Tutorial No 1. Communication with router Different connections.

Hello, everyone Today I'm going to explain About how to make connection to router using different approaches. So, here we go. As we know Routers are special computers built to handle internetwork traffic. Routers are very important network infrastructure devices and Router serve many users at same time. The network traffic generated by the end users communicate through the router.We know that There are no input devices for router like a monitor, a keyboard, or a mouse. So Admin has lot of choice to choose from to comminucate with router. Following are methods which admin can use to connect to router.                                     Connection Through using Console Port First method is By connecting the router's console port to a workstation through a console cable. The console port is the management port which is used by admin to log into a router directly-I mean to say that without using a network connection. There are some specification or requirements that need to fulfill to successfully establish connection. First of all You require a terminal emulator application like hyperterminal or Putty (will discuss it later on) to connect to router. Console port connection is a way to connect to the router when a router cannot be accessed over the network. Click the following link to learn how to connect and access a router using console connection. Connection Through AUX Port Second method is By using a remote computer through a modem that calls another modem connected to the router with a cable using the Auxiliary Port on the router. Auxiliary Port (AUX Port) allows a direct, non-network connection to the router, from a remote location. The Auxiliary Port (AUX Port) uses a connector type to which modems can plug into, which gives permission to an administrator from a remote location to access the router like a console port. Connection through protocols telnet, SSH, HTTP,HTTPS Third Method is The routers can be managed over the network by using standard TCP/IP protocols like Telnet, SSH, HTTP that is hyper text transfer protocol or HTTPS that is hyper text transfer protocol secure. Let me tell one thing telnet is device which was developed to manage computers remotely in early days of unix operating systems. A Telnet client and server application ships with Cisco's IOS software and most computer operating systems. SSH is a more secure way to configure routers, since the SSH communication is encrypted. Cisco IOS also has a HTTP server to managed web based communication with the router.
