The goal of this test is to validate that the driver properly configures the MAC filter to allow the multicast packets to be passed by the µC/TCP-IP module when the target is registered to a multicast group. Also, the test ensures that, when the target is unregistered from the multicast group, multicast packets are dropped by the MAC filter. Anchor
The following steps are performed by NDIT to validate the behavior of the driver: Anchor
- Register the target to an IP multicast group.
...
- Have the test station send a packet to the IP multicast group.
...
- Upon reception of the multicast packet, the target replies to the test station to acknowledge the reception of the multicast packet.
...
- Unregister the target from the IP multicast group.
...
- Have the test station to send a packet to the IP multicast group.
...
- Verify that, after a certain timeout, no reply was received by the test station.
