Viewing The Configuration Lock Status; Restoring The Factory Default Settings - Dell S4048T Configuration Manual

• 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: %RPM0-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 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.

Restoring the Factory Default Settings

Restoring the factory-default settings deletes the existing NVRAM settings, startup configuration, and all
configured settings such as, stacking or fanout.
To restore the factory default settings, use the restore factory-defaults stack-unit {stack—unit—
number | all} {clear-all | nvram | bootvar} command in EXEC Privilege mode.
CAUTION: There is no undo for this command.
