Note All information pertains to both the Catalyst 8510 and LightStream 1010 ATM switch platforms, unless differences between the platforms are noted in the text.

This document includes the following sections:

Introduction

The Catalyst 8510 and LightStream 1010 ATM switch provide switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

The Catalyst 8510 CSR belongs to a class of high-performance Layer 3 switch routers. It is optimized for the campus LAN or intranet and provide both wirespeed Ethernet routing and switching services.

Note The ATM switch processors (hardware version 4.0 or higher) and all port adapters can be installed in the Catalyst 5500 switch chassis.

Memory Requirements

Catalyst 8510 MSR and LightStream 1010

The DRAM memory configuration is 64-MB DRAM (MEM-ASP64M), which is the default for both the Catalyst 8510 and the LightStream 1010 ATM switch platforms.

Catalyst 8510 CSR

Table 1 lists the default Flash and DRAM memory for the Catalyst 8510 CSR, as well as memory upgrade options.

Table 1 Catalyst 8500 CSR Default Memory and Upgrade Options

Memory Type	Catalyst 8510 CSR Defaults	Upgrade Options
Flash memory	16 MB	MEM-ASP-FLC16M= MEM-ASP-FLC20M=
DRAM	64 MB	None

To download and store a copy of the Catalyst 8510 CSR software image, we recommend using a minimum 20 MB Flash PC Card, which will allow you to have two or more images installed at the same time.

The Catalyst 8510 CSR boots from its onboard Flash memory by default. To change this default to boot from a Flash PC Card instead, you must change the configuration register setting to 0x2102. Refer to the Layer 3 Switching Software Feature and Configuration Guide for more information.

Hardware Supported

Table 2 lists the interfaces supported by both the Cisco IOS Release 12.0(20)W5(24) and the Catalyst 8510 MSR and LightStream 1010 ATM switch and their minimum software release requirements. All platform specific requirements are noted in the table. Table 3 lists this information for the Catalyst 8510 CSR.

Note Although minimum software versions are listed, we strongly recommend that you use the latest available software release for all Catalyst 8510 and LightStream 1010 hardware.

Caveat Symptoms and Workarounds

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 seen occasionally due to CRC errors. These discards happen even without passing traffic.
CSCdw36579

Symptom: OIR of port adapters does not work as expected using 12.0 mainline software on the LightStream 1010.

Workaround: Use the latest W5 image or do not OIR the port adapters individually. OIR the carrier module, remove the port adapter and then reinstall the carrier module.

CSCdw33641

Symptom: The console might hang if you use the hw-module subslot x/y reset command on the Framerelay E1 port adapter.

Workaround: Shutdown all the controllers in the port adapter before issuing the hw-module subslot x/y reset command

CSCdw27916

Symptom: Rate scheduling is the only scheduling algorithm used for CBR PCR. When use the show atm interface atm x/x/x command, CBR shows up as using WRR queue C2 instead of C1.

Workaround: None.

CSCdw27572

Symptom: A LightStream1010 running 12.0(19)W5(23) might show an alignment error.

Workaround: None.

CSCdw15274

Symptom: A high number of cells stuck in the memory buffer causes the CPU to miss the periodic poll of a certain module or interface, leading to a port stuck message. Occurrences are random and there is no predetermined sequence of events that causes this to happen. On an initial diagnosis, it appears to be traffic related.

Workaround: None.

CSCdv70086

Symptom: A Catalyst 8510 CSR might produce power supply error messages when writing to the bootflash:

 kockopes#copy slot0:cat8510c-in-mz_120-18_W5_22.bin bootflash:

Destination filename [cat8510c-in-mz_120-18_W5_22.bin]? CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

00:08:40: %CI-6-PSOK: Power supply 1 OKCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

Workaround: None.

