A lot of these magic sauce features e.g. FRA, have expectations/dependencies on other services like DCA operating at current best-practices. If you’ve been running a Cisco solution for years, a well-meaning admin may have tweaked them for any number of reasons. If those settings aren’t reviewed with each new major code version, you wind up defeating the new features. For example, I find that many people have changed DCA’s scheduled run time from its default of 10 minutes to hours or disabled it altogether. FRA is dependent on DCA, and is most effective when DCA is back at its default.

We are presently using 40mhz as a standard with 20mhz for dense deployments. Not quite in the same vein, but we actually decided to leave this alone and go towards tuning out 2.4 and making use of FRA more. We are not doing the automagic FRA, but rather manually switching radios over to either 5.8 or monitor mode.

In practice students kept getting bounced because of width changes so I removed it an I am using 20Mhz channels only.

We have been advised to use 20Mhz as a campus wide setting, however DBS appears to offer significant benefits that would allow us to make better use of our 802.11ac AP’s. We are currently running two 8540 WLC’s with around 2,500 access points with a mix of 3600 – 3700 -3800 and 1810 access points.
