thanks for your help

Your configuration looks okay. I would look at the following
is the response time the same from another host on the switch you are on or from a different switch; is the response time the same morning, noon, and evening
from you network monitoring tool is the trunk interface at a high utilization, there were a few drops on the G0/1 interface
try minimizing broadcast traffic (G0/1 showed 953272629 broadcasts) - sh arp | in Incomplete will show you nonexistent destinations sources are trying to reach regularly

i try to do ping for another pc and the behavior is the same, all day
this behavior is only in my switch´s 2950, because i have in the same network a 2960 behind the 2950 and the ping of the 2960 y ok (2ms)
another idea?
thanks

I'm at a loss. My last thoughts are either cpu utilization or bug in IOS. If you could revert to your last IOS and maybe troubleshoot.

I don't downgrade the IOS, beacuse I lost the conexion via ssh, and this is the requeriment for my information security department
I do think the change my all switch 2950 to 2960, what do you think?
thanks
