or

RP/0/RP0/CPU0:router(config)# commit

Saves configuration changes.

• When you issue the end command, the system prompts you to commit changes:

– Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode.

– Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes.

– Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes.

• Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.

Step 1
