Open Caveats in Software Release4.5(3)
Note For a description of caveats resolved in software release4.5(3), see the “Resolved Caveats in
Software Release4.5(3)” section on page40.
This section describes open caveats in software release4.5(3).
• 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).
(CSCdk55355)
• 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)
• In some cases, after a switchover from the active to the standby supervisor engine, the SPAN
destination port might not function correctly. (CSCdk55360)
• When there are ELANs configured on an ATM module but a corresponding VLAN is not configured
on the supervisor engine, you might see a 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)
• Communication using SLIP on the console port of a Supervisor EngineII might fail.
(CSCdm45445)
• Frame Priority is set incorrectly from Ethernet to FDDI. A new command, set option fddi-user-pri,
has been added to enable the priority field in the FDDI packets. The command requires FDDI
software release 3.2(1a) and supervisor engine software release 5.5(2) or later. This problem is
resolved in software release 5.5(2). (CSCdr42228)
• The Catalyst 5000 family switch is unable to resolve DNS names if the DNS server has more than
7 entries. (CSCdr808353)
