Every time I run Ethereal I only see my own traffic being captured.

I am trying to sniff a Cisco Switch port and I’m SPANing the destination port properly.

I have tested the SPAN switch configuration with one of my peers and he can see the traffic with Ethereal just fine (he has the same hardware I do).

I tried different versions of Ethereal and WinPcap but the problem still persists.

I wonder if there's any way to see if WinPcap is ordering my Ethernet port to be on a promiscuous mode properly and if it does, how can I see if this is actually happening. I see some people using some DOS commands and seeing certain messages that I may not see with the regular user interface.

 

Any help will be appreciated.
