Determining Your Software Release

To determine the version of Cisco IOS software currently running on either the Catalyst 8510 or the LightStream 1010 switch, log in to the switch and enter the show version EXEC command. The following is sample output from the show version command. The version number is indicated on the second line as shown below:

Cisco Internetwork Operating System Software
IOS (tm) LS1010 W5-5 Software (LS1010-WP-M), Version 12.1(12c)EY

Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

Other Firmware Code

Some of the port adapters supported on the Catalyst 8510 and LightStream 1010 switch have upgradeable FPGA and functional images. The FPGA and functional images include caveat fixes, but in most cases, it is not necessary to upgrade. The release notes that describe the caveats from the FPGA and functional images are available on the World Wide Web at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/l3sw/8540/rel_12_0/w5_6f/rel_note/fpga_rn/index.h tm

For information describing the firmware update process, refer to the section "Maintaining Functional Images (Catalyst 8510 and LightStream 1010)" in the chapter "Managing Configuration Files, System Images, and Functional Images" in the ATM Switch Router Software Configuration Guide.

Feature Set Tables

The Cisco IOS release software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. Table 2 lists the Cisco IOS software feature sets available for the Catalyst 8510 MSR and LightStream 1010 switch in Cisco IOS Release 12.1(12c)EY.

Caveat Symptoms and Workarounds

This section summarizes caveat symptoms and suggested workarounds for the Catalyst 8510 switch and the LightStream 1010 switch.

Note   The maximum number of ELAN LES/BUS pairs that the ATM switch processor interface supports is 10. On configuring a Frame Relay NIW/SIW PVC, a small number of discarded frames are occasionally seen due to CRC errors. These discards happen even without passing traffic.
  • CSCin12744

Symptom: Signaling is reset on other interfaces of the device that are not connected to the peer switch being reloaded.

Workaround: None.

  • CSCin10542

Symptom: After you configure a Point-to-Multi Point connection, if you try to remove the connection from the leaf side, the following message is displayed:

% PVC de-configuration not allowed with snooping on!!
% De-configure snooping first.

Workaround: Delete the PVC or PVP from the root end.

  • CSCin09850

Symptom: When an ATM Soft-VC or Soft-VCP is configured between two interfaces of a Catalyst 8540 MSR using a particular VPI, and a Soft-VC or Soft-VCP is configured with the same VPI, the following error appears:

%ATMCORE-3-INTERNAL_ERROR: atmCore_connAllocateHalfLeg: return resource err.2

The internal error message should not appear when the Soft-VC or Soft-VCP configuration fails.

Plus, the following expected message is seen more than once:

connection creation fails:vpi/vci has been used

The internal error message is not seen when a PVC configuration on an interface is followed by a PVP configuration that uses the same VPI. Also, the internal error is not seen when the interface on which the configuration is being done does not have the resources required by the Soft-VC or Soft-VCP.

After the configuration is executed and then fails, this causes the allocation of the bandwidth requested by the CBR VC even though no VC actually exists. If, for example, N kbps is free on an interface, and a Soft-VC is configured from that interface with a VPI-VCI already in use and uses a CTTR of N kbps, the configuration fails, but all N kbps that were free on that interface are lost. This bandwidth loss is seen only with the CBR service-category.

Note    Using the shutdown and no shutdown commands on the interface does not recover the lost bandwidth.

Workaround: For the Catalyst 8540 MSR, if you switchover the route processor it recovers the lost bandwidth on the interface. No workaround exists on the Catalyst 8510 MSR.

No workaround exists for the following error message:

"%ATMCORE-3-INTERNAL_ERROR: atmCore_connAllocateHalfLeg: return resource err.2

  • CSCin09752

Symptom: If an IMA group exists between a Catalyst 8540 and Catalyst 8510 switches with CBR soft VCs configured between the switches and a link of the IMA group is shut down or fails, the IMA interfaces still display the pervious bandwidth value. This bandwidth value is greater than the actual resources available on the interface and the soft VCs still appear as "up" on both the Catalyst 8540 and Catalyst 8510 switches. This continues to happen as more links are shut down or fail until the 2 CBR soft VCs that require the resources of 7 E1 links still appear as "up" with only 1 E1 link actually "up" between the IMA interfaces and the other 6 links that are shutdown.

Note    This behavior is seen when the links are either deleted from the IMA group or that are shutdown.

Workaround: Use the shutdown and no shutdown commands on the IMA group and it will display the correct values of available and allocated bandwidth.

  • CSCin09205

Symptom: If a VC is down when the switch is reloaded, the ARM subinterface stays UP even though the OAM-state is OAM-Down.

Workaround: Bring the VC UP at least once after a reload.

  • CSCin09194

Symptom: If you configure OAM on a PVC while it is down, the OAM state of the VC is displayed as "not applicable" instead of "OAM-Down" and never changes. This means OAM cells are not sent even after the VC comes UP. This only occurs if AIS is not enabled for the VC.

Workaround: Configure OAM for a VC only when it is in UP state.

  • CSCin06080

Symptom: On a LightStream 1010 switch with an E1interface connection, Detailed Device Report shows "slot number : N/A" but should display the actual interface slot number.

Workaround: None.

  • CSCin02864

Symptom: On interface ATM0, while breaking the packet into cells, when the MTU size configuration is checked it is checked for the cross-connect ATM interface and not for interface ATM0 itself. This means if the size of the packet exceeds the configured MTU on the cross-connect ATM interface, the following error is displayed:

%LINK-4-TOOBIG: Interface ATM1/1/3, Output packet size of 2008 bytes too big

Workaround: There are two possible workarounds for this condition: either change the MTU size on both ATM interfaces back to the default using the command no mtu in interface configuration mode, or change the MTU configuration on interface atm 0 to match the MTU configuration on the cross-connect interface using the mtu # interface configuration command.

  • CSCdx68903

Symptom: The Catalyst 8510 MSR might encounter a memory leak in ATMSIG processes and this might render the switch unusable after one month of operation.

