| ====== Access-Request format for the PPPoE networks ====== | |
| {{indexmenu_n>1}} | |
| Access-Request request being formed by the fastpcrf contains the following Radius attributes: | |
| * ''User-Name'' - for the PAP/CHAP/MS-CHAPv2: subscriber login. In order to authorize by MAC address this attribute contains the subscriber MAC address as a string, similar to the Calling-Station-Id attribute. | |
| * ''Password'' - subscriber password (only for the PAP authorization) | |
| * ''CHAP-Challenge'' and ''CHAPPassword''- for the CHAP authorization | |
| * ''MS_CHAP_Challenge'' and ''MS_CHAP2_Response'' (Microsoft VSA) - for the MS-CHAPv2 authorization | |
| * ''Calling-Station-Id'' - subscriber MAC address as a string, for example, '01:02:e4:55:da:f5'. Here, the small letters for hex-digits A-F are used. | |
| * ''Acct-Session-Id'' - accounting sesson identifier. This attribute is always passed even if you do not use the VAS Experts DPI accounting. | |
| * ''Service-Type'' = 2 (Framed) | |
| * ''Framed-Protocol'' = 1 (PPP) | |
| |
| [SSG 7.6+] If Access-Request is initiated by the | |
| [[en:dpi:bras_bng:radius_integration:radius_auth_server_integration:radius_auth_coa:start|CoA request of reauthorization]], | |
| then the ''Framed-IP-Address'' attribute containing the subscriber IP address is added. | |
| |
| Attributes identifying the NAS (i.e., VAS Experts DPI): | |
| |
| ''NAS-IP-Address'' - NAS IP address is specified in the fastpcrf.conf by the ''radius_attr_nas_ip_address'' configuration option. | |
| If this option is not specified in the fastpcrf.conf, the NAS-IP-Address attribute will not be added to the Access-Request. | |
| | |
| ''NAS-Identifier'' - NAS identifier is specified in the fastpcrf.conf by the ''radius_attr_nas_id'' configuration option. | |
| If this option is not specified in the fastpcrf.conf, the NAS-IP-Address attribute will not be added to the Access-Request. | |
| | |
| Note that only one of the attributes - NAS-IP-Address or NAS-Identifier is added to the Access-Request depending on the fastpcrf.conf settings. If both radius_attr_nas_ip_address and radius_attr_nas_id options are specified in the fastpcrf.conf, the only NAS-IP-Address is included in the Access-Request. The radius_add_all_nas_ids parameter allows you to add both of these attributes to the request: | |
| <code># Allows to add NAS-IP-Address AND NAS-Identifier | |
| # By RFC, the request can include either NAS-IP-Address or NAS-Identifier. | |
| # If both options are specified then priority is given to NAS-IP-Address option. | |
| # The value of this parameter 1 allows you to add both attributes to the request. | |
| #radius_add_all_nas_ids=0</code> | |
| |
| ''VASExperts-Service-Type'' - Vendor-Specific attribute containing the number (int32) defining the PPPoE authorization type: | |
| * VASExperts-Service-Type = 2 - for the PAP | |
| * VASExperts-Service-Type = 3 - for the CHAP | |
| * VASExperts-Service-Type = 4 - for the MS-CHAPv2 | |
| * VASExperts-Service-Type = 5 - for the MAC address authorization | |
| |
| ''Message-Authenticator'' - [RFC2869] is formed if the ''radius_msg_auth_attr = 1'' options is specified in the fastpcrf.conf | |
| |
| If the incoming subscriber packet contains VLANs (that is, if you have a PPPoE network with L2 VLAN tags): | |
| * ''NAS-Port-Type'' - is specified in the fastpcrf.conf by the ''radius_attr_nas_port_type'' configuration option, its default value is 5 (Virtual) | |
| * ''NAS-Port'' - VLAN value | |
| * | |
| If the incoming subscriber package contains Q-in-Q (that is, if you have a PPPoE network with L2-QinQ tags): | |
| * ''NAS-Port-Type'' - is specified in the fastpcrf.conf by the ''radius_attr_nas_port_type'' configuration option, its default value is 5 (Virtual) | |
| * ''NAS-Port-Id'' - VLAN value as a string using like "outerVLAN/innerVLAN" format, for example, "10/102" | |
| |
| =====Supports PPPoE circuit-id and remote-id options===== | |
| |
| SSG as of version 8.2 supports the PPPoE options circit-id and remote-id according to [[https://tools.ietf.org/html/rfc4679|RFC 4679]]. The values of these options are passed to Access-Request in the VSA attributes ''Agent-Circuit-Id'' and ''Agent-Remote-Id'' respectively, vendor-id=3561. | |
| |
| =====Support Huawei vendor-specific tag 1===== | |
| |
| SSG 12.4 - added support for Huawei vendor-specific tag 1. | |
| |
| The value is interpreted as ''ADSL-Forum-Circuit-Id''. | |
| |
| If PPPoE packet contains ''Circuit-Id'' and ''Huawei tag 1'', ''Circuit-Id'' is preferred, ''Huawei tag 1'' is ignored. | |
