Enable Telnet Access on Cisco Router

Configuration

Use the following commands to enable telnet access to the router.

First check how many virtual terminal router supports.
(Depending on the router model, the output might be different)

Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#line vty 0 ?
  <1-4>  Last Line number

Enable access to virtual terminals and set the “cisco” as the password to access user mode:

Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login

Enable access to virtual terminals and set the “cisco” as the password to access CONFIG mode:

Router(config)#line vty 0 4
Router(config-line)#login local
Router(config-line)#end

Will use username and password set at congif level:
Router(config)#username [my_username] privilege 15 password [my_password]

Verification

To verify use the following command

Router#show line

Thats it. Now you can access the router remotely using telnet.

Disable telnet:

Router(config)#no line vty 0 4
