I have 4 Catalyst 2960S, and they have the same problem.
The CPU usage is 60% before I telnet them.
It fell to 20% when I using telnet to login. And raised to above 60% after logout.
This is the output of 'show proc cpu' when I login.
This is the output of 'show proc cpu' 2 mins later.
And the traffic chart will like this.
How can I to solve this problem?
The hardware & software version is:
WS-C2960S-48TS-L 12.2(53)SE1 C2960S-UNIVERSALK9-M
Many thanks for any comments.
Also my first post:-)
We have the same problem on our stacks.
1 52 WS-C2960S-48FPD-L 12.2(55)SE2 C2960S-UNIVERSALK9-M
2 52 WS-C2960S-48FPD-L 12.2(55)SE2 C2960S-UNIVERSALK9-M
3 52 WS-C2960S-48FPD-L 12.2(55)SE2 C2960S-UNIVERSALK9-M
4 52 WS-C2960S-48FPD-L 12.2(55)SE2 C2960S-UNIVERSALK9-M
CSCth24278 is still not solved in 12.2(58)SE or SE1 (according to the release notes)
I could not download the release notes of SE2 (it presents SE instead)
I'll upgrade 2 of our 9 stacks this weekend to the new c2960s-universalk9-mz.150-1.SE.bin (posted on july 26, 2011)
No words of CSCth24278 in this document!
lets see and wait!
