Open and Resolved Caveats in Software Release 4.5(4)
Open Caveats in Software Release4.5(4)
Note For a description of caveats resolved in software release4.5(4), see the “Resolved Caveats in
Software Release4.5(4)” section on page38.
This section describes open caveats in software release4.5(4).
• When the backup concentrator relay function (CRF) is configured on the Catalyst 5000 supervisor
engine, it is stored in the NVRAM, but when you enter a copy config command, the CRF
configuration parameters do not get copied with the rest of the switch configuration. If the switch is
power-cycled, the backup CRF configuration is retained in the NVRAM. (CSCdp38648)
• If a switch is configured with the sc0 interface in a Token Ring VLAN and there are parallel trunks
to another switch, it is possible for the first switch to erroneously detect a duplicate IP address. This
can lead to excessive console messages being displayed, making the console unusable.
Workaround: Move the sc0 interface into an Ethernet VLAN. (CSCdm93084)
• 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. (CSCdm92714)
• 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)
• 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)
