Cisco IOS Release 11.1 CA supports the following platforms:
- Cisco 7500 series routers
- Cisco 7200 series routers
- Cisco 7000 series routers with RSP7000 and RSP7000CI
Refer to the Release Notes for Cisco IOS Release 11.1 publication for a summary of the LAN interfaces supported on each platform and the WAN data rates and interfaces supported on each platform.
The following feature sets are available in Release 11.1 CA for the Cisco 7000 series routers with RSP7000 and RSP7000CI, Cisco 7200 series routers, and Cisco 7500 series routers. Refer to Release Notes for Cisco IOS Release 11.1 for a complete list of the features provided in these sets.
For the Cisco 7500 series routers and Cisco 7000 series routers with RSP7000 and RSP7000CI:
- Enterprise (rsp-j-mz image)
- Enterprise/APPN (rsp-aj-mz image)
- Enterprise/VIP (rsp-jv-mz image)
- Enterprise/APPN/VIP (rsp-ajv-mz image)

The memory requirements for feature sets available in Release 11.1 CA are the same as those listed in the "Memory Requirements" section in the Release Notes for Cisco IOS Release 11.1 publication except for the following:
- For Cisco IOS Release 11.1(9)CA or later, the Cisco 7200 series requires 32 MB of main memory for all feature sets. The boot image used by the Cisco 7200 series router has been changed to a self-decompressing compressed image because the uncompressed boot image exceeds 4 MB.
- For port adapter hardware and memory configuration guidelines for the Cisco 7200 series routers, refer to the document Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.
- The Cisco 7500 series requires a 16- or 20-MB Flash memory card to support the Enterprise/APPN/VIP feature set and the CIP microcode.
The microcode software version information for Release 11.1 CA is the same as the information listed in the "Microcode Software" section of the Release Notes for Cisco IOS Release 11.1 publication with the following additions:
- The next-generation Route Switch Processor (RSP4) uses the same microcode software versions listed for the RSP in the Release Notes for Cisco IOS Release 11.1 publication.
- The second-generation Fast Ethernet Interface Processors (FEIP2-2TX and FEIP2-2FX) use the same microcode software version listed for the VIP2 in the Release Notes for Cisco IOS Release 11.1 publication.
The following sections list the new features that are available in each release of Cisco IOS Release 11.1 CA. Features are described in detail in the documentation that accompanies the hardware. The feature modules contain a brief description of the feature and new or modified Cisco IOS commands supported by the feature. For easy online access, these features are linked to the applicable Cisco IOS feature module (if one exists). Click on the link to open the feature module.
The following new features have been added to Release 11.1(17)CA:
- NetFlow Switching Enhancements --The new ip flow-cache active-timeout configuration command lets you specify the timeout period for the NetFlow cache.
- RJ-45 Interface Support--Cisco 7200 series routers support a new I/O controller with an RJ-45 interface. The optional Fast Ethernet port is configurable for use at 100 Mbps full-duplex or half-duplex (half duplex is the default). The Fast Ethernet port is equipped with either a single MII receptacle or an MII receptacle and an RJ-45 receptacle.
- To support this new feature, the media-type interface command has been modified. The media-type interface command now supports two options:
- 100basex--Specifies an RJ-45 100BaseX physical connection
- mii--Specifies a media-independent interface
Note When using the I/O controller that is equipped with an MII receptacle and an RJ-45 receptacle, only one receptacle can be configured for use at a time.
The following new features have been added to Release 11.1(16)CA:
- Channelized T3 Dual-Wide Port Adapter --The channelized T3 dual-wide port adapter (PA-CT3/4T1) is available on Cisco 7200 series routers.
- VIP Enhancements --New privileged EXEC commands provide more information about the Versatile Interface Processor (VIP). The command show controllers logging displays logging information about a VIP. The command show controllers tech-support displays general information about a VIP when reporting a problem. The command show controllers align shows NULL pointer dereferences and misaligned accesses for a VIP.
- POS Command Enhancement --The new interface command pos scramble-atm enables SONET payload scrambling on a POS interface. SONET payload scrambling applies a self-synchronous scrambler (x^43+1) to the Synchronous Payload Envelope (SPE) of the interface to ensure sufficient bit transition density.
