We use a VX9000 with 1200+ AP7522.
RADIUS requests go to a Aruba RADIUS server.
The Proxy mode for RADIUS requests is: "through-centralized-controller" so the VX9000 sends the requests to the RADIUS server.
In a attempt to use a captive portal to authenticate guest users on a guest vlan we noticed that there is a lag.
It takes the VX9000 a minimal of 50 seconds to send the request after the user entered his user/password.
Can anyone shed a light on this. We are stuck.
