◆ Use the switchport dot1q-tunnel tpid command to set a custom
802.1Q ethertype value on the selected interface. This feature allows
the switch to interoperate with third-party switches that do not use the
standard 0x8100 ethertype to identify 802.1Q-tagged frames. For
example, 0x1234 is set as the custom 802.1Q ethertype on a trunk
port, incoming frames containing that ethertype are assigned to the
VLAN contained in the tag following the ethertype field, as they would
be with a standard 802.1Q trunk. Frames arriving on the port
containing any other ethertype are looked upon as untagged frames,
and assigned to the native VLAN of that port.
◆ All ports on the switch will be set to the same ethertype.