- Distributed Switching for LANE--In LAN Emulation (LANE) networks, distributed switching for LANE is a new Cisco 7500 series feature that allows a LAN Emulation Client (LEC) to be distributed from the RSP to one or more VIP2 interfaces. In doing so, the VIP2 distributed switching capability can now provide switching between each emulated LAN connected to each VIP2 independently. This ability provides increased aggregate IP switching performance across the 7500 architecture for LANE networks versus centralized RSP switching. The inter-ELAN switching performance provided by the VIP2 modules is additive across the 7500 series routers and increases with each new VIP2/ATM port adapter. This ability also minimizes the utilization of the RSP--freeing the RSP for other functions including low-level routing and routing updates.
- The other components of LANE, such as LAN Emulation Servers (LES), broadcast and unknown server (BUS), and LAN Emulation Configuration Servers (LECS), are functions used primarily during network initialization for address look-ups. These functions are not in the data flow, and distributing these functions do not provide any performance gain. Therefore, the LES, BUS, and LECS functions continue to reside on the RSP with this feature.
- Distributed switching for LANE for the Cisco 7500 series is completely ATM Forum compliant. It is intended for any Enterprise or ISP ATM applications where multiple VIP2/ATM port adapter combinations are installed in the same 7500 series router, or for any ATM applications where the performance can be optimized by dedicating the RSP to other routing functions.
- This capability only supports the IP protocol for Ethernet LANE in a distributed manner. Token Ring LANE is not supported via distributed switching; however, it is supported within the RSP.
- LANE Optimum Switching Enhancement--Optimum switching is now supported for LANE traffic on RSP.
The following new features have been added to Release 11.1(15)CA:
- PA-T3 and PA-2T3 Serial Port Adapter --The PA-T3 and PA-2T3 serial port adapters are available on Cisco 7200 series routers, on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
- VIP2-50 --The VIP2-50 is available on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). Although the VIP2-50 is being announced with Release 11.1(15)CA, it is also supported in Release 11.1(14)CA1.
- High-Speed Serial Interface Port Adapters --The PA-2H Revision B port adapter is available on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). This port adapter was revised to improve performance.
- Channelized T3 Interface Processor Feature Enhancements --The Channelized T3 Interface Processor (CT3IP) available on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) now supports the following types of remote line Facility Data Link (FDL) loopback:
- FDL ANSI loopback per ANSI T1.403
- FDL Bellcore loopback per TR-TSY-000312
- NetFlow Switching Enhancements --The NetFlow switching commands have been modified to provide added functionality. The ip flow-export destination, ip flow-export source, and ip flow-export version commands replace the ip flow-export command.
The following new features have been added to Release 11.1(14)CA:
- Fast EtherChannel --The Fast EtherChannel feature allows multiple Fast Ethernet point-to-point links to be bundled into one logical link to provide bidirectional bandwidth of up to 800 Mbps. Fast EtherChannel can be configured between Cisco 7500 series routers and Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) or between a Cisco 7500 series router or a Cisco 7000 series router with the RSP7000 and RSP700CI and a Catalyst 5000 switch.
- PA-A2 ATM-CES Port Adapter Enhancements --The ATM-CES port adapters (PA-A2-4T1C-OC3SM, PA-A2-4T1C-T3ATM, PA-A2-4E1XC- OC3SM, PA-A2-4E1XC-E3ATM, PA-A2-4E1YC-OC3SM, and PA-A2-4E1YC-E3ATM) available on Cisco 7200 series routers now support the following new features:
- Available Bit Rate (ABR)--The ABR service category is specified in the ATM Forum Traffic Management Specification Version 4.0.
- Virtual Path Shaping--A virtual path (VP) is a logical association or bundle of virtual circuits (VCs).
- In addition, all traffic shaping features available with the atm pvc interface command (peak average burst) are supported, and you can now configure the number of transmit channels for the interface with the atm tx-channels interface configuration command.
- Web Cache Control Protocol --The Web Cache Control Protocol feature transparently redirects HTTP requests from the intended server to a Cisco Cache Engine. When the Cisco Cache Engine receives the request, it attempts to service the request from its own cache. If the requested information is not present, the Cisco Cache Engine then makes a request to the web server to get the required information. After receiving the required information from the web server, the Cisco Cache Engine passes the information back to the client and possibly caches it to fill future requests.
The following new features have been added to Release 11.1(13)CA1:
- PA-E3 and PA-2E3 Serial Port Adapters --The PA-E3 and PA-2E3 serial port adapters are available on Cisco 7200 series routers, on Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).
- NPE-200 Network Processing Engine for Cisco 7200 Series Routers --The NPE-200 for Cisco 7200 series routers is now available. The network processing engine maintains and executes the system management functions for Cisco 7200 series routers. The network processing engine also shares the system memory and environmental monitoring function with the I/O controller. The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of 200 MHz, 4 MB of SRAM, and erasable programmable read-only memory (EPROM) for storing sufficient code for booting the Cisco IOS software.
