Usage Guidelines

Usage Scenario

Before committing a set of configuration, run the display configuration candidate changes command to view the difference between the candidate configuration and current running configuration.

The display configuration candidate merge command displays the difference between the configuration in the candidate configuration database and that in the running configuration database. If a configuration difference exists, the command output is displayed as follows:

Commands that exist in the candidate configuration rather than the current running configuration are prefixed with "+".
Commands that exist in the current running configuration rather than the candidate configuration are prefixed with "-".
If a command in the current running configuration is modified in the candidate configuration, two commands that are prefixed with "-" and "+", respectively, are displayed in sequence.

To check whether the configuration to be committed is correct and whether it conflicts with the existing configurations, you can run the display configuration candidate merge command.

Precautions

This command applies only to the two-phase validation mode.

Before you run the commit command to commit a configuration, a configuration conflict occurs if the current running configuration is changed. In this case, run the refresh configuration candidate command to resolve the configuration conflict, and then run the display configuration candidate changes command to view the configuration difference.

The actual command output varies according to the device. The command output here is only an example.
