Release Notes for the Catalyst 8510 and the LightStream 1010 Switch for Cisco IOS Release 12.1(19)E

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 provides both wirespeed Ethernet routing and switching services.

Memory Requirements

This section describes the memory requirements for the Catalyst 8510 and the LightStream 1010 switch platforms.

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 8510 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 for Cisco IOS Release 12.1(19)E 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 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.

CSCin06705

Symptom: Subinterfaces of route processor and ATM router module ports are not registered with SNMP ifTable.

Workaround: None.

CSCin37548

Symptom: The following issues could be seen on the simultaneous execution of certain PNNI CLIs.

The switch reloads when:

Through a console session run the show atm pnni topology command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session.
Through a console session run the show atm pnni neighbor command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session.
Through a console session run the show atm pnni background routes admin-weight command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session.
Through a console session run the show atm pnni exp-path detail command and wait for the more prompt to appear. Through a Telnet session delete all the explicit paths. Press the Space key on the console session.

The following issues are also seen:

Through a console session run the show atm pnni topology detail command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Pressing Space key on the console session causes spurious memory access.
Through a console session run the show atm pnni aggregation node border-detail exception-detail command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session. The output is not aborted gracefully.
Through a console session run the show atm pnni database command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session. The output is not aborted gracefully.
Through a console session run the show atm pnni explicit-paths detail command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Pressing the Space key on the console causes spurious memory access and tracebacks are seen.

Workaround: None.

CSCin36885

Symptom: On a Catalyst 8510 MSR, if an OC-3 interface is overbooked and configured with PVCs that consume more than 599 Mbps of bandwidth, during bootup these PVCs are lost from the running configuration.

The following error message appears during bootup for every PVC that is rejected.

 %connection creation fails: specified traffic/resource parameters are invalid

Workaround: Configure the PVCs that were lost once the switch boots up.

CSCin14721

Symptom: The CBR interface module sends a "remote alarm" to the peer interface if the line flaps continuously. This causes the peer interface to change to "yellow alarm" state.

Workaround: Enter the shutdown and no shutdown commands on the CBR interface.

CSCin13430

Symptom: A memory leak might occur during an "atmSoft_timerProcess". With every "soft-vc" retry the holding memory on "atmsig CC" and "atm soft CV timer" increases and the "free" memory decreases. The free memory might fall to as low as 700K at times.

Workaround: None.

CSCin12950

Symptom: Packets received with a destination multicast MAC address and destination unicast IP address, are forwarded to the Route Processor and then forwarded back out on the VLAN where the packets were received.

Workaround: None.

CSCin12417

Symptom: An ATM interface might stick in the state "going down" if the PVC is created from the ATM router module with VCI "34" on the ATM side. For example, "atm pvc 2 35 pd on interface ATM0/0/0 7 34" causes the line to flap "up" and "down".

Note The problem is not seen with any other VCI on the ATM side.

Workaround: Recreate the PVC using any VCI other than "34" on the ATM side.

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.

CSCin02864

%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.

CSCea85081

Symptom: The ATM router module might have a connectivity problem for bridged traffic. The connectivity is broken for five minutes when the Soft-VC between the ATM router modules are rerouted using another path.

Workaround: Run the clear bridge command on the Catalyst 8500 switch that is not switching traffic.

CSCea72899

Symptom: Soft PVC does not come up.

If a soft PVC originates from a LightStream 1010 switch directly connected to an Alcatel switch, the soft PVC never comes up. If the call originated from the Alcatel side, the soft PVC comes up with no problem.

Note This occurs if the LightStream 1010 switch is running Cisco IOS Release 12.0(24)W5(26b) or LightStream 1010.

For example:

At UNI ATM interface:

 atm soft-vc 1 455 dest-add xx.348f.8001.bbfc.0000.0ba0.6f10.4080.210a.2a01.00 1 455 rx-cttr 1 tx-cttr 1

Alcatel switch directly connected, ATM NNI, PNNI up and adjacency up:

When the call is initiated from the LightSteam 1010 switch, nothing comes up over to the Alcatel switch. At the same time, when the call is initiated from the Alcatel switch, the soft PVC comes up:

 Switch# show atm vc interface atm 9/1/1

Workaround: None.

