Does anyone know if this is possible with a 3COM SuperStack
Switch?...the particular models I have are 3000 series.  It appears to
me that you can only mirror the traffic of one specified physical port
to another specified physical port.  I'm pretty sure that setting up
trunks or VLANs would not change this single port limitation.

If you want to mirror ALL traffic, you can set SPAN on the switch. You
enable SPAN (switched port analyzer) by doing the following when in conf
mode:

port monitor [interface]

and of course to disable, 

no port monitor [interface]

Kevin,
   It looks as if you're working with 29XX or 35XX gear using IOS?   Is
this correct?
I think the commands you are looking for is "port monitor fast 0/x". You
should do this inside the fast ethernet interface you want to use as the
monitoring interface and list all the vlans and fast ethernet interfaces
you want to monitor on this interface.  (similar to how you have listed
things in your question)

Hope this helps,

On a Cisco switched network does anybody know how to set one port on one
of the switches to mirror all traffic? I just setup an IDS and this is
the one stumbling block I've hit. I know it's FastEth x/x
        portforward fastEth 0/1
        portforward fastEth 0/2
        and so on..


Does this sound right?
Thanks,
Kevin
