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 Interface IP Address S/L Description --------- ---------- --- ----------- eth0 172.16.51.129/24 u/u OUTSIDE eth1 192.168.0.1/24 u/u INSIDE eth1.100 192.168.100.1/24 u/u VLAN 100 lo 127.0.0.1/8 u/u ::1/128
