In this article, we will point out two important caveats that you need to be aware of in order to have a vWLC setup and functioning correctly. Well, this is very true as long as you have thoroughly reviewed the vWLC Deployment Guide and understand all the requirements and limitations, otherwise, you may find out the hard way that things may not work the way you expected them to. For those of you who like to lab, like myself, but always have difficulty getting your hands on a WLC, this may seems like a great news that you can now have a WLC readily available for testing. Your first thought might be less hardware cost and a WLC can take all the advantages of being a VM. Cisco has released a Virtual Wireless LAN Controller (vWLC), a VM version of a controller that has always been an appliance or hardware module, with 60-day evaluation at installation.
