Multicast Communication

This discovery mechanism uses the same multicast network that is used by the ldmd daemon to detect collisions when automatically assigning MAC addresses. To configure the multicast socket, you must supply the following information:

#define	MAC_MULTI_PORT		64535
#define	MAC_MULTI_GROUP		""

By default, only multicast packets can be sent on the subnet to which the machine is attached. You can change the behavior by setting the ldmd/hops SMF property for the ldmd daemon.
