i've installed a NFC in the following scenario: Cat4500 SUPIV, IOS 12.2(25)EWA1.
Netflow commands configured:
ip route-cache flow infer-fields
ip flow ingress infer-fields
ip flow ingress layer2-switched
ip flow-cache timeout inactive 30
ip flow-cache timeout active 2
ip flow-export source Vlan147
ip flow-export version 5
ip flow-export destination <ip> 9996
I've several SVI's connected, all configured in a uniform manner. But the WAN SVI-Interface, which is a DTM ethernet connection, only shows incoming traffic. The peer interface which is homed on a 6509 show in- and outgoing traffic. Netflow collector is Netflow Analyzer 7. I'm stumped, why is only one SVI showing this issue?
I suspect the 4506 only has that one WAN-SVI interface with "ip route-cache flow" configured, so it's entirely expected behavior you only see incoming traffic, because NetFlow is unidirectional only and ingress by default (and as configured).
On the other hand, the 6509 does not exhibit the problem, probably because it has multiple interfaces with "ip route-cache flow" on. So you're getting the bi-directional picture of the traffic flowing through two of the 6509's interfaces (in through one, out through another), because the Netflow Analyzer software can stitch two interfaces' ingress records into one duplex conversaion.
It is not possible to configure "ip route-cache flow" on the svi's of the 4506. it has ios 12.2(25)EWA1 installed and the command is not available. I guess i'll do an update the next days first, and try to configure the command again after the new version is running.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
