I firmly believe that the only way to stay on top of the wireless networking industry is to fully embrace the idea of lifelong learning. To me, this doesn’t just mean learning new skills and products, but also taking the time to revisit and refresh the things you think you already know. That’s why I jumped at the chance to sit in on a three-day Implementing Aruba WLANs course being held at my office. True, I do already have my ACMA, but I attained this back when controllers were running ArubaOS 3.x. Now that ArubaOS 6.x is out, I figured it couldn’t hurt to revisit the course and make sure I’m still up to date. Here are a few observations after completing the first day:
- Regardless of how simple a WLAN controller is to configure, anyone involved in designing, securing, or administering a WLAN must still understand the underlying 802.11 technology. Fancy wizards and snazzy interfaces are great when things are working fine, but don’t expect your WLAN to run as efficiently, securely, or resiliently if you don’t know what all those knobs and dials are actually doing. That beings said, Aruba Networks has done a great job improving and enhancing their configuration wizards. These wizards do such a good job of simplifying the basics of configuring your controller(s) that someone could technically get a secure WLAN up and running with very little wireless knowledge or experience. Unfortunately, there is no WLAN Administration Wizard. Until that day arrives, hit the books and start learning the underlying technology. A good place to look for vendor neutral wireless certification is the CWNP organization.
- Wireless networks are at a critical, and potentially dangerous, juncture in their relatively short lives. If we spend the time to properly plan, design, and secure wireless networks they have the potential to dramatically affect the way we work and play in a very positive and reliable way. However, if we rely too heavily on the perceived simplicity of deploying wireless networks without doing our homework first, then we are setting mobile computing up for failure or, at the very least, an existence that falls very short of the true potential of wireless networking.
Overall, day one was very informative and a lot of fun. It’s always great to see people putting in the time and effort required to properly implement a wireless network. So far the Deploying Aruba WLANs course has delivered what was promised and I am looking forward to sharing my thoughts on the next two days.
