Our production enviroment consists of 3600 controllers and mainly AP-105s. After the installation of 6.2.0.2 from 6.1.3.3 and the problem starded:
1) Controllers started to randomly blacklist clients. All blacklist options are disabled and we haven't use client blacklisting in any situtation before. The reason is "IP Spoofing" although I disabled both " Prohibit IP Spoofing" and "Prohibit ARP Spoofing".
I remember that somebody else mentioned this same issue.
2) Problems with Apple Macs. Many users have complained that their macbooks or airs are dropping connections, when using 802.1x/eap with wpa2. Also there has been issues when roaming ap to ap with these devices.
When debugging one of these devices I found:
Deauth to sta: <macbookpro> Ageout AP <ap> Ptk Challenge Failed
Deauth from sta: <macbookpro> AP <ap> Reason Ptk Challenge Failed
Any comments on that? This problem also came out after the 6.2. update.
It would be nice to know if others are facing these same issues. Eagerly waiting for 6.2.0.3... :smileyindifferent:
