you will need to use Q-in-Q tunnels as EAPS requires at least two  
vlans (one for the tagged control vlan, one or more for data).

Also, I would recommend you set the failtimer expiry-action on the  
EAPS master node to open the secondary port when the failtimer  
expires. If you leave the failtime expiry-action to its default value,  
EAPS will not detect if a connection goes down while the ports on the  
switches stay up. When the action is set to open-secondary-port, the  
master node will open its secondary port as soon as it stops receiving  
control packets on its secondary port.
