3com 5500-EI User Manual

This section describes how to set up command line interface 
management using a local console port connection or over the network.

The switch provides a user interface so that you can configure and 
manage the port data. There are two types of user interfaces, AUX and 
VTY:

■

Use the AUX user interface to log into your switch through the 
console port. A fabric can have up to eight AUX user interfaces.

■

Use the VTY user interface to Telnet to the switch. The switch can 
have up to five VTY user interfaces.

To manage a switch using the command line interface through the local 
console port connection, ensure that you have connected your 
workstation to the console port as described in “Connecting to the 
Console Port” on page 61. 

You can now continue to manage and configure your switch using the 
CLI through its console port.

To manage a switch using the command line interface over a network 
using Telnet:

1 Ensure that you have already set up the switch with IP information as 

described in “Methods of Managing a Switch” on page 56.

2 Check that the IP protocol is correctly installed on your management 

workstation. You can check this by trying to browse the World Wide 
Web. If you can browse, the IP is installed correctly.

3 Check that you can communicate with the switch by entering a ping 

command at the DOS prompt in the following format: 

(where xxx.xxx.xxx.xxx is the switch’s IP address)

If you get an error message, check that your IP information has been 
entered correctly and that the switch is powered up.

4 To open a Telnet session, from the DOS prompt, enter the IP address of 

the switch that you wish to manage in the following format:
