Learn how to configure telnet on a switch.We configure telnet services on a switch or a router to access it from anywhere remotely.Suppose you are in London and the switch you want to configure,manage and monitor is in New Delhi then you can monitor and manage your switch remotely through telnet without going physicaly to new delhi.So telnet is basically a remote login program which helps us to manage any device remotely.

Now see in below lab how to configure telnet on a switch.

Configuration on Switch:

Switch>enable

Switch#config t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#hostname S1

S1(config)#interface vlan 1

S1(config-if)#ip address 192.168.1.1 255.255.255.0

S1(config-if)#no shut

S1(config-if)#exit

S1(config)#line vty 0 5

S1(config-line)#password redhat123

S1(config-line)#login

S1(config-line)#
