Shell - H3C S6812 Series Command Reference Manual

This command is available in both user line view and user line class view. A non-default setting in
either view takes precedence over a default setting in the other view. A non-default setting in user
line view takes precedence over a non-default setting in user line class view.
A password change does not take effect for the current session. It takes effect for subsequent login
sessions.

# Set the password to hello for local password authentication on VTY line 0.
<Sysname> system-view

Usage guidelines
The undo shell command is not supported in AUX line view or AUX line class view.
You cannot disable the terminal service on the user line you are using.
When the device acts as a Telnet or SSH server, you cannot configure the undo shell command.
If the undo shell command is configured in user line class view, you cannot configure the shell
command in the view of a user line in the class.
When terminal service is enabled, a user line can be used for device login. If the device is acting as
the redirect server, the user line can also be used for the redirect service. However, the user line can
be used for only one purpose at a time.
Examples
# Disable the terminal service for VTY lines VTY 0 through 4 so no user can log in to the device
through the user lines.
<Sysname> system-view
[Sysname] line vty 0 4
[Sysname-line-vty0-4] undo shell
