CISCO DEVICES ADMINISTRATION AND CONFIGURATION

The CCNA exam does not test your product-specific knowledge. So you are not expected to know what feature cards are available for a Layer 3 series switch, but you do need to understand the differences between a router and a switch, and you need to understand how their configuration requirements vary.

This section introduces you to Cisco equipment. In this section you will learn how to connect to it and make initial configurations, as well as how to connect it to other devices to build a network. You will review the different types of network connections available, with particular emphasis on those that are tested in the CCNA exams. You will also look at where a Cisco device stores the various files it needs to operate, the files needed for the boot process, and the backup and restoration of system files

For our purposes, we use a Catalyst 2960 or 3560 switch and a 1600, 1700, or 2600 series router as example devices. Most of the commands you learn in this section also apply to more advanced models.

Cisco devices are very costly. For exam preparation you could use simulators. Several simulators are available choose one that best suites you. We would packet tracer for configuration.

2. How to connect with cisco devices:-

In this lab scenario I will demonstrate that how can you connect with a Cisco router. To connect physical Cisco device you need a console cable. Attach cable to com port on computer and other end to console port of Cisco devices.

Console Port

When you first obtain a new Cisco device, it won't be configured. That is to say, it will not do any of the customized functions you might need; it does not have any IP addresses, and it is generally not going to do what you paid for. Routers need basic configuration to function on a network. The console port is used for local management connections. This means that you must be able to physically reach the console port with a cable that is typically about six feet long. The console port looks exactly like an Ethernet port.

Once you have proper console cable follow this path

Now on computer click on stat button ==> program = = > accessories == > communications == > hyper terminal == > location information == > cancel == > Confirm cancel == > yes == > hyper terminal == > OK Connection Descriptions == > Vinita == > OK == > location information == > confirm cancel == > yes == > hyper terminal == > connect to == > OK == > Port Settings == > Do setting as Given Below and press OK.

If you still have problem in configuring hyper terminal or you do not have hyper terminal options in accessories you can use this tiny software. With this software you can connect with any devices that support Telnet, SSH, Rlogin, console connections. This is ready to use software. Download it and execute it. Select Serial sub key from Session main key and rest it will do automatically.

How to connect with router in Boson Simulator:-

If you use Boson simulator for CCNA practical then select erouter from tools menu and select router from available list. ( Device only be available when any topology will be loaded in simulator. Use Boson Network designer to create topology.)

How to connect with router in packet tracer:- First create a desire topology by dragging devices to workspace. Once you have created topology configurations in packet tracer is straight forward. To Configure any device double click on it and select CLI.
