7.3 Authentication for a VNS
The next step in configuring a VNS is to set up the authentication mechanism. There are 
various authentication combinations available:
● If network assignment is by SSID, authentication can be:
● none
● by Captive Portal using internal Captive Portal
● by Captive Portal using external Captive Portal
● by MAC-based authentication
● If network assignment is by AAA (802.1x), authentication can be:
● by 802.1x authentication, the wireless device user must be authenticated before 
gaining network access
● by MAC-based authentication
The first step for any type of authentication is to select RADIUS servers for:
● Authentication
● Accounting
● MAC-based authentication
MAC-based authentication enables network access to be restricted to specific devices by MAC 
address. In addition to the other types of authentication, when MAC-based authentication is 
employed the HiPath Wireless Controller queries a RADIUS server to determine if the wireless 
client's MAC address is authorized to access the network.
