Lock CONFIGURATION Mode
The system allows multiple users to make configurations at the same time. You can lock
CONFIGURATION mode so that only one user can be in CONFIGURATION mode at any time (Message
2).
You can set two types of locks: auto and manual.
• Set auto-lock using the configuration mode exclusive auto command from
CONFIGURATION mode. When you set auto-lock, every time a user is in CONFIGURATION mode, all
other users are denied access. This means that you can exit to EXEC Privilege mode, and re-enter
CONFIGURATION mode without having to set the lock again.
• Set manual lock using the configure terminal lock command from CONFIGURATION mode.
When you configure a manual lock, which is the default, you must enter this command each time you
want to enter CONFIGURATION mode and deny access to others.

Viewing the Configuration Lock Status

If you attempt to enter CONFIGURATION mode when another user has locked it, you may view which
user has control of CONFIGURATION mode using the show configuration lock command from
EXEC Privilege mode.
You can then send any user a message using the send command from EXEC Privilege mode.
Alternatively, you can clear any line using the clear command from EXEC Privilege mode. If you clear a
console session, the user is returned to EXEC mode.
Example of Locking CONFIGURATION Mode for Single-User Access
Dell(conf)#configuration mode exclusive auto
BATMAN(conf)#exit
3d23h35m: %SYSTEM-P:CP %SYS-5-CONFIG_I: Configured from console by console
Dell#config
! Locks configuration mode exclusively.
Dell(conf)#
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
