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.
Only a few years ago, Cisco tried their hand at a converged access wireless platform with, among other devices, the Cisco 5760 Wireless LAN Controller. To this day, I have nightmares about that box. It wasn’t fully functional, and it had huge code issues. Today, in spite of AireOS being a stable, highly functional, and well-known WLC platform, Cisco is trying it again with a range of WLCs in the 9300 and 9800 series.
However, will this brave attempt prove to have the same fate as the 5760?
