Hi thanks for the reply, Kirk.
Currently doing Netflow Analysis on my 7k's where the gateways live. We have host's on our 5k's in the same subnet, they never touch the 7k's if they are passing traffic between each other on the same VLAN.
The L3 switch is a 3750. My idea is to use solarwinds to monitor netflow on the 3750 interface that plugs into the 5k span port. I figured, the 5k would span all traffic to this port, the 3750 would send the flow records to solarwinds which would analyze.
Trying to avoid purchasing a separate piece of hardware just to see traffic on the Nexus 5596up.
