Open Caveats in Software Release 7.5(1)
These caveats are open in software release 7.5(1):
• A Catalyst 4500 series switch running in the access layer may display loop guard-inconsistent
messages if a topology change occurs in corresponding designated switches that have a high number
of spanning tree instances. The switch recovers on its own and does not cause a network outage.
Workaround: There is no workaround. (CSCdz65842)
• When a port receives a VLAN assignment from the RADIUS server and the port mode is set to
multiple-hosts, the output of the show port command may show the old VLAN. The feature works
correctly, allowing multiple hosts.
Workaround: Ignore the output of the show port command. The output of the show spantree
command displays the correct port in the appropriate state. (CSCin26149)
• If you change the port control of an authorized 802.1X port from auto to force-authorized, the port
may display incorrect VLAN information in the output of the show port command and an error
might occur when you try to change the VLAN for the port.
Workaround: Disable and enable the port after changing port-control from auto to
force-authorized. (CSCin25709)
• When CGMP is enabled on a Catalyst 4500 series switch, IGMP global leave is not generated after
a spanning tree topology change occurs in MST mode.
Workaround: Switch to PVST+ or Rapid PVST+ mode. (CSCdz50009)
• The ciscoMemoryPoolUsed and ciscoMemoryPoolFree values may report incorrect values when
compared to the output for the show version command. These values indicate that SNMP reports a
greater use of NVRAM then normal.
Workaround: There is no workaround. (CSCdz42968)
Resolved Caveats in Software Release 7.5(1)
These caveats are resolved in software release 7.5(1):
• When you enable port security on a multi-VLAN access port, voice traffic may be switched
untagged. The switch may learn the MAC address for an IP phone in both the static CAM and
dynamic CAM. There is no workaround.This problem is resolved in software release 7.5(1).
(CSCin19097)
• When switch CPU utilization approaches zero, a Catalyst 4500 series switch may return an invalid,
negative value for the cpmCPUTotal5sec and cpmCPTotal1min values. This problem is resolved in
software release 7.5(1). (CSCdz42365)
