Open and Resolved Caveats in Software Release 4.5(1)

• If you configure the IP address of the in-band (sc0) interface with an address in subnet zero of a

ClassB address and 24bits of subnet mask, IP traffic destined for other subnets in the same ClassB

network are not forwarded to the default gateway. For example, if the sc0 IP address is

172.20.0.10/24, a ping to any other address in the 172.20 ClassB network (except for those in the

172.20.0 subnet) fails. However, a ping to an address in any other ClassB network succeeds. This

problem is resolved in software release 4.5(2). (CSCdm33248)

Open Caveats in Software Release4.5(1)

Note For a description of caveats resolved in software release4.5(1), see the “Resolved Caveats in

Software Release4.5(1)” section on page46.

This section describes open caveats in software release4.5(1).

• 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).

• On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved

to another, previously unused secured port on the same module, the host cannot connect to the

network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then

reenable port security on the first port (if desired). (CSCdk31747)

• On the Gigabit EtherChannel module (WS-X5410), when the native VLAN of a trunk port is cleared

and then the trunk port is set to off, the port is placed in the inactive state but the Link LED for the

port still shows green. The correct behavior is that the LED for the port should show orange.

(CSCdk31985)

• In some cases, after a switchover from the active to the standby supervisor engine, the SPAN

destination port might not function correctly. (CSCdk55360)

• 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). (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. (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. (CSCdk78241)
