3-2Telnet Connection EstablishmentTelnetting to a Switch from a TerminalYou can telnet to a switch and then configure the switch if the interface of the management VLAN of theswitch 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 IPaddress to the management VLAN interface of the switch.z Connect to the Console port. Refer to Setting Up the Connection to the Console Port.z Execute the following commands in the terminal window to enable the Telnet server function andassign 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 as202.38.160.92, and .the subnet mask as 255.255.255.0. system-view[Sysname] telnet server enable[Sysname] interface vlan-interface 1[Sysname-Vlan-interface1] ip address 202.38.160.92 255.255.255.0Step 2: Before Telnet users can log in to the switch, corresponding configurations should have beenperformed on the switch according to different authentication modes for them. Refer to TelnetConfiguration with Authentication Mode Being None, Telnet Configuration with Authentication ModeBeing Password, and Telnet Configuration with Authentication Mode Being Scheme for details. Bydefault, Telnet users need to pass the password authentication to login.Step 3: Connect your PC to the Switch, as shown in Figure 3-1. Make sure the Ethernet port to whichyour PC is connected belongs to the management VLAN of the switch and the route between your PCand the switch is available.Figure 3-1 Network diagram for Telnet connection establishmentConfiguration PCrunning TelnetEthernetWorkstationServerWorkstationEthernet portStep 4: Launch Telnet on your PC, with the IP address of the management VLAN interface of the switchas the parameter, as shown in the following figure.
