The Primary PP Node in IP Application Node test case connects to Primary Pilot Pack SUT via PCEF, sends Pilot Packet information (such as at PDN session allocation) to emulate a flow and response to requests from the PCEF.
You can enable the Primary PP Node by selecting Pilot Packets on the Test Configuration tab.
With an Ethernet User Node, you can define:
The IP address and routing options... The IP Address will increment for each node.
The MAC Address to override the Hardware MAC address so the packets sent out of the interface will use the provisioned MAC address rather the Hardware MAC Address.
Custom port selection... and error injection with the Advanced... button.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
