44 CHAPTER 4: USER INTERFACE CONFIGURATION
■ AUX port: A view which you log in from the AUX port. AUX port is also a line
device port. The device has only one AUX port of EIA/TIA-232 DTE type. This
port is usually used for dialup access via modem.
■ VTY (Virtual Type Terminal): A view which you log in through VTY. VTY port is a
logical terminal line used when you access the device by means of Telnet or
SSH. Currently, each device supports up to five VTY users to access
simultaneously.
User Interface
Numbering
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 (representing the
Console port), and followed by 1 (representing the AUX port), then 2 to represent
VTY 0, and so on.
n
The numbering approach numbers the three types of user interfaces in the
sequence of: Console port, AUX port and VTY. The Console interface and the AUX
interface each occupy a number, and the four VTY user interfaces are numbered
from 0 to 4.
You can use the display user-interface command to view the number of the user
interfaces.
Relative numbering
Relative numbering numbers a user interface in the form of "user interface type +
number". In this way, it can specify a user interface or a group of user interfaces of
a specific type. This form of number is valid only when used under that type of
user interface. It makes no sense when used under other types of user interfaces.
The rules of relative numbering are as follows:
■ CON is numbered CON 0.
■ AUX is numbered AUX 0.
■ VTYs are numbered from 0 in ascending order, with a step of 1.
