Cisco devices that support NetFlow for flow-based traffic analysis

What about ASR series routers?

ANDY,

Do you know for sure if Orion's NTA works with Cisco's "FLEXIBLE NETFLOW"?

We've been trying to get Netflow working with Orion NTA from a Cisco 6513 and I was just told by someone (a CCIE) this is the key to making Layer 2 ports on Cisco 6513 work with Netflow. Of course we've seen it work with VLANs off this switch which are Layer 3.

Thanks.

Hi lchance,

Not OOB. Chris La Point is more up to date on the product features at this point. I'll forward the thread on to him for his input.

lchance, have you tried the "ip flow ingress layer2-switched vlan x" command? Works fine for me on the 6513 with NTA.

The big problem with NetFlow on the Catalyst 6500 series in general is that depending on which PFC/DFC you have, the NetFlow TCAM is limited to 128k or 256k entries, which means that if you have a high-volume box with a lot of unique flows, you're going to miss flows just due to hardware limitations.

I don't run into this problem because I don't have that many unique flows.

thanks - we're trying it today.
