Open and Resolved Caveats in Software Release 4.5(4)
Resolved Caveats in Software Release4.5(4)
Note For a description of open caveats in software release4.5(4), see the “Open Caveats in Software
Release4.5(4)” section on page37.
This section describes caveats resolved in software release 4.5(4):
• Under certain conditions, the switch can access an out-of-range memory location, causing the switch
to reset. This problem is fixed in software release 4.5(4). (CSCdm81976)
• When there are ELANs configured on an ATM module but a corresponding VLAN is not configured
on the supervisor engine, you might see syslog message such as the following:
1999 Aug 24 17:15:51 EDT -04:00 %PRUNING-4-NOBUF:no mbuf to build join
These messages indicate that a protocol failed to find a memory buffer to perform an operation.
Workaround: Configure the corresponding VLANs on the supervisor engine. The syslog messages
should stop within a few minutes. This problem is fixed in software release4.5(4). (CSCdm30975)
• When using TACACS+, if you open a Telnet session to the switch and enter a username and close
the Telnet session without entering a password, the TACACS+ session from the switch to the
TACACS+ server remains open. This problem is fixed in software release 4.5(4). (CSCdp02341)
• Occasionally, you may see “%SPANTREE-3-PORTADD_DISABLE” messages. This message
indicates that a port for a given VLAN has been added to the spanning tree in a disabled state.
Examine the condition of the port. Contact your technical support representative.These messages
have been moved to severity level 7 in software release 4.5(4). (CSCdp06238)
• The switch might not respond to SNMP requests for a while if an SNMP set command is issued on
MIB object vlanPortIslVlansAllowed when the port is an RSM module. This problem is fixed in
software release 4.5(4). (CSCdp03818)
• Periodically, the switch reboots with an “MCP not responding” message. This problem is fixed in
software release 4.5(4). (CSCdm90981)
• With MLS configured to use more than one MLS-RP and with the MLS-RPs configured for HSRP,
when a Spanning Tree Protocol topology change occurs, MLS cache entries are deleted and
occasionally may not be re-created. This problem is fixed in software release 4.5(4). (CSCdm90511)
• In a redundant Token Ring topology with ISL trunking, it is possible for a ping from a Catalyst 5000
series switch to a Catalyst 3900 switch to fail. Other network traffic is not affected. This problem is
fixed in software release 4.5(4). (CSCdp07427)
• When you configure a permanent multicast CAM entry for multiple ports and you change the port
VLAN membership for multiple ports, the supervisor engine receives an exception and reloads.
Only the first port listed retains the new VLAN membership, and is removed from the permanent
cam entry. This problem is fixed in software release 4.5(4). (CSCdm91321)
• If you configure a Supervisor EngineI as a VTP client, the switch might reset when the trunk link
to the VTP server is enabled. This problem is fixed in software release4.5(4). (CSCdm92411)
• When linked to ports on switches that do not limit channels to contiguous ports, such as ports on
Catalyst 6000 family switches and ports on the WS-X5410 Gigabit EtherChannel switching module,
ports at either end of the channel might be incorrectly bundled, which may cause a network loop
resulting in disabled ports. This is fixed in software release 4.5(4). (CSCdm49693)
