Deploying the new Cisco 9800-CL wireless controller is fast and easy, and by using the built-in workflows, a new wireless network can be deployed in only a few minutes. In this post, I’ll review how to deploy the virtual wireless LAN controller in VMware ESXi and stand up a very simple WLAN. We’ll also take a look at some potential gotchas and some noteworthy differences between how the new WLC is configured compared to the AireOS WLC.
Why aren’t our wired LANs more like WLANs? Wireless vendors have already been doing for years what switch manufacturers are only starting to get into in the last couple years. A rough comparison of a few attributes of typical wired and wireless networks shows striking differences in how we manage our LANs and WLANs.
