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

To configure PPPoE encapsulation on an ATM-over-ADSL or ATM-over-SHDSL interface:

  1. Navigate to the top of the configuration hierarchy in either the J-Web or CLI configuration editor.
  2. Perform the configuration tasks described in Table 51.
  3. If you are finished configuring the router, commit the configuration.
  4. Go on to one of the following procedures:

Table 51: Configuring PPPoE Encapsulation on an ATM-over-ADSL or ATM-over-SHDSL Interface

Task

J-Web Configuration Editor

CLI Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy.

  1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
  2. Next to Interfaces, click Configure or Edit.

From the [edit] hierarchy level, enter

edit interfaces

Navigate to the ATM-over-ADSL or ATM-over-SHDSL interface—for example, at-2/0/0—and set the ATM virtual path identifier (VPI) to 0.

  1. In the Interface name box, click at-2/0/0.
  2. Next to ATM options, click Configure.
  3. Next to Vpi, click Add new entry.
  4. In the Vpi number box, type 0.
  5. Click OK twice.

Enter

set at-2/0/0 atm-options vpi 0

Do one of the following:

  • Configure the ADSL operating mode on the physical ATM interface—for example, autonegotiation.
  • Configure the SHDSL options:
    • Annex type—for example, Annex A.
    • SHDSL line rate for SHDSL interface—for example, automatic selection of line rate.
    • Loopback option for testing the SHDSL connection integrity on the physical ATM interface—for example, local.

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

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

Enter

set at-2/0/0 dsl-options operating-mode auto

To configure the SHDSL options:

  1. Next to Shdsl options, click Configure.
  2. From the Annex list, select Annex-a.
  3. From the Line Rate list, select auto.
  4. From the Loopback list, select local.
  5. Click OK until you return to the Interfaces page.

Enter

set at-2/0/0 shdsl-options annex annex-a line-rate auto loopback local

Configure Ethernet over ATM encapsulation on the physical ATM-over-ADSL or ATM-over-SHDSL interface.

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

Enter

set at-2/0/0 encapsulation ethernet-over-atm

Create an ATM-over-ADSL or ATM-over-SHDSL logical interface, configure LLC encapsulation, and specify a VCI number.

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

Enter

set at-2/0/0 unit 0 encapsulation ppp-over-ether-over-atm-llc vci 0.120
