I have 3750 poe (IOS ver  12.2 (25r)SEE4) switch that is responding very slowly. Utilization is as follows: CPU @ 6%, Memory 1@29%, 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

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!
