I have 3750 poe (IOS ver 12.2 (25r)SEE4) switch that is responding very slowly. Utilization is as follows: CPU @ 6%, Memory [email protected]%, Memory 2@ 66%. Apart from the switch complaining of a power supply failure and a Eigrp neighbour not being on a common subnet, I cannot see anything obvious why the switch’s memory is heavily utilised @ 66% and slowing down the response time of the switch. Please advice. Thanks
Check to see if you are running IDS / IPS If you are you will see high memory useage. It is normal when using it... You may need to scale back on some of the signatures...
I saw that you are using aprox. 25M from aprox.90M available. That's not such high utilisation if you have a decent amount of traffic. I have checked some of my 3750 in the production environment and I have about 30M utilisation.
And why you are saying that CEF is not working?
To check if CEF is indeed disabled on a interface do:
show cef interface Fa x/0/y
and check for the filed IP CEF
I think you have nothing to worry about.
Let me know if this helps and please rate if it does!
