I generally just use set span "source vlan" mod/port# and then plug your
sniffer in.
I have several switches with 200 users (10/100rj45) and 300 users (rj21)
and receive no significant hit.
You can use ps -c to check switch performance.
Don't use the set span enable. Everytime I tried this, the switch needs to
be rebooted. I haven't figured out why yet.
