[ScreenOS] Configuring a PPPoE Instance



Article ID: KB4236 KB Last Updated: 12 Jul 2013Version: 6.0
This article describes how to
  • configure a specific instance of Point-to-Point Protocol over Ethernet (PPPoE).
  • with a username and password and other parameters
  • bind the instance to an interface.

Directions are given for configuration through WebUI or CLI.


Configure a PPPoE instance


Configuration Using WebUI 

To configure a PPPoE Instance, perform the following steps:

Step one:Open the WebUI.

Step two: From the ScreenOS options menu, click Network, select PPP and then click PPPoE Profile.

Step three To configure a PPPoE Instance, enter the following information:
  • PPPoE Instance: Enter the name of the instance. Choose a descriptive name to help you identify the instance.
  • Enable: Select the checkbox to enable the PPPoE instance.
  • Bound to Interface: Select the interface to which you want to bind the PPPoE instance.
  • Username: Enter the user name for the PPPoE connection.
  • Password: Enter the password for the PPPoE connection.
  • Authentication: Select the authentication method.
    • Any means both CHAP and PAP authentication are used.
    • CHAP means only CHAP authentication is used.
    • PAP means only PAP authentication is used.
  • Access Concentrator: Specifies the AC to be used for the PPPoE connection.
  • Service: Specifies the service for the PPPoE connection.
  • Default Route Metric: Specifies the default route metric (cost) for PPPoE sessions.
  • Netmask: Specifies a subnet mask for the protected network.
  • Auto-Connect: Specifies the number of seconds before a previously-closed connection is automatically reinitiated. Specify a value between 0-10000. A value of 0 disables this function.
  • Idle Disconnect: Specifies the number of minutes that the connection is idle before the NetScreen device terminates the connection. A value of 0 disables this function and the connection is never terminated.
  • Clear IP on Disconnect: Removes IP information on connection termination.
  • Static IP: Specifies that the connection uses the IP address assigned to the device's interface.
  • Automatic Update of DHCP Servers DNS Parameters: When you initiate a PPPoE connection, your ISP automatically provides the IP addresses for the Untrust zone interface and the IP addresses for the Domain Name Service (DNS) servers. Enable this option if you want the NetScreen device to overwrite the local settings with the DNS settings it receives via PPPoE.
  • PPP Parameters:
    PPP lcp Echo Retries: Specifies the number of unacknowledged LCP Echo requests that occur before the connection is terminated. Specify a value between 1-30.
    PPP lcp Echo Timeout:
    Specifies the number of seconds between LCP echo request transmissions. Specify a value between 1-1000.

Step four: Click OK

Configuration Using CLI 

Use the following commands from the Command Line Interface to configure a PPPoE instance:

set pppoe name "test" username "test" password "juniper"
set pppoe name "test" enable
set pppoe name "test" interface "ethernet0/0"
set pppoe name "test" authentication any
unset pppoe name "test" authentication pap
set pppoe name "test" ac "AC"
set pppoe name "test" service "all"
set pppoe name "test" auto-connect 0
set pppoe name "test" idle-interval 30
set pppoe name "test" ppp lcp-echo-retries 10
set pppoe name "test" ppp lcp-echo-timeout 180
unset pppoe name "test" static-ip
unset pppoe name "test" clear-on-disconnect
set pppoe name "test" update-dhcpserver
set pppoe name "test" default-route-metric 1
set pppoe name "test" netmask
set pppoe name "test" ppp ipcp ipv6cp
