Cisco Basics Experiment: How to access a router via Telnet

Experiment topology:

Manually set up the PC's IP address by connecting the device through the straight line.

Actions on the router:

router>en
Router#conf ter
Enter configuration commands, one per line. End With cntl/z.

1. Configure Interface IP Address:
Router (config) #int fa0/0
Router (config-if) #ip address 172.16.0.1 255.255.0.0
Router (config-if) #no shut

%link-5-changed:interface fastethernet0/0, CHANGED state to up
%lineproto-5-updown:line protocol on Interface fastethernet0/0, changed
Router (config-if) #end

2. Configure Router Password:

Router#conf ter
Enter configuration commands, one per line. End With cntl/z.
Router (config) #line vty 0 4
Router (config-line) #password Cisco
Router (Config-line) #login
Router (Config-line) #exit
Router (config) #enable password Cisco
Router (config) #end

Actions on the PC:
