Configure a PPPoE Interface

Table of Contents
Let us learn to configure a PPPoE interface in Prisma SD-WAN. Point-to-Point Protocol over Ethernet (PPPoE) is a configuration option for Digital Subscriber Line (DSL) circuits.

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 WorkflowsDevicesClaimed Devices, select the device you want to configure.
  2. On the device's interface configuration page, select the Interfaces+ Add Interface to add any interface.
  3. In the General section,
    1. Enter a Name and Optional Description, and add Tags for the port channel interface.
    2. For Admin Up, select Up.
  4. In the Network Setting section,
    1. For Interface Type, select Port.
    2. For Use This Port For, select Internet or Private WAN from the given list.
    3. For Attach PPPoE, select Yes and then Save Port.
      PPPoE is now attached to an interface. Proceed to configure PPPoE attributes.
    4. 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.
    5. 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.
    6. Select Enable IPv6 On This Interface to configure IPv6.
      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).
    7. Toggle Scope as Global or Local.
    8. Select IPFIX Collector and IPFIX Filter from the available list.
    9. Select the port (only ports 7, 8, 9, 10 are PoE capable and can be enabled) to enable PoE.
    10. Select Receive and transmit or Receive only for LLDP/LLDP-MED. By default, all non-PoE ports are set to receive-only mode and PoE ports are set to transmit-and-receive mode.
  5. In the Advanced Settings section, specify IoT SNMP Discovery Source Interface as Enable or Disable, IP MTU, and Physical from the available range.
    IP MTU value should be at least 1280 for IPv6. If it is less than 1280, IPv6 cannot be enabled.
