• A collection of one or more N_Ports to which a multicast frame is to be delivered
• Unacknowledged service based on Class 3 (unreliable multicast) • Class 2 cannot be supported because one frame transmitted cannot have multiple ACK frames in response. The source port would be unable to understand why multiple ACKs are returned for a single frame. • Class 6 operation will provide a full implementation of multicast.