- NetFlow Switching Enhancements --The NetFlow switching commands have been modified to provide added functionality. The NetFlow switching enhancements are also available in Cisco IOS Release 11.1(11)CA or later. Netflow switching is a high-performance, network-layer switching path that captures as part of its switching function a rich set of traffic statistics. These traffic statistics include user, protocol, port, and type of service information that can be used for a wide variety of purposes such as network analysis and planning, accounting, and billing.

This section contains important information about the Cisco IOS Release 11.1 CA software. The following information describes the changes in release number for Release 11.1 CA:
- This release note lists the Cisco IOS release in which a port adapter or interface processor was first announced. However, the minimum or recommended release of Cisco IOS software required for a port adapter or interface processor might be a later release. The recommended release changes periodically and might not be the same release in which the port adapter or interface processor was announced. In some cases the change is to support new features and in others to correct caveats.
- The hardware documentation that ships with the port adapter or interface processor lists the minimum release of Cisco IOS required to support the port adapter, which might not be the Cisco IOS you currently have running on your router. The hardware documentation is updated as often as possible to note changes in the Cisco IOS requirements. Manufacturing always ships the current minimum Cisco IOS release with the port adapter or interface processor. The latest Cisco IOS software is available on CCO.
- Release 11.1(14)CA1 replaces 11.1(14)CA. Release 11.1(14)CA1 corrects the following caveats:
- CSCdj21539--Routers running remote source-route bridging (RSRB) from a Cisco 7200 or Cisco 7500 series router with a PA-4R Token Ring insert an invalid Token Ring frame check sequence (FCS) in frames sent to remote peers. The invalid FCS will cause data frames to be dropped on some remote peer routers. Affected remote peer routers are Cisco 2500 series, Cisco 4000 series, Cisco 4500 series, and Cisco 4700 series routers running Cisco IOS Release 10.2 or earlier. Other router models and routers running Cisco IOS Release 10.3 or later are not affected.
- CSCdj42431--A Cisco 7206 router restarts with CLSIMsgCreateFromPak after a crashdump on the show stack output.
- CSCdj44697--On a Cisco 7200 router under certain conditions, packets that saw an optimum cache miss and an input access list failure can cause another packet to be corrupted.
- CSCdj42984--When source- route bridging (SRB) is configured between two or more directly attached Token Ring interfaces in a router, Cisco IOS software re-calculates and appends a new FCS (CRC) to the end of the old FCS. This results in four extra bytes of "data" being added to the frame's field.
- For additional information, refer to the Field Notice: Cisco C7200 IOS ED 11.1(14)CA Source Route Bridging publication on CCO at the following location:
- http://www.cisco.com/warp/customer/770/
- Release 11.1(13a)CA1 replaces 11.1(13)CA1. Release 11.1(13a)CA1 corrects the following caveat:
- CSCdj31496--Unpredictable failures in all routed protocols. Use the following workaround to temporarily clear related routing problems--for IP, use the clear ip route command and for all other protocols, use the shutdown command followed by the no shutdown command.
- For additional information, refer to the Field Notice: Cisco IOS Routed Protocol Defect publication on CCO at the following location:
- http://www.cisco.com/warp/customer/770/
- Release 11.1(13)CA1 replaces 11.1(13)CA. Release 11.1(13)CA1 corrects the following caveat:
- CSCdj23465--The output from the show stack command might display configuration or password information obtained from the console buffer.
- For additional information, refer to the Field Notice: Cisco IOS Release 11.1(13)CA publication on CCO at the following location:
- http://www.cisco.com/warp/customer/770/
- Release 11.1(12)CA1 replaces Release 11.1(12)CA. Release 11.1(12)CA1 corrects the following caveats:
- CSCdj23299--The CT3 reports massive overruns (up to 1100 per second) from the RSP side. However, we later discovered that the overruns were not "real" overruns, but actually ignores being counted erroneously as overruns.
- CSCdj24098--Under high traffic conditions the HSSI port adapter might handle the packets abnormally. We strongly encourage customers using HSSI port adapters on Cisco 7200 series routers to upgrade to an image containing the fix for this bug.
- CSCdi64972--If a router is running out of memory while running OSPF, OSPF does not check to see if one of its structures has been properly allocated. This might result in a SegV exception and cause the router to reload.
- CSCdj24890--The internal clock of ATM port adapter is not initialized properly. This defect causes the loopback ping to fail because neither end is providing clock.
