Service Manual

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.
Important Points to Remember
• When you restore all the units in a stack, these units are placed in standalone mode.
• When you restore a single unit in a stack, only that unit is placed in standalone mode. No other units
in the stack are affected.
