Note All information pertains to both the Catalyst 8510 and LightStream 1010 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 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.

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

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

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 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 Catalyst 8510 MSR and LightStream 1010 switch and Cisco IOS Release 12.1(6)EY 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

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

CSCdu03779

A route might not be distributed over the BVI/portchannel/dot1q.

Symptom: On an 8-port Gigabit Ethernet interface card, a route might not be distributed over the BVI/portchannel/dot1q.

Workaround: Save the configuration and reload the switch.

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.

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.

CSCdt93289

An error message might occur when configuring HSRP over BGI.

Symptom: When configuring HSRP over BGI, you might get the following message at regular intervals:

 Getting "%STANDBY-3-DUPADDR: Duplicate address "

Workaround : On the BVI, enter the shutdown command and then enter the no shutdown command on the BVI or reload.

CSCdt71010

The ifTable Indexes might not match the MIB-II table indexes.

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

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.

CSCdt43218

Symptom: The IP PAT tree becomes programmed incorrectly for 1483 SVC after removing the ARM card. If an SVC is configured on an ARM/ARM2 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 ARM/ARM2 card, remove any sub-interfaces that have a SVC configurations, then proceed to do the OIR.

CSCdt40530

A memory leak might occur.

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 ARM 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 ARM1 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 ARM1 interfaces, while two Catalyst 8540 MSRs are connected.

This has no functionality impact.

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.

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.

CSCdt11569

Symptom: Oversized packets on the ARM2 interface are observed when it is a member of a BVI. This console output relates to the oversized packets on the ARM2 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 ARM (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 ARM. Frame interfaces or non-LANE interfaces on ARM with configured PVC's 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:

 ../-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 ARM 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.

 -Process= "ATM ARP INPUT", ipl= 0, pid= 30

 -Traceback= 600CE1BC 600CF2A4 60792B0C 60796850 60797744 600BBA64 600BBA50shut

 0x600BBA50:r4k_process_dispatch(0x600bba50)+0x0

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.

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 ARM 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 ARM 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: IPX traceroute is skipping the middle hop when the middle router is a Catalyst 8540 CSR/MSR; all IPX packets are cut-through switched and not given to the route processor.

Workaround: None.

CSCds69507

Symptom: If the HSRP has been configured on a Catalyst 8500 running an Cisco IOS Release 12.0(10)W5(18c), and the ARM 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

Incorrect traffic statistics might display.

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.

CSCds27586

Symptom: The sub-interfaces of an ARM (ARM1 or 2) 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.

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 ARM always signals a fixed value for the PCR if LANE is configured on the ARM. 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 ip-address command was issued on the adjacency, it was found that the entry for the host on vlan2 was still there and took some time to clear. As soon as it did clear, the ping command works again.

Workaround: None.

CSCdr62898

Symptom: Per-VC drop counters are not consistent. This applies only to non-packet discard connections. The inconsistencies are between the three per-VC statistics: total RX cell drops, RX UPC violations, and RX clp0 q full drops. The total of RX UPC violations and RX Clp0 q full drops exceeds the total RX cell drops count. However, the total RX cell drops is accurate.

Workaround: None.

CSCdr43326

Symptom: The atmVcCrossConnectAdminStatus entries might disappear.

Workaround: None.

CSCdr36952

Symptom: The switch router will crash and hang when ip http server is configured and a browser connects to http://<router-ip>/%%. This defect can be exploited to produce a denial of service (DoS) attack. This information has been announced on public Internet mailing lists which are widely read by both security professionals and by security "crackers," and should be considered public information.

Workaround: Disable the IP http server with the following command: no ip http server
Alternatively, the administrator can block port 80 connections to the switch router via access lists or other firewall methods. For further information, refer to the security advisory available at http://www.cisco.com/warp/public/707/advisory.html.

CSCdr35301

Symptom: ifOutOctets wrapping at 3000000 on an ATM interface.

