Agent interface down

[Visconti]

In my Extreme Managment center I see an alarm :

Agent interface down on interface 20 port 1.20....

but I don t know why this alarm it's present

Those ports are on 2 different switches, they can't both be your PC.

It is monitoring all the ports on you switches, I think its traps that trigger that alarm but I don't remember for sure.

Ok but I have not turned off my pc and so do not understand how it can happen

Someone turned off their computer or unplugged a patch cable.

I would disable the alarm personally. We have used that alarm on a port group containing only uplink ports in the past. Other than that I don't see a use for it.