- CSCdj18696--The IEEE spanning tree BPDUs are not recognized by a VIP2 with a PA-4R in Cisco IOS Release 11.1(10)CA or 11.1(11a).
- CSCdj04220--When the debug atm event command is enabled on an ATM port adapter, the driver generates a spurious memory access when it tries to fetch statistics for all VCs.
- CSCdj24569--The OutPkts and InBytes per VC statistics counter shown by the show atm vc command is incorrect.
- Release 11.1(11)CA1 replaces 11.1(11)CA. Release 11.1(11)CA1 corrects caveat CSCdj17858 for Cisco 7200 series images--when an INARP VC is configured on an ATM port adapter while the interface is in a shutdown state, after the interface is brought up the ATM port adapter might cause the router to reload the next time an INARP packet is received.
- To eliminate several problems associated with the VIP2, POSIP, and CT3IP products, we recommend you upgrade to Cisco Release 11.1(10)CA or later. For more information on these problems and for other recommended Cisco IOS software versions, refer to the Field Notice: VIP2 Cisco IOS Software Release Deferrals (Text Part Number 78-4499-01) posted on Cisco Connection Online (CCO) at the URL listed below. CCO is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.
- http://www.cisco.com/warp/customer/770
- Release 11.1(9)CA1 replaces Release 11.1(9)CA. Release 11.1(9)CA1 resolves caveat CSCdi89690--on PA-H and PA-2H HSSI port adapters, users might experience CRC, overrun, and underrun when a second HSSI port adapter in installed and running on the same VIP2. For information on this caveat, refer to the "Caveats for Release 11.1(9)CA1" section.
- Release 11.1(8)CA1 replaces Release 11.1(8)CA. Release 11.1(8)CA1 corrects MIP and POSIP microcode versions and corrects the ROM monitor version required for the RSP4.
Refer to the Release Notes for Cisco IOS Release 11.1 publication for a list of the caveats that apply to Release 11.1. The caveats that apply to Cisco IOS Release 11.1 apply to Release 11.1 CA.
Only serious caveats with release note attachments are described in these release notes. The complete caveats against Release 11.1 are available in the Cisco Documentation CD-ROM package. In the CD-ROM package, access the Cisco IOS 11.1 caveats in the Cisco IOS Release 11.1 database. If you have an account on Cisco Connection Online (CCO), you can view additional caveats using the bug search tools in the Bug Toolkit, such as the Bug Navigator.
This section describes possible unexpected behavior by Release 11.1(17)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(17)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
- After configuring source-route bridging on FDDI, many ignored packets are visible on a Cisco 7500 series router with the VIP2 FDDI port adapter. Older FIP cards do not show the ignored packets. The workaround is to use a FIP card. [CSCdj76260]
- A corrupt buffer header causes Cisco 7500 series routers to restart with a bus error. [CSCdj70296]
- A Cisco 7513 router has the following error message:
%RSP-2-QAERROR: reused or zero link error, write at addr 0160 (QA).
- This message means that an error occurred possibly due to the duplication of a packet pointer, which is an invalid state. [CSCdj41153]
- The console on Cisco 7500 HSA systems might become unresponsive with configurations larger than 128K and service compress-config. The console can lock up when a wr mem or copy running command is issued, and the configuration NVRAM can become corrupted and inaccessible. Other VTYS and packet forwarding and routing operations will continue unimpeded while the console or Telnet exec is nonresponsive.
- A workaround is to store the configuration in Flash memory. For example, use the following commands:
copy running slot0:config
boot config slot0:config
service compress
boot buffersize N
- where N is at least three times the configuration size in bytes. Then the wr mem command will work slowly. Expect 10 minutes elapsed time for each 128K block of configuration text.
- Use the following procedure to recover configuration NVRAM after NVRAM is corrupted:
Step 1 Send an RS232 break to the console of both master and slave.
Step 2 Use the ROM monitor command confreg on both master and slave to ignore system configuration.
Step 3 Use the ROM monitor command reset on master and slave and boot a slave-capable image.
Step 4 On the master console, copy the correct configuration file from Flash memory or tftp into the running configuration file.
Step 5 Turn off the 0x40 bit in the configuration register by using the sh ver Exec command and the config-register configuration command.
Step 6 Reload the master.
