| 1 | User-NameUsername of the PPPoE client to be authenticated. | x | ||
| 2 | User-PasswordUser password (PAP) of the PPPoE client to be authenticated. | x | ||
| 3 | CHAP-PasswordValue transmitted by the PPPoE client as part of password authentication in the case of CHAP. | x | ||
| 4 | NAS-IP-AddressTransmits the IPv4 address of the NAS/PPPoE server. | x | ||
| 6 | Service-TypeSpecifies the service type that the device requests or expects in response. For PPPoE, the service type is "Framed-User". | x | ||
| 7 | Framed-ProtocolSpecifies which protocol is used. The PPPoE server transmits the value "PPP". | x | ||
| 8 | Framed-IP-AddressDefines the IPv4 address to be assigned to the PPPoE client via IPCP. | x | Framed-IP-Address=100.64.1.2 | |
| 18 | Reply-MessageMessage transmitted to the PPPoE client by the PPPoE server in a PAP Authenticate-ACK or CHAP-Success. | x | ||
| 30 | Called-Station-IDTransmits the device name of the router/NAS. | x | ||
| 31 | Calling-Station-IDSpecifies the ID of the calling station. For PPPoE, the MAC address of the client is transmitted. | x | ||
| 32 | NAS-IdentifierSpecifies the device name of the NAS/PPPoE server. | x | ||
| 61 | NAS-Port-TypeSpecifies the physical port through which the device authenticates the user. For PPPoE, the type "Ethernet" is transmitted. | x | ||
| 80 | Message-AuthenticatorAdditional attribute to protect the integrity of the RADIUS message exchange and prevent message spoofing. The attributes are set automatically. | x | x | |
