Usage Guidelines

Usage Scenario

If a user logs in to a device through an vty port, the system automatically allocates an idle user interface with the smallest number and a specified type to the user based on the login mode. The user interface helps manage and monitor the session between the device and the user. Each user interface has a corresponding user interface view where you can set a series of parameters, such as whether user authentication is required during the login and the user level after login. These parameters restrict the users that log in through this user interface, achieving unified session management.

Follow-up Procedure

After logging in to the device as a network administrator, run the display user-interface command to view user interfaces currently supported and the absolute and relative numbers of these user interfaces.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# Entering into vty view for updating vty 0 configuration.

<HUAWEI> system-view
[~HUAWEI] user-interface vty 0
[~HUAWEI-ui-vty0] authentication-mode aaa
[~HUAWEI-ui-vty0] user privilege level 3
[~HUAWEI-ui-vty0] idle-timeout 0 0
Warning: Idle time-out is configured as 0, so session will never be disconnected because of timeout.
[~HUAWEI-ui-vty0] screen-length 0