- [CSCdj63926]
- The ATM interface in the VIP crashed due to memory block corruption. There is no workaround. [CSCdj66230]
- After an interface is removed via online insertion and removal (OIR), the ARP entries associated with the interface might not be removed from the ARP table. A workaround for this problem is to issue the command clear arp after the OIR to remove the entries. [CSCdj67478]
- When channelized E1 port adapters and weighted fair queueing are configured, all interfaces of the channelized E1 port adapters have many drop packets. The workaround is to configure the following on each interface:
no fair-queue
no ip route-cache distributed
transmit-buffers backing-store
- [CSCdj69502]
- A Cisco 7000 Series Route Switch Processor (RSP7000) crashes when Frame Relay encapsulation is enabled on the High-Speed Serial Interface (HSSI). The workaround is to disable fast switching. [CSCdj70353]
- File transfers between a Token Ring host and another host connected via Fast EtherChannel can cause CPU utilization to increase between 80% to 100%. This increase occurs in both directions. The same operation works correctly when the Token Ring-attached host is accessed via another media type, such as ATM. The workaround is to disable Fast EtherChannel. [CSCdj71335]
- When configuring Fast EtherChannel on a Cisco 7500 series router, the following error messages are displayed:
%RSP-3-ERROR: CyBus1 error 10
%CBUS-3-CMDTIMEOUT: Cmd timed out
%RSP-3-RESTART: cbus complex
- [CSCdj74820]
- EIGRP might crash when receiving updates in a network that has a major topology change in conjunction with a large EIGRP topology database. There is no workaround. [CSCdj54728]
- The command distribute-list in does not filter static or summary (null0) routes. [CSCdj62406]
- We need better crash information to debug data/stack corruption crashes. The solution is to write crash information to default to bootflash:crashinfo in RSP and flash:crashinfo in RP. A series of test crash command selections are used to control and change the crashinfo collection mechanism. The crash information:
- Contains up to 32 KB in the RSP and up to 20 KB in the RP of errmsg log plus command history including configuration commands that the user enters or "copy"
- Contains up to 32 KB on the RSP and 20 KB on the RP for all the following information:
- Crash stack trace
- Crash context
- Stack dump at crash
- Dump memory for each register containing "valid" RAM address
- Add errmsg display on invalid length of bcopy
- Add two commands to "test crash"
- The sh stack command displays ("cat" as in UNIX) the bootflash:crashinfo file if there was a crash. The user can also use the command copy flash tftp to dump the ASCII file bootflash/flash:crashinfo to a server.
- The size is 16 KB of errmsg log and command history plus up to 16 KB of memory dump and other crash information. There is one 16 KB DRAM declared for this crash information collection mechanism.
- Only Cisco 7000 series routers and the RSP are activated with new crash information mechanism. Cisco 4500 and other routers will see no difference. [CSCdj12951]
- A crash was caused by an AVL node that was freed but was still accessed during tree traversing. This problem was a result of the node being deleted and freed in the middle of a tree walk. This is an IS-IS (using AVL tree) specific problem. [CSCdj18685]
- On rare occasions after the router powers up, after the router is reloaded, or after the microcode is reloaded, the PA-2CT1/PRI port adapter on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) might stop transmitting data because of a framer lockup condition.
- To verify that the interface is functioning properly after a system power-up, system reload, or microcode reload, a successful ping command must be confirmed across the interface. If the ping fails and the line and protocol are up, it might indicate a framer lockup condition. To verify that a framer lockup condition exists, disable keepalives on the interface for the duration of the test. After disabling keepalives wait about 40 seconds, use the ping command, and use the show interface command to check the line and protocol status. If the ping command fails and the line and protocol are up after disabling keepalives, a framer lockup condition exists.
- If this rare framer lockup condition occurs, you must first reload the microcode and then check the status of the interface (using the procedure above). If the condition still exists, you must reload the router and check the status of the interface again. To fully release this condition if a reload of the microcode and router are not sufficient, you must power cycle the router. [CSCdj15129]
- On rare occasions after the router powers up, after the router is reloaded, or after the microcode is reloaded, the PA-2CE1/PRI port adapter on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) might exhibit CRC errors on all receive-side packets. These packets are subsequently dropped by the port adapter.
- To verify that the interface is functioning properly after a system power-up, system reload, or microcode reload, a successful ping command must be confirmed across the interface. If the ping fails and the line and protocol are up, it might indicate this CRC error condition. To verify that this CRC error condition exists, disable keepalives on the interface for the duration of the test. After disabling keepalives wait about 40 seconds, use the ping command, and use the show interface command to check the line and protocol status. If the ping command fails and the line and protocol are up after disabling keepalives, this CRC error condition exists.
- If this rare CRC error condition occurs, you must first reload the microcode and then check the status of the interface (using the procedure above). If the condition still exists, you must reload the router and check the status of the interface again. To fully release this condition if a reload of the microcode and router are not sufficient, you must power cycle the router. [CSCdj15134]
This section describes possible unexpected behavior by Release 11.1(16)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(16)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(17)CA or later.
