commands to get detailed information on a per-port basis for your SPA. The use of these commands is
indicated at the end of each configuration task.

commit
Example:
RP/0/0/CPU0:router(config-if)# end
or
RP/0/0/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.
