Configure VLANs on a FWSM to send netflow information

WE have several 6509/13's as our core switches with FWSM's in them. Most of our VLANs are defined on the FWSMs. I have configured netflow on the MSFC for VLANs not behind the fwsm, but cannot seem to configure it on VLANs defined on the FWSMs. Are there different commands and procedures for configuring netflow on a FWSM?

Selltekk,

I had the same issues within our network. Currently the FWSM does not support Netflow at all. The only method of extraction of Netflow data from your core switch / FWSM is using a collector like NProbe or FProbe. It takes Span traffic (mirror port) and converts to Netflow data that can be pasted to SW. I have it setup and its giving amazing information about our network.

I don't think the FWSM supports NetFlow; AFAIK it's only supported on ASAs.