- The RSP crashes at rsp_fs_free_memd_pack. This might be caused by older versions of AIP microcode in the router that is crashing or in routers that are supplying this router in the same network. [CSCdj59745]
- A situation occurs when bridging between LANE and FDDI where a Cisco router is not handling the packets appropriately. This case is under investigation. [CSCdj51644]
- With serial links on VIP port adapters, users experience incrementing interface resets and serial line flaps under heavy load. The workaround is to turn off fair queueing. [CSCdj60813]
- Under rare circumstances, a router with BGP enabled sees BGP updates with a duplicate community attribute, which triggers the neighbor to reset. [CSCdj64103]
- With certain route map configurations or soft reconfigurations, the
localpref for a path might be set to 0, resulting in the wrong path being selected. [CSCdj55839]
- On an FSIP 4- or 8-port card when running at clock rates greater than 4 Mbps, you might see overruns/underruns. There is no workaround at this point. The serial controllers on the FSIP are limited to 6.132 Mbps each. The 4-port FSIP has one serial controller, and the 8-port FSIP has two, one for ports 0-3 and one for ports 4-7. When one or more ports consume the entire 6.132-Mbps bandwidth, you need to administratively shut down the other ports on the serial controller. If you exceed the 6.132-Mbps limitation, underruns/overruns are expected. [CSCdj04555]
This section describes possible unexpected behavior by Release 11.1(15)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(15)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(16)CA or later.
- A Cisco 7200 series or Cisco 3600 series router might reload with a bus error when performing a protocol translation between X.25 and PPP. To workaround this problem, enable header-compression passive in the translate statement. [CSCdj37556]
- Channelized E1 port adapters (PA-2CE1) that are configured as ISDN PRI in a Cisco 7500 router can quickly run out of transmit queue (txq) credits and lock up, especially if call turnover is high. To remove this lock-up condition and get the port adapters functional, reload the router.
- The problem can be seen with the show controller cbus command, issued when the port adapters are in a deadlock condition. To check if credits are lost, issue a show contr cbus command several times. If credits are lost, the txacc value should never go back to txlimit. Eventually, all credits will be depleted, and the controller will cease to function.
- Additional indicators are that ISDN Layer 2, as seen with the show isdn status command, remains in the TEI-ASSIGNED state. Also, you might see "output hang" when you issue the show interface command for the D channel. [CSCdj50587]
- A VIP interface card on an RSP router might see a crash under some unusual circumstances. If you encounter this problem, the symbols resulting from decoding the EPC in the show diag output will show emulate_load_store. [CSCdj24283]
- Consecutive rapid POS interface transitions might cause the VIP to crash at configsonetplx(0x60112454)+0x110. [CSCdj26196]
- When BGP dampening is on, a withdraw and announce combination for a route is counted as two flaps. A flap should not be counted when a withdrawn route is re-announced. [CSCdj45833]
- A VIP2 card with a Token Ring port adapter installed crashes and resets the interface. Rebooting sometimes helps to recover. [CSCdj46564]
- The Cisco 7206 router reloads when the CSU is powered off. There is a connection via ATM to an ISP doing ATM to frame to the CSU that connects to a Cisco 2500. If the CSU is powered down within 1 to 2 minutes, the Cisco 7206 reloads with a bus error. [CSCdj51914]
- With a large number of subnets, a CPUHOG message like the following might be generated:
7000 running 11.0.16 getting:
.Sep 30 17:55:32:%SYS-3-CPUHOG: Task ran for 2608 msec (73/65), Process = BGP
scanner, PC = 176388
- [CSCdj45966]
This section describes possible unexpected behavior by Release 11.1(14)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(14)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(15)CA or later.
