Managing Configuration Sessions
During regular configuration sessions, the running configuration is locked whenever a commit operation

command:

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

locked and unlocked configuration sessions, see the
“Displaying the Active Configuration Sessions”
section on page 69.
To start an exclusive configuration session for the administration configuration, connect to the and enter
the configure exclusive command in administration EXEC mode:
RP/0//CPU0:router# admin
RP/0//CPU0:router(admin)# configure exclusive
RP/0//CPU0:router(admin-config)#
The running configuration is unlocked when the user who started the exclusive configuration session
exits the configuration mode, as described in the “Ending a Configuration Session” section on page 84.
