Administrator Guide

If another user attempts to enter CONFIGURATION mode while a lock is in place, the following appears

on their terminal (message 1): % Error: User "" on line console0 is in exclusive

configuration mode.

If any user is already in CONFIGURATION mode when while a lock is in place, the following appears on

their terminal (message 2): % Error: Can't lock configuration mode exclusively since

the following users are currently configuring the system: User "admin" on line

vty1 ( 10.1.1.1 ).

NOTE: The CONFIGURATION mode lock corresponds to a VTY session, not a user. Therefore, if you

configure a lock and then exit CONFIGURATION mode, and another user enters CONFIGURATION

mode, when you attempt to re-enter CONFIGURATION mode, you are denied access even though

you are the one that configured the lock.

NOTE: If your session times out and you return to EXEC mode, the CONFIGURATION mode lock is

unconfigured.
