This example shows how to create an 802.1Q tunnel port:
switch# configure terminal
switch(config)# interface ethernet 7/1
switch(config-if)# switchport
switch(config-if)# switchport mode dot1q-tunnel
switch(config-if)# exit
switch(config)# exit
switch# show dot1q-tunnel

Changing the EtherType for Q-in-Q

You can change the 802.1Q EtherType value to be used for Q-in-Q encapsulation.

Configuring Q-in-Q Tunnels and Layer 2 Protocol Tunneling
Purpose
Enters global configuration mode.
Specifies an interface to configure, and enters
interface configuration mode.
Sets the interface as a Layer 2 switching port.
Creates a 802.1Q tunnel on the port. The port will go
down and reinitialize (port flap) when the interface
mode is changed. BPDU filtering is enabled and
CDP is disabled on tunnel interfaces.
(Optional) Disables the 802.1Q tunnel on the port.
Exits configuration mode.
(Optional) Displays all ports that are in dot1q-tunnel
mode. Optionally you can specify an interface or
range of interfaces to display.
(Optional) Copies the running configuration to the
startup configuration.
