Open and Resolved Caveats in Software Release 4.5(7)

• If you save a configuration file from a switch where Token Ring is not configured, and then apply

the saved configuration file to that same switch, it is safe to ignore messages about TRBRF and

TrCRF VLANs. These messages are caused by the default Token Ring VLAN configuration, which

is always present regardless of the specific configuration of the switch. This problem is resolved in

software release 4.5(7). (CSCdm92714)

• The SNMP getone and getnext commands produce different values for the same dot1dTpFdbPort

object when they retrieve LANE module port index information from the CAM table. This problem

is resolved in software release 4.5(7). (CSCdp80044)

• The WS-X5225R module fails to negotiate the duplex mode correctly after a system reset or power

cycle with Sun workstations “Ultra 5." This problem is resolved in software release 4.5(7).

(CSCdr03818)

• After a system reset under traffic, the switch initializes to VLAN 0 and Spanning Tree Protocol sets

the ports to Forwarding state. Due to a short delay before the correct VLAN is set, packets might

come in with VLAN 0 learned, which causes VLAN 0 CAM entries to be created and isolates the

ports from connected devices. This problem is resolved in software release 4.5(7). (CSCdr21314)

• In certain situations, incoming traffic is missing on the SPAN port when spanning from

WS-X5012A module to WS-X5011 module or from WS-X5011 to WS-X5224 module using a

different bus. This problem is resolved in software release 4.5(7). (CSCdr22775)

• The show TopN utility reports errors on trunk ports when no errors occurred. This problem is

resolved in software release 4.5(7). (CSCdr23551)

• After closing a Telnet session, the switch still shows the session as open. Using the disconnect

ip_address command to disconnect a user and manually close the session does not close the session.

This problem is fixed in software release 4.5(7). (CSCdp33649)

• A memory corruption might occur if you insert a standby supervisor engine or boot up a redundant

system that has fewer VLANs configured than the active supervisor engine. This problem is

resolved in software release 4.5(7). (CSCdp98884)

• The show top command incorrectly reports errors on trunk. This problem is resolved in software

release 4.5(7). (CSCdr23551)

• On Catalyst 5000 platforms, if the protocol filtering feature is enabled when the switch is reset,

IGMP Snooping will not be able to process IGMP reports or other IGMP messages.

Workaround: Ensure that protocol filtering is disabled when a switch is reset. Once the switch is

reset with protocol filtering disabled, IGMP will work correctly. If you desire both features, the

following workaround can be applied:

a. Enable IGMP Snooping.

b. Disable protocol filtering.

c. Reset the switch.

d. Enable protocol filtering.

Note Note, in the above scenario, IGMP Snooping will again not work if the switch is reset a

second time (since now both features are enabled).

This problem is resolved in software releases 4.5(7). (CSCdr61567)