Workaround: None.

  • CSCdx49779

Symptom: The switch crashes when the IPX encapsulation is changed on Fast Ethernet or Portchannel interfaces.

This might occur after you change encapsulation and then use the shutdown and no shutdown commands.

Workaround: None.

  • CSCdx47684

Symptom: On the LightStream 1010 switch, a PNNI PVC link on an NNI interface might flap after the link stabilizes and the ATM PNNI VC component does not come back up.

Workaround: "Bounce" the PNNI process using the no atm router pnni and atm router pnni configuration commands to disable and enable the PNNI processes.

  • CSCdx29693

Symptom: An ARM configured with subinterface and PVCs loses IP connectivity over the active PVCs.

Workaround: To delete and reconfigure the PVC configuration restores connectivity.

  • CSCdx09652

Symptom: After OAM detects a failure on a PVC terminating on the ATM Router Module (ARM), it fails to remove the adjacency, the directly connected route, and any additional route pointing to the next hop reachable over the failed PVC. This condition might stop traffic.

Workaround: There is no work-around, other than to perform an admin shutdown of the ARM subinterface (if the PVC is the last or only PVC on that subinterface). Alternatively, you could remove the PVC until the problem has been rectified.

  • CSCdx06532

Symptom: The PNNI-MIB object pnniLinkIfIndex(.1.3.6.1.4.1.353.5.4.1.1.9.1.11) returns 0 on the main interface running PNNI.

This problem does not exist in 12.0(13)W5(19c) but exists in 12.0(18)W5(22) and 12.0(20)W5(24a).

Workaround: None.

  • CSCdw95262

Symptom: On Frame Relay soft VCs, all frames sent with DE (discard eligibility) bit set are dropped at the serial interface even when the UPC is configured as "tag-drop" for the softVC.

Workaround: None.

  • CSCdw90604

Symptom: Interoperability problem between LightStream 1010 and Compaq Server with ATM NIC if you pull out the optical fiber connection and reconnect it. If you do so, ILMI keeps restarting, and never stabilizes. You can use the shutdown command on the interface, then disconnect and reconnect the fiber optic connection and use the no shutdown command on the ATM interface to eliminate the problem. These commands cause ILMI to restart correctly.

Note    Using the shutdown and no shutdown commands on the LightStream 1010 ATM interface after the disconnection and reconnection does not solve the problem.

Workaround: Follow these steps:
1. Reboot the server.
2. Use the shutdown and no shutdown commands on the des ATM-Switch-Interfaces.
3. Restart of the ATM-NIC (only the NIC interface).
4. Bind the TCP-Stack.

  • CSCdw84540

Symptom: LightStream 1010 switches running 12.0(X)W5 IOS may not completely adhere to the ITU-T Q.2971 "B-ISDN DSS2 UNI Layer 3 Specification for Point-to-Multipoint Call/Connection Control". This could affect interoperability.

Workaround: Configure UNI Version 3.1 on the LightStream 1010 ATM interfaces if the point-to-multipoint interoperability issue is observed.

  • CSCdw79090

Symptom: Occasionally after a system crash or route processor switchover you may see a PVC connection that exists in the interface software configuration but not does appear configured in the interface hardware.

Workaround: Perform an OIR on the interface module with the failed connection or perform a route processor switchover to restore the connection on the interface hardware.

  • CSCdw72923

Symptom: ATM PVCs configured on the ATM0.X subinterfaces might appear under the ATM0 main interface. This leaves the subinterfaces with out ATM PVCs and no connectivity. This only occurs after a switch reload, power cycle or using the force-failover main-cpu command on Catalyst 8540 MSRs running IOS Release 12.1(7a)EY, 12.1(7a)EY1, or 12.1(10)E.

Workaround: Use the no sync dynamic-info command to disable sync dynamic-info.

  • CSCdw70257

Symptom: A Catalyst 8510 MSR configured with an IMA (inverse multiplexing for ATM) bundle might not log link up or down status messages. Only messages displaying clock change are logged. See the following example:

 04:23:21: %CLOCKSW: Switching from ATM1/1/1 to ATM1/1/0
 04:24:26: %CLOCKSW: Unswitching from ATM1/1/0 to System
 04:25:21: %CLOCKSW: Switching from System to ATM1/1/1
 04:26:06: %CLOCKSW: Unswitching from ATM1/1/1 to System

As each interface recovers its revertive clocking and the source is recovered, link functionality is restored. Confusion can be created if there are multiple links flapping and only CLOCKSW messages are received without reporting status of the interface.

The correct physical status can be viewed properly with show ima interface and show ima interface atm card/subcard/port max detail to display the status of the interface and counters.

Note    This behavior is not seen when the switch is configured as stand alone.

Workaround: None.

  • CSCdw67033

Symptom: If configuring RFC1483 bridging on the ATM router module, when certain RFC 1483 bridging PVC cable connections are unplugged the Catalyst 8540MSR CPU utilization will become very high. This could last a few hours until you shutdown the corresponding bridge-group subinterface on the ATM router module. Only shutting down the physical ATM port will not help.

Workaround: Shutdown the corresponding bridging group subinterface on ATM router module.

  • CSCdw65903

Symptom: Multiple Cisco products contain vulnerabilities in the processing of Simple Network Management Protocol (SNMP) messages. The vulnerabilities can be repeatedly exploited to produce a denial of service. In most cases, workarounds are available that may mitigate the impact. These vulnerabilities are identified by various groups as VU#617947, VU#107186, OUSPG #0100, CAN-2002-0012, and CAN-2002-0013.

This advisory is available at http://www.cisco.com/warp/public/707/cisco-malformed-snmp-msgs-pub.shtml.

Workaround: None.

  • CSCdw55504

Symptom: AIS signal taken into account with 2 seconds delay.

Workaround: None.

