Telnet Connection
Establishment
Telneting to a Switch
from a Terminal
You can Telnet to a switch and then to configure the switch if the interface of the
management VLAN of the switch is assigned an IP address. To assign an IP address to
the interface of the management VLAN of a switch, you can log into the switch
through its Console port, enter VLAN interface view, and execute the
ip address
command.
Following are procedures to establish a Telnet connection to a switch:
1 Configure the user name and password for Telnet on the switch. Refer to “Telnet
Configuration with Authentication Mode Being None”, “Telnet Configuration with
Authentication Mode Being Password”, and “Telnet Configuration with
Authentication Mode Being Scheme” for more.
2 Connect your PC to the Switch, as shown in Figure 33. Make sure the Ethernet port
to which your PC is connected belongs to the management VLAN of the switch and
the route between your PC and the switch is available.
