Release Notes for Catalyst 4500 Series Software Release 7.x
OL-1983-28
Open and Resolved Caveats in Software Release 7.6(9)
• A Catalyst 2980G switch might not prune VLANs as expected in a trunk when bouncing the trunk.
Workaround: Disable VTP Prunning. This problem is resolved in software release 7.6(10).
(CSCef20698)
• When you use the scheduled reset feature, the associated process (scheduleReset) might report
several dynamic memory allocations in the show memuse command output, while the show proc
mem command would not report any memory allocated or freed. This problem is resolved in
software release 7.6(10). (CSCef50204)
• Your switch might crash if two SSH clients try to connect to the switch at the same time.This
problem is resolved in software release 7.6(10). (CSCef60473)
• A switch can crash with the following error:
Exception 2: Tlb exception (load or fetch)" at epc =>gcc2_compiled.(+ 0) after decoded
the crashdump.
This problem is resolved in software release 7.6(10). (CSCef65161)
• The switch does not respond properly when the logout timer is set to 3 (set logout 3) if you are
accessing the switch through a Telnet session and the screen is either holding the display at the
“More” prompt, the “Enter Password” prompt, or the “Username” prompt. The logout timer is
ignored during these conditions, allowing the connection to remain open beyond the configured
logout timer setting. This problem is resolved in software release 7.6(10). (CSCef15158)
• The dot1dStpPortDesignatedPort MIB might return the wrong value as compared to the show
spantree statistics mod/port command output. This problem is resolved in software release 7.6(10).
(CSCef79667)
• The switch displays the following syslog message when the system is under a Denial of Service
attack:
TCP-2-TCP_MAXESTABLISHED:Possible TCP ACK attack. . Maximum established connection
limit 64 reached. Will drop unused connection
However, under some circumstances, the syslog might be generated when the system is not under
attack. The system functionality is not affected. This problem is resolved in software release 7.6(10).
(CSCef77162)
• When standard MST is used with Layer 2 protocol tunneling, there might be convergence issues at
the remote customer end. This problem is resolved in software release 7.6(10). (CSCef73654)
