Configure a PPPoE Interface

Let us learn to configure a PPPoE interface.
Point-to-Point Protocol over Ethernet (PPPoE) is a configuration option for Digital Subscriber Line (DSL) circuits. You can configure PPPoE only on WAN ports and physical interfaces. You cannot configure it on sub-interfaces or logical interfaces such as bypass pairs or an interface with Layer 3 configuration, such as DHCP or static IP addresses.
Upon completing PPPoE authentication, the system establishes a connection with the DSL provider. In the event of PPPoE connection failures or termination, this PPPoE logical interface displays as down.
A logical PPPoE interface acts as the underlay interface for all
Prisma SD-WAN
-related features, statistics, counters, and configuration.
  1. Select
    Workflows
    Devices
    Claimed Devices
    , select the device you want to configure.
  2. Select the
    Interfaces
    tab.
  3. Select a port.
  4. For
    Admin Up
    , select
    Yes
    .
  5. (Optional)
    Enter a
    Description
    .
  6. For
    Interface Type
    , select
    Port
    .
  7. For
    PPPOE Attached?
    , select
    Yes
    and then
    Save Port
    .
    PPPoE is now attached to an interface. Proceed to configure PPPoE attributes.
  8. For
    Use This Port For
    , select
    Internet
    or
    Private WAN
    from the given list.
  9. Select a
    Circuit Label
    .
    • To enable this port to forward direct traffic and establish secure fabric links as per the site network policy, select a Circuit Label from the provided list.
    • If no label is selected, the port continues to be active and available for communication with the
      Prisma SD-WAN
      controller and for reporting statistics, but all network policy traffic ignores this interface.
  10. For
    IPv4 Configuration
    , choose
    Negotiated
    or
    Static
    .
    • Negotiated indicates that the IP address is negotiated with the PPPoE server.
    • Static indicates that the IP address is statically configured. If the IP address is static, the system ignores any PPPoE server-provided IP address and use the static IP address instead.
  11. Select
    Enable IPv6 On This Interface
    to configure
    IPv6
    .
  12. For
    IPv6
    Configuration, select
    AutoConf
    or
    Static
    .
    In both the cases, PPPoE server provides the linklocal address.
    Autoconf indicates the Global IP address is derived using stateless address autoconfiguration (SLAAC).
    Static indicates the IP address is statically configured. Additionally specify the IPv6 Address/Mask, Default Gateway (IPv6), and DNS server(s)(IPv6).
  13. (Optional)
    Enter
    Username
    and
    Password
    .
  14. Proceed to
    Advanced Options
