Before configuring a user interface to support SSH, set the authentication mode to scheme for the user
interface; otherwise, the protocol inbound ssh command fails. For more information, see
authentication-mode.
By default, the authentication mode of the Telnet protocol is password.
Examples
# Enable the VTYs 0 through 4 to support SSH only.
<Sysname> system-view
[Sysname] user-interface vty 0 4
[Sysname-ui-vty0-4] authentication-mode scheme
[Sysname-ui-vty0-4] protocol inbound ssh

Default level
2: System level
Parameters
screen-length: Number of lines on the next screen, which ranges from 0 to 512. The value of 0 disables
pausing between screens of output.
Description
Use screen-length to set the number of lines on the next screen.
Use undo screen-length to restore the default.
By default, the next screen displays 24 lines.
When screen output pauses, press the Space key to display the next screen. Not all terminals support this
command setting. For example, assume that you set screen-length to 40, but the terminal can display 24
lines in one screen at most. When you press Space, the device sends 40 lines to the terminal, but the next
screen displays only lines 18 through 40. To view the first 17 lines, you must press the page up or page
down key.
To disable multiple-screen output of the current user interface, use the screen-length disable command.
Examples
# Set the next screen of the user interface of console port 0 to display 30 lines.
<Sysname> system-view
[Sysname] user-interface console 0
[Sysname-ui-console0] screen-length 30
