Configured interfaces on a VyOS system can be displayed using the show interfaces command.
A specific interface can be shown using the show interfaces <type> <name> command.

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.
