Destination 
MAC Address

Specify an MAC address with which the Switch uses to encapsulate the 
layer 2 protocol packets by replacing the destination MAC address in the 
packets.

Note: The MAC address can be either a unicast MAC address or 

multicast MAC address. If you use a unicast MAC address, 
make sure the MAC address does not exist in the address 
table of a switch on the service provider’s network. 

Note: All the edge switches in the service provider’s network should 

be set to use the same MAC address for encapsulation.

Port

This field displays the port number.