Workaround: None.

CSCdr32958

Symptom: CPU hog by OIR handler.

Workaround: None.

CSCdr30421

Symptom: Multicast stats shows an incorrect rate in kbps.

Workaround: None.

CSCdr28797

Symptom: HVPT: Incorrect scheduling values installed for low PCR. When a HVPT with a PCR of 2 kbps is configured on a OC-3 interface, this results in the cell starving of WKVC on the main interface.

Workaround: None.

CSCdr02365

Symptom: The output from the show bridge commands are incomplete.

Workaround: None.

CSCdr01726

Symptom: The ILMI status of shaped and hierarchical tunnel subinterfaces that are down (not shutdown) appear stuck in the Restarting state after a shutdown/no shutdown command sequence.

Workaround: None.

CSCdp80826

Symptom: OAM F5 loopback cells are not passing across 25-Mbps port adapter interfaces.

Workaround: Configure the global configuration command no atm oam intercept end-to-end on the switch.

CSCdp79109

Symptom: The switch might have spurious memory access tags after configuring and unconfiguring tag switching on different ATM interfaces. This is not known to impact tag switching functionality on the switch. The following message might appear on the console:

 *** gd03_tag_stress: Mon Jan 31 08:35:12 2000 949336512 comment Spurious

 memory accesses on gd03_r55_11: count = 1 ***

 *** gd03_tag_stress: Mon Jan 31 08:35:12 2000 949336512 comment 1C

 1 0x60254C28 0x60236140 0x6009868C 0x60098678

Workaround: None.

CSCdp50167

Symptom: IMA group fails to come up intermittently, especially after reload and on E1 IMA links.

Workaround: Go to one of the IMA interfaces and give the following command:

 Switch(config-if)# fwmon "altrap 00 ff 00 ff 00 ff"

If the group still remains down, it indicates a persisting alarm on the line. The line configuration has to be checked to clear the problem.

CSCdp20865

Symptom: Performing a shutdown/no shutdown command sequence on an ARM interface, especially when it has configured a large number of LANE clients, might cause an error message like this to appear:

%LANE-3-LANE_ERROR: lecs finder: ILMI hung on interface ATM1/0/0

It indicates an internal timeout occurred. It should try to self-cover and not affect any normal operations.

Workaround: None.

CSCdp14004

Symptom: In rare instances, the switch might force crash at a program counter value of 0x6004A4D64.

Workaround: None.

CSCdp02816

Symptom: The show ncdp path root command might not display any information when you access the switch through the Ethernet port.

Workaround: Access the switch using the console port.

CSCdm80628

Symptom: A T1 CES interface does not send out a remote alarm indication (RAI) in the reverse direction upon detecting an alarm indication signal (AIS).

Workaround: None.

CSCdm36800

Symptom: The CES ABCD bits are not user configurable when a fault occurs.

Workaround: None.

CSCdk73733

Symptom: Power-on diagnostics will display an NVRAM-Config failure following the second power-cycle after you use the write erase command if the write memory command has not been used between power-cycles.

This failure will occur only if you use the write erase command and the power-on diagnostics runs twice without the write memory command being used.

Note Power-on diagnostics run only if the switch is powered on. Power-on diagnostics do not run when using the reload command.

Workaround: After using the write erase command, use the write memory command before power cycling the switch.

CSCdk57536

Symptom: The following message appears on the neighbor ATM switch after using the reload command:

%SYS-3-CPUHOG: Task ran for 3984 msec (24/11), process = Net Background

Workaround: None.

CSCdk56557

Symptom: Spurious memory access on show ip route command when SONICT interface is shutdown.

If you shutdown a 10-Mbps port and then use the show ip route command, spurious memory access appears in the print_route_preamble():

Workaround: None.

