Vyatta Network OS Documentation

Learn how to install, configure and operate the Vyatta NOS, which helps drive our virtual networking & physical platforms portfolio.

Viewing system interfaces

You can configure only interfaces that are physically available to the operating system on the hardware you are using. To view all the interfaces known to the operating system, use the show interfaces system command in operational mode, as shown in the following example. In this example, the system has two physical Ethernet interfaces, dp0p1p1 and dp0p1p2, plus a VLAN interface (vif) configured for VLAN 40 that is under dp0p1p2.
