## Configure QinQ

This section contains an example of how to configure QinQ in SEFOS. In this example, two end devices are connected to two QinQ-enabled SEFOS switches, as shown in the following illustration. The end nodes communicate using untagged frames, as well as frames tagged with `VID=50`. The SEFOS switches are interconnected with `VID=25`.

1. Configure switch 1.

       SEFOS# configure terminal
       SEFOS(config)# shutdown spanning-tree
       SEFOS(config)# set gvrp disable
       SEFOS(config)# set gmrp disable
       SEFOS(config)# shutdown garp
       SEFOS(config)# bridge-mode provider
       SEFOS(config)# vlan 25
       SEFOS(config-vlan)# port extreme-ethernet 0/3
       SEFOS(config-vlan)# exit
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# switchport pvid 25
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface extreme-ethernet 0/15
       SEFOS(config-if)# switchport access vlan 25
       SEFOS(config-if)# switchport acceptable-frame-type untaggedAndPrioritytagged
       SEFOS(config-if)# switchport mode access
       SEFOS(config-if)# switchport mode dot1q-tunnel
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# spanning-tree mode mst
       SEFOS(config)# spanning-tree compatibility mst
       SEFOS(config)# exit

2. Review the VLAN output.

       SEFOS# show vlan
       Vlan database

3. Configure switch 2.

       SEFOS# configure terminal
       SEFOS(config)# shut spanning-tree
       SEFOS(config)# set gvrp disable
       SEFOS(config)# set gmrp disable
       SEFOS(config)# shutdown garp
       SEFOS(config)# bridge-mode provider
       SEFOS(config)# vlan 25
       SEFOS(config-vlan)# port extreme-ethernet 0/3
       SEFOS(config-vlan)# exit
       SEFOS(config)# interface extreme-ethernet 0/3
       SEFOS(config-if)# switchport pvid 25
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# interface extreme-ethernet 0/15
       SEFOS(config-if)# switchport access vlan 25
       SEFOS(config-if)# switchport acceptable-frame-type untaggedAndPrioritytagged
       SEFOS(config-if)# switchport mode access
       SEFOS(config-if)# switchport mode dot1q-tunnel
       SEFOS(config-if)# no shutdown
       SEFOS(config-if)# exit
       SEFOS(config)# spanning-tree mode mst
       SEFOS(config)# spanning-tree compatibility mst
       SEFOS(config)# exit
