Today we returned after the Christmas holiday and started to connect the router and set it up with ours configuration.
To change the configuration on a router we need to connect the router with a pc with a console (serial) cable.
We use a program called putty that lets us open the commando prompt of the Router. Choose Serial and it should automatically find the com port you have the cable inserted to.
Now that we are connected to the router we need to reset it to factory default.
The first command you will see will be something like:
Router>
To reset it you need to type:
Router>erase startup-config
The router should be ready for a new setup.
To setup a new configuration we first need to enable the router, to do that type:
Router>enable
And it should change to:
Router#
Now we need to enter configuration mode, to do this type:
Router#conf t
Now it should look like this:
Router(config)#
Now we need to go to the interface to setup the information, so check what port you have plugged the network cable into, in our case its Serial 0/0. So in the commando prompt type:
Router(config)#interface serial 0/0
You are now on that interface and it should now look like this:
Router(config-if)#
The next thing to do is to give it an IP address and a Subnet Mask. So type in the IP and Subnet you have chosen. In our case we typed this:
(Don’t type space by the way)
Router(config-if)#198.162.2.14 <space> 255.255.255.240
The final thing to do is to make sure that the serial line don’t go down, to do this type:
Router(config-if)#no shutdown
To check if everything is as it should be type:
Router(config-if)#exit
Router(config)#exit
Router#show running-config
Don’t worry that if the information says that the line protocol is down, the router first need to be connected to another router for a protocol to be up.
