telnet [ip-address]
If you do not enter an IP address, the system enters a Telnet dialog that prompts you for one.
Enter an IPv4 address in dotted decimal format (A.B.C.D).

Lock CONFIGURATION Mode
The systems allows multiple users to make congurations 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 locks: 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 congure 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 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.
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.