CSCdk52436

Symptom: On a switch router configured with 32 MB RAM, IPC traffic between the port adapter driver and the firmware can experience a transient failure when the port adapter firmware crashes under heavy traffic conditions. The port adapter recovers from this transient failure if it is reset after waiting for about 2 minutes.

This IPC failure, which is due to an unexpected firmware crash under a heavy load, does not occur on a system configured with 64MB of RAM.

Workaround: None.

CSCdk47516

Symptom: Tag switching and Tag Discovery Protocol (TDP) memory fragmentation. While running tag switching with a very large number of destinations, continuous toggling of VC Merge (which forces all the TDP sessions to restart) on the switch for a very long period of time (for example, overnight) causes memory fragmentation in the TDP process.

Workaround: None.

CSCdk42052

Symptom: When loading a software image version 11.3 or later on a switch router with a software image version 11.2 or earlier, LEC and other LANE components might fail to come up if they are configured using an ATM address whose first 19 bytes are the same as the active ATM address of the switch.

The ATM address of the switch along with the first 128 values for its selector byte should be reserved for use by PNNI. Starting with the 11.3 software version, PNNI supports hierarchy and registers an ATM address for all PNNI nodes using the switch ATM address with various selector byte values.

Workaround: If LANE components fail to come up because their ATM addresses conflict with the reserved ATM addresses for PNNI, reconfigure the LANE components using different addresses. It is recommended that LANE applications use the addresses shown by the show lane default-atm-addresses command, which eliminates this problem.

CSCdk41001

Symptom: The show controller atm card/subcard/port command displays the incorrect interface type after hot swapping the port adapter.

Workaround: None.

CSCdk25256

Symptom: A non-zero generic flow control (GFC) field is not reset to zero when passing through the switch router.

When cells with a non-zero GFC field are received on a PVC, they are switched on the exit port without changing the GFC field. The switch should reset to zero all GFC bits from cells received with non-zero GFC at the user network interface (UNI).

Workaround: None.

CSCdk10398

Symptom: ILMI does not come up upon reload of VP-MUX (VUNI).

ILMI on the tunnel interface, which is connected to the far end peer device through a VP-MUX switch and virtual UNI, is occasionally unable to come up and stay in state of "WaitDevType" after reloading the VP-MUX switch. This situation can be cleared by shutting down the tunnel interface, disabling ILMI followed by a no shutdown command on the tunnel interface. After the interface settles down, ILMI on the tunnel can then be reenabled by shutting down the interface, entering the atm ilmi-enable command and also the atm auto-configuration command, if desired. Reenable the tunnel interface with a no shutdown command.

Workaround: None.

CSCdk07378

Symptom: Funnel VCs can jeopardize quality of service (QoS) for services.

The current multipoint-to-point funnel implementation can compromise the QoS guarantees of other connections (guaranteed services) when the application that created the funnel SVC malfunctions. For example, if the application were to transmit traffic on more than one leg of the funnel SVC simultaneously, the rate scheduler on the output interface oversubscribes and, potentially, affects the peak cell rate (PCR), sustained cell rate (SCR), and maximum cell rate (MCR) guarantees for other VCs on the interface.

Workaround: None.

CSCdj85853

Symptom: When you set the ROM monitor environment variable boot to a nonexistent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.

Workaround: Power-cycle the switch; a break character is sent to the switch to force it to the ROM monitor prompt. You can then manually reboot the switch.

CSCdj84379

Symptom: The granularity provided by the FC-PFQ feature card scheduling hardware does not allow an exact match of all requested cell rates. To satisfy the traffic contract guarantee, the next higher available scheduling value is used. A shaped VP tunnel is used frequently to pass data to a WAN VP trunk, and limits the traffic transmission to the scheduled rate. This can cause cells to be dropped in the WAN. It might be better to do any dropping prior to multiplexing onto the VP, so that a packet discard can be performed. Packet discard cannot be performed on the VP trunk.

Workaround: None.