CSCdv63139

Symptom: A Catalyst 8500 switch rejects SVC video calls. After first video call is built, all other video calls are rejected, and a message similar to the following is generated when a debug atm sig-all atm x/y/z command is entered:

 ATMSIG(0/0/0:11 11,35 - 0023/00):

 (vcnum:0) building cause code - cause = (0x23)requested VPCI/VCI not available, IE_cause = (0x23)requested VPCI/VCI not available, location = Private Network 1d02h: ATMSIG(0/0/0:11 11,35 - 0023/00):

 (vcnum:0) Output Release Complete msg, Call Initiated(N1) state 1d02h: SIG->CC: Svc Event Release Completed, State Dead 1d02h:

 ATMSIG(0/0/0:11 11,35 - 0023/00): (vcnum:0) Call Initiated(N1) -> Dead

Workaround: Upgrade the 8500 switches to Cisco IOS Release 12.1(7a)EY.

CSCdv25341

Symptom: A Catalyst 8540 MSR and Catalyst 8510 MSR connected via 8-port inverse multiplexing over ATM (IMA) port adapter modules change clocking configuration after the T1 interfaces bounce, resulting in a loss of synchronous clocking over the T1 IMA links. If synchronous clocking is required for circuit emulation service (CES), the CES circuit might report overruns or underruns.

Workaround: The Catalyst 8540 MSR and Catalyst 8510 MSR can be reloaded to return the clocking configuration to the original values. The T1 interfaces can be removed from the IMA group, and then can be added back and bounced. The txtiming values under the show controllers will change back to 0x2 and synchronous clocking is restored.

CSCdv22655

Symptom: The error message:

 %OIR-3-LONGSTALL: Long bus stall (20000 s), the new PAM may not seated properly, Please remove it and try again

does not specify the offending CAM/or port adapter module.

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.

CSCdv15245

Symptom: When Frame Relay ATM Soft-VC is set up in Frame Relay/ATM Network Interworking (FRF.5), the usage parameter control (UPC) on the passive side always sets to PASS, irrespective of the setting on the serial interface that is set by entering 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 entering the show vc int serial command always shows the UPC intent as PASS.

Workaround: None.

CSCdv09975

Symptom: When the shutdown/no shutdown command sequence is entered for a port in a CES card, a burst of bit errors can be observed on the circuit on some other port of the same port adapter.

Workaround: None.

CSCdv08899

Symptom: On the Catalyst 8540 MSR and LightStream 1010 platforms, the option to set loop timing on OC-12 ports is not available.

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 SNMP get operations.

Workaround: None.

CSCdv05916

Symptom: When an E1 IMA (inverse multiplexing over ATM) adapter is inserted into a chassis in which several other IMA adapters have already been added, the clock cannot be derived from the network.

Workaround: None.

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.

CSCdu77737

Symptom: A Catalyst 8510 reloads by bus error.

Workaround: None.

CSCdu74491

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

 Jul 14 02:48:23: %ATMSIG-3-FAILXCONN: Xconnect failed, xconn fail -Traceback= 6054A204 6054C0A0 60556188 60545538 6054561C 6009930C 600992F8 Jul 14 02:48:23: ATMSIG(9/1/0:0 0,78 - 0209/62): (vcnum:0) XConnected failed To Jul 14 02:48:23: ATMSIG(ATM13/0/0 0,64 - 0018/62): (vcnum:64) Jul 14 02:48:23: ATMSIG: CONNECTION MANAGER/CAC Xconn install request Port A - (9/1/0) : 0 vpi = 0; vci = 78 Port B - (13/0/0) : 0 vpi = 0; vci = 64; new vpi = 0; new vci = 64 existing vpi/vci for leg B Jul 14 02:48:23: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL

Workaround: None.

CSCdu69809

Symptom: A port of a 4-port DS3 port adaptor for the LightStream 1010 and the Catalyst 8540 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. This symptom occurs only on the Catalyst 8540 MSR and LightStream 1010.

Workaround: None.

CSCdu65431

Symptom: If the ASP or 8515 MSRP installed in a Catalyst 5500 is OIR removed from the chassis, an installed OC-12 single-mode intermediate reach port adapter continues to send the cells on the OC-12 interface. The result is that the interface of an ATM device connected to this interface will continue to report an up/up state even though the interface is reporting constant errors. This affects all Cisco IOS versions for the 8510 MSR and LightStream 1010. The port adapters with the part numbers WAI-OC12-1SSLR= and WAI-OC12-1MM= do not exhibit this problem.

Workaround: None.

