[c-nsp] L2 Link Failover

[Tim Vollebregt]

Hi,

I assume you are using the channel-group mode on mode right now, when the physical is up your switch will balance packets.

You should try using the channel-group mode active (LACP), as there is an handshake in the LACP protocol. When there is no end-to-end connectivity, and the handshake doesn't succeed it will remove the port from the LACP bundle.

Regards,

Tim
