or
commit
Example:
RP/0/RSP0/CPU0:router(config-if)# end
or
RP/0/RSP0/CPU0:router(config-if)# commit
Saves configuration changes.
• When you issue the end command, the system
prompts you to commit changes:
Uncommitted changes found, commit them
before exiting (yes/no/cancel)?
[cancel]:
–
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.
