Rspan causes native vlan issues with CDP

wolf388
Level 1
Level 1

So I have a monitor session that is source vlans 50-150 153-199 destination interface g0/1

Then I have a gigamon connected to that interface. On the other side of the gigamon I am sending traffic out and connecting back to Port g0/13 with another monitor session

Source interface g0/13 destination remote vlan 151.

The trunk going in and out allows all vlans.

When I no shut the port connected to the gigamon out traffic the switch CDPs every port with Native vlan errors. But when I take source all of the above vlans to remote vlan everything works fine, but that bypasses my gigamon.
