fastethernet port on a 3Com SS II switch. Port 1 is a FE port that is
configured for monitoring. Port 4 is configured as the analysis port.
I am running ethereal on a laptop connected to the analysis port.
Ethereal is monitoring in promiscuous mode. I see incoming broadcast
traffic on port 1 but I never see the traffic generated on either ports
2 or 3 that should be leaving the switch via port 1 to an upstream
switch. I see STP packets coming down the port 1 pipe, probably from
the upstream switch, as well. Are there any gotchas to getting this to
work?
Some pertinent information from the switch:
