Configuring RADIUS authentication of DHCP sessions

When RADIUS authentication for subscriber sessions is enabled, DHCP messages from subscribers are temporarily held by the BSA, while the user’s credentials are checked on a RADIUS server.

Configuring RADIUS authentication for subscriber sessions is done in two steps:

The following example displays a partial BSA configuration with RADIUS authentication:

        password "mysecretpassword"

            server 1 address 10.100.1.1 secret "radiuskey" 
            retry 3
            timeout 10
        exit    
        re-authentication

    exit    
exit