CSCea66219

Symptom: A memory leak occurs in the ATMSIG processes. This is observed using the show processes memory command. The ATMSIG processes hold increasing amounts of memory and free memory is decreasing.

Note This occurs on LightStream 1010 or Catalyst 8540 switches running Cisco IOS Release 12.0(24)W5(26b), Cisco IOS Release 12.1(12c)E1, or Cisco IOS Release 12.1(13)E.

Workaround: None. The switch must be rebooted to recover.

CSCea48476

Symptom: POD fails with ATMDIAG_UNEXPECTED_PIF_INTERRUPT_ERROR.
POD (Parallel Optical Device) errors might occur in some LightStream 1010 switches.These errors occurred but the ports where the POD errors appeared were up and working. This problem appears to be a false error reported by POD.

Workaround: None.

CSCea33595

Symptom: On a LightStream 1010 switch running Cisco IOS Release version 120-24.W5.26b, the system might crash due to a system restarted by a bus error at PC 0x6063F9C8, address 0xD0D0D15.

Workaround: None.

CSCea30004

Symptom: Whenever you attempt to update the Access Control List (ACL) attached to the management interface (Ethernet2/0/0) on the LightStream 1010 ATM switch the following error message appears:

 ACL is not supported

ACL functionality on the interface is not affected.

Workaround: None.

CSCdz71298

Symptom: The Catalyst 8500 switch might display the following error messages:

 xpif_read_media_type: Null ds structure for Port-channel1

 xpif_read_media_type: Null ds structure for Port-channel1

Workaround: None.

CSCdz52991

Symptom: On the 8-port Gigabit Ethernet module, at very high traffic rates Internal buffers (vbufs) are exhausted and ASSERTION FAILED messages appear.

Workaround: None.

CSCdz41247

Symptom: PNNI adjacency between directly connected Catalyst 8500 MSR switches fails to come up using the following configuration: both switches running IOS Release 12.1(12c)EY and a Catalyst 8510 MSR connected to a Catalyst 8540 MSR over an OC3 connection. The following conditions caused the problem to appear:

1. The Catalyst 8510 MSR was upgraded from IOS Release 12.0(7)W5(15c) to IOS Release 12.1(12c)EY

Note Prior to the IOS image upgrade the PNNI adjacency worked properly.

2. The PNNI adjacency did not come up after Catalyst 8510 MSR was reloaded and power cycled and the following message appeared in the console log:

3. When the physical port was changed from ATM9/1/3 to ATM 9/1/1(on the same interface module of the Catalyst 8540 MSR) the previous error message disappeared, but PNNI did not come up as shown in the following example:

 *Nov 19 09:30:45: PNNI:72.1 Hello at ATM0/0/3: Tx, state attempt

 *Nov 19 09:30:45: NodeId: 72:160:39.036F100A000000003100C900.00053243D901.00

4. On the Catalyst 8540 MSR, 1-way PNNI adjacency was established and the following message appeared:

 Nov 21 03:25:14: PNNI:72.1 Hello at ATM9/1/1: Tx, state 1way_in

 Nov 21 03:25:14: NodeId: 72:160:39.036F100A000000003100C100.003094398501.00

Workaround: None.

CSCdz06963

Symptom: After a LAN emulation client (LEC) goes down, a router that has an enhanced ATM port adapter (PA-A3) may not be able to register a network service access point (NSAP) address with an Integrated Local Management Interface (ILMI). Several messages that are similar to the following may be logged in the log file:

 %LANE-3-NOREGILMI: ATM1/1/0.7 LEC cannot register

 39.000000000000000000000022.000163728428.07 with ILMI

 %LANE-3-NOREGILMI: ATM1/1/0.6 LEC cannot register

 39.000000000000000000000022.000163728428.06 with ILMI

This symptom is observed on a Cisco router that has a PA-A3 port adapter and that is running Cisco IOS Release 12.2(10a). This symptom is observed after the software is upgraded from Cisco IOS Release 12.2(8)T4.

Workaround: Reload the router.

