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: %SYSTEM-P:CP %SYS-5-CONFIG_I: Configured from console by console Dell#config !

If you forget your password, follow these steps: 1. Log onto the system using the console. 2. Power-cycle the chassis by disconnecting and then reconnecting the power cord. 3. During bootup, press Esc when prompted to abort the boot process. You enter Boot-Line Interface (BLI) mode at the BOOT_USER# prompt. 4. At the BLI prompt, set the system parameter to ignore the enable password and reload the system: BOOT_USER# ignore enable-password BOOT_USER# reload NOTE: You must manually enter each CLI command. The system rejects a command if you copy and paste it in the command line. 5. Configure a new password. Switch Management 81