CSCdj82930

Symptom: Open shortest path first (OSPF) does not recognize more than four parallel interfaces. This might cause some tag switching VCs (TVCs) to not get switched to other interfaces if a tunnel carrying the TVCs is shut down.

Workaround: Enter a clear ip route command on the switch on the interface that was shut, or a clear ip route command on all the switches to bring everything back up. If the clear ip route command does not bring everything back up, enter a shutdown/no shutdown command sequence on the UNI interfaces of the switch that had the closed physical interface.

CSCdj80396

Symptom: While setting up a large number of calls, the system generates the following error message:

%SYS-3-CPUHOG: Task ran for 5852 msec (0/0), process = Exec, PC = 6008DBB4

Workaround: None.

CSCdj78305

Symptom: IP host-routing does not disable when specified.

Workaround: Enable and disable IP routing and then save the configuration to NVRAM.

CSCdj71109

Symptom: The ATM switch does not currently support maxvc-number negotiation through ILMI.

Workaround: None.

CSCdj68412

Symptom: If there are multiple parallel paths to the same destination on a switch router with a FC-PFQ feature card installed, the tag switching VCs (TVCs) should be load balanced on a per network prefix basis over these parallel paths (up to a maximum of 4 parallel paths) instead of being VC merged. Load balancing does not happen in some cases and the TVCs might be VC merge and go out of the switch as a single VC.

Workaround: None.

CSCdj54954

Symptom: On a switch router equipped with an FC-PFQ, the maximum number of cells available for use is 64,511. The number of cells in the switch fabric is 65,535.

Workaround: None.

CSCdj42967

Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up, leaving it in a releasing or inactive state.

Workaround: None.

CSCdj25772

Symptom: Cell loss might occur while hot swapping a power supply.

Workaround: None.

CSCdj18678

Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.

Workaround: None.

CSCdj18430

Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.

Workaround: None.

CSCdj13565

Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels. The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (via PortSelTable) is not possible until the interface's MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.

Workaround: None.

CSCdj10889

Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on PortSelectGroups representing the interface on which the call came in and the counters shown on the PortSelectGroups representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.

Workaround: None.

CSCdj01757

Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.

Workaround: None.

CSCdi92142

Symptom: A LECS, using Cisco IOS Version 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.

If different emulated Local Area Networks (ELANs), using Cisco IOS Release 11.1(X), are configured on multiple subinterfaces of the same physical interface, then all LESs multiplex the control messages (which validate the clients) into a single VC.

For example, see the following LES router configuration:

 atm1/0.1 sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN

 atm1/0.2 sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN

 atm1/0.3 sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN

 atm1/0.4 sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

This configuration of an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

 %LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan

 'sysa_70k_31_a1.1_LAN'

 %LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan

 'sysa_70k_31_a1.2_LAN'

 %LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan

 'sysa_70k_31_a1.3_LAN'

The clients are still allowed to join the ELAN. Disregard the warning messages.

Workaround: None.

CSCdi83275

Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

 %AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.

Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi82954

Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX LED lights up.

Workaround: None.

CSCdi75584

Symptom: Under very heavy traffic conditions the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.

Workaround: None.

CSCdi74229

Symptom: When more than 1000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

 %SYS-3-CPUHOG

This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch.

Workaround: None.

CSCdi55937

Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch.

Workaround: None.

Interoperability

Starting with the following software releases, hardware and software functionality interoperability exists between CSR interface modules and MSR interface modules by way of the ATM router module on the MSR chassis running an MSR image:

Cisco IOS Release 12.0(10)W5(18b) supports interoperability between CSR interface modules and MSR interface modules by way of the ATM router module on the Catalyst 8510 MSR running an MSR image.

Y2K Compliance

Catalyst 8510 and LightStream 1010 systems running Cisco IOS Release 12.0(0.6)W5(1) or later have been certified as Y2K Compliant. For more information, see the following URL: http://www.cisco.com/warp/public/752/2000/.
