Hi Friends,
Need to discuss a very strange issue with you. we have install Aruba MC3600 with AP135 and AP92. The OS running is 6.1. We have applied Captive Portal with Guest enable mode. The system works perfectly fine from last months but now we are facing very strange issue. Some times Aruba Controller stop showing captive portal page to users, all the connected users got disconnection, and Controller are not respond to ping outside world but strangely new users get IP address from Internal DHCP server but remains in pre authentication role as captive portal page does not show to them. This situations remains for few minutes and than everything becomes fine it self.
We have contacted with ISP to check if internet getting disconnection but they told you are connected from last 72 days. Meanwhile this problem is occurring more and more now. we have face this problem 5 times in last 48 hours.