  • CSCdw45551

Symptom: On the LightStream 1010 switch, the following error message appears if your switch is using IOS Release 12.0(19)W5(23):

Jan 15 12:34:19.734 CET:%ATMSIG-3-FAILXCONN: Xconnect failed, xconn fail

        CONN_INSTALL_RESULT_HW_FAIL

It appears frequently without any other preceding error messages and software/hardware changes on the switch.

Workaround: Upon its first appearance the issue was avoided by reloading the switch.

  • CSCdw44534

Symptom: Excessive CLP0 discards on TSCAM for PD enabled VCs.

Workaround: None.

  • CSCdw41639

Symptom: The LightStream 1010 switch might drop OAM F5 END Loopback cells under its default configuration of OAM intercept (which is enabled by default).

Workaround: Disable OAM intercept to avoid dropping F5 OAM cells.

  • CSCdw40185

Symptom: Multicast packets of some specific lengths (121 bytes to 240 bytes) cause a portstuck condition on the ATM router module interfaces.

Workaround: None.

  • CSCdw39079

Symptom: SSH fails with the CRC-check failed error message sometimes.

Workaround: None.

  • CSCdw33859

Symptom: If you use the no negotiation auto command in interface config mode on a 2-port Enhanced Gigabit Ethernet interface module with GMAC-D2 (hw-version 6.0 onwards), any packets larger than 1518 bytes or less than 64 bytes are filtered by the GMAC (Gigabit Ethernet Media Access Controller).

Workaround: Reload the particular interface using the epc portstuck-manual-reload interface card/subcard/port command.

  • CSCdw33641

Symptom: The Catalyst 8540MSR and LightStream 1010 console hangs when using the hw-module {slot number | subslot subslot/subcard} reset command on the Frame Relay E1 interface nodule.

Workaround: Shutdown all controllers in the module before using the hw-module {slot number | subslot subslot/subcard} reset command.

  • CSCdw33267

Symptom: Load balancing between provider edge (PE) to provider (P) switches and provider edge to provider edge does not work. If MPLS is enabled on the switch router running Release 12.1 software, MPLS might not re-resolve all dependant routes for a path if you enter the shut/noshut or the clear ip route commands on the outgoing interface of the next hop router.

Workaround: None.

  • CSCdw31172

Symptom: Unusual delays in Frame Relay VC counters update on Frame Relay ATM interface modules.

Workaround: None.

  • CSCdw27518

Symptom: Frame relay PVC goes down and remains down after enabling the OAM feature and performing a shut / no shut on the serial interface. However, traffic flow is not affected through the PVC even though it appears down.

Workaround: Disable OAM and shut/no shut the serial interface to force the interface to appear back up.

  • CSCdw23597

Symptom: Globally changing TDP to LDP or changing LDP to TDP sometimes causes a loss of neighbors.

Workaround: Following is a four-step work-around:

1. Configure no tag-switching ip on both sides.

2. Configure the desired protocol at each end.

3. Wait two minutes.

4. Configure tag-switching ip at each end.

  • CSCdw22219

Symptom: If PNNI continuously receives a high rate of corrupted PTSP packets over a long period of time, it can cause a large number of internal node numbers to be generated for bogus Node IDs. If the number of internal node numbers reaches 1032, it can cause a crash.

Under normal conditions, PTSP packets should have a very low rate of being corrupted. But if PNNI interfaces are tunneled through a network where the connections are rate limited to a too low rate it can force cell drops which can corrupt packets.

Workaround: Troubleshoot and remove the cause of PTSP packet corruption.

  • CSCdw22042

Symptom: A point-to-multi point failure might occur if a physical hardware connection does not exist but a virtual software connection is configured. Due to the connection delink failure the following error message appears on the console:

%ATMCORE-3-INTERNAL_ERROR: connDeLinkP2mpPeerLegs: wrong root FSM

Workaround: None.

  • CSCdw14139

Symptom: The combined installation of TSCAM and a mixed interface module might cause the following mmc_queuecell failure message to appear:

 
 "%AAL5-3-INTERNAL_ERROR:  aal5send: mmc_queuecell failed "

Workaround: None.

  • CSCdw11289

Symptom: The ATM router module has only 147 Mbps of resources available on the ATM interfaces. The following display shows the available bit rate for an ATM router module ATM interface:

Switch# show atm interface resource atm 0/1/1
   [Information Deleted]

     Best effort connections: 0 pvcs,  0 svcs

Workaround: None.

  • CSCdw10624

Symptom: You might see a Bus Error exception at get_slot_ptr while trying to do the continuous snmpwalk on the ciscoLS1010SubModuleGroup object of CISCO-RHINO-MIB and simultaneously toggling the redundant power-supply after at least one route processor switchover.

Workaround: None.

  • CSCdw09750

Symptom: Inverse ARP does not succeed for a Frame Relay PVC terminated on ATM router module.

Workaround: None.

  • CSCdw04573

Symptom: The enhanced ATM router module subinterface counters do not get updated.

Workaround: None.

  • CSCdw02689

Symptom: When reloading the switch the following error message appears after a varying number of SVCs are setup.

 00:20:42: %ATMCORE-3-INTERNAL_ERROR: atmCore_connCheckSpot: exhausted vpi/vci

Workaround: None

  • CSCdw01726

Symptom: A Simple Network Management Protocol version 3 (SNMPv3) user is created by using message digest 5 (MD5) authentication with the following commands:

  • snmp group groupy v3 auth
  • snmp user abcdefghij groupy v3 auth md5 abcdefghij

An SNMP walk is performed, the configuration is saved, and the switch is reloaded.

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l 
AuthNoPriv 194.12.224.11

It is working and a debug snmp header shows this:

Incoming SNMP packet
 : v3 packet    security model: v3  security level: auth
 username: abcdefghij

A second SNMP walk is performed:

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l 
 AuthNoPriv 194.12.224.11

After the second SNMP walk is performed, the command does not return any output and the debug snmp headers show this:

Incoming SNMP packet
 : v3 packet  security model: v3  security level: noauth
 : username: abcdefghij

Workaround: None.

