Users and User Interfaces
A device can support two AUX ports and multiple Ethernet interfaces, and thus multiple user interfaces
are supported. These user interfaces do not associate with specific users.
z
When the user initiates a connection request, based on the login type the system automatically
assigns a type of idle user interface with the smallest number to the user.
z
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.
At a time, only one user can use the user interface. The user interface configuration applies to the user
that has logged in. For example, if user A uses the console port to log in, the configuration in user
interface view of the console port applies to user A; if user A logs in through VTY 1, the configuration in
user interface view of VTY 1 applies.
User Interface Number
User interfaces can be numbered in two ways: absolute numbering and relative numbering.
Absolute numbering
Absolute numbering allows you to uniquely specify a user interface or a group of user interfaces. The
numbering system starts from number 0 with a step of 1. The numbering approach numbers the two
types of user interfaces in the sequence of AUX port and VTY.
Relative numbering
Relative numbering can specify a user interface or a group of user interfaces of a specific type. The
number is valid only when used under that type of user interface. It makes no sense when used under
other types of user interfaces.
Relative numbering numbers a user interface in the form of “user interface type + number”. The rules of
relative numbering are as follows:
z
AUX user interface number is 0 and 1.
z
VTYs are numbered from 0 in ascending order, with a step of 1.
