Vyatta NOS documentation

Learn how to install, configure, and operate Vyatta Network Operating System (Vyatta NOS), which helps to drive our virtual networking and physical platforms portfolio.

Candidate and running configurations

Vyatta NOS keeps two versions of the configuration current — candidate and running.

You can also think of these as the 'uncommitted' and 'committed' configuration, respectively.

Running/committed configuration
This is the configuration that is currently in use with the live system.
Candidate/uncommitted configuration
By default, this is simply a copy of the running configuration — until you modify it. You can modify it as much as you like to draft changes that you might commit to the running configuration.