- The display from a show controller command on a PA-2E3 port adapter in a Cisco 7500 series or Cisco 7200 series router might inaccurately report the hardware revision number of the port adapter. A Cisco 7200 series might report "Version 2" with the show controller serial command. A Cisco 7500 might report "HW Revision 0x2" with the show controller serial or show controller cbus commands. Hardware revision 3 is the first available revision number for this port adapter. To workaround this problem if you need to determine the hardware revision for the PA-2E3 port adapter, you must look at the board. [CSCdj46388]
- The no buffer counter on the ATM interface of the ATM-CES port adapter for the Cisco 7200 series does not increment correctly. It will spuriously record a no buffer even if hardware buffers are available. [CSCdj31158]
- Memory fragmentation can result if many radixmnodetypes are malloced/freed by Cisco IOS software in a short period. We recommend you upgrade to larger DRAM modules (128 MB) especially for ISP sites. [CSCdj19977]
- When the OSPF interface command ip ospf authentication-key key is configured with a key length that is longer than 19 characters (including any trailing spaces), the OSPF internal data is corrupted and a following write terminal or show running-config command could reload the router. Also, this problem might occur with the ip ospf message-digest key-id md5 key command if the key length is longer than 36 characters. To work around this problem, do not enter a key longer than 19 characters (or 36 characters for the ip ospf message-digest command), either encrypted or not. [CSCdj37583]
- A defect in "ip_cache_ager" was found at a customer site under abnormal conditions where both ends of a high-speed point-to-point link were configured with the SAME IP address. This is not expected to occur in more normal circumstances, nor have we been successful in recreating this problem in the laboratory. One known workaround is not to configure the same IP address on both ends of a high-speed link. [CSCdj05999] [CSCdj17314]
- The Cisco 7206 brings serial interfaces down as soon as the fourth T1 line is enabled on the router. After the fourth line is connected, the lines will remain up for approximately 15 minutes and then display the following message: %OIR-3-SEATED: Insert/removal failed (slot 4), check card seating. [CSCdj12822] [CSCdi80889]
This section describes possible unexpected behavior by Release 11.1(13a)CA1. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(13a)CA1. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(14)CA or later.
- When running IP Multicast over LAN Emulation (LANE) on the ATM port adapter, there is a possibility that the ATM port adapter will receive cell FIFO overrun. This will subsequently cause related input packets to be dropped. This condition has been observed when the IP Multicast traffic reaches a certain rate. While this problem is negligible when the source traffic is shaped at a lower rate, we recommend that IP Multicast over LANE not be used until the cause of the problem is found and a fix is determined. [CSCdj02702]
- A Cisco 7200 series with an 8 port serial adapter might experience a hang condition and display the following error messages "%SYS-2-INLIST: Buffer in list" and "%Link-2-NOSOURCE: source idb not set." To alleviate the hang condition, reload the router. [CSCdj03646]
- A VIP2 with a HSSI and Fast Ethernet port adapter crashes due to a memory corruption. Console is showing %VIP2x-1-MSG, %DBUS-3-DBUSINTERR, %RSP-3-RESTART, and %RSP-3-FOREVER messages. [CSCdj21320]
- When an new E1 is added, the PA-8T might go into an unstable up-down situation. This instability might cause the VIP2-20 to restart.[CSCdj24584]
- The ATM port adapter on Cisco 7500 series routers might experience call setup failures and display the following messages "AIPREJCMD" and "AIP-3-FAILCREATEVC." The problem is currently being investigated and a resolution will be available in the near future. [CSCdj25270]
- In RSP-based platforms, the following error might occur that indicates a problem with a hardware enqueue: "%RSP-2-QAERROR: reused or zero link error, write at addr 00C0 (QA) log 2600C040, data 00070000 00000000." This might be followed by an "Unexpected exception, CPU signal 10, PC = 0x601C4658" error and the router might reload. This problem is caused by a bad memory access in the diagnostic code handling the original QA error. [CSCdj29751]
- VIP2 FDDI port adapter transparently bridges traffic even though there is no bridge group defined on the interface. A workaround this problem, use the no bridge-group 1 command on the FDDI port adapter interface. [CSCdj24479]
- A spurious memory access can occur when switching from flow switching to process switching using the no ip route-cache command and then back to flow switching using the ip route-cache flow command. [CSCdj08350]
- Register dump has provided valuable information to find out the root cause of a crash especially for memory corruption crashes. This fix enhanced the register dump and crashinfo in general by providing:
- Not only deallocator of a freed block but also the previous deallocator
- Better early memory corruption detection when "debug sanity" is on
- Detect whether the data in a register is inside a malloc block, if so dump the entire malloc block (up to 1 KB)
- Check the contents of the register memory dump for valid RAM address and dump them as well (this is useful to dump places such as pak->datagramstart or hwidb->next. etc.)
- Consolidate all memory dump into up to 96 dump blocks to eliminate duplicate dump on same/nearby area [CSCdj18684]
This section describes possible unexpected behavior by Release 11.1(12)CA1. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(12)CA1. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(13)CA or later.