  • CSCdv88029

Symptom: PNNI and SSCOP signaling does not come back up on the Catalyst 8540 MSR OC48 interfaces after a power loss and restart.

Workaround: None.

  • CSCdv87337

Symptom: Ping fails when one of the two parallel soft VCs is missing.

Workaround: Use clear bridge command to reset bridge forwarding cache.

  • CSCdv85162

Symptom: LDP session does not go down when you shut the enhanced ATM router module interface. When tag-switching is configured on a Fast Ethernet interface and the controlling ATM router module is either not configured or shutdown, TDP will come up but the tag packets received on the Fast Ethernet interface will be dropped because there is no controlling ATM router module to process the packets.

Workaround: Make sure the Fast Ethernet interface is linked to an active controlling ATM router module.

  • CSCdv82794

Symptom: An ATM router module interface with a PVC configured might experience a port stuck condition.

Workaround: None.

  • CSCdv67501

Symptom: Once the route processor switches over the following error message is seen on new Primary if we have a Gigabit processor interface module:

%ONLINEDIAG-6-ACCESS_TEST_WARNING: Unable to read from card in slot 10 sub_card 0.

Enter the show diag online access command to get more details about the failure.

Workaround: None.

  • CSCdv65055

Symptom: Configuring different encapsulations on 2-port Gigabit Ethernet subinterfaces clears the existing active configuration when multiple subinterfaces are present on a main interface.

Workaround: All subinterfaces have to be configured with the same encapsulation (either 802.1 Q or Inter-Switch Link [ISL]).

  • CSCdv62465

Symptom: A tag switching traceback might appear when an interface is shut.

Workaround: None.

  • CSCdv60858

Symptom: A crash occurs while configuring BVI/eigrp, or while powering off the redundant power supply.

Workaround: None.

  • CSCdv56244

Symptom: Catalyst 8540 CSR eight port Gigabit Ethernet interface modules fails to run CLNS.

Workaround: Update to IOS release 12.1(11b)E.

  • CSCdv55117

Symptom: A Catalyst 8540 MSR locks up when configuring ATM port snooping. The switch lockup can occur if ATM port snooping is configured without an analyzer connected to the snoop port.

Workaround: 1.- Load the most recent version of Cisco IOS.

or

2.- Have the analyzer connected to the snoop port prior to configuring ATM port snooping. Keep the analyzer connected until the snoop configuration is removed.

  • CSCdv49358

Symptom: When a circuit emulation service (CES) circuit that is carrying traffic is removed, no warning message is shown.

Workaround: None.

  • CSCdv48352

Symptom: When running Cisco IOS Release 12.0(18)W5(22) on a Catalyst 8540 MSR, or on a LightStream 1010, interoperability problems occur when peers run an older IOS version, and tunnels and SVC/Soft VCs are used.

Workaround: Upgrade all switches to the most current IOS release.

  • CSCdv45286

Symptom: Point-to-multipoint PVCs that are configured by using SNMP are not preserved across route processor switchovers.

Workaround: Disable the dynamic synchronization feature.

  • CSCdv43426

Symptom: When a Catalyst 8540 MSR has a large number of inverse multiplexing over ATM (IMA) port adapter modules, a message similar to the following is generated:

-Process= "IMAPAM Onesec", ipl= 6, pid= 70 
-Traceback= 600D8280 600D8644 6049F928 600C03CC 600C03B8
%SCHED-3-THRASHING: Process thrashing on watched message event.

Workaround: None.

  • CSCdv39810

Symptom: When both the primary and secondary route processors are up and running, on the secondary the output of the show atm interface resource atmx/y/z command for an inverse multiplexing over ATM (IMA) interface shows all the available cell rates as zero. This results in loss of all VCs (that pass through the IMA interface) requiring guaranteed service (such as CBR, VBR, ABR with MCR, UBR).

Workaround: None. Upon switchover, the new primary route processor recovers from the problem.

  • CSCdv39328

Symptom: When using a Packet Over SONET card, the Open Shortest Path First (OSPF) routes do not come up after a route processor switchover, even though they were up before the switchover.

Workaround: None

  • CSCdv35065

Symptom: PNNI goes to down state on all interfaces, and all adjacency is lost.

Workaround: None.

  • CSCdv32093

Symptom: An LightStream 1010 can reload when VP tunnels are created and removed.

Workaround: None.

  • CSCdv22476

Symptom: The Soft-VC permanent virtual connection (PVC) status is indicated as ACTIVE only when the Soft VC is established, and its connection state is UP. If the Soft VC is not connected, the source end of the Soft VC indicates the PVC status as INACTIVE instead of ACTIVE, and the destination end of the Soft VC does not exist, and therefore indicates the PVC status as DELETED.

Workaround: None.

  • CSCdv21398

Symptom: The Management Information Base (MIB) object "ifAdminStatus" shows "UP" for an ADMIN DOWN E1 Controller after a reload or a route processor switchover.

Workaround: Enter the no shutdown/shutdown command sequence on the controller.

  • CSCdv15294

Symptom: When Frame Relay/ATM Network Interworking (FRF.5) is configured on a Catalyst 8540, traffic above the peak information rate is dropped, and the INPUT ERROR counter is incremented, rather than the INPUT DROPS counter.

Workaround: None.

  • CSCdv15245

Symptom: With a Frame Relay-ATM Soft-VC setup in FRF5, UPC on the passive side is always set to PASS, regardless of the hard setting on the serial interface with the frame-relay upc-intent tag-drop command. The default is PASS. When this is changed to tag-drop, the configuration does not reflect the change and the show vc int serial command always shows the UPC intent as PASS.

Workaround: None.

  • CSCdv15238

Symptom: Cisco Discovery Protocol (CDP) does not work over Portchannel platforms.

