This controls how MAC addresses are authenticated.
papUsernameAsMacAddress(1)
Authentication uses the RADIUS server by
sending a PAP request with Username and
Password both equal to the MAC address being
authenticated. This is the default.
papUsernameFixed(2)
Authentication uses the RADIUS server by
sending a PAP request with Username and
Password coming from the h3cSecureRalmAuthUsername and
h3cSecureRalmAuthPassword MIB objects. In this mode
the RADIUS server would normally take into account
the request's calling-station-id attribute, which is
the MAC address of the host being authenticated.