CSCdu57105

Symptom: When using Cisco IOS Release 12.0(16)W5.21, a system crash with a bus error at imapam_mmcport_init occurs after the creation of the 131st interface.

Workaround: Remove any unused modules from the chassis so that additional virtual interfaces can be created.

CSCdu56774

Symptom: 4-path load balancing is missing for Ethernet processor interfaces.

Workaround: None.

CSCdu55104

Symptom: After an online insertion and removal (OIR) of a carrier module in the 8540 MSR, the input/output packet counters for the corresponding interfaces show incorrect values.

Workaround: Do not perform OIRs, or clear the counters on that interface.

CSCdu37838

Symptom: The spanning tree protocol of a bridge-group cannot be changed.

Workaround: Deconfigure the bridge-group and then reconfigure it with a different spanning tree protocol.

CSCdu35316

Symptom: When a user specifies a Soft PVP configured as VBR-NRT Service category in the ingress port, the service category at the egress interface of that switch is seen as UBR rather than VBR_NRT.

Workaround: None.

CSCdu26719

Symptom: A Catalyst 85xx running Cisco IOS Release 12.0(13)W5(19c) experiences high multiservice route processor utilization when Internetwork Packet Exchange (IPX) networks are added to Bridge Group Virtual Interface (BVI) interfaces; as more IPX networks are added, multiservice route processor utilization increases.

Workaround: If configuring bridging over ATM router module subinterfaces, configure a map-list for the bridged virtual circuit, using the keyword "bridge".

For example:

      interface ATM3/0/0.50 multipoint

         no ip directed-broadcast

         map-group b50

         atm pvc 2 50 pd on interface ATM0/0/0 1 50

         bridge-group 50

      map-list b50

         bridge atm-vc 50 broadcast

CSCdu24272

Symptom: On ATM switches, the loopback IP address is not exchanged during ILMI negotiation with the neighboring switches. Consequently, the output of the show atm ilmi-status command indicates 0.0.0.0 as the peer IP address, even though a loopback address is configured.

Workaround: Configure the IP address on an Ethernet interface.

CSCdu20618

Symptom: One side of a circuit emulation service (CES) E1 port of a LightStream 1010 switch connection remains consistently in the YELLOW alarm or ALARM INTEGRATION state.

Workaround: None.

CSCdu16973

Symptom: When running cell-mode MPLS on a network of switch routers with redundant paths, conversion to MPLS after a routing change might take up to 4.5 minutes. OSPS converges normally.

Workaround: None.

CSCdu10985

Symptom: An ARM interface might not bridge between ATM and the native VLAN.

Workaround: Configure some other non-functional VLAN as native.

CSCdu09850

Symptom: On a Catalyst 8540 performing an ATM-Frame Relay internetworking function, the ATM-Frame Relay does not propagate when the Local Management Interface (LMI) indicates a permanent virtual connection (PVC) as inactive.

Workaround: None.

CSCdu07640

Symptom: The no ip route-cache cef command might disappear from the running configuration of the BVI interface after reloading the switch router.

Workaround: None.

CSCdu04045

Symptom: The entry for atmSoftPVccRetryThreshold feature has an incorrect default value of 0, rather than the correct default value of 1 that is shown in the ATM Soft PVC Management Information Base (MIB). A value of zero indicates that an infinite number of call attempts are required to increment the atmSoftPvcCallFailures object and thus disables alarms for the Soft PVCC.

Workaround: Set the atmSoftPVccRetryThreshold value to 1.

CSCdu03975

Symptom: There is a noise problem with the CES PAM hardware version one.

Workaround: None.

CSCdu02569

Symptom: When slot 0 is configured as the ARP client, the client might release the SVC within one minute of a ping.

Workaround : Use the subinterfaces of slot 0 as the ARP client instead.

CSCdt93866

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.

CSCdt91430

Symptom: Under a heavy load the switch router might misorder cells going out OC12 port adapter modules.

Workaround: Use the four-port OC12 modules designed for the Catalyst.

CSCdt91339

Symptom: Attempts to create multipoint connections via the atmVcCrossConnectTable in the ATM Management Information Base (MIB) are unsuccessful.

