Netflow Accounting using SPAN?

Hello,

I have a need to perform some traffic accounting on a layer 2 only network. I have an NMS that is capable of receiving Netflow exports.

Does anyone know if it is possible to hang a router off one switch and SPAN a port(s) to it so that it may export the flows to the NMS? I wouldn't want the router to do anything with the packets other than record the flows and export the data.

Thanks,

Dave

Thank you,

Not quite what I was after but still a useful document. I have resigned to the fact that I will need an RMON probe to get this layer 2 accounting working.

Thanks again.
