User interfaces The device uses user interfaces (also called "lines") to control CLI logins and monitor CLI sessions. You can configure access control settings, including authentication, user privilege, and login redirect on user interfaces. After users are logged in, their actions must be compliant with the settings on the user interfaces assigned to them. Users are assigned different user interfaces, depending on their login methods, as shown in Table 10. Table 10 CLI login method and user interface matrix User interface AUX user interface Virtual type terminal (VTY) user interface Login method Console port (EIA/TIA-232 DCE), locally or remotely by using modems Telnet or SSH User interface assignment The device automatically assigns user interfaces to CLI login users, depending on their login methods. Each user interface can be assigned to only one user at a time. If no user interface is available, a CLI login attempt will be rejected. The device provides 1 AUX user interfaces and 8 VTY user interfaces. For a CLI login, the device always picks the lowest numbered user interface from the idle user interfaces available for the type of login. For example, four VTY user interfaces (0 to 3) are configured, of which VTY 0 and VTY 3 are idle. When a user Telnets to the device, the device assigns VTY 0 to the user and uses the settings on VTY 0 to authenticate and manage the user. User interface identification A user interface can be identified by an absolute number, or the interface type and a relative number. An absolute number uniquely identifies a user interface among all user interfaces. The user interfaces are numbered starting from 0 and incrementing by 1 and in the sequence of AUX and VTY user interfaces. You can use the display user-interface command without any parameters to view supported user interfaces and their absolute numbers. A relative number uniquely identifies a user interface among all user interfaces that are the same type. The number format is user interface type + number. Except for TTY user interfaces, which are numbered starting from 1 and incrementing by 1, all the other types of user interfaces are numbered starting from 0 and incrementing by 1. For example, the first AUX user interface is AUX 0. A relative number uniquely identifies a user interface among all user interfaces that are the same type. The number format is user interface type + number. The user interfaces are numbered starting from 0 and incrementing by 1. For example, the first AUX user interface is AUX 0, and the second AUX user interface is AUX 1. 22

User interfaces
The device uses user interfaces (also called "lines") to control CLI logins and monitor CLI sessions. You
can configure access control settings, including authentication, user privilege, and login redirect on user
interfaces. After users are logged in, their actions must be compliant with the settings on the user
interfaces assigned to them.
Users are assigned different user interfaces, depending on their login methods, as shown in Table 10.

User interface assignment
The device automatically assigns user interfaces to CLI login users, depending on their login methods.
Each user interface can be assigned to only one user at a time. If no user interface is available, a CLI
login attempt will be rejected.
The device provides 1 AUX user interfaces and 8 VTY user interfaces. For a CLI login, the device always
picks the lowest numbered user interface from the idle user interfaces available for the type of login.
For example, four VTY user interfaces (0 to 3) are configured, of which VTY 0 and VTY 3 are idle. When
a user Telnets to the device, the device assigns VTY 0 to the user and uses the settings on VTY 0 to
authenticate and manage the user.
User interface identification
A user interface can be identified by an absolute number, or the interface type and a relative number.
An absolute number uniquely identifies a user interface among all user interfaces. The user interfaces are
numbered starting from 0 and incrementing by 1 and in the sequence of AUX and VTY user interfaces.
You can use the
display user-interface
command without any parameters to view supported user
interfaces and their absolute numbers.
A relative number uniquely identifies a user interface among all user interfaces that are the same type.
The number format is
user interface type
+
number
. Except for TTY user interfaces, which are numbered
starting from 1 and incrementing by 1, all the other types of user interfaces are numbered starting from
0 and incrementing by 1. For example, the first AUX user interface is AUX 0.
A relative number uniquely identifies a user interface among all user interfaces that are the same type.
The number format is

. The user interfaces are numbered starting from 0 and
incrementing by 1. For example, the first AUX user interface is AUX 0, and the second AUX user interface
is AUX 1.
