Involved Network Elements

Table 7-1  Components involved in PPPoE networking


Product Model


AAA server

Huawei servers or third-party AAA servers

Performs authentication, accounting, and authorization on users.


When Huawei's Agile Controller-Campus functions as the server, the version required is V100R001, V100R002, V100R003.

If a Huawei switch needs to function as a DHCP server and assign IP addresses to terminals based on the static MAC-IP binding relationship delivered by the Agile Controller-Campus, the switch must run V200R009C00 or a later version, and the Agile Controller-Campus must run V100R002 or V100R003 version.

Licensing Requirements

A PPPoE resource License is available to extend the number of PPPoE access users. By default, the device supports 256 PPPoE users. You can load the License to extend the number of PPPoE access users.

For details about how to apply for a license, see S Series Switch License Use Guide.

Feature Limitations

  • The switch can function only as a PPPoE server, can have PPPoE configured only on the VLANIF interfaces of X series cards, and allows only wired IPv4 users to access using PPPoE. When users use Windows 7 or later as the PPPoE client to access, to prevent the access speed from being affected, do not select the IPv6 option of the client network connection attribute.
  • The XGE interface connected to ET1D2IPS0S00, ET1D2FW00S00, ET1D2FW00S01, or ET1D2FW00S02 does not support PPPoE.
  • PPPoE cannot be used together with super VLAN, VLAN mapping, or VLAN stacking.
  • PPPoE users cannot be bound to VPN instance, and do not support NetStream, IP Multicast, and QinQ.
  • The address delivered by RADIUS server must be in the same subnet with the VT interface address.
  • After Portal authentication and MAC address authentication are configured on a VLANIF interface, PPPoE authentication cannot be configured on the interface.

  • The number of PPPoE authentication access users is limited by route specifications and cannot exceed the upper limit. It is recommended that the route specifications on the network be greater than the PPPoE user specifications on the device.

  • In versions earlier than V200R009C00, when the device uses the IP address negotiation function of PPP to allocate IP addresses to users, it determines IP addresses to be allocated based on the users' MAC addresses. In V200R009C00 and later versions, the device determines IP addresses to be allocated based on the users' MAC addresses and session IDs in the PPP negotiation stage. If a user goes online twice, the generated session IDs may be different. As a result, the device may allocate a different IP address to the user each time the user goes online.
