Re: OT: Monitoring 3550 routed traffic w SNMP

You could run cacti to graph all the interfaces and apply an aggregate
graph to view all the traffic. This assumes there are trunk interfaces
you want to accurately monitor.

Spanning is an interesting idea, but you're only going to get transmit
bits/s from your SNMP output.
