configuration file before installing Release 11.0 software on your router.

Emulated LAN Interoperability

Cisco IOS Release 11.0(6), Release 11.1(2), and Catalyst 5000 ATM software Release 2.1 and later contain a fix for an emulated LAN defect. This fix is incompatible with earlier releases of Cisco IOS Release 11.0, Release 11.1, and Catalyst 5000 ATM software Release 1.1.

If you use emulated LAN bridging features in your network, and you upgrade any device to Cisco IOS Release 11.0(6), Release 11.1(2), or Catalyst 5000 ATM software Release 2.1 or later, you must upgrade all devices in the emulated LAN that run Cisco IOS software to a release level that contains the emulated LAN fix. Failure to upgrade all devices in a particular emulated LAN will result in interoperability problems between Cisco devices.

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.

Payload Compression for Frame Relay Support

The payload compression for the Frame Relay feature is not supported in Cisco IOS Release 11.0(1), Release 11.0(2), or Release 11.0(3). This feature is supported in Release 11.0(4).

Multiring FDDI Support

Multiring FDDI features are not supported in Cisco IOS Release 11.0(1), Release 11.0(2), Release 11.0(3), Release 11.0(4), Release 11.0(5), Release 11.0(6), or Release 11.0(7).

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 AGS+ 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.


Fast Switching of SRB over FDDI on Cisco 4000 Series

Earlier Cisco IOS Release 11.0 release notes inadvertently indicated that fast switching of SRB over FDDI was supported on the Cisco 4000 series. SRB over FDDI for the Cisco 4000 series routers is not supported in any release of Cisco IOS Release 11.0.

Cisco 1000 Series Support

The Cisco 1000 series, including the Cisco 1003 ISDN router is not supported in Cisco IOS Release 11.0(1). The Cisco 1003 router is supported in Release 11.0(2). The Cisco 1004 router is supported in Release 11.0(3). The Cisco 1005 is supported in Release 11.0(4). Note that the size of the Cisco 1003 and Cisco 1004 feature set images released in Release 11.0(3) prevent those routers from running if large routing tables are present. Those images are now obsolete, and new images are available in Release 11.0(4) and later.

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 source-route bridging (SRB) protocols such as SNA and NetBIOS, and 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).

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 11.0(10a) Fixes Caveat CSCdi66673

After the release of Cisco IOS Release 11.0(10), a caveat was discovered within the rsp- Cisco IOS 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 11.0(10a).

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 11.0(10a) and all subsequent releases of Cisco IOS software, including Release 11.0(11), include the fix for this caveat.

Release 11.0(12a) Fixes Caveat CSCdi71609

After the release of Cisco IOS Release 11.0(12), a caveat was discovered within the rsp- Cisco IOS 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 11.0(12a). Release 11.0(12a) includes 11.0(12) images plus the rebuilt rsp- images.

This defect is bug CSCdi71609 and is described as follows:

A serious bug has been found within various Cisco IOS software releases. In extremely rare conditions, a failure condition can occur when Backing-Store or Fair Queuing are enabled. To avoid these problems, the rsp- Cisco IOS images in affected releases are no longer available.

This problem can be avoided by disabling both Backing-Store and Fair Queuing on existing Cisco IOS software releases with rsp- images.

Release 11.0(12a) and all subsequent releases of Cisco IOS software, including Release 11.0(13), include the fix for this caveat.

Release 11.0(13a) Fixes Caveat CSCdi92818

Cisco IOS software release 11.0(13) was deferred due to a severe defect in source-route bridging protocol when used on a Route Switch Processor (RSP)-based platform, including the Cisco 7500 series and RSP7000 routers.

This defect is bug CSCdi92818 and is described as follows:

CSCdi92818 affects any RSP router running Cisco IOS Software Interim 11.0(12.3) through 11.0(13.3) with a CIP and/or a TRIP, and a FDDI. If the CIP or the TRIP are passing RIF data, the FDDI will stop passing traffic. The FDDI will not acknowledge incoming traffic on FDDI interfaces if SRB is in use anywhere in the router. There is no known workaround. SRB needs to be turned off in these configurations.

If you are not running source-route bridging in your network, this defect does not apply to you. If you are running source-route bridging in your network, certain interface types on an RSP-based platform may be specifically affected.

If you believe your network may be impacted by this defect, you can obtain Cisco IOS Release 11.0(13a) from the Cisco Connection Online Software Upgrade Library.

Release 11.0(13a) and all subsequent releases of Cisco IOS software, including Release 11.0(14), include the fix for this caveat.

Release 11.0(14a) Fixes Caveat CSCdj05366

Cisco IOS software release 11.0(14) was deferred due to a severe defect.

This defect is bug CSCdj05366 and is described as follows:

When establishing a second telnet session to a router, vty does not echo characters; the first established session works correctly.