- When asymmetrical compression algorithms are configured (that is, compress stac on one router and compress predictor on another), both routers can crash or lock up. Realizing that the migration to stac from predictor will cause this problem, the workaround is to shut the interfaces, change compression algorithms on both ends, then start up or use the no shutdown command on the interface. [CSCdj13405]
- The VIP PA-4R port adapter is bridging frames that were aborted by the sender rather than dropping the aborted frames. [CSCdj13409]
- IEEE spanning tree BPDUs are not recognized by a VIP2 with a NP-4R running Cisco IOS Release 11.1(10)CA or 11.1(11). [CSCdj18696]
- An encapsulation change on a POS interface can result in a PCI time out VIP reload. This is due to the POS interface accessing onboard registers before the onboard PLX chips are programmed. [CSCdj08510]
- When a FDDI ring is highly unstable and is having excessive transitions, the FDDI interface may go DOWN/DOWN. To workaround this problem, use the clear interface command. [CSCdj11905]
- Under high traffic conditions the HSSI port adapter may handle the packets abnormally. Customers using VIP2/HSSI port adapters are strongly encouraged to upgrade to an image containing the fix for this bug. See "Field Alert: VIP2 Cisco IOS Software Release Deferrals" for image availability and additional information. [CSCdj18441]
- If one person is doing a write memory command and another person does a show config command at the same time, the router might crash. Seems to be same as CSCdi51059. [CSCdj16985]
- The show ip bgp neigh x.x.x.x adv command with route-map deny community does not work. [CSCdj16922]
- With certain traffic Netflow switching can cause a loss of MEMD buffers causing the interface to hang. [CSCdj19970]
This section describes possible unexpected behavior by Release 11.1(11)CA1. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(11)CA1. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(12)CA or later.
- Under stress condition, when you remove or insert an interface processor card in a powered-up router that contains a VIP2 with an ATM port adapter (PA-A1-OC3MM and PA-A1-OC3SMI), the ATM port adapter reloads. During the reload period, the ATM interface is down and cannot transmit or receive packets. To avoid this problem, do not remove or insert an interface processor card in a powered-up router that contains a VIP2 with an ATM port adapter. [CSCdj13110]
This section describes possible unexpected behavior by Release 11.1(10)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(10)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(11)CA or later.
- Multiring IP/IPX does not function on FDDI interfaces in Cisco 7500 series routers. There is no workaround. [CSCdj00388]
This section describes possible unexpected behavior by Release 11.1(9)CA1. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(9)CA1. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(10)CA or later.
- Multiring IP/IPX does not function in Cisco 7200 series routers. There is no workaround. [CSCdi85841]
- Users might experience FDDI interface Output Stuck errors when running FDDI port adapters along with other high bandwidth port adapters (for example, Fast Ethernet) in the same VIP under very high VIP aggregate bit-rate loads. When this error occurs, the FDDI interface is reset and resumes operation. To workaround this problem, use the FDDI without a second port adapter in the VIP (that is, the other port adapter slot on the VIP must be empty). [CSCdj02254]
- A fix for this problem has been integrated in the hardware. We recommend that you replace the FDDI port adapter. For more information on CSCdj02254, refer to the Field Notice: FDDI Port Adapter Replacement Recommendation posted on Cisco Connection Online (CCO) at the URL listed below.

This section describes possible unexpected behavior by Release 11.1(9)CA. Unless otherwise noted, these caveats apply to all 11.1 CA releases up to and including 11.1(9)CA. These caveats are listed in the 11.1 CA Release Note because they apply to specific platforms supported by Release 11.1 CA.
The caveats listed in this section are resolved in Release 11.1(9)CA1 or later.
- On PA-H and PA-2H HSSI port adapters, users might experience CRC, overrun, and underrun when a second HSSI port adapter is installed and running on the same VIP2. "Overrun" refers to a condition in which the HSSI port adapter sends more data to the VIP2 buffer than the buffer is capable of storing and forwarding. The HSSI port adapter does not have the capacity to reduce the amount of traffic it is sending. Data lost in this overrun condition is measured in packets lost. "Underrun" may occur when data from the VIP2 is sent to the buffer in the HSSI port adapter for transmission over the serial network. Under bidirectional load, the HSSI port adapter might fail to fetch data fast enough on transmit. Underruns will be registered when this occurs. To alleviate this problem, use only one port on a PA-2H. VIP firmware is currently under test to remedy this problem. There is no other workaround. [CSCdi89690]
- Release 11.1(9)CA1 has fixes that alleviate CSCdi89690 but do not completely resolve the problem. For more information on CSCdi89690, refer to the Field Notice: Cisco IOS Software Release 11.1(9)CA1 posted on Cisco Connection Online (CCO) at the URL listed below.
