Cisco CCNA / CCNP Certification Exam: Wiring Your Home Lab





More CCNA and CCNP candidates than ever before have put together their own home laboratories, and there is no better way to learn about Cisco technology than to work with the real thing. However, getting a router and a switch is only part of bringing together the great CCNA / CCNP home laboratory. You have to get the right cable to connect the device, and this is also an important part of your education. After all, without the right cable, the client network will have trouble working!

For your Cisco home laboratory, one important cable is the DTE / DCE cable. This cable has two main uses in a home laboratory. To practice connecting the Cisco router directly through the Serial interface (an important CCNA skill), you must connect it with a DTE / DCE cable. Second, if you plan to use a Cisco router as a frame relay switch in your lab, you will need several DTE / DCE cables to do this. (Visit the Home Lab Help section on my website for examples of Frame Relay sulfur analyzer indonesia switch configurations.)

If you have several switches in your lab, that's good, because you will be able to get many spanning tree (STP) protocols that work and make Etherchannels. To connect your switch, you need a crossover cable.

You will need several direct cables to connect your router to the switch.

Finally, if you are lucky enough to have an access server as part of your lab, you will need an octal cable to connect your AS to other routers and switches in your lab. The octal cable has one large connector at one end and eight numbered RJ-45 connectors at the other end. The large connector must be attached to the async port on your AS, and the numbered RJ-45 connector will connect to the console port on your other routers and switches.

Choosing and connecting the right cables for your Cisco CCNA / CCNP home lab is a great learning experience, and is also an important part of your Cisco education. After all, all the great networks and home laboratories all started at Layer One of the OSI model!
