Parameters
key-string: Specifies a shortcut key. It can be a character (case sensitive), or an ASCII code value in
the range of 0 to 127. For example, if you configure lock-key 1, the shortcut key is Ctrl+A. If you
configure lock-key a, the shortcut key is a. For information about ASCII code values of individual
characters, see the standard ASCII code chart. For information about ASCII code values of
combined keys that use the Ctrl key, see Table 6.
Usage guidelines
As a best practice, specify a combined key as the user line locking key. If you specify a single
character as the key, the character acts only as the user line locking key. You cannot type the
character for any commands, keywords, or arguments.
Pressing the user line locking key is equivalent to executing the lock reauthentication command.
This command takes effect immediately.
To display the current user line locking key, use the display current-configuration | include
lock-key command.
Examples
# Set the user line locking key to Ctrl+A for VTY line 0.
<Sysname> system-view
[Sysname] line vty 0
[Sysname-line-vty0] lock-key 1
[Sysname-line-vty0] quit
To verify the configuration:
1. Press Ctrl+A.
[Sysname]
Please press Enter to unlock the screen.
2. Press Enter and enter the login password.
Password:
