• 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.
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
***********************************************************************
* Warning - Restoring factory defaults will delete the existing *
* persistent settings (stacking, fanout, etc.) *
* After restoration the unit(s) will be powercycled immediately. *
* Proceed with caution ! *
