Hi

What about some other things to consider?
- Placing some policing config on the inbound traffic (only 3550 supports 
that)

- using rmon commands to generate traps/syslog on ports that change their 
pattern too fast

Most of our servers are connected to one of two switches, is there anyway I can look at switchport utilization or some other method on the switch to help narrow down or identify which box is being hacked?
