P4RT-7.1: LLDP: PacketIn

Summary

Verify that LLDP packets are punted with correct metadata.

Procedure

  • Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2.
  • Disable on-box processing of LLDP.
  • Enable the P4RT server on the device.
  • Connect a P4RT client and configure the forwarding pipeline. Install the P4RT table entry required for LLDP.
  • Send an LLDP packet from the ATE and verify that it is received by the client.
  • Verify that the packet has the ingress_singleton_port metadata set and it corresponds to the interface ID of the port that the packet was received on.
