If any user is already in CONFIGURATION mode when while a lock is in place, Message 2 appears on
their terminal.
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 command
show configuration lock 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 command
clear from EXEC Privilege mode. If you clear a console session,
the user is returned to EXEC mode.
Recovering from a Forgotten Password on the S55
If you configure 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.
If you forget your password:
Message 2 Cannot Lock CONFIGURATION mode Error
% 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.
