Cadet,

We also have the following device that doesn't appear to support Netflow. Can you advise on the the service module we would need?

That's brilliant mate.

I will take that to my boss in the morning.

Cadet,

If my boss would like to see alternatives to purchasing a service module, can you think of any other ways we could monitor traffic flowing across our 3750 or 4500 without purchasing a Netflow Services Module?

Cheers

Cisco Netflow Configuration on 3750

Hi Cadet,

Thanks again for getting back to me.

I'm looking at the link you provided above. While I was reading I saw the following statement:

The only Cisco switches that support Netflow are the  4500 and 6500 series switches

However, our 4500 L3 switch won't support netflow. Is there any reason why?

We also can't configure span port on the switch :-(

Purple

Cisco Netflow Configuration on 3750

Hi,

it doesn't support flexible Netflow(v9) but surely regular Netflow. Here's a note concerning SPAN on the 4500 switch:http://thwack.solarwinds.com/thread/24243

Alain
