Configuring IEEE 802.1Q Tunneling

Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
◆
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.
◆
The specified ethertype only applies to ports configured in Uplink mode using
the switchport dot1q-tunnel mode
unspecified), the TPID is always 8100. If the port is in Access mode, received
packets are processes as untagged packets.
Example
Console(config)#interface ethernet 1/1
