[flow-tools] Catalyst 6509's && GSR/Juniper

[Darren Smith]

Hi Ian

I assume you mean switch from CATOS completely.

Mmmm, how stable is IOS for CATOS these days? Is CATOS even supported still?

/me remembers back to the dim and distant past and a very ill native IOS
6509 he saw :-(

Got any urls for the differences i'm likely to see? between the two?

Lasty, would you recommend netflow accounting from the core switches? or
rather from 7xxx/GSR's at the edges?

We could potentially see upto 7-800Mb/sec of traffic into the network from
various edges.

Regards

Darren
