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.

Recovering from a Forgotten Password

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, 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.
CONFIGURATION mode
enable {secret | password}
6 Save the change in the running configuration to the startup configuration.
