Just curious, have any Aruba shops tried enabling EAPOL rate
optimization to try helping with the Apple roaming/dropping issue?
It's a new setting in 6.1 and while it didn't help in my testing,
I've heard others have had success with it. Would someone care to
update with details?
We have had issues with MacOS devices and roaming. Three variables
were suggested - OKC, PMKID, and EAPOL-rate-opt.
We had OKC / PMKID both enabled, no EAPOL-rate-opt, and interval
between ID requests at 30 seconds. Wandering around a well-covered
building with a MacOS laptop pinging a fixed target and it would
disassociate / reassociate / reauthenticate with significant delay in
between; Windows laptop did not have this issue (maybe drop a packet or
two between roaming targets). We tried disabling OKC by itself, but it
seemed to make no difference. This was discussed on the list before so
I'll not repeat the whole issue.
We tried the EAPOL-rate-opt, and we would drop a handful of pings, but
essentially keep a connection intact. So yes, it did appear to help.
It's not 100% still (is anything wireless ever 100%?) but was a solid
improvement over the previous case.
We're still grabbing at straws to improve the mobility, and hoping
perhaps the sticky client voodoo in 6.3 might help the issue as well.