Workaround: None.

  • CSCdv13291

Symptom: After the simultaneous rebooting of switches terminating the active and passive side of Soft-VC for FRF5, randomly Soft-VPC stays up but, traffic might be dropped on the Frame Relay interface module. This might occur either on the active side of Soft-PVC or on the passive side of the call.

Workaround:

The Frame Relay interface module starts forwarding traffic only after you use the shutdown and no shutdown commands on the serial interface.

You might see the following error message when you reset the Frame Relay interface module:

Error Message: Channel-Group 1 State Change on FR-PAM failed 1

For additional details, refer to DDTS CSCdv17817.

  • CSCdv11518

Symptom: After the Tag Distribution Protocol (TDP) toggles from down to up ("flaps") on the Label Controlled ATM (LC-ATM) interface, it takes a long time for the interface to become TDP ready. Entering the show tag-switching tdp discovery command might indicate that TDP is not ready, and TVCs might still be allocated on the interface. This can occur under stressful conditions in which cross-connections fail to be de-allocated on the ATM switching fabric.

Workaround: None.

  • CSCdv07613

Symptom: Under stressful conditions such as large topology changes, TVC cross-connections might fail to be removed from the ATM switching fabric, causing the TC-ATM function to repeat attempts to remove the TVCs. This might lead to the TC-ATM state process entering a bad state, and to an error message being displayed.

Workaround: None.

  • CSCdv06370

Symptom: Not all of the contents of the atmVcCrossConnectTable can be seen after the removal and re-insertion of a module. The message:

%ATMCORE-3-INTERNAL_ERROR: ATOM ERROR: ifCB_p=NULL for lowIf 

is seen on the console during some Simple Network Management Protocol (SNMP) get operations.

Workaround: None.

  • CSCdv00784

Symptom: The Catalyst 8540 MSR switch may ignore certain commands from the NVRAM after a reboot. This appears most often on switches with dual route processors.

Workaround: Create a connection traffic index and use that number for the set up of the PVC.

  • CSCdu86398

Symptom: What is present in the Patricia trie in the Ethernet processor interface is out of synchronization with what is present in IP Cisco Express Forwarding (CEF). This might cause connectivity problems. This problem only exists on Ethernet processor interfaces; entries in the Switching Database Manager (SDM) on Gigabit processor interface cards are not affected.

Workaround: Find the route (for example, the route network_x) that is not consistent with IP CEF; enter (in the case of this example) the clear ip route network_x command.

  • CSCdu83797

Symptom: Some point-to-multipoint crossconnnect entries are missing from the atmVcCrossConnectTable when the point-to-multipoint root if-index is higher than the if-index of the leaves.

Workaround: None.

  • CSCdu83707

Symptom: Interfaces with Tag enabled get stuck in the TDP not ready state.

Workaround: None. The only way to bring up the Tag on such interfaces is via system reload.

  • CSCdu83704

Symptom: During TagVC installation, if the switch driver returns an error, the Connection Manager leaves the TagVC in the wrong FSM state. This can lead to TVCs existing on an interface when there are no tag bindings.

Workaround: None; reload the switch to clear such unused TVCs.

  • CSCdu82922

Symptom: When running Cisco IOS Release 12.0(13)W05(19), a bus error causes the system to restart. This occurs when an 8-port Gigabit Ethernet card with control traffic is at or near its traffic capacity.

Workaround: None.

  • CSCdu78141

Symptom: If a large frame or packet (more than 6096 Bytes) is received on the tag control virtual circuit (0/32 of an interface enabled for tag switching), the frame is not purged from the switch fabric. Subsequent packets received on this virtual circuit are dropped, causing the Tag Distribution Protocol (TDP) and the routing session (OSPF) to time out.

Workaround: Disable, then re-enable, tag switching on the affected interface; subsequent occurrences can be avoided by increasing the queue depth, using the following entry:

atm threshold 2 max-queue-limit 511

  • CSCdu78056

Symptom: The SNMP TRAP object ccrCpuStatusChange returns an invalid value.

Workaround: None.

  • CSCdu74491

Symptom: After reloading the core switch, all neighboring switches running 12.0(16)W6(21) or 12.0(16)W6(21a) crash, and a message similar to the following is generated:

  • CSCdu69809

Symptom: A port of a 4-port DS3 port adapter for LightStream 1010s and for Catalyst 8540s is in a yellow or red alarm state, and stops sending DS3 framing for a brief time when the alarm is cleared from the interface and the interface transitions to an UP/UP state. The loss of frame (LOF) can be seen when the Acterna tool TBERD is connected to the TX port of the DS3 port.

Workaround: None.

  • CSCdu57077

Symptom: In a network running cell-mode MPLS (tag switching) with a large number of IP routes (and consequently, with many TVCs being setup), a 16-port OC-3 interface module might fail to allocate a new TVC on a bind request and print out the below error message. This occurs even though the number of TVCs currently set up does not reach the limit of VCs supported on that interface or the cross-connect interface.

 Jun 22 20:49:02.011: %TCATM-4-RESOURCE_LIMIT: VC resource exhausted on ATMx/y/z


Workaround: Enter the shutdown command followed by the no shutdown command on the interface for which the error message appears.

  • CSCdu56774

Symptom: In Cisco IOS Release 12.1(6)EY and earlier, only two equal-cost IP paths were supported on Fast Ethenet and Gigabit Ethernet interface modules that were based on an Ethernet processor interface.

Workaround: Upgrade to Cisco IOS Release 12.1(7a)EY; in that release, four-path load balancing for IP is available through use of the epc epif-4-path-lbal command.

  • CSCdu50525

Symptom: The EIGRP Summary Routes are not properly populated in the adjacency table when a default route also exists. This affects the Fast Ethernet and ATM router module interfaces, but does not impact the Gigabit Ethernet interfaces.

Workaround: None.

