First, you want to access the router through Telnet, you need to first configure the router through the console port, such as IP address, password, etc.


For example, I set up an experimental topology ( It is important to note that the PC and the router to connect with the intersection, and then enter the interface mode to activate the port, the image shows the green point as the normal activation port )

Small inserts (knowing that these operations are needed first):

PC-Side Required configuration: IP address and subnet mask, gateway

Router requires configuration: (1) Configure Router Ethernet interface IP address

(2) Configure the router password (configure the password to enter the router privileged mode, configure the vty password, that is, the Telnet password)

Note: The IP of the PC and router must be configured on the same network segment


Experimental steps:

(1) Step 1: Configure the Router Ethernet interface IP address

(2) Step 2: Configure the router password

(3) Step 3: Access the router via Telnet


Commands for the relevant steps:

Configure the Router Ethernet interface IP address (enter the privileged mode, global mode, interface mode, and configure the Ip-> activation interface, which, by default, all of the router's interfaces are off), the effect is,

Configure the Router password (enter the router's VTY virtual terminal, configure VTY password-and configure the password to enter the router privileged mode), as the effect,

access the router via Telnet (ping 10.61.100.1 (configured router IP), after successful->telnet 10.61.100.1), the effect is,
