Resolved Caveats in Software Release4.5(5)

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

Release4.5(6)” section on page31.

This section describes caveats resolved in software release 4.5(5):

• 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)

• 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)

• When a VTP client and a VTP server in a VTP domain are separated from each other by a VTP

transparent mode switch that is not a member of any VTP domain and the client is reset, the client

does not update its configuration after receiving a VTP update from the VTP server. This problem

is fixed in software release 4.5(5). (CSCdp05027)

• Telnet sessions to the switch are not released properly. This problem is fixed in software release

4.5(5). (CSCdp15609)

• If a switch is configured with the sc0 interface in a Token Ring VLAN and there are parallel trunks

to another switch, the first switch might 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. This problem is fixed in software

release 4.5(5). (CSCdm93084)

• Use of the set standbyports enable command to enable a port on a backup Supervisor Engine III

associates an ifIndex number with the port, which can be displayed by the show port command, but

the MIB object cdpInterfaceEntry does not see this ifIndex number. This causes CiscoWorks2000

map discovery to fail. To avoid this problem, reset the standby supervisor engine. This problem is

fixed in software release 4.5(5). (CSCdm30287)

• Communication using SLIP on the console port of a Supervisor EngineII might fail. This problem

is fixed in software release 4.5(5). (CSCdm45445)

• Multicast and broadcast traffic is not cleared correctly from the counters when the clear counter

command is issued. This problem is fixed in software release 4.5(5). (CSCdm94354)

• VTP Clients do not learn new configurations from each other.When the update timer in one VTP

client times out, it has to send a request advertisement but this request does not reach other clients

and the requesting client remains stuck waiting for the rest of the configuration. Resetting the switch

or changing the state of the switch enables the hung client to learn the configuration. This problem

is fixed in software release 4.5(5). (CSCdm90300)

• Cut-and-paste does not work with the session command for the WS-X5167 OC-3 ATM module.

This problem is fixed in software release 4.5(5). (CSCdp18016)
