Configuring hardware wired devices
So, that is enough theory. Now let's proceed with some practice and finally configure the network devices.
We will configure our routers and switches via console ports using a special console cable, which in our case has a RJ-45 connector at one end and a DB-9 connector at the other end. You are unlikely to find DB-9 ports on contemporary computers, thus we need to have a DB-9-USB adapter cable to be able to connect it to a USB port. You can see an example of such a cable and an adapter in the following images from the Cisco website:

Tip
You might need to install special drivers for using an adapter, so please check your adapter's user manual.
Alternatively, you can get a console cable with both RJ-45 and USB connectors, for example, on eBay (http://www.ebay.com/):

We will also need a terminal software to be able to communicate with devices via console ports. On Linux or MAC OS X, you...
