Introduction to User Interface 33
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.
■
TTY user interface is numbered after Console user interface and before Aux
user interface.
■
Number of AUX user interface is the absolute number of TTY plus one.
■
VTY user interface is numbered after AUX user interface. Absolute number of
the first VTY is incremented by 1 than the AUX user interface number.
2 Relative number
Relative number, represented by “+ number” assigned to each type of user
interface. It follows the rules below:
■
Console user interface is numbered CON 0.
■
Number of TTY user interface: The first TTY user interface is designated as
TTY0, the second one is designated as TTY1 and so on.
■
AUX user interface is numbered AUX 0.
■
Number of VTY user interface: The first VTY user interface is designated as
VTY0, the second one is designated as VTY1 and so on.
