Network Interfaces
|
|
==================
|
|
|
|
Configured interfaces on a VyOS system can be displayed using the
|
|
`show interfaces` command.
|
|
|
|
.. code-block:: sh
|
|
|
|
vyos@vyos:~$ show interfaces
|
|
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
|
|

|
|
A specific interface can be shown using the `show interfaces <type> <name>`
|
|
command.
|
|
|
|
.. code-block:: sh
|
|
|
|
vyos@vyos:~$ show interfaces ethernet eth0
|
|

Different network interfaces provide type-specific configuration. Ethernet
|
|
interfaces, for example, allow the configuration of speed and duplex.
|
|
|
|
Many services, such as network routing, firewall, and traffic policy also
|
|
maintain interface-specific configuration. These will be covered in their
|
|
respective sections.
