2911 router - Netflow V5 through GRE Tunnels

Hi All,

Does the 2911 router support the ability for Netflow V5 to pass through GRE tunnels? I can't seem to find any documentation that indicates this.

Thanks,

Gurjinder

If you are going to use a GRE tunnel as the flow export interface from the router exporting NetFlow, it will not work. Cisco bug IDs for this issue are CSCsk25481 and CSCef28662 and is applicable to both traditional and flexible NetFlow.

To allow NetFlow export from a device through an encrypted tunnel on the same device, enable Flexible NetFlow and use the command output-features when configuring your flow exporter. That will allow NetFlow export over encrypted tunnels.
