 Anyone know about the:
  Cisco Catalyst 3750 ?
  Nortel Passport 8600/1600 ?

 As for the 3550-EMI "real life" experience as a 10/100 BT aggregation switch 
wasn't affected(CPU <5%) at all by rather aggressive scanning but did
generate around 11 Mb/sec of ARP requests on all the 100Mb/sec ports in the same
VLAN and totally killed connectivity to legacy equipment connected at 10 Mb/s ...
