Open and Resolved Caveats in Software Release 4.5(2)

Resolved Caveats in Software Release4.5(2)

Note For a description of open caveats in software release4.5(2), see the “Open Caveats in Software

Release4.5(2)” section on page42.

This section describes caveats resolved in software release 4.5(2):

• In some cases, multiple Catalyst5000 family switches connected through ISL trunk ports might all

report that they are the designated root for the default TrBRF (VLAN1005). This problem is

resolved in software release4.5(2). (CSCdk63476)

• In a system with redundant Supervisor Engine III modules, after a switchover from the active to the

standby supervisor engine, any 48-port, 10BASE-T Ethernet modules (WS-X5012) installed in the

system might reset. The expected behavior is that the modules stay online. This problem is resolved

in software release4.5(2). (CSCdm06609)

• In some cases, when using SPAN on the Token Ring modules (WS-X5030 or WS-X5031), receive

(Rx) traffic is not mirrored to the SPAN destination port. This problem is resolved in software

release4.5(2). (CSCdk78241)

• If DNS is enabled and none of the configured DNS servers is reachable, local password

authentication can be excessively slow. This problem is resolved in software release4.5(2).

(CSCdm14239)

• If you reset the switch with certain Lancast MII transceivers attached, the port to which the

transceiver is attached is marked faulty.

Workaround: Disconnect the transceiver, reset the switch, and then reattach the transceiver after

the switch boots up. This problem is resolved in software release4.5(2). (CSCdk70113)

• Under specific conditions, a spanning tree loop might occur in a redundant configuration with

Catalyst 5000 family and Catalyst 3900 series switches connected using ISL trunks. This problem

is resolved in software release4.5(2). (CSCdm24178)

• In some cases, if you enable PortFast on a port on the Gigabit Ethernet uplink module (WS-U5534)

and the attached end station is rebooted, the port stops transmitting traffic. The port continues to

receive traffic.

Workaround: Disable and then reenable the port (using the set port disable and set port enable

commands) after the end station has rebooted, or disable PortFast on the port (using the set spantree

portfast disable command). This problem is resolved in software release4.5(2). (CSCdm27416)

• In some cases, when the active link of an UplinkFast link pair is disconnected, the switch does not

transmit broadcast frames on the secondary link. This problem is resolved in software release4.5(2).

(CSCdm23587)

• If the Network Analysis Module (WS-X5380) is configured as the SPAN destination port, assigning

a port to a VLAN using the set vlan command might cause an exception error that resets the switch.

This problem is resolved in software release4.5(2). (CSCdm30829)

• In some cases, a Catalyst 5000 family switch might bridge an 802.1Q-encapsulated BPDU if

spanning tree is disabled and both an 802.1Q trunk and an ATM LANE or ISL trunk are configured

on the switch. This problem is resolved in software release4.5(2). (CSCdm26165)
