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 "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
