Open and Resolved Caveats in Software Release 4.5(11)

The reset is caused by a high number of MLS-enabled interfaces with HSRP and static MAC

addresses configured. The fix allows MLS to be enabled on a large number of interfaces configured

for MLS.

This problem is resolved in software release 4.5(12). (CSCdp08252)

Note that the RSM IOS software must be upgraded to 12.2(1) or later.

• When the ifOperStatus value for the port changes (the port is enabled and disabled, or the link is

brought up and down), the ifLastChange value for the port does not change.

This problem is resolved in software release 4.5(12). (CSCdt69418)

• The switch might reset with a TLB exception when CmpOctetStringWithLen() receives a null

pointer.

This problem is resolved in software release 4.5(12). (CSCdt75849)

Open Caveats in Software Release4.5(11)

Software Release4.5(11)” section on page23.

This section describes open caveats in software release4.5(11).

• On Catalyst 5500 series switches, Gigabit Ethernet autonegotiation is broken on the Gigabit

Ethernet uplink module (WS-U5534) in supervisor engine software releases 4.5(11), 4.5(12), and

4.5(13). Autonegotiation fails only if the other end of the link is also connected to a WS-U5534

uplink module. There is no problem if the other end of the link is connected to another Gigabit

Ethernet module such as the 3- or 9-port modules.

Turning off autonegotiation to avoid the problem is not recommended as this can lead to

spanning-tree loops if you have a unidirectional link. The only workaround is to connect a WS-U5534

uplink module to a different module (not the WS-U5534 uplink module). (CSCdw21589)

• If you have multiple ATM fabric integration modules (WS-X5165) installed and you have more than

50 LECs configured on each module, a multiple-module software download to the modules can take

an excessively long time to complete. For this reason, we recommend that you download software

images one module at a time (by specifying the module number in the download command).
