Do I need to keep controller running when using portal authentication?

Suitable for: EAP Controller 2.4.4 or higher and EAP series with corresponding firmware

Available portal authentication methods in EAP Controller are No Authentication, Simple Password, Hotspot, External Radius Server and External Portal server. If you are not familiar with the configuration please refer to FAQ 896

After the configuration, you may raise the question whether you should keep the EAP controller running. The simple answer is that to make the most use of portal authentication, you should keep it running.

The table below compares the behaviors of each authentication type when controller is online with that when controller is offline.

Authentication Type

controller Online

controller Offline

No Authentication

  • Portal page provided by EAP Controller
  • Authenticated by EAP Controller
  • Portal page provided by EAP
  • Authenticated by EAP

Simple Password

  • Portal page provided by EAP Controller
  • Authenticated by EAP Controller
  • Portal page provided by EAP
  • Authenticated by EAP

Hotspot

  • Portal page provided by EAP Controller
  • Authenticated by EAP Controller
  • No longer provide authentication
  • Clients keep the previous authentication states

External Radius Server

  • Portal page provided by EAP controller or external web portal
  • Authenticated by radius server
  • Portal page provided by EAP or external web portal
  • Authenticated by radius server

External Portal Server

Portal page and authentication both provided by portal server

  • No longer provide authentication
  • Clients keep the previous authentication states
 

Summary:

  1. For Hotspot and External Portal Server authentication the controller should stay running, or it would no longer provide authentication, and all client keep the previous authenticated states. Clients who pass the authentication before the Controller down could access the Internet while the rest client devices have no means to finish the authentication and access the internet.
  2. For other authentication types, it works to some extent when EAP controller is offline. But the client will not be able to see the customized logo and background image. When client moves from one EAP to another, the portal page will pop out again even the authentication do not “time out”. So, to make the best use of portal authentication, you had better to keep the controller running.
