Open and Resolved Caveats in Software Release 4.5(1)
In some cases, enabling IGMP snooping on a switch with a Supervisor EngineIII causes the switch
to reset. The problem occurs when one of these special multicast addresses is used for normal
multicast data traffic:
01-00-5e-00-00-01
01-00-5e-00-00-02
01-00-5e-00-00-04
01-00-5e-00-00-05
01-00-5e-00-00-0d
This problem is resolved in software release4.5(1). (CSCdk76272)
In some cases, in a switch with a Supervisor EngineI or II and an ATM module, the ATM module
might not receive VTP updates from the VTP server after the switch or the module is reset.
Workaround: Session to the ATM module, shut down the ATM interface (using the shutdown
command), wait five seconds, and then bring the interface back up (using the no shutdown
command). This problem is resolved in software release4.5(1). (CSCdk80168)
In some cases, autonegotiation fails when connecting some 10/100-Mbps Fast Ethernet modules to
a Compaq4000 system with the Netflex 3 NIC. This problem is resolved in software release4.5(1).
(CSCdk87853)
In some cases, entering the show cdp neighbors detail command causes the switch to generate
“alignment correction” syslog messages. These messages do not affect the functionality of the
switch. This problem is resolved in software release4.5(1). (CSCdk85671)
After reloading a switch with an RSM and multiple ISL trunk links, the state of configured VLAN
interfaces on the RSM might change to down.
Workaround: Disconnect all of the ISL links and then reconnect them one at a time. This problem
is resolved in software release4.5(1). (CSCdk81521)
On the Token Ring modules (WS-X5030 or WS-X5031), if you move the SPAN destination from
port to port, the ports might stop forwarding traffic. This problem is resolved in software
release4.5(1). (CSCdk88229)
On a switch with Supervisor EngineIII, if the system message logging level is set to 7 for all
facilities, then entering the show logging buffer command can cause an exception error, causing the
switch to reset. This problem is resolved in software release4.5(1). (CSCdk93930)
The RSM autostate function does not shut down TrBRF VLAN interfaces when there are no active
ports in any of the TrBRF’s child TrCRFs. This problem is resolved in software release4.5(1).
(CSCdk75627)
In some cases, when using the IBM type1 cabling system, packet loss might occur on the 48-port,
10BASE-T Ethernet module (WS-X5012) if the port is incorrectly terminated (such that the port is
placed in external loopback mode). This problem is resolved in software release4.5(1).
(CSCdk56632)
Enabling an ISL trunk on a switch with many (spanning tree enabled) VLANs can cause the switch
to delay BPDU transmission on TrBRF and TrCRF VLANs if the switch is the root bridge for any
of the defined VLANs. This problem is resolved in software release4.5(1). (CSCdk69087)
In some cases, enabling SPAN can cause a memory leak, causing the switch to return an “out of
memory” error. This problem is resolved in software release4.5(1). (CSCdk92662)
