Concept Guide

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

DellEMC(conf)#configuration mode exclusive auto

BATMAN(conf)#exit

3d23h35m: %RPM0-P:CP %SYS-5-CONFIG_I: Configured from console by console

DellEMC#config

! Locks configuration mode exclusively.

DellEMC(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 congure 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 congured the lock.

NOTE: If your session times out and you return to EXEC mode, the CONFIGURATION mode lock is uncongured.

Restoring the Factory Default Settings

Restoring the factory-default settings deletes the existing NVRAM settings, startup conguration, and all congured 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 aected.

• 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.

DellEMC#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 ! *

Proceed with factory settings? Confirm [yes/no]:yes
