One user interface corresponds to one user interface view where you can configure a set of parameters,
such as whether to authenticate users at login, whether to redirect the requests to another device, and the
user privilege level after login. When the user logs in through a user interface, the parameters set for the
user interface apply.
At present, the system supports the following CLI configuration methods:
• Local configuration via the console port
• Local/Remote configuration through Telnet
The methods correspond to the following user interfaces.
• Console user interface: Used to manage and monitor users that log in via the console port. The type
of the console port is EIA/TIA-232 DCE.
• VTY (virtual type terminal) user interface: Used to manage and monitor users that log in via VTY. A
VTY port is a logical terminal line used for Telnet access.
Users and user interfaces
Only one user can use a user interface at a time. The configuration made in a user interface view applies
to any login user. For example, if user A uses the console port to log in, the configuration in the console
port user interface view applies to user A; if user A logs in through VTY 1, the configuration in VTY 1 user
interface view applies to user A.
Numbering user interfaces
User interfaces can be numbered by using absolute numbering or relative numbering.
Absolute numbering
Absolute numbering identifies a user interface or a group of different types of user interfaces. The
specified user interfaces are numbered from number 0 with a step of 1 and in the sequence of console
and then VTY user interfaces. You can use the display user-interface command without any parameters
to view supported user interfaces and their absolute numbers.
Relative numbering
Relative numbering allows you to specify a user interface or a group of user interfaces of a specific type.
The number format is “user interface type + number”. The following rules of relative numbering apply:
• The console port is numbered 0: CON 0.
• VTYs are numbered from 0 in the ascending order, with a step of 1.
