Cisco newer codes version (8.x train) have support for "mixed mode" 802.11r. Which allows non 80211r clients to connect. Removing the need for dual ssid. I have messed with this in lab and in a test building. I had some issues with some clients not being able to connect. Here is little more info and list of some clients that support mixed mode .11r
https://supportforums.cisco.com/discussion/12536231/80211r-mixed-mode-support 802.11d is banned for use in US since Jan. 1 2015. Yes on 802.11h. No issues that I can directly relate to dfs issues. -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Jerry Bucklaew Sent: Wednesday, July 01, 2015 8:51 AM To: [email protected] Subject: Re: [WIRELESS-LAN] 802.11r 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? I know some vendors recommend putting up a second ssid but no one wants to maintain two SSID's. I has been a couple years so maybe the client turnover has solved the issue? I had the same question about 802.11d and 802.11h. I am running an Aruba environment but would be interested in the Cisco side of the house also. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at https://urldefense.proofpoint.com/v2/url?u=http-3A__www.educause.edu_groups_&d=AwICaQ&c=SgMrq23dbjbGX6e0ZsSHgEZX6A4IAf1SO3AJ2bNrHlk&r=rtlMYUF4nwLIYnoG0qXTf9aFc5RLK7DMyf8lTMu__vs&m=zWltbQeiS3meq1msEaByhFEyFDeDYHFPnoqAZWwgF7c&s=uaap2lRI7BkgjHF0-MEVVDptnQkGncUntzEmZ5Y66Rg&e= .
