We have a Cisco 6506 and we have IP NetFlow configured on the LAN/WAN interfaces (both are gigbitethernet ports). We have "ip flow ingress" on the LAN interface which is sending the stats back to our server.
However if we configure "ip flow egress" on the WAN port, it stops sending the stats back to our server completely. Is there a hardware issue on the 6506's related to NetFlow? Or a bug? I've done a bug search on the platform and there is nothing obvious related to what we are seeing.
We know it's not our configuration because we have a duplicate configuraion on a Cisco 6524 and that one has no issues and is sending the stats to our server with no issues.
This is the IOS we are using:
The version we're using is:
ip flow-export version 5