Workaround: None.

CSCdt86157

Symptom: The SNMP polling of the MIB object atmVplOperstatus (in Virtual Path MIB) for VP tunnels shows that the VPL is DOWN, even when the tunnel is UP (as shown by the CLI).

Workaround: None.

CSCdt85859

Symptom: In bridging, the aging time of ethernet process interfaces is always set 300 seconds, despite what it is configured for.

Workaround: None.

CSCdt81270

Symptom: The one-Port OC12 port adapter module might cause cell corruption. This will inevitably lead to packet corruption wherever segmentation and reassembly is performed to put the cells back into frames.

Workaround: None.

CSCdt80934

Symptom: When a static route is added to and deleted from an interface that already has a static route connected to it, the packets are process-switched.

Workaround: Enter the clear ip route command.

CSCdt78847

Symptom: On PVCs on a VP tunnel, attempts to configure usage parameter control (UPC) values other than "pass" might not succeed.

Workaround: Do not define the VP tunnel, just configure PVCs on the VPI.

CSCdt78491

Symptom: Online Diagnostic Snake tests might send ILMI traps when an interface becomes active. This can cause clients on other inter-faces to reset ILMI.

Workaround: Disable the snake test by entering the no diagnostics online snake command in global configuration mode.

CSCdt73634

Symptom: Cell memory might get stuck when ABR, IMA, and hierarchical VPs are combined.

Workaround: Enter the shutdown command on the IMA interface. Take the first link on the IMA interface out of IMA group. Enter the no shutdown command followed by the shutdown command on the interface. Enter the no shutdown command on the IMA interface.

CSCdt71010

Symptom: ifTable Indexes might not match MIB-II table indexes.

Workaround: None.

CSCdt70190

Symptom: If a switch processor switch over occurs, the IMA interface will remain in a waiting state. After this, entering the shutdown command and then the no shutdown command on the IMA interface will bring it to the "going down" state.

Workaround: To avoid this issue, disable online diagnostics before a switch processor switch over.

CSCdt67260

Symptom: The switch router might crash when being polled by SNMP.

Workaround: None.

CSCdt62555

Symptom: When using PNNI, another vendor's equipment might send an invalid PTSE update. If the switch router receives one of these invalid updates, the PNNI neighborship might not re-establish.

Workaround: None.

CSCdt62368

Symptom: On Catalyst 5500 switches, the fabric integration module (FIM) loses ILMI prefix when more than 30 LANE clients that are configured on the FIM go down. The FIM eventually recovers the same ILMI prefix.

Workaround: None.

CSCdt62215

Symptom: After resetting an E1 device connected to the CES port there might not be connectivity about Layer one.

Workaround: Enter the shutdown command followed by the no shutdown command on the CBR interface.

CSCdt56793

Symptom: The Puma Driver might not update the ingress/egress heartbeat register pointers. Because of this, it might not poll these registers to monitor the ingress/egress health. In cases where the firmware crashes, it might not immediately detect the failure.

Workaround: None.

CSCdt49005

Symptom: SVC signalling across a VP tunnel might not work after a reload.

Workaround: None.

CSCdt47944

Symptom: When configuring Frame Relay Connection Traffic Table rows, if the values specified for traffic parameters PIR and BC are close to the maximum allowed, the MBS value computed for their corresponding ATM traffic table row might be incorrect.

Workaround: None.

CSCdt47492

Symptom: On the OC-3c port adapter module, ILMI might remain in the "waitdevtype" state after a redundancy fail over.

Workaround: If the problem is seen on port 1-3, bring up port 0. If the problem is seen on port 5-7, bring up port 4. If the problem is seen on port 9-11, bring up port 8. If the problem is seen on port 14-15, bring up port 12. The port can be brought up by connecting a loopback cable, or just by using that port.

CSCdt46026

Symptom: A switch router with OC3 port adapters and five Fast Ethernet interface modules might boot up with the following error message:

 epif_aal5_fastsend: bad vcinfo This message may appear 100s

 of times and slow down the boot process. Normal operation does not seem affected

 once the 8500 has finished booting.

Workaround: None.

