Netflow & IP Multicast

[KENT EITZMANN]

Hi,

We are using Cisco's Flowcollector software (latest verion) to collect Netflow information from a 7204VXR (12.0.7T) using the DetailASMatrix aggregation. I've noticed that I'm not seeing any flows pertaining to the IP multicast traffic going through this router, everything else works fine.

Any ideas ?

Thanks

I got an answer to my question elsewhere, but thought I would post it here in case someone had the same question.

According to TAC, "At present Netflow doesn't capture the multicast datagram. Development is going on for multicast support and this features should be integrated by beginning of next year."

I'm not sure if this is just an issue with the Flowcollector software or whether it will also require changes with the router IOS.
