User Guidelines
This command configures the TPID value on the outer VLAN (S-VLAN).
The global configuration form of the command configures all physical and
port-channel interfaces to use the specified ethertype. The interface form of
the command enables/disables the use of the ethertype on the specific
interface. The ethertype used in the interface form of the command must use
the same ethertype as specified in the global configuration form of the
command. The inner vlan tag (C-TAG) is configured using the switchport
command in interface configuration mode.
