Step 6
no l2protocol tunnel [cdp | stp | vtp]
Example:
switch(config-if)# no l2protocol tunnel
Step 7
exit

Example:
switch# copy running-config startup-config
This example shows how to enable protocol tunneling on 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)# l2protocol tunnel stp
switch(config-if)# exit
switch(config)# exit

Configuring Global CoS for L2 Protocol Tunnel Ports

You can specify a Class of Service (CoS) value globally so that ingress BPDUs on the tunnel ports are
encapsulated with the specified class.

Chapter 9 Configuring Q-in-Q VLAN Tunnels
Purpose
Sets the interface as a Layer 2 switching port.
Creates a 802.1Q tunnel on the port.
Enables Layer 2 protocol tunneling. Optionally, you
can enable CDP, STP, or VTP tunneling.
(Optional) Disables protocol tunneling.
Exits configuration mode.
(Optional) Copies the running configuration to the
startup configuration.
