To facilitate system management, the switches support user interface based 
configuration for the configuration and management of port attributes. Presently, 
the Switch 8800 Family series switches support the following user interface based 
configuration methods:

■

Local configuration via the Console port and AUX port

■

Local and remote configuration through Telnet on Ethernet port

■

Remote configuration through dialing with modem via the AUX port.

According to the above-mentioned configuration methods, there are three types 
of user interfaces:

■

Console user interface

Console user interface is used to log in to the switch via the Console port. A 
switch can only have one Console user interface.

■

AUX user interface

AUX user interface is used to log in to 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.

■

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.

The user interfaces of the Switch 8800 Family routing switch include three types, 
which 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.

■

Console user interface is numbered as the first interface designated as user 
interface 0.
