Sorry if this is a stupid question. I�m using a Dell PowerConnect 2708 and mirroring the uplink port (port 1) to port 8. I then use a laptop on port 8 to monitor traffic on the switch with Ethereal. However, when I do this I can no longer reach the default gateway (access Internet) from the laptop (monitoring port). If I try before I even start Ethereal, I still can�t, so it must be the port mirroring. Does anyone know why this would be? Can you not send and receive your own packets when you�re monitoring another port? Does this happen on other switches, or is it switch-specific? Thanks in advance.
I don't know a lot about this, but see: http://wiki.ethereal.com/SwitchReference/Dell 

You may also add additional infos there, if you find out more ...
