We are having some intermittent network weirdness where both LAN and WAN get very slow. On different occasions the cause has seemed to be different, so we are to the point of needing to do some more thorough monitoring to determine what's happening after the fact.
We have a couple of switches, a 48-port and a 24-port, both managed (3com/Procurve). I've never done this before, so I don't know if I'm going to kill the switch, but I was thinking of enabling port mirroring on all ports to capture all network traffic. Is this a bad idea?
