| VLAN Sub-Interfaces (802.1Q)
 | |
| ----------------------------
 | |
| .. _interfaces-vlan:
 | |
| 
 | |
| 802.1Q VLAN interfaces are represented as virtual sub-interfaces in VyOS. The
 | |
| term used for this is `vif`. Configuration of a tagged sub-interface is
 | |
| accomplished using the configuration command
 | |
| `set interfaces ethernet <name> vif <vlan-id>`.
 | |
| 
 | |
| .. code-block:: sh
 | |
| 
 | |
|   set interfaces ethernet eth1 vif 100 description 'VLAN 100'
 | |
|   set interfaces ethernet eth1 vif 100 address '192.168.100.1/24'
 | |
|   set interfaces ethernet eth1 vif 100 address '2001:db8:100::1/64'
 | |
| 
 | |
| Resulting in:
 | |
| 
 | |
| .. code-block:: sh
 | |
| 
 | |
|   ethernet eth1 {
 | |
|       address 192.168.100.1/24
 | |
|       address 2001:db8:100::1/64
 | |
|       description INSIDE
 | |
|       duplex auto
 | |
|       hw-id 00:0c:29:44:3b:19
 | |
|       smp_affinity auto
 | |
|       speed auto
 | |
|       vif 100 {
 | |
|           address 192.168.100.1/24
 | |
|           description "VLAN 100"
 | |
|       }
 | |
|   }
 | |
| 
 | |
| VLAN interfaces are shown as `<name>.<vlan-id>`, e.g. `eth1.100`:
 | |
| 
 | |
| .. code-block:: sh
 | |
| 
 | |
|   vyos@vyos:~$ show interfaces
 | |
|   Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down

|   eth1.100         192.168.100.1/24                  u/u  VLAN 100
