Telnet Connection Establishment

Telnetting to a Switch from a Terminal

You can telnet to a switch and then configure the switch if the interface of the management VLAN of the

switch is assigned with an IP address. (By default, VLAN 1 is the management VLAN.)

Following are procedures to establish a Telnet connection to a switch:

Step 1: Log in to the switch through the Console port, enable the Telnet server function and assign an IP

address to the management VLAN interface of the switch.

Connect to the Console port. Refer to

Execute the following commands in the terminal window to enable the Telnet server function and

assign an IP address to the management VLAN interface of the switch.

# Enable the Telnet server function and configure the IP address of the management VLAN interface as

202.38.160.92, and .the subnet mask as 255.255.255.0.

Step 2: Before Telnet users can log in to the switch, corresponding configurations should have been

performed on the switch according to different authentication modes for them. Refer to

, and