  • CSCdu44352

Symptom: A Cisco edge services router (ESR) that is running Cisco IOS Release 12.1(2)E1 experiences interoperability problems when an ATM traffic descriptor information element is included in the CONNECT message on a non-negotiated link. Under such conditions, a STATUS message is sent with cause "invalid information element contents (100)" and call will not succeed. This problem is observed when Cisco routers are connected to other vendor switches like FORE, and occurs only when UNI version is 4.0.

Workaround: None.

  • CSCdu44017

Symptom: After deleting a connection, an immediate request to re-install with the same VPI/VCI results in connection-creation failure messages.

Workaround: Increase the bit map size from 32 to 64, to avoid reuse of the same VPI/VCI immediately after a call is released.

CSCdu39277

Symptom: After performing consecutive OIRs of three traffic-shaping carrier modules (TSCAMs) in a chassis more than 20 times, memory allocation fails. Because the TSCAMs require 2 MB of contiguous memory, this failure might occur on a system with severely fragmented memory.

Workaround: Do not perform a large number of consecutive OIRs on the TSCAM and do not perform an OIR on a module that has a large number of VCs.

  • CSCdu35462

Symptom: After a reload, the switch router's memory might be corrupted. This occurs after the following error messages are displayed:

 TLB (store) exception occurred on ... 
 dcl-dram-excep: A3420019, dcl-memd-excep: 60C10100, dcl-io-excep: 012C1580" 
 TLB (load or instruction fetch) exception occurred on 00/05/03 10:38:16 ...

 " *** Unknown External Interrupt *** Stacked Cause = 0x0, Stac

Workaround: None.

  • CSCdu24272

Symptom: When entering the show atm ilmi-status command the switch shows the 0.0.0.0 as a peer IP address even though a loopback address is configured.

Workaround: None.

  • CSCdu20618

Symptom: One side of a circuit emulation service (CES) E1 port of a LightStream LS1010 switch connection remains consistently in the YELLOW alarm or ALARM INTEGRATION state.

Workaround: None.

  • CSCdu21174

Symptom: A switch router with an eight-port Gigabit Ethernet interface module might forward duplicate broadcasts when bridging is configured on a trunk.

Workaround: None.

  • CSCdu01489

A ROMMON configuration might not work properly.

Symptom: A ROMMON configuration might not work properly on a slot after performing an OIR on the interface module in that slot.

Workaround: Reload the switch router.

  • CSCdt96927

Symptom: The Internetwork Packet Exchange (IPX) statistics sometimes fluctuate when no traffic is flowing through the interface. The only affected functionality is IPX statistics.

Workaround: None.

  • CSCdt96389

Symptom: After rebooting the switch router, Ethernet interfaces might have invalid MAC addresses, causing connectivity problems over that interface.

Workaround: Enter the shutdown command and then the no shutdown command on the affected Ethernet interfaces.

  • CSCdt93866

There might be a buffer overflow.

Symptom: Sending a crafted control NTP packet might cause a buffer overflow.

Workaround: Include the "ntp access-group serve-only" line in the configuration of the router.

  • CSCdt91339

Symptom: In the ATM-MIB there is an atmVcCrossConnectTable that allows SNMP to create VC Cross-connects. It is not possible to create multipoint connections. At the time of creating the second entry corresponding to the multipoint connection, SNMP reports the following error:

# ./snmpset -c private lore atmVcCrossConnectRowStatus.8431167.3.0.51.2.0.41 integer 5 atmMIB.atmMIBObjects.atmVcCrossConnectTable.atmVcCrossConnectEntry.atmVcCrossConnectRowStatus.8431167.3.0.51.2.0.41 : INTEGER: createAndWait # ./snmpset -c private lore atmVcCrossConnectRowStatus.8431167.3.0.51.3.0.55 integer 5 snmpset: Agent reported error with variable #1. .iso.org.dod.internet.mgmt.mib-2.atmMIB.atmMIBObjects.atmVcCrossConnectTable.atmVcCrossConnectEntry.atmVcCrossConnectRowStatus.8431167.3.0.51.3.0.55:  SNMP: A general failure occurred on the agent.

Workaround: None.

  • CSCdt86157

Symptom: The snmp polling of the virtual path mibs atmVplLastChange and atmVplOperstatus results in unavailability of the virtual path. But the polling of the virtual circuit in this virtual path states that it is available.

Workaround: None.

  • CSCdt83187

Symptom: On the LightStream 1010 switch when you try to use the atm rmon collect interface command you receive the following error:

ATM-RMON Error: Entry not found

Workaround: None.

  • CSCdt73634

Symptom: If an interface comes up after the system initialization, the scheduler for that interface might not be programmed correctly. Since IMA interfaces comes up after system initialization, IMA interfaces are usually affected by this.

Workaround: Enter the shutdown command on the IMA interface. Take the first link on the IMA interface out of IMA group. Bring that interface up. Shutdown that interface and then make it part of IMA group. Enter the no shutdown command to bring the IMA interface up.

  • CSCdt71010

Symptom: The ifTable indexes do not match the MIB-II table indexes.

Workaround: None.

  • CSCdt63813

Symptom: A LightStream 1010 switch router might automatically reload. When you enter the show version command, the switch reports the reason as "System was restarted by error - a Software forced crash". In addition, log error message might say:

"SYS-6-BLKINFO: Corrupted @redzone blk"

Other messages indicating memory corruption might also occur.

Workaround: None.

  • CSCdt63152

Symptom: HSRP cannot be configured on Cisco IOS Release 12.1(5)EY1 image on the Catalyst 8510 MSR platform.

Workaround: None.

  • CSCdt62215

Symptom: After resetting a switch or router that is connected to a CES port on a LightStream 1010 or Catalyst 8510, there is connectivity about the physical layer.

Workaround: Enter the shutdown command and then the no shutdown command on the CBR interface of the LightStream 1010 or Catalyst 8510.

  • CSCdt53814

Symptom: An ATM router module port configured for transparent bridging and in blocking state may forward certain frames.

