Configuring PPPoE Encapsulation on an ATM-over-ADSL or ATM-over-SHDSL Interface

For PPPoE on an ATM-over-ADSL or ATM-over-SHDSL interface, you must configure encapsulation on both the physical and logical interfaces. To configure encapsulation on an ATM-over-ADSL or ATM-over-SHDSL physical interface, use Ethernet over ATM encapsulation. To configure encapsulation on an ATM-over-ADSL or ATM-over-SHDSL logical interface, use PPPoE over AAL5 logical link control (LLC) encapsulation. LLC encapsulation allows a single ATM virtual connection to transport multiple protocols.

In this example, you configure the physical interface at-2/0/0 for Ethernet over ATM encapsulation and then create a logical interface for PPPoE over LLC encapsulation.

You can use either J-Web or the CLI configuration editor to configure PPPoE on an ATM-over-ADSL or ATM-over-SHDSL interface.

This topic covers:

J-Web Configuration

To set the virtual path identifier (VPI) on an ATM-over-ADSL physical interface:

Select Configuration>View and Edit>Edit Configuration.
Next to Interfaces, click Configure or Edit.
In the Interface name box, click at-2/0/0.
Next to ATM options, click Configure.
Next to Vpi, click Add new entry.
In the Vpi number box, type 0.
Click OK twice.

To configure the ADSL operating mode on the ATM-over-ADSL physical interface:

Next to Dsl options, click Configure.
From the Operating mode list, select auto.
Click OK twice.

To configure PPPoE encapsulation on the ATM-over-ADSL physical interface:

From the Encapsulation list, select ethernet-over-atm.

To create an ATM-over-ADSL logical interface and configure LLC encapsulation:

Next to Unit, click Add new entry.
In the Interface unit number box, type 0.
From the Encapsulation list, select ppp-over-ether-over-atm-llc.
In the Multicast vci box, type 0.120.
Click OK twice.
