Numbering User Interfaces
User interfaces can be numbered in two ways: absolute numbering and 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 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.
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 rules of relative numbering are as
follows:
z AUX ports are numbered from 0 in the ascending order, with a step of 1.
z VTYs are numbered from 0 in the ascending order, with a step of 1.
