Chapter 4 User Interface Configuration
4.1 User Interface Overview
User interface configuration is another way provided by the switch to configure and
manage the port data.
The Switch 8800 supports the following configuration methods:
z
Local configuration via the Console port and AUX port
z
Local and remote configuration through Telnet on Ethernet port
z
Remote configuration through dialing with modem via the AUX port.
According to the above-mentioned configuration methods, there are three types of user
interfaces:
z
Console user interface
Console user interface is used to log in the switch via the Console port. A switch can
only have one Console user interface.
z
AUX user interface
AUX user interface is used to log in the switch locally or remotely with a modem via the
AUX port. A switch can only have one AUX user interface. The local configuration for it
is similar to that for the Console user interface.
z
VTY user interface
VTY user interface is used to telnet the switch. A switch can have up to five VTY user
interface.
User interface is numbered in the following two ways: absolute number and relative
number.
I. Absolute number
The user interfaces for IP PBX fall into three types and they are sequenced as follows:
console interface (CON), auxiliary interface (AUX) and virtual interface (VTY). A switch
has one CON, one AUX and multiple VTYs. The first absolute number is designated as
0; the second one is designated as 1; and so on. This method can specify a unique user
interface or a group of interfaces.
It follows the rules below.
z
Console user interface is numbered as the first interface designated as user
interface 0.
z
AUX user interface is numbered as the second interface designated as user
interface 1.
