Configuration

On this page I am going to show how configuration is done on a switch or router.

Setup Configuration

 

To start we are going to look at the Cisco Catalyst 2950 series of switch’s. Before entering the interface, we need to ensure the switch is connected to the end device correctly. We need a cable plugged from the console port of the switch, tot he USB port of an end device (a computer or laptop).

 

To create a connection we need to open PuTTY on our end device.

 

putty configuration

 

We need to click on serial, then enter which serial line destination we want to connect to. Then click on open.

To know which switch we are using, we need to create a hostname. To do this we need to work in configuration mode. With the following commands we can enter this mode.

Switch>

Switch>enable

Switch#

Switch#configure terminal

Switch (config) #

With Switch (config) # we now know we have entered the configuration mode. The next thing we need to do is create our hostname, for this example I will use my own name. To put our picked name onto the server we use the command hostname as follows:

Switch (config) #hostname Debra1

Debra1 (config) #

With our server name established we now need to make it secure. By creating and adding a password onto the server, we add a layer of security onto it. We do this still in configuration mode, there are two commands that can be used. The enable password command will save the password, but will make it easier for hackers to learn it. The enable secret command will still save the password, but then encrypts it making it difficult for someone to hack the server. We enter the password straight after the command and save it on the next line as shown below .

Debra1 (config) #enable secret (enter chosen password)

Debra1 (config) #exit
