Users And User Interfaces; User Interface Number; Common User Interface Configuration - H3C WA Series Fundamentals Configuration Manual

One user interface corresponds to one user interface view, where you can configure a set of parameters,
such as authentication mode at login and the user levels after login. When a user logs in through a user
interface, the user's access is restricted by these parameter settings. Thus, the centralized
management of user sessions can be achieved.

Users and User Interfaces

User interfaces (also called lines) allow you to manage and monitor users that log in through different
methods. An AP provides one console user interface and five VTY user interfaces.
User interfaces do not associate with specific users. When a user initiates a connection request, based
on the login type the system automatically assigns an idle user interface with the smallest number to the
user. During the login, the configuration in the user interface view takes effect. The user interface varies
depending on the login type and the login time. For example, User A can use VTY 0 to log in to an AP,
and User B can also use VTY 0 to log in to the AP when User A logs out.

User Interface Number

User interfaces can be numbered in two ways: absolute numbering and relative numbering.
1) Absolute numbering:
The console user interface is numbered first, with the absolute number 0.
VTY user interfaces are numbered after the console user interface. The VTY user interfaces are
numbered from 1, with a step of 1.
2) Relative numbering numbers a user interface in the form of "user interface type + number". The
rules of relative numbering are as follows:
The console user interface is numbered Console 0.
VTY user interfaces are numbered from 0, with a step of 1, such as VTY0, VTY1.

Common User Interface Configuration

Follow these steps to perform common user interface configuration:
To do...
Lock the current user interface
Send messages to all user
interfaces or a specified user
interface
Disconnect a specified user
interface
Display the information about the
current user interface/all user
interfaces
Display the physical attributes and
configuration of the current/a
specified user interface
Enter system view
Use the command...
lock
send { all | num1 | { console | vty }
num2 }
free user-interface { num1 |
{ console | vty } num2 }
display users [ all ]
display user-interface [ type
number | number ] [ summary ]
