2.2 Setting Up Configuration Environment Through Telnet

2.2.1 Connecting a PC to the Switch Through Telnet

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 !”.

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.
