Open and Resolved Caveats in Software Release 7.6(14)
Resolved Caveats in Software Release 7.6(15)
These caveats are resolved in software release 7.6(15):
• A Catalyst 4500 series switch may crash when running 802.1x and multiple ports receive a down
link event followed by a link up. This problem is resolved in software release 7.6(15).
(CSCsb60960)
• Under very rare and undetermined conditions, you might experience a condition in which the CAM
aging time cannot be changed from the default value of 300 seconds. This lock condition is possibly
triggered by a spanning tree topology change at the same time the set cam agingtime vlan value
command is entered. The lock condition might also be the result of migrating from PVST+ to Rapid
PVST+.
Workaround: Reload the switch or revert momentarily to PVST+ and then back to Rapid PVST+.
This problem is resolved in software release 7.6(15). (CSCef29999)

These caveats are resolved in software release 7.6(14):
• Not all MST topology change events (TCs) are counted in the show spantree mod/port mst instance
command output. The TCs are needed to determine the source and track the count of topology changes
to troubleshoot excessive flooding. This problem is resolved in software release 7.6(14). (CSCsb11469)
