P4RT-3.21: Google Discovery Protocol: PacketOut with LAG

Summary

Verify that GDP packets can be sent by the controller.

Testbed Type

• https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed

Procedure

• Configure two lag bundles between ATE and DUT with one member port in each of the LAG. A[ATE:LAG1] <---> B[LAG1:DUT]; C[ATE:LAG2] <---> D[LAG2:DUT];
• Enable the P4RT server on the device.
• Connect two P4RT clients in a master/secondary configuration.
• Configure the forwarding pipeline and install the P4RT table entry required for GDP.
• Send a GDP packet from the master with egress_singleton_port set to one of the connected interfaces.
• Verify that the GDP packet is received on the ATE port connected to the indicated interface.
• Repeat sending the packet in the same way but from the secondary connection.
• Verify that the packet is not received on the ATE.
