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.
If any user is already in CONFIGURATION mode when while a lock is in place, the following appears on their terminal
(message 2): % 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.
Recovering from a Forgotten Password on the S6000
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.
EXEC Privilege mode
copy running-config startup-config

3. During bootup, press Esc when prompted to abort the boot process.
You enter Boot-Line Interface (BLI) mode at the BOOT_USER# prompt.
NOTE: You must enter the CLI commands. The system rejects them if they are copied and pasted.
