DESCRIPTION
Select this to enable layer 2 protocol tunneling on the Switch.
Specify a 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.
This field displays the port number.
Use this row to make the setting the same for all ports. Use this row first and then make
adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Select this option to have the Switch tunnel CDP (Cisco Discovery Protocol) packets so that
other Cisco devices can be discovered through the service provider's network.
Select this option to have the Switch tunnel STP (Spanning Tree Protocol) packets so that
STP can run properly across the service provider's network and spanning trees can be set
up based on bridge information from all (local and remote) networks.