CSCdt44930

Symptom: When a switch router sends a tag distribution protocol (TDP) bind request and does not receive an answer, the TVC remains unconnected. This might cause scalability problems in large networks because over time these TVCs might use up a large number of resources.

Workaround: Add a timer to clean up the VCs.

CSCdt40530

Symptom: Switch routers running Cisco IOS Release 12.0(13)W5(19) or earlier might experience a memory leak when used with an NMS (Network Management System) running SNMP whenever it accesses PNNI tables.

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

CSCdt24278

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

Workaround: None.

CSCdt22167

Symptom: When a significant amount of traffic is pumped in an egress direction, it exhausts the resources on the data buffers in the egress direction, and a cell backlog occurs on the switching fabric. This results in periodic poll messages being sent to the firmware, declaring the firmware to be dead.

Workaround: Issue a shutdown/no shutdown command on the interface module or OIR the interface module.

CSCdt18467

Symptom: The port stuck message might log to the system log.

Workaround: None.

CSCdt15978

Symptom: The telnet response over an ISL trunk might be very slow. This is because small ISL frames (under 94 bytes) are not padded, and some devices drop ISL frames that are smaller than 94 bytes.

Workaround: None.

CSCdt15931

Symptom: System reloads are observed on the ATM switch processor that is running Cisco IOS Release 12.0(13)WA(19a). Reloads occur only on the Cisco Catalyst 5500 series switches that incorporate the WS-X5165 fabric integration module (FIM).

The following error message will occur:

 %ALIGN-1-FATAL: Illegal access to a low address

 *** System received a Bus Error exception ***

All other 12.0(X)W5(X) images will function normally with the WS-X5165 (FIM) installed.

Workaround: Update to Cisco IOS release 12.0(13)W5(19b).

CSCdt10494

Symptom: An ATM router module interface indicates outgoing packets when that interface is administratively down.

Workaround: None. This does not impact functionality.

CSCdt13517

Symptom: The switch router might stop switching some VCs and log error messages like the following:

 12:37:34.793: ATMSIG(12/1/0:0 0,37 - 274610/00): (vcnum:0) XConnected failed To Jan 9 12:37:34.793: ATMSIG(12/0/1:0 0,268 - 398903/00): (vcnum:0) Jan 9 12:37:34.793: ATMSIG: CONNECTION MANAGER/CAC Xconn install request Port A - (12/1/0) : 0 vpi = 0; vci = 37 Port B - (12/0/1) : 0 vpi = 0; vci = 268; new vpi = 0; new vci = 268 existing vpi/vci for leg B Jan 9 12:37:34.793: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL

Workaround: Reload the switch router.

CSCdt10494

Symptom: An ARM interface might indicate outgoing packets when that interface is administratively down. This does not impact functionality.

Workaround: None.

CSCdt10434

Symptom: When there is a lot of signaling svc setup and teardown on an nni tunnel, interface calls might fail with a vpi/vci collision.

Workaround: Use a regular interface (no tunnels).

CSCdt05674

Symptom: Continuous messages that state the port is dead, followed by a series of continuous tracebacks, will appear on the LightStream 1010 ATM switch. This occurs when the switch has an FC-PCQ feature card that has a lot of connections or a lot of LANE traffic running through it, and will display these messages when an interface carrying most of that traffic is shut down at the peer switch.

Workaround: Update to Cisco IOS Release 12.0(13)W5(19c).

CSCdt04356

Symptom: On a switch router performing the Frame Relay/ATM Network Internetworking function, when the Local Management Interface (LMI) indicates a PVC is inactive on an NNI interface, this information is not propagated by the Frame Relay/ATM software.

Workaround: None.

CSCdt00616

Symptom: The atm ds4-scramble command might not program the PHY chip in the scrambling mode. This causes data loss if the other end is in scrambling mode.

Workaround: Disable scrambling at the other end.

CSCds85282

Symptom: Power-on diagnostics hang, and the IOS is unable to boot, when ARM, Fast Ethernet, and OC-12 cards are all installed in the same chassis.

Workaround: None.

CSCds78385

Symptom: IPX traceroute might skip the middle hop when the middle router is the Catalyst 8540 switch router.

Workaround: None.

