Hi all,

I’m looking to get some 7210 controllers and then use tunnelled mode from ports on my 3810 switches.

I understand by default these create GRE tunnels back to the controller. My question is, how can I secure these GRE tunnels? Can I add MACSEC to them or something similar?

The traffic I tunnel from these ports; I want to encrypt to protect the traffic from other users on the switch.

Thanks
