Configuring PPP and PPPoE over ATM in AOS Quick Start Guide

This guide explains how to configure Point to Point Protocol (PPP) over Asynchronous Transfer Mode (ATM) in AdTran Operating System (AOS). You should use this guide only if your Service Provider requires PPP over ATM or PPPoE over ATM for interconnection.

Requirements

Your AOS device must already be configured with an ATM interface that is up without errors. Consult the guide titled “Configuring ATM in AOS” for instructions on configuring an ATM interface.

Software Requirements:

• AOS Version 10 or Higher

For Accessing the Web Interface

• Web Browser with Javascript  (Example: Internet Explorer or FireFox 1.5)

For Accessing the Command Line Interface

• VT100 Emulator (Example: HyperTerminal)

Hardware Requirements:

• AOS device with an ATM capable interface.

Information Requirements:

• PPP Mode (PPP or PPPoE)
• IP Address and Type (Dynamically Assigned or Static)
• Authentication Type (PAP, CHAP or None)

Configuring

PPP over ATM can be configured via both the Web Interface and the Command Line Interface. You should choose only one method, not both.

Configuring via the Web Interface

The following section explains how to use the Web Interface to configure the PPP over ATM. For more information about enabling and gaining access to the Web Interface, consult the guide titled “ Enabling the Web Interface in AOS”.

Accessing the ATM Sub-Interface:

1)      Click ‘Physical Interfaces’.

a.       In the NetVanta 300 Series Routers, click ‘Public Interface’, and skip to step 3.

2)      Click on the Physical Interface that transports ATM. (Example: ADSL 0/1)

3)      Click the ‘Configure ATM Settings’ button. If you do not see that button, you have not yet configured ATM for this interface. You should consult the guide titled “Configuring ATM in AOS” for more information.

a.       In the NetVanta 300 Series Routers, you will need to click ‘Advanced Configuration’, to see the ‘Configure ATM Settings Button.

4)      Click the ATM Sub-Interface that corresponds to the appropriate connection. (Example: ATM 1.1)

Configuring the ATM Sub-Interface:

5)      Set the ‘Interface Mode’ to the appropriate PPP type.

a.       If your provider requires PPPoE, choose ‘PPPoE’.

b.      If your provider requires PPP, choose ‘PPP’.

6)      Click ‘Apply’ to be taken to the PPP configuration page.

Configuring the PPP Interface:

7)      Check the ‘Enabled’ checkbox.

😎      Set the ‘Sent Authentication Type’ according to your service provider’s requirements. Only your service provider can tell you the correct setting.

a.       If your service provider does not require authentication, choose ‘None’.

b.      If your service provider requires CHAP authentication, choose ‘CHAP’.

c.       If your service provider requires PAP authentication, choose ‘PAP’.

9)      Set the ‘Sent Username’ and ‘Sent Password’ appropriately. Only your service provider can tell you the correct username and password if applicable.

10)  Set ‘Peer Authentication Type’ to ‘None’.

11)  Based on your Service Provider’s requirements set the ‘Address Type’. Only your service provider can tell you the correct setting.

a.       If your service provider will dynamically assign an address to your Public Interface, choose ‘Negotiated’. Check the ‘Default Route’ checkbox.

b.      If your service provider requires that you manually assign an address, choose ‘Static’, and enter the appropriate IP Address and Subnet Mask.

12)  Click ‘Apply’.

Note: The PPP Interface status and statistics can be viewed at the bottom of the PPP Interface configuration page. You should use this information to troubleshoot.

Configuring via the Command Line Interface

PPP over ATM can be configured via the Command Line Interface in AOS. For more information about gaining access to the Command Line Interface, consult the guide titled “Accessing the Command Line Interface in AOS”.

Accessing the PPP Interface:

1)      Type enable to enter ‘enabled mode’.

2)      Type configure terminal to access ‘global configuration mode’.

3)      Type interface ppp 1 to create a PPP Interface. You may need to choose a different number, if “ppp 1” already exists for a different connection.

Configuring the PPP Interface:

4)      Assign the PPP interface an IP Address according to your service provider’s requirements.

a.       If your service provider will dynamically assign an IP Address, type ip address negotiated.

b.      If your service provider requires that you manually assign an IP Address type ip address <ip address here>  <subnetmask here>.

(Example: ip address 1.2.3.4  255.255.255.0)

5)      Cross-connect the PPP interface with the appropriate ATM Sub-Interface. Consult the guide titled “Configuring ATM in AOS” for more information about creating ATM Sub-Interfaces.

a.       If your service provider requires PPPoE, type cross-connect  <cross-connect number>  atm <interface.sub-interface> ppp  <ppp number>  pppoe-client .

(Example: cross-connect 1  atm 1.1  ppp 1 pppoe-client)

b.      If your service provider requires only PPP, type cross-connect  <cross-connect number>  atm <interface.sub-interface> ppp  <ppp number>  (Example: cross-connect  1  atm 1.1  ppp 1)

6)      Type no shutdown to enable the PPP Interface.

Note: Use the show interface ppp <ppp number>  command to view the status and statistics of the PPP Interface. You should use this information to troubleshoot.