CSCds69507

Symptom: When an OIR is performed on an ARM module, the HSRP configuration might get lost.

Workaround: None.

CSCds57303

Symptom: The ATM User-Network Interface (UNI) does not include a cumulative round-trip time parameter in the ABR call setup. This situation might cause interoperability issues with different vendor products.

Workaround: None.

CSCds55768

Symptom: In multi-vendor environment, if the IMA side of another company's product does not support the test pattern specified in Inverse Multiplexing for ATM (IMA) Specification Version 1.1 by the ATM Forum, the Cisco IMA interface does not function.

Workaround: None.

CSCds51590

Symptom: The OAM configuration for a frame-relay PVC is not preserved across the reload. If an OAM AIS/RDI is enabled on the ATM interface that carries a frame-relay PVC from a 1CT3 serial interface, and the system is reloaded with this saved configuration, the OAM is no longer enabled on the frame-relay PVCs.

Workaround: Update to Cisco IOS Release 12.0(13)W5(19c).

CSCds51004

Symptom: The circuit emulation service (CES) address does not change when the switch router address is changed. When the global switch ATM address prefixes are added or deleted (via the atm address command), addresses registered for existing CES circuits are not changed.

Workaround: None.

CSCds44008

MAC address is not present in the CAM table on bridging tests.

Symptom: Under certain conditions, a Catalyst 8510 CSR might not have a certain MAC address in the CAM table. This would lead to flooding of Layer 2 traffic for a short time until the MAC addresses are learned.

Workaround: Issue clear bridge group command.

CSCds43859

Symptom: Although packets are being sent out from an ATM OC-12 interface module, the 5-minute output rate shown using the show interface atm command indicates 0 bits/sec output. This is not consistent with the output rate shown under the show atm traffic command.

Workaround: None.

CSCds40925

Symptom: When the show atm interface traffic command is entered on a subinterface, the total number of cells that has passed might show incorrectly as zero.

Workaround: None.

CSCds39855

Symptom: When the primary clock source is in the "unlockable"' state, and the clock fails over to the secondary clock, the router never reverts to the primary clock source, even when the connection is clean and the clock source is present.

Workaround: None.

CSCds38890

Symptom: The present configuration does not work properly for frame reject (FRMR) and acknowledgement timeout messages. Occasionally a file transfer works normally, but most of the time it does not.

Workaround: None.

CSCds37204

Symptom: Under heavy traffic conditions, the switch router might not respond to the Marconi switch poll in a timely manner, and the Integrated Local Management Interface (ILMI) signaling and Service-Specific Connection-Oriented Protocol (SSCOP) signaling restart, and all virtual circuits are torn down.

Workaround: None.

CSCds33901

Symptom: When the reset button is pushed, the switch router might not boot the main-image, and eventually goes into ROMMON.

Workaround: None.

CSCds35355

Symptom: A switch router running SNMP might have massive memory failures. SNMP might consume all memory and it will appear to be fragmented.

Workaround: None.

CSCds29865

Symptom: When HSRP is configured on the eight-port Gigabit Ethernet interface module, HSRP connectivity might be disrupted after a remote link failure is followed by a link restoration.

Workaround: Configure another HSRP group with a higher number and move the standby configuration to that group.

CSCds28912

Symptom: IP traffic is not sent over a PVC if AAL5 MUX 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.

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 pam is inserted in slot 0 subslot 0 of the carrier module, then the hierarchical VP tunnel can be configured.

Workaround: None.

CSCds07238

Symptom: 64-bit octet counters might not be supported in the ifXTable.

Workaround: None.

CSCds04747

The switch router might be vulnerable to the successful prediction of TCP Initial Sequence Numbers.

Symptom: The switch router might be vulnerable to the successful prediction of TCP Initial Sequence Numbers. This vulnerability only applies to the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device, in transit between two other hosts.

Workaround: Update to Cisco IOS Release 12.0(13)W5(19c).

CSCds00513

Symptom: When serial interfaces on a Frame Relay/ATM internetworking port adapter are oversubscribed, and significant data bursts occur simultaneously on multiple VCs on multiple serial interfaces, one serial interface might get stuck.

Workaround: Enter the hw-module
