Environment : This article applies to all controller models and AOS versions 5.0 and higher. The configuration and verification steps mentioned in this article are tested on Aruba 3200XM Mobility Controller running AOS version 6.3.0.0.
The maximum number of users on a guest network at any instance may vary greatly and when it goes to a larger number, chances are that several of those users may concurrently try to do the web based Captive Portal authentication, but there is a configurable soft limit for the number of concurrent sessions that the webserver on the controller can handle and when this soft limit is hit, any new clients will not be presented with the captive portal page. This can be a concern especially on guest networks with large number of clients, on those occasions we shall increase the soft limit from the default value of 25 to any value up to 320.
