Users 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.
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.
• When you restore the units in standalone mode, the units remain in standalone mode after the
restoration.
• After the restore is complete, the units power cycle immediately.
The following example illustrates the restore factory-defaults command to restore the factory default
settings.
Dell#restore factory-defaults stack-unit 1 nvram
