configuring netflow for layer 2 switched traffic on my cat6509

Hi all

I want to configure layer 2 switched netflow on my cat 6509 running vss,

I have configured the 2 commands below 

ip flow ingress layer2-switched vlan 1,2,3

ip flow export layer2-switched vlan 1,2,3

However, if I look in the config the export bit isnt there after?

It is running a PFC


Should layer 2 switched netflow work in this chassis ?

it says on the Cisco site that it works on the below

"The command is supported on Supervisor Engine 720 in PFC3B and PFC3BXL mode only and on Supervisor Engine 2 with a PFC2"

so is it not possible for me ?

Hello Carl,

it should be supported you have a PFC3C > PFC3B


Except in PFC3A mode, NetFlow supports bridged IP traffic. PFC3A mode does not support NetFlow bridged IP traffic.



only the first command is reported in cfg guide


the NDE export part should be configured as usual as you do for the routed traffic.

Hope to help