Workaround: Ensure that a non-ATM router module port is in blocking state. If this is not feasible, physically shutdown the ATM router module port that is in blocking state.

  • CSCdt47492

Symptom: ILMI might stay in the "waitdevtype" state after a redundancy failover. This is because on an OC3 port adapter, each of the 4 ports are served by one processor interface. The first port needs to be set for the other three ports to be able to receive. Sometimes this does not occur on a redundancy failover.

Workaround: Bring up port 0, if problem is seen on ports 1-3, port 4, if problem is seen on ports 5-7, port 8, if problem is seen on ports 9-11, and port 12, if problem is seen on ports 14-15. The ports can be brought up by connecting a loopback cable, or by simply using that port.

  • CSCdt45629

Symptom: When the switch router is under stress because there are greater than 1000 TVCs on a given interface, some TVCs might not get setup successfully and the following error message occurs:

 %TCATM-4-RESOURCE_LIMIT: VC resource exhausted


Workaround: Configure less than 1000 TVCs on interfaces.

  • CSCdt44914

Symptom: The transmit side of a tag-enabled ATM interface may go into the "not TDP ready" state Use the show tag tdp discovery command to verify that it is in the "not TDP ready" state. As a consequence, Tag is inactive on that interface.

Workaround: Enter the shutdown command followed by the no shutdown command. If this does not work, there is no workaround.

  • CSCdt43218

Symptom: The IP PAT tree becomes programmed incorrectly for 1483 SVC after removing the ATM router module. If an SVC is configured on an ATM router module/Enhanced ATM router module card and the card is OIRed, the adjacency available across the SVC will remain valid in the EPIF/XPIF cam. This results in packets destined to that adjacency to disappear.

Workaround: Before OIRing an ATM router module/Enhanced ATM router module card, remove any subinterfaces that have a SVC configurations, then proceed to do the OIR.

  • CSCdt40530

Symptom: When access is made to PNNI tables, a memory leak might occur. This only happens when an Network Management System (NMS) is running SNMP on the switch router.

Workaround: Turn off NMS polling of PNNI tables and instead use the commands for determining any PNNI information.

  • CSCdt38604

A peer switch might not learn an IP address through ILMI-status.

Symptom: An IP address might not be learned by peer switch when using ILMI-status.

Workaround: None.

  • CSCdt24278

Symptom: The ATM router module sets the CLP of all cells to 1 when bridging is configured over a 1483 PVC. This happens for cells being transmitted over the 1483 PVC only.

Workaround: None.

  • CSCdt21568

Symptom: The ATM router module interface shut downs when entering the epc portstuck-manual-reload command with IP traffic. This only occurs when running the epc portstuck-manual-reload command several times.

Workaround: None.

  • CSCdt21513

Symptom: Spurious memory access at lss_arm_atm_adjacency_mac is observed after there is a CLI epc portstuck-manual-reload command entered on two ATM router module interfaces, while two Catalyst 8540 MSRs are connected.

This has no functionality impact.

Workaround: None.

  • CSCdt18467

Symptom: Port stuck messages might not log into the system log.

Workaround: None.

  • CSCdt17850

Symptom: The outbound ACL fails to filter packets in the subinterface when the static ARP is configured and the ACL is used with it. If a static ARP is configured and the same address is moved from an interface to a subinterface of the same interface, the static ARP entry remains associated with the main interface itself.

Workaround: When the IP address is reconfigured to a subinterface of a main interface, you then need to delete and reconfigure the ARP address.

  • CSCdt17751

Symptom: The following operations will result in a CPU HOG and a CPU HOG error message:

  • when a TSCAM is inserted or removed from the chassis
  • when a Port Adapter Module (PAM) is inserted into or removed from the subcard 0 position of the TSCAM

This will not affect the future operation of the TSCAM.

Workaround: Though this CPU HOG should not have any adverse impact on the network, it is recommended that any online insertion or removal of TSCAMs or Port Adapter Modules in the subcard 0 position of the TSCAM are scheduled appropriately.

  • CSCdt15978

Telnet might be slow.

Symptom: Telnet responses between two switch routers might be very slow.

Workaround: Replace one switch router with another that can accept ISL-frames less than 94B in size (for instance, the Catalyst 5000).

  • CSCdt15169

Symptom: After configuring an ipx network between a Catalyst 8540 MSR and a Catalyst 8540 MSR, and a Catalyst 7500, old buffers detected messages being displayed on the Catalyst 8540 MSR. This occurs with an ATM interface and a Fast Ethernet interface. The Encap is 11 (Novell-Ether). This does not impact any functionality.

Workaround: None.

  • CSCdt13517

Symptom: A LightStream 1010 stops switching some VCs, and log error messages similar to the following example are generated:

Jan  9 12:37:34.793: ATMSIG(12/1/0:0 0,37 - 274610/00): (vcnum:0) XConnected failed To

CONN_INSTALL_RESULT_HW_FAIL

Workaround: Reload the switch.

  • CSCdt11569

Symptom: Oversized packets on the Enhanced ATM router module interface are observed when it is a member of a BVI. This console output relates to the oversized packets on the Enhanced ATM router module interface. The following message is displayed:


00:41:36: %TBRIDGE-4-GIANT: Giant received on ATM3/0/1, 1514 exceeds 1500
DA 0100.5e00.0005 SA 0001.4274.ee09 [0x080045C0]

The system recovers from this. The cause of this may be temporary congestion in the switch fabric, leading to the loss of the last cell of the packet.

Workaround: None.

  • CSCdt10494

Symptom: The ATM router module (8540-ARM-64K) indicates outgoing packets when on an interface that is in an admin down state.

This was observed on Cisco Internetwork Operating System Software IOS (tm) PNNI Software (cat8540m-WP-M), Version 12.0(10)W5(18c). This does not impact the functionality.

Workaround: None.

