Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.3.xSG
OL-26675-02
Troubleshooting
–
The RADIUS server becomes available again, and a dot1x client attempts to authenticate.
Workaround: None. CSCtx61557
• Front panel power supply LEDs do not always correspond to power supply state.
Workaround: None. CSCtz01430
• After booting a switch with Cisco IOS XE 3.3.0SG or 3.3.1SG with a crypto (k9) image, a linecard
may display a status of Auth Fail, and will not be brought online. Non-crypto images are unaffected.
Workaround: Reset the linecard either with the hw-module module m reset command or through
a manual OIR. CSCuc64146
• With IGMP snooping enabled, multicast traffic received through a tunnel interface is not forwarded
out the Outgoing Interface List.
Workaround: Disable IGMP snooping. CSCuc65538
• When a port connected to a CDP speaker goes down, a small memory leak occurs (typically less than
300 bytes).
Workaround: Disable CDP on interfaces that may flap frequently. CSCub85948
• A GLC-GE-100FX pluggable may not operate when used in WS-X4624-SFP-E,
WS-X4640-CSFP-E or WS-X4612-SFP-E modules.
Workaround: None CSCui23911
Resolved Caveats for Cisco IOS XE Release 3.3.0SG
This section lists the resolved caveats for Cisco IOS XE Release 3.3.0SG:
• If you enter the show spanning-tree vlan command when spanning tree is changed from PVST to
Rapid PVST, the ports configured as promiscuous trunks are not listed as part of the spanning tree.
Workaround: Enter shut and no shut on the ports. CSCtn88228
• If you enter the show mem detailed process ? command on a Supervisor Engine 7-E switch, a list
of processes is not displayed.
Workaround: Enter the complete command string, for example:
show mem detailed process cli_agent
CSCtj05663
• If you enter the clear ip mroute ? command, only the vrf option is displayed. The Hostname and '
* ' options are not displayed, even though they are accepted by the system. The clear ip mroute
command functions as expected.
Workaround: None. CSCto59368
