2 CONFIGURING DIALUP
2.1 PPPoE Dialup
2.1.1
PPPoE Overview
Qtech Device supports PPP running on the Ethernet (PPPoE, PPP over Ethernet) interface for DDR. Its
characteristics are like the DDR: stimulating dialup if there is data communication and automatically disconnecting
the line when it is idle for the specified period.
The PPPoE implementation on Qtech devices is similar to DDR Profiles, which binds the Ethernet interface to the
logical interface and performs the negotiations on the logical interface.
2.1.2
PPPoE Configuration Tasks
From the implementation of PPPoE, the PPPoE configuration tasks include:

Configuring the Ethernet interface

Configuring the logical interface

Configuring the necessary global parameters
2.1.2.1 Configuring the Ethernet interface
The configuration of the Ethernet interface includes:

Enable the PPPoE on the interface

Bind the Ethernet interface to the specified dialer pool
Some basic configurations of the Ethernet interface are also required, such as the interface activation ( no
shutdown ).
Use the following command to enable PPPoE on the Ethernet interface in interface configuration mode.
Command Function
Qtech(config-if)# pppoe enable
Enables PPPoE.
Since PPPoE is implemented via DDR Profiles, it is required to bind the Ethernet interface to the specified dialer pool
available for the use of the logical interface in DDR Profiles. Use the following commands to bind the Ethernet
interface to the specified dialer pool in interface configuration mode.
Command Function
Qtech(config-if)# pppoe-client dial-pool-number pool-
number dial-on-demand
Binds the Ethernet interface to the specified logical
dialer pool (to enable the DDR function. The dialup to
the PPPoE server is activated only when there is some
message).
Qtech(config-if)# pppoe-client dial-pool-number pool-
number no-ddr
Binds the Ethernet interface to the specified logical
dialer pool (to enable automatic dialup to the PPPoE
server).
One of dial-on-demand and no-ddr must be selected. dial-on-demand enables the PPPoE DDR function to
disconnect the line when the specified idle period expires; no-ddr enables the PPPoE auto-dialup
function to dial to the PPPoE server automatically.
2.1.2.2 Configuring the logical interface
All PPP negotiations of the PPPoE dialup are based on the logical interface, so it is required to configure the PPPoE
dialup related parameters on the logical interfaces.
Use the following commands to configure the logical interface in global configuration mode.
