[SybilBartelmaos24984]

Hi All, 

is Netflow top talkers supported on Catalyst 8300 routers? and does it require any specific DNA subscription? 

Thanks,

Hello @SybilBartelmaos24984,

Yes, NetFlow is supported for IPv4 and IPv6 in both egress and ingress directions. CEF is required to be enabled to run the Flexible NetFlow "FnF" on the Cisco Catalyst 8300 Series Edge Platforms.

Foor Full Flexible NetFlow (meaning collection of flow data for every packet), you need DNA Essentials or higher.

Hello
I would say if you on the CAT8Ks then you would be using Flexible Netflow? - if so then he command to show top talkers would be-

sh monitor <monitor name> cache sort highest ipv4  <source |destination |protocol>  address top <value> format table
