3.2.2 User Interface Numbering for the Router

User interface of the system falls into four categories, and is arranged in certain order:
They are Console (CON), Auxiliary port (AUX), virtual interface (VTY) and physical
terminal interface (TTY).There is only one user interface for console and auxiliary port,
while multiple user interfaces for VTY and TTY interface, each type of these multiple
user interfaces being arranged in order.
User interface is numbered in the following two ways: absolute number and relative
number.
1) Absolute number
The beginning number of absolute number is 0 (Namely, Console port), and the rest
interfaces can be deduced by analogy. Console port and Aux port occupy one number
respectively; For VTY interface and TTY interface, different products support different
numbers of user interfaces. Use the display user-interface command to view them.
Absolute number can uniquely specify one user interface or one group of user
interfaces.
Console user interface is numbered 0.
