[c-nsp] Risk of enabling ip accounting

[Mike Louis]

The parser accepts it and i can setup top talkers on it. It used to be supported on the old 3550s as well. More than likely all in software.

One of SupV or SupV-10GE support an integrated Netflow card i thought it was the later. I will look it up and get back with the group. Thanks for the input.

Mike

Unfortunately this isn't true at all. 4948s are SupV based, which by
itself needs NetFlow daughter card to be able to count and export
NetFlow packets. The daughter card doesn't fit into 1U so no, 4948
can't export NetFlow. It's possible however that there's in CLI and
parser accepts it - as usual IOS parser may not actualy reflect
what's supported and what's not. In this case you'd propably get
NetFlow exports only for traffic hitting RP (not processed in hardware).

By the way, it's listed officially as unsupported feature in latest
release notes here:
