Users 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

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 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.

Recovering from a Forgotten Password

If you congure authentication for the console and you exit out of EXEC mode or your console session times out, you are prompted for a

password to re-enter.

Use the following commands if you forget your password.
