Hi Christina, What we see with our IPv6 wireless:
1. SLAAC hands out addresses, you can join. 2. While running pings PCs and older MACS the pings will dropout and only High Sierra will come back after about 4-6 pings with a new address. We ran some captures over the air and full communication appears to stop from the AP (not being a client based issue). We have a case open with TAC and we are pretty sure we hit a bug. We are looking forward to stable 8.5 code. Best of luck with the issue! -Jamie Jamie Price │Senior Network Engineer 303.724.8970| jamie.pr...@ucdenver.edu 1945 N Wheeling Street, MS F408, Denver, CO, US 80045 From: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Brady J.

For about a year we have been running that code. And strangely enough, we have had issues with iOS not staying connected when roaming. As all modern systems try IPv6 before IPv4, if there is an issue with IPv6, this would explain the delay.

We are running 802.11k/v/r and it has made a tremendous difference in our roaming (and many less complaints). We have an IPv6 issue with 8.3.133.0 with IPv6. On PCs, it times out. On MACs it times out and recovers. This is not a production network- but it will be once we can find code without this bug. Otherwise 8.3.133.0 has been great.

We utilize Cisco WLC 8540's (2 HA pairs), Cisco APs (mostly 3702's) and Cisco ISE for portals, authentication and authorization. We were seeing the ISE authentication service jump up in latency and we would get calls that users could not connect to eduroam. We have determined that our size and number of authentications, particularly at each class change event, are such that we should be using hardware load balancing. We are in process of setting that up but each class transition results in a short period where authentication latency can get to be a problem and users have a less than desirable experience. During the time we are building this out our engineers are wanting to enable 802.11R (Fast Transition) on our controllers. We currently do not support this feature on the WLCs. We are running 8.2.166.0 code on our WLCs and we have heard other have issues with this code release. While we are not experiencing the same results or hitting the same bugs, I am concerned that turning on this feature might have ramifications related to the code release we are running. My question to the group is who has used 802.11R and would you be willing to shoot me a private message with configuration and/or your results?
