Guru Guys,
Tell us how to tune up the switches side about all this details please, a good thing could be do it in 2 divisions:
1.-General concept (seems like al ready we had comment about it...), how to be sure (commands) about where is the problem (switch side or controler/ap aruba side)... few commands or console debug or packet captures... something to check keywords?.
2.-Paste example config of Aruba side and few switches side (Cisco, Extreme, Avaya, etc..).
btw: We use "best practices"... meanning: We check the release notes of new pre-releases and GA releases, we only just use GA in production as TAC recommend us and we work with workarounds on issues too...
Best regards.