If you believe your network may be impacted by this defect, you can obtain Cisco IOS Release 11.0(14a) from the Cisco Connection Online Software Upgrade Library.

Release 11.0(14a) and all subsequent releases of Cisco IOS software, including Release 11.0(15), include the fix for this caveat.

Caveats for Release 11.0(1) through 11.0(22a)

Cisco IOS Release 11.0(22a) is a rebuild release for Cisco IOS Release 11.0. The caveats in this section are resolved in Cisco IOS Release 11.0(22a) but may be open in previous Cisco IOS releases.

The vulnerability is only present in certain combinations of IOS releases on Cisco routers and switches. ILMI is a necessary component for ATM, and the vulnerability is present in every IOS release that contains the supporting software for ATM and ILMI without regard to the actual presence of an ATM interface or the physical ability of the device to support an ATM connection.

To remove this vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is documented in DDTS record CSCdp11863.

In lieu of a software upgrade, a workaround can be applied to certain IOS releases by disabling the ILMI community or "*ilmi" view and applying an access list to prevent unauthorized access to SNMP. Any affected system, regardless of software release, may be protected by filtering SNMP traffic at a network perimeter or on individual devices.

This notice will be posted at http://www.cisco.com/warp/public/707/ios-snmp-ilmi-vuln-pub.shtml. [CSCdp11863]

This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.

To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.

Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.

This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml. [CSCds04747]

Caveats for Release 11.0(1) through 11.0(22)

This section describes possibly unexpected behavior by Release 11.0(22). Unless otherwise noted, these caveats apply to all 11.0 releases up to and including 11.0(22).

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.

Basic System Services

The only known workaround is to completely unconfigure the old card before replacing it with the new card. 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 card. Once the information that is displayed by the show commands is self-consistent, the newly inserted card behaves normally. [CSCdi49800]

Interfaces and Bridging

IP Routing Protocols

(1) An OSPF external LSA contains a forwarding address that OSPF has no route for, and

(2) A static route to the forwarding address is configured, and it points out an interface that OSPF is running on.

To work around this problem, either remove the static route, or prevent the unreachable forwarding address from being included in the external LSA by making sure that any ASBRs redistributed between different OSPF domains has the fix for CSCdi63983. [CSCdk52593]

ISO CLNS

Wide-Area Networking

The problem can also occur in routers. The shut and no shut commands need to be issued on the ATM interface in order to reset the sequence counters. This reset may also be used to free buffer resources in a system that has encountered the SSCOP wrap but not yet crashed. [CSCdj45157]

Miscellaneous

Caveats for Release 11.0(1) through 11.0(21)

This section describes possibly unexpected behavior by Release 11.0(21). Unless otherwise noted, these caveats apply to all 11.0 releases up to and including 11.0(21).

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 11.0(22).

IP Routing Protocols

Other platforms, including the Cisco 3600, 4500, 4700, 5300, 7000 (RSP), 7200, 7500, 8500, and RSM series routers may display the record as a spurious memory access. The Enhanced IGRP event log is invalid on all platforms.

The workaround to this problem is to not display the event log or enable Enhanced IGRP event logging. Additionally, the event log can be disabled by issuing the following commands (as appropriate) from configuration mode on the router:

IP:

router eigrp as eigrp event-log-size 0

IPX:

ipx router eigrp as event-log-size 0

Appletalk:

appletalk eigrp event-log-size 0

%APPN-7-MSALERT: Alert LU62004 issued with sense code 0x812000D by XXXSMPUN

This sense code indicates that APPN is running out of buffers and therefore unable to allocate new sessions. One solution is not to reserve the unbind buffers in advance during the BIND time. [CSCdj87034]

Interfaces and Bridging

IP Routing Protocols

The loss of the route is due to sporadic line congestion (packet drops) and/or SIA events 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 known workaround is to issue the clear ip route * command. [CSCdj73617]

The workaround is to not reconfigure virtual rings or remote peers while executing a show source command. [CSCdj49973]

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]

There is no known workaround. [CSCdj25859]

There is no alternative workaround when this happens. The router is forced to restart by the system watchdog process (software-forced reload event).

This problem occurs when two links are active to the same node and 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]

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.

It is possible to revert to the previous operation using the hidden interface command ppp ipcp accept-address. When enabled, the peer IP address will be accepted but is still subject to AAA verification. It will have precedence over any local address pool, however. [CSCdj04128]

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]

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]

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]

CyBus errors similar to the above errors have two known causes.

The workaround on dual-CyBus platforms is to move all the HIPs onto a CyBus that is not oversubscribed.

