3Com Switch 8800 Configuration Guide 

Chapter 2  Logging into Switch

 

2-3 

After you have correctly configured IP address of a VLAN interface for a switch via 

Console port (using ip address command in VLAN interface view), and added the port 

(that connects to a terminal) to this VLAN (using port command in VLAN view), you can 

telnet this switch and configure it. 

Step 1: Before logging into the switch through telnet, you need to configure the Telnet 

user name and password  on the switch through the console port. 

 

  Note: 

By default, the password is required for authenticating the Telnet user to log in the 

switch. If a user logs in via the Telnet without password, he will see the prompt “Login 

password has not been set !”.

(xxxx is the preset login 

password of Telnet user) 

Step 2: To set up the configuration environment, connect the Ethernet port of the PC to 

that of the switch via the LAN, as shown in Figure 2-5.
