PPPoE, Point-to-Point Protocol over Ethernet, combines PPP protocol and Ethernet to implement access control, authentication, and accounting on clients during an IP address allocation.
The implementation of PPPoE protocol consists of two stages: discovery stage and PPP session stage.
- Discovery stage: The client discovers the access concentrator by identifying the Ethernet MAC address of the access concentrator and establishing a PPPoE session ID.
- PPP session stage: The client and the access concentrator negotiate over PPP. The negotiation procedure is the same with that of a standard PPP negotiation.
Interfaces can be configured as PPPoE clients to accept PPPoE connections.
To create a PPPoE instance, take the following steps:
- Select Network > PPPoE.
In the PPPoE Configuration page, configure as follows.
Option Description PPPoE Name Specifies a name for the PPPoE instance. Interface Select an interface from the drop-down list. User Name Specifies a username. Password Specifies the corresponding password. Conform Password Enter the password again to confirm. Idle Interval Automatic connection. If the PPPoE interface has been idle (no traffic) for a certain period, i.e., the specified idle interval, system will disconnect the Internet connection; if the interface requires Internet access, system will connect to the Internet automatically. The value range is 0 to 10000 minutes. The default value is 30. Reconnect Interval If the PPPoE connection disconnects for any reason for a certain period, i.e. the specified re-connect interval, system will try to re-connect automatically. The value range is 0 to 10000 seconds. The default value is 0, which means the function is disabled. Access Concentrator Specifies a name for the concentrator. Authentication The devices will have to pass PPPoE authentication when trying to connect to a PPPoE server. The supported authentication methods include CHAP, PAP and Any (the default, anyone between CHAP and PAP). To configure a PPPoE authentication method, click the authentication you want to select. The configured authentication must be the same with that configured in the PPPoE server. Netmask Specifies a netmask for the IP address obtained via PPPoE. Distance Specifies a route distance. The value range is 1 to 255. The default value is 1. Weight Specifies a route weight. The value range is 1 to 255. The default value is 1. Service Specifies allowed service. The specified service must be the same with that provided by the PPPoE server. If no service is specified, system will accept any service returned from the server automatically. Static IP You can specify a static IP address and negotiate to use this address to avoid IP change. To specify a static IP address, type it into the Static IP box.
