I am just wondering if there is a rule of thumb as to how many mirror ports you should put on a 3560G. Our email administrators have asked me to mirror 5 or 6 ports going to different servers and while we should have the processing power and bandwidth, I don't want to cause and degregation in the network. I know the option is there to mirror all traffic from a VLAN to a paticular port. We aren't going to be doing any of that, the mirror is always going to be from one physical machine on a port to a capture pc on another port.
So, what stats on the switch should I be looking at to gauge if these mirror ports are taxing the system? We currently have 3 ports running now and have no issues.

decision. To do this we require the switch to do...