  • CSCdt09229

Symptom: The switch router might loose traffic on its LANE or 1483 or 1577 interfaces on ATM router module. Frame interfaces or non-LANE interfaces on ATM router module with configured PVCs should pass traffic without any problems. It doesn't matter if the traffic is going to route processor or not, part of the traffic is lost.

Workaround: The switch router will recover from this state only after an OIR of the module or a reload.

  • CSCdt05674

Symptom: A switch with a lot of FC-PCQ connections or running a lot of LANE traffic, might display the following message when the interface carrying most of the traffic is shutdown:

../src-4k-ls1010/mmc_dvr.c 2428 PORT DIED: 0/0/0, taking off line

Workaround: None.

  • CSCdt04810

Symptom: While executing a series of shutdown/no shutdown commands on the ATM router module interface with a large number of CLIP clients (more than 32), the following error message appears on the console:

00:58:16: %SYS-3-MGDTIMER: Uninitialized timer, timer stop, timer = 644B0550.

This does not impact functionality. Enter the shutdown command, followed by the no shutdown command to recover.

Workaround: None.

  • CSCdt01582

Symptom: On Cisco IOS Release 12.0(10)W5(18b), when the module with c8510-ACL is in the Catalyst 5500 chassis, the show hardware command does not show the ACL daughter card.

Workaround: None.

  • CSCds86520

Symptom: While sending traffic with super CAM (for example, the OC48 combo super CAM or OC12 super CAM) and enabling the online diags, then performing an OIR of the super CAM. If you use shutdown and no shutdown commands on one of the interfaces you might see the following error message:

ALIGN-3-READEXCEPTION messages. 

Workaround: None.

  • CSCds85282

Symptom: In the Cisco IOS release image ls1010-wp-mz.120-13.W5.19, the LS1010 power on diagnostic test causes the IOS not to boot while the ATM router module and Fast Ethernet modules are installed.

Workaround: Upgrade to Cisco IOS release image version ls1010-wp-mz.120-13.W5.19a.

  • CSCds81263

Symptom: The IP CEF adjacencies are reported as invalid when using the ATM router module configured with LANE clients on the Catalyst 8540 MSR. The router reports an invalid cached adjacency for ip addresses that is not reachable through the LANE interface when running the show ip cef ip address command.

For example:

show ip cef 207.18.18.0
 207.18.18.0/24, version 25, cached adjacency to ATM11/0/0.1
 0 packets, 0 bytes
   via 207.18.19.1, ATM11/0/0.1, 0 dependencies
     next hop 207.18.19.1, ATM11/0/0.1
     invalid cached adjacency

With an invalid cache adjacency, all the packets destined to this address will be sent to the route processor for processing.

The CEF adjacency will be invalid until a LANE data direct VC and valid LE-ARP entry are established on the adjacent device. As soon as the data direct VC and LE-ARP entry are established, the adjacency will be reported as valid.

Workaround: None.

  • CSCds78385

Symptom: When using the Internetwork Packet Exchange (IPX), the output of the traceroute command skips the middle hop when the middle router is a Catalyst 8540/8510 MSR, Catalyst 8540/8510 CSR, or LightStream 1010.

Workaround: None.

  • CSCds77275

Symptom: On the LightStream 1010 switch, very intermittently, a SVC call could be rejected due to a VPI/VCI collision when established the call is through a PVP tunnel.

Workaround: After you reseat the interface module on which the PVP tunnel is configured, the condition will be cleared for some time.

  • CSCds69507

Symptom: If the HSRP has been configured on a Catalyst 8500 running an Cisco IOS Release 12.0(10)W5(18c), and the ATM router module is removed and then reinserted, the HSRP configuration is lost.

Workaround: None.

  • CSCds57646

Symptom: When a ping command is entered from one member of a BVI to the outside, it causes some pings between members of the BVI to timeout.

Workaround: None.

  • CSCds44008

Symptom: Under certain conditions, the Catalyst 8510 does not have a certain MAC address in the CAM table. This leads to flooding of L2 traffic for a short time, until the MAC addresses are learned.

Workaround: Issue a clear br gr command.

  • CSCds40925

Symptom: When entering the show atm interface traffic command on an ATM subinterface, the total number of cells that has passed might show as zero. This rate is incorrect.

Workaround: None.

  • CSCds28912

Symptom: IP traffic is not sent over a PVC if aal5mux encapsulation is used on a point-to-point subinterface on the Catalyst 8540 MSR. If the deb atm errors command is enabled, the following error messages will appear:

point-to-point interface does not have a VCD

Workaround: None.

  • CSCds27586

Symptom: The subinterfaces of an ATM router module (ATM router module or Enhanced ATM router module) may appear to receive the INARP packets even though the main interface is shut down. The upper layer finally discards the packet based on the state of the interface. There is no impact to any functionality.

Workaround: None.

  • CSCds08237

Symptom: The hierarchical VP tunnel configuration fails on a WAI-OC3-1S3M mixed mode port adapter module when it is in slot 0 subslot 1 of the C85MS-SCAM-2P carrier module. Slot 0 subslot 0 of the carrier module can either be empty or have another card in it, and hierarchical VP tunnel configuration will still fail. However, if the mixed mode port adapter is inserted in slot 0 subslot 0 of the carrier module, then the hierarchical VP tunnel can be configured.

Workaround: None.

  • CSCdr86285

Symptom: The output of the EXEC command show atm controllers atm 2/0/0 is incorrect. Interfaces with spurious card/subcard/port IDs are displayed, duplicating valid interface displays.

Workaround: None.

  • CSCdr79972

Symptom: The ATM router module always signals a fixed value for the PCR if LANE is configured on the ATM router module. The hidden CLI will give a way to signal the user-configured PCR. This will help with ATM traffic shaping/policing by the ATM nodes in between.

Workaround: None.

  • CSCdr70086

Symptom: The IP adjacencies are not being cleared from the gigabit ethernet card quickly. The sh epc&n
