Configuring VLAN Mapping

This example shows how to bundle all traffic on the port to leave the router with the S-VLAN ID of 100.

Router(config)# interface gigabiethernet0/1

Router(config-if)# switchport mode dot1q-tunnel

Router(config-if)# switchport access vlan 100

Router(config-if)# exit

Configuring Selective QinQ on a Tunnel Port

Beginning in privileged EXEC mode, follow these steps to configure VLAN mapping for selective QinQ

on a trunk port. Note that you can configure one-to-one mapping and selective QinQ on the same

interface, but you cannot use the same C-VLAN IDs in both configurations.

Use the no switchport vlan mapping vlan-id outer vlan-id command to remove the VLAN mapping

configuration. Entering no switchport vlan mapping all deletes all mapping configurations.

This example shows how to configure selective QinQ mapping on the port so that traffic with a C-VLAN

ID of 1 to 5 enters the router with an S-VLAN ID of 100. The traffic of any other VLAN IDs is tagged

as VLAN 123.

Router(config)# interface gigabiethernet0/1

Router(config-if)# switchport mode dot1q-tunnel

Router(config-if)# switchport access vlan 123

Router(config-if)# switchport vlan mapping 1 100

Router(config-if)# switchport vlan mapping 2 100

Router(config-if)# switchport vlan mapping 3 100

Router(config-if)# switchport vlan mapping 4 100

Router(config-if)# switchport vlan mapping 5 100

Step 6

number

Verify the configuration.

Step 7

Command Purpose

Step 1

configure terminal Enter global configuration mode.

Step 2

interface interface-id Enter interface configuration mode for the interface connected to the

service-provider network.

Step 3

switchport mode dot1q-tunnel Configure the interface as a 802.1Q port.

Step 4

switchport vlan mapping

original-vlan-id translated-vlan-id

Enter the VLAN IDs to be mapped:

• vlan-id—the customer VLAN ID (C-VLAN) entering the router from

the customer network. The range is from 1 to 4094. You can enter a

string of VLAN-IDs.

• outer-vlan-id—Enter the outer VLAN ID (S-VLAN) of the

service-provider network. The range is from 1 to 4094.

Step 5

end Return to privileged EXEC mode.
