Lock CONFIGURATION Mode
Dell Networking OS allows multiple users to make configurations at the same time. You can lock CONFIGURATION mode so that
only one user can be in CONFIGURATION mode at any time (Message 2).
You can set two types of lockst: auto and manual.
● Set auto-lock using the configuration mode exclusive auto command from CONFIGURATION mode. When you
set auto-lock, every time a user is in CONFIGURATION mode, all other users are denied access. This means that you can exit
to EXEC Privilege mode, and re-enter CONFIGURATION mode without having to set the lock again.
● 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.
Recovering from a Forgotten Password on the Z9000
System

prompted for a password to re-enter.
If you forget your password, use the following commands.
1. Log onto the system using the console.
2. Power-cycle the chassis by disconnecting and.then reconnecting the power cord.
3. Press Esc when prompted to abort the boot process.
