Administrator Guide

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.
View the Conguration 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.

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
