| | ====== Access-Accept format for the PPPoE networks ====== |
| | {{indexmenu_n>2}} |
| | The Access-Accept response means that the subscriber is authorized, the balance is sufficient, and he is assigned an IP address. |
| | Attributes: |
| | * ''Framed-IP-Address'' - is mandatory one: the IP address assigned to the subscriber. |
| | * ''Idle-Timeout'' - is optional one: idle timeout, in seconds. The PPPoE session will be terminated if there is no packets being transferred from/to the subscriber during this time. If this attribute is not specified, the session is considered to be unlimited (until it is explicitly terminated by the subscriber) |
| | * ''Reply-Message'' - is optional one: message to be sent to the subscriber in the PPP Auth-Ack response |
| | * ''Session-Timeout'' - is optional one: max session lifetime, in seconds |
| | * ''Acct-Interim-Interval'' - is optional one: the period the accounting intermediate data to be sent, in seconds (can not be less than 60). 0 - do not send accounting intermediate data. |
| | * ''Class'' - is optional one: if this attribute is specified then it will be sent "as is" in all the accounting packets |
| | * ''MS-CHAP2-Success'' - Microsoft VSA attribute [RFC2548], is mandatory for the MS-CHAPv2 authorization |
| | |
| | Поддерживаются следующие VSA-атрибуты Microsoft (vendor-id=311, RFC2548), все они не являются обязательными: |
| | * ''MS-Primary-DNS-Server'' - the IP address of the primary DNS server |
| | * ''MS-Secondary-DNS-Server'' - the IP address of the secondary DNS server |
| | * ''MS-Primary-NBNS-Server'' - the IP address of the primary NetBios server |
| | * ''MS-Secondary-NBNS-Server'' - the IP address of the secondary NetBios server |
| | |
| | VASExperts VSA attributes (vendor-id=43823) are not mandatory: |
| | |
| | [41] ''VASExperts-DHCP-DNS'' - the IP address of the DNS server. There can be no more than two VASExperts-DHCP-DNS attributes: one for the primary DNS server and one for the secondary one. |
| | |
| | DNS server addresses can be specified through Microsoft VSA-attributes or VASExperts VSA-attributes. |
| | |
| | In addition to the mentioned above attributes, Access-Accept must contain a subscriber policing profile and the activated services list, see [[en:dpi:bras_bng:radius_integration:radius_auth_server_integration:radius_auth_response|subscriber properties attrubutes]] |
| | |
| | == Session lifetime == |
| | If the response doesn't contain the ''Session-Timeout'' attribute, the PPPoE session is considered to be unlimited and will be terminated either by explicit disconnection performed by subscriber or due to inactivity timeout being exceeded. |
| | |
| | If the ''Session-Timeout'' is specified, then the VAS Experts DPI will break the PPPoE session after the expiry of a prescribed period. |
| | The PPPoE session break is clearly described in the PPP/PPPoE specifications and consists in sending special term messages to the subscriber; the subscriber, having received term, can create a new PPPoE-session. |
