5. Select whether Later Login Supersedes Previous. This will allow a secondary form of
authentication to override MAC authentication if necessary, and use the credentials of the
last login to succeed.
See Miscellaneous Options.
Miscellaneous Options
1. In the “Miscellaneous Options” category, Enter a value for the time (in seconds) in the
Default User Idle Timeout field. This value determines how much “idle” time elapses
before the subscriber’s session times out and they must login again.
2. The Access Gateway can reauthenticate “repeat” subscribers who return to the system
within 720 hours. To enable this feature, click on the check box for Enable Automatic
Subscriber Reauthentication
.
3. If you want to enable the URL redirection feature, click on the check box for Enable URL
Redirection
.
4. For a Network Access Server (NAS), if you want to send a NAS identifier with your
account access request, click on the check box for
Send NAS identifier, then define the
NAS identifier in the NAS identifier field.
5. To send the NAS IP address with your account request, click on the check box for Send
NAS IP
.
6. To send a NAS port type with your account request, click on the check box for Send NAS
Port type, then
define the NAS port in the NAS Port Type field.
7. To send the Framed IP address with your account request, click on the check box for Send
Framed IP
.
8. To enable Radius termination action enhancement, click on the check box for Enable
Termination Action Radius Attribute
, then select the percentage (100% - 75%) of the
maximum data volume threshold for which term-action will be enforced (volume-based
sessions only).
This option provides support for Radius Termination-Action for time- and volume-based
subscribers working in conjunction with an external Radius server. Enforcement of this
attribute will result in either:
 logout of the subscriber
 re-authentication of the subscriber through issuance of a new Radius Access-Request
that contains a new Acct-Session ID.
The Radius re-authentication that occurs due to term-action enforcement will be
transparent to the subscriber. This is true for time based sessions that expire, as well.
Radius accounting augmentation will take place as a result of a successful re-
authentication.