CSCdy81424

Symptom: Same issue as DDTS CSCdx58649 except the fix was not committed to the LightStream 1010 image.

Workaround: None.

CSCdy50426

Symptom: After upgrading the switch image, the LightStream 1010 switch might lose PNNI neighbors. When the "Auto-Config" function becomes stuck, it causes PNNI neighbor loss and prevents soft-PVCs from connecting.

Note ILMI and QSAAL do come up.

Workaround: Use the shutdown and no shutdown commands on the interfaces or reboot the switch to recover.

CSCdy45231

Symptom: No syslog message or generic link down/up trap is generated when an IMA interface goes down.

Workaround: None.

CSCdy44850

Symptom: The command network-clock-select priority system disappears from the running configuration after a switch reload.

After entering the command in global configuration mode, the switch parser adds the keyword "clock" at the end of the line and that causes the reload to skip the command when parsing the configuration file.

Workaround: None.

CSCdy38993

Symptom: A Route Processor crash occurs when address registration fails at the switch. Also, an error message is flashed to the console. This problem occurs when traffic is flowing over a Flexwan module and either a hw-module-reset or OIR has occurred.

Workaround: None.

CSCdy32886

Symptom: When using version UNI 4.0, during SVC call setups, a Catalyst 8500 MSR switch in the "Call Received" state does not send a connect-ack upon reception of a connect. This causes the SVC to be released.

Workaround: Use version UNI 3.1

CSCdy25535

Symptom: On a Catalyst 8500 MSR or LightStream 1010 switch with a DS3 interface, the interface goes down after only 7ms of AIS and then comes back up. For example, the following message appears:

 %LINK-5-CHANGED: Interface ATM1/0/0, changed state to going down

Approximately three seconds later, the next message appears:

 %LINK-3-UPDOWN: Interface ATM1/0/0, changed state to up

Note This might happen when experiencing a protection switchover on the transport network.

Workaround: None.

CSCdy10719

Symptom: Hosts connected to the Catalyst 8540 switch through an Eight Port Gigabit Ethernet module, that do not transmit data frequently are intermittently unreachable.

The connectivity to the hosts eventually recovers.

Workaround: None.

CSCdy07314

Symptom: A Catalyst 8500 MSR running Cisco IOS version 12.0(20)W5(24b) might crash with a bus error in the SNMP code.

Workaround: Disabling polling chassis MIBs might prevent the crash.

CSCdx93120

Symptom: On a Cisco 6400 Node Switch Processor (NSP) running Cisco IOS Release 12.2(2)B and its derivatives, using the atm ping command to test a valid and active VP might fail with the following message:

 Jun 20 15:56:17.742: %ATMCORE-3-INTERNAL_ERROR: atmCore_oamRcvPing: No match.

The failure occurs when running the ping towards specific destination ATM switches, and is dependent on the format of the loopback cell received from the destination ATM switches. The occurrence of this problem is difficult to predict and depends on the particular ATM switch implementation of the destination switch.

Workaround: None.

CSCdx91019

Symptom: A Cisco 6400 NSP, running Cisco IOS Release 12.1(5)DB or 12.2(2)B, displays the following error message when you use the atm ping interface atm slot/subslot/port VPI VCI end-loopback command and enter the wrong VP/VC combination:

 connection doesn't exist

Any future atm ping commands to any connections (both valid and invalid) always result in the same error message and the ping commands fail. It fails even if the connection is valid, and even if a VP ping is used (for example, no VC number is specified).

You can still use the IP ping command to diagnose the connectivity between the NRP2 (Node Route Processor 2) and NSP.

Workaround: None.

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.

CSCdx65390

Symptom: When a point-to-multipoint SVC connection is set up through a switch (root and leaf are active and cross-connected), and a request is received to add a leaf through another interface, and the allocation of this half-leg fails, the connection structures associated with this half-leg are not cleaned up. This means when the connection is cleared, that failed connection cannot be released.

This ties up bandwidth and VPI and VCI resources for the root half-leg of the connection.

Note These resources cannot be cleared using the shutdown and no shutdown commands on the interface.

Workaround: None.
