VTY line view, VTY line class view
Predefined user roles
network-admin
mdc-admin

all: Supports both protocols.

telnet: Supports Telnet only.
Usage guidelines
This configuration is effective only for a user who logs in through the user line after the configuration is completed.
Before configuring a user line to support SSH, set the authentication mode to scheme for the user line. For more information, see authentication-mode.
In VTY line view, this command is associated with the authentication-mode command. If you specify a non-default value for only one of the two commands in VTY line view, the other command uses the default setting, regardless of the setting in VTY line class view.
Examples
# Enable user lines VTY 0 through VTY 4 to support only SSH.
<Sysname> system-view [Sysname] line vty 0 4 [Sysname-line-vty0-4] authentication-mode scheme [Sysname-line-vty0-4] protocol inbound ssh
# Enable scheme authentication for the VTY line class and enable the line class to support only SSH. Disable authentication for VTY lines 0 through 4.
<Sysname> system-view [Sysname] line class vty [Sysname-line-class-vty] authentication-mode scheme [Sysname-line-class-vty] protocol inbound ssh [Sysname-line-class-vty] line vty 0 4 [Sysname-line-vty0-4] authentication-mode none
