Configuring Q-in-Q Tunnels and Layer 2 Protocol Tunneling Chapter 9 Configuring Q-in-Q VLAN Tunnels Send document comments to [email protected] Step 3 Command switchport Purpose Sets the interface as a Layer 2 switching port. Step 4 Example: switch(config-if)# switchport switchport mode dot1q-tunnel Creates a 802.1Q tunnel on the port. Step 5 Example: switch(config-if)# switchport mode dot1q-tunnel l2protocol tunnel [cdp | stp | vtp] Step 6 Example: switch(config-if)# l2protocol tunnel stp no l2protocol tunnel [cdp | stp | vtp] Enables Layer 2 protocol tunneling. Optionally, you can enable CDP, STP, or VTP tunneling. (Optional) Disables protocol tunneling. Step 7 Example: switch(config-if)# no l2protocol tunnel exit Exits configuration mode. Step 8 Example: switch(config-if)# exit switch(config)# exit copy running-config startup-config (Optional) Copies the running configuration to the Example: startup configuration. 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.
