| 5 | device. Once configured, every packets arriving at one of the port with |
| 6 | specific VLAN tag will be sent to another port directly. Current |
| 7 | implementation only matches on the outermost VLAN tag. If the packet is double |
| 8 | tagged, the S-tag will be matched and both the S-tag and C-tag will be |
| 9 | persisted. |
| 10 | |
| 11 | VLAN cross connect only works on the same device. If you are looking for |
| 12 | transporting L2 traffic across devices, please refer to :doc:`pseoduwire |

| 15 | View cross connect via CLI |
| 16 | -------------------------- |
| 17 | To view a list of cross connects configured in the system through ONOS CLI: |
| 18 | |
| 19 | .. code-block:: text |
| 20 | |
| 21 | sr-xconnect |
| 22 | |
| 23 | Add cross connect via CLI |
| 24 | ------------------------- |
| 25 | |
| 26 | .. code-block:: text |
| 27 | |
| 28 | sr-xconnect-add <deviceId> <vlanId> <port1> <port2> |
| 29 | |
| 30 | - ``deviceId``: device ID, e.g. **of:0000000000000201** |
| 31 | - ``vlanId``: VLAN ID, e.g. **94** |
| 32 | - ``port1``: One end of the cross connect, e.g. **2** |
| 33 | - ``port2``: Another end of the cross connect, e.g. **54** |
| 34 | |
| 35 | Remove cross connect via CLI |
| 36 | ---------------------------- |
| 37 | |
| 38 | .. code-block:: text |

| 81 | For a given port, we should avoid using the same VLAN ID in both xconnect and interface configuration at the same time (regardless of untagged, tagged or native) |