The errors can also 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]

Basic System Services

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

A 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, which is used to do bridge filtering on the card. When encapsulated bridging is used, the main processor has to 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 to accomplish bridge filtering. [CSCdi46862]

EXEC and Configuration Parser

IBM Connectivity

A workaround is to configure the required filter at the originating router, either at the interface or DLSw level. (This is a large administrative task in large networks.) [CSCdi87600]

Interfaces and Bridging

If this incoherency occurs but does not cause a router crash, it might instead cause ciscoBus switching to be automatically disabled, and the interface would resort to fast switching or SSE switching (if SSE switching was configured). [CSCdi43526]

CBUS-3-INTERR: Interface 6, Error (8011) 

This problem occurs because the bridging code sees "aaaa" and assumes the packet is SNAP encapsulated. Because SNAP encapsulated packets have a minimum length of 21, the bridging code subtracts 21 from the original length of the packet (20) when queuing it on the outbound interface. This results in a packet length of -1 or 65535 bytes. This causes the SP to become confused and write over low core, causing the 8011 error. [CSCdi65953]

Basic System Services

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

[CSCdi70032]

For Release 11.0, this problem has been fixed in maintenance releases 11.0(12a), 11.0(13) and later 11.0 releases.

To avoid this problem, Cisco highly recommends that you upgrade all Release 11.0 RSP-based systems to Cisco IOS Release 11.0(12a), 11.0(13), or a later 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 11.0(9.2). 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 Release 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. [CSCdi71609]

This problem is caused by the way small buffers handle Spanning Tree BPDUs. When a BPDU comes in, a small buffer is used. If the interface goes down at the same time the BPDU comes in, the small buffer is not released even though it should be. [CSCdi72783]

Cisco IOS Release 11.0(10a)

The Cisco IOS Release 11.0(10) rsp- images were rebuilt to include a single defect fix, and were renumbered to 11.0(10a). The defect is bug CSCdi66673 and is described as follows:

When Ethernet runt packets are received by Cisco 7500 series Router Switch 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:

IP Routing Protocols

It is also possible for a race condition to occur, where the majornet route is lost, even after it has been received and installed into the routing table.

The workaround for this problem is a floating static route for the majornet matching the PPP-created host route using a majornet mask pointing to the PPP-created host route. For example, if the host route is 192.1.1.1, then using the command ip route 192.1.1.0 255.255.255. 0 192.1.1.1 250 should solve the problem. [CSCdi65258]

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

A temporary workaround is configuring the interface level command: hold-queue 750 in until you are able to reload the router. Remove this configuration after upgrading the software. [CSCdi61629]

These messages most often appear in Cisco 4000 series routers when the routers are being reloaded. The workaround is to put the ATM interfaces in the shutdown state before reloading. [CSCdi62194]

The work around is to define static peers.

Note: CSCdi61278 is a follow-on fix to this problem. [CSCdi58842]

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.

Note that this bug fix is comprehensive in that several issues regarding multicast explorers and inbound remote explorers have now been resolved. [CSCdi59090]

In addition to the hardware requirements, the fix for this bug that is in Release 11.0(6) 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.

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]

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

One workaround is to configure SNMP or syslog to a host on the remote side. An SNMP trap is required for snmp-server host x.y.z.w, or a console message to logging host, but will initiate a dialout. [CSCdi46312]

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 routers connected via ISDN. This assumes the other router or routers do not have BRIs connected to NET3 switches, as 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. [CSCdi46668]

This problem can be avoided if each PPP interface is configured correctly for a peer address, for address pooling, or with pooling explicitly disabled.

The commands to configure pooling (local or DHCP) are site-specific.

If a fixed peer address is acceptable, it can be set with the command peer default ip address a.b.c.d where a.b.c.d is the IP network address of the peer. Note that this command replaces the command async default ip address a.b.c.d for asynchronous interfaces, but applies to all PPP and SLIP interfaces including ISDN interfaces.

Pooling can be explicitly disabled on an interface by issuing the command no peer default ip address.

This command has no other effect and can be replaced later with an appropriate address pooling configuration. [CSCdi43677]

If an asynchronous interface has a configured pool name that needs to be changed, the workaround is to first enter any other variation of the command. For example, peer default ip address pool or no peer default ip address. You can then enter the peer default ip address poolname command.

This sequence should only be used when the pool name of an asynchronous interface needs to be changed. You do not need to do this if a specific peer IP address needs to be configured, if pooling needs to be disabled completely, or if the default selection needs to be set. [CSCdi39470]

Microcode Software

Table 13 and Table 14 list the minimum microcode versions for the AGS+, MGS, and CGS platforms, Table 15 lists the current microcode versions for the Cisco 7000 series, and Table 16 lists the current microcode versions for the RSP-based systems (Cisco 7500 series and 7000RSP). Note that for the Cisco 7000 series, microcode software images are bundled with the system software image. Bundling eliminates the need to store separate microcode images. When the router starts up, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards.
