Hi,

Just been thinking to myself about improving our traffic monitoring and wondered if it was possible to monitor traffic flows on a 3560 switch at either L3 or L2?

I immediately thought about netflow or nbar but these aren't supported, are there any other options?

That's a resounding no idea then... hmmm needs more thought.

 

Only monitoring your'll be able to do is SNMP ... not as granular as netflow/nbar, but you dont have them options

 

Have a go with this, I have used in the past, is quite good and free

Cheers, I've got SNMP software but a freebie is always worth a check .

Any idea what the bottom end switch that supports netflow is? I read somewhere that 3750's do but I can't find anything to back that up on the feature navigator and don't have one to check manually myself.
