Hi Daniel0524 and cjoseph & anyone who reads this comment.
I'm a field System Engineer from an Aruba Networks partner in Mexico City, I have the ACMA, ACMP certifications, so I've made Design, Implementation & L2 support to Aruba Infrastructure across some companies.
So, I have the same problem that Daniel0524 has, Í don't know if there is a coincidence but I have these problem only in two projects using 600 series controllers with 6.1.3.X OS Version, both with mixed 105 & 135 AP's, (I've tried 6.1.3.4, 6.1.3.5, 6.1.3.6 & 6.1.3.7 OS versions with exactly the same problem). In both cases I only had two SSID's (employee & guest). Employee uses 802.1X, WPA2 Entreprise, AES, with external radius in windows 2008. Guest uses Captive portal & Internal Database. In both environments I use separate vlans for each SSID. In environments who uses 5.X.X.X OS versions, all works just fine, no issues, whit exactly the same configuration.
I've made some research and apply all the recomendations from cjoseph, "drop broadcast & Multicast" separate vlans for wired & wireless clients, and other recomendations from cjoseph founded here in Airheads. but the problem continues.
Since I don´t administrate these 2 environments I didn´t open a case to Aruba TAC Support. I only want to know if Daniel 0524 Open A TAC case & if Aruba Support solved his issue and how it solve it.
Thanks for your support & sorry if I wrote somthing wrong cause english its not my primary language.
Regards.
