Hello,
This is reagrding one of our switch in production - Cisco 3560G. IOS image running is c3560-ipbase-mz.122-25.SEE2/c3560-ipbase-mz.122-25.SEE2.bin
Below is detailed issues & observations:
1) Telnet/Console Access is extremely Slow.
2) Although no teams whose devices are connected to this switch have not raised any concern. But we get ping drops when we try to ping any IP address
of connected servers or other switches from this affected switch.
3) No issue with CPU usage, it is well below 20%. No issue of choked bandwidth on any of the switch interfaces.
4) Tried to check for any Memory leaks but nothing relelvant found.
5) Switch is working as L3 with several SVI created for different server networks.
6) Switch uptime is almost 6 years - not too sure if this may have any relevance with the issue we are facing.
Please provide your valuable suggestion on how should we troubleshoot this further to identify the exact root cause of this issue.
Let me know if any other details are required.
Regards.

switch uptime is about 6 years
Most of the time, this could be a potential culprit.

Post the output to the command "sh proc cpu | ex 0.00".

Hmmmm ... nothing wrong, as far as I can see from our output.
Have you considered upgrading the firmware of your switch to, say, 12.2(55)SE7?

Hello Leo,
We have several other similar switches running the same IOS without any issues. Also, this switch was also running well since past several years as well, so this does not looks to be related to IOS image.
The only thing which we can think of at this point is that the switch uptime is about 6 years so reboot might be required. But that does not have any logical interpretation.
Any other ideas are welcomed.
Thanks.
