Does anyone know how to wipe & configure a Cisco AP?
This among many other questions would arise at my last company. There was not a single engineer that knew how to configure & support the Wireless infrastructure that we had. We had some contractors that came in, set up the vWLC and the environment and left without providing any documentation. So there was the platform, comprising of vWLC with 38 Access Points associated to it. So what do we do next?
This is where it started for me..
I wanted to learn the basics of WiFi, to learn more about the standards, how RF propogates, why do we get bad signal? How can I help fix these issues etc? I liked the fact that no-one else had any interest in it and this was my niche to support. So I found an introductory course called Certired Wireless Technology Specialist, by a programme called CWNP – which I highly recommend. This gave me the basic understanding of how Wireless works and sparked the start of my journey into Wireless.
However, this course would not give me the skills I needed to configure a Cisco WLC or any related products as it is vendor neutral. So for me there was a lot of research and trying to work things out myself. I had also started studying for the CWNA exam (also by CWNP) which helped a lot and then I realised that my CCNA Routing & Switching qualification was about to expire, so in came CCNA Wireless! I decided to go for it.
What did I use to study?
I used the official study guide by David Hucaby which can be found here: CCNA Wireless Official Study Guide
This was a good start, it gave me a great insight into Wireless, Cisco style! I had not seen multiple WLC architectures before and did not have any concept of how these worked. I did not know about Flex Connect or the many features that Cisco offer, so this was a very valuable start!
The main reason for this post is a word of warning for engineers looking to take this exam. This book provides 50% of what you need to know to pass the exam. It’s a bit crazy but Cisco’s Official Cert Guide does not cover everything you need. My advice would be to download the exam objectives for the exam: WIFUND Objectives
Go through each area and ensure you know a lot about each subject. You will definitely get tested on it. All of the exam objectives were in my exam. So study hard and get researching online.
The other useful resources I used were blogs, Cisco white papers & the CWNA Study Book. The CWNA book is particular good for explaining the rule of 10's and 3's and provides great examples to a) understand it properly and b) test yourself on your math with various scenearios to calculate. Also for all the forms of EAP. You can find that here: CWNA 107
All the information you need is out there to pass, just don’t rely on the book!
Best of luck if you are taking the CCNA Wireless soon :-)
