Configuration Guide Configuring PPPoE Client
Packet Forwarding
Packet sending process: When a data packet is routed to the dialer interface, the device encapsulates the data packet with
the prepared L2 header information and ultimately sends the data packet from a physical port.
Packet receiving process: After a packet arrives at a physical port, the device marks the Layer 3 (L3) header position of the
packet, executes the next service, and ultimately sends the packet to a host in the intranet.

Configuring the Ethernet Interface
By default, the following functions are disabled and there is no corresponding default value.
Run the pppoe enable command to enable the PPPoE client function on the interface.
Run the no pppoe enable command to disable the PPPoE client function on the interface.
Run the pppoe-client dial-pool-number pool-number dial-on-demand command to bind the Ethernet interface to a specific
logical dialer pool. The logical dialer pool provides on-demand dialing.
Run the no pppoe-client dial-pool-number pool-number command to unbind the Ethernet interface from the specific logical
dialer pool.
Configuring the Logical Interface
By default, the following functions are disabled.
Run the interface dialer dialer-number command to add a specific logical interface and enter the configuration mode of the
logical interface.
Run the no interface dialer dialer-number command to delete the specific logical interface.
Run the ip address negotiate command to configure negotiation-based IP address acquisition.
Run the no ip address negotiate command to remove the configuration of negotiation-based IP address acquisition.
Run the dialer pool number command to associate a dialer pool, which corresponds to the dialer pool configured on the
Ethernet interface.
Run the no dialer pool number command to remove the association with the dialer pool.
Run the encapsulation ppp command to configure the encapsulation protocol PPP. PPPoE is established on the basis of PPP.
Run the no encapsulation command to remove the encapsulation protocol configuration.
Run the mtu 1488 command to set the Maximum Transmit Unit (MTU) to 1488.
Run the no mtu command to remove the MTU configuration.
Run the dialer-group dialer-group-number command to associate a dialer triggering rule, which corresponds to the
dialer-list.
Run the no dialer-group command to remove the configuration of the dialer triggering rule.
Run the ppp chap hostname username command to configure the user name for CHAP authentication.
