3Com SSII roving analysis

I am having difficulty setting up an analysis port to monitor a 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:
