RE: [WIRELESS-LAN] 802.11r
To me is another one of those potentially really good features that has just been horribly bungled by Wi-Fi Alliance and vendors. As long as the client base is as horribly capability- fragmented as it is, things like 11r are somewhere betwee a huge gamble and fairly impractical in our environments (at least for prod). Says I.

RE: [WIRELESS-LAN] 802.11r
We turned it on for our primary SSID in Cisco code 7.6.130.0 for roughly 4 hours and it was an absolute NIGHTMARE. All device types were unpredictable and unstable. About a third of our 20,000 user devices wouldn't connect at all, the ones that did would frequently drop off the network. Once we disabled it, roughly half of the machines that were able to connect while 802.11r was enabled were suddenly NOT able to connect after the rollback. Those users had to forget the network and or delete the profile from their devices before they could connect again. It made for an interesting day and a half.

Re: [WIRELESS-LAN] 802.11r
According to Cisco's Best Practices site, they do recommend enabling 802.11r, with the following very important caveat: *Note*http://www.cisco.com/c/dam/en/us/td/i/templates/blank.gifNon 802.11r clients will *not *be able to connect to this WLAN. Ensure that the clients are 802.11r capable, for example, Apple devices on version 6 and above. http://www.cisco.com/c/en/us/td/docs/wireless/technology/wlc/8-0/82463-wlc-config-best-practice.html#pgfId-380025 -dan Dan Brisson Network Engineer University of Vermont On 7/1/2015 9:55 AM, Kevin McCormick wrote: I know Cisco has added 802.11r so devices can optional use 802.11r if supported starting with version 8.0. I have been looking forward to using version 8.0, but the number of caveats has kept us away. With version 7.6 802.11r is an all or nothing feature requiring you to create an extra SSID, which we have not done and will not do. I am also curious about the experience of others.

Re: [WIRELESS-LAN] 802.11r
We've had to enable it to get iPads to roam properly on a WPA2/EAP/MSChapV2 network. iPads and Macbooks work, so far we haven't found any other device that will associate successfully with 802.11r enabled (but we haven't tried too many, just a few Dell laptops and Android devices.) We obviously had to create a new SSID for this, and made it 5 GHz only. Here's an Apple article on their recommended settings that we followed: https://support.apple.com/en-us/HT203068 -- Toivo Voll On Wed, Jul 1, 2015 at 8:51 AM, Jerry Bucklaew j...@buffalo.edu wrote: To ALL: I was just wondering if anyone has taken the plunge and enabled 802.11r on their WLAN and if they had any fall out?
