UDP Multicast
A multicast is a packet sent by one host to multiple hosts. In multicast, each host that belongs to a specific
multicast group will receive multicast packets for that group. To configure a host as a multicast receiver over
the Internet, it must inform the routers on its LAN. The Internet Group Management Protocol (IGMP) is used to
communicate group membership information between hosts and routers on a LAN. NPort IA5000A supports
IGMP version 2.
You could key in the IP (ex. 239.1.1.1) that multicast group assigned into the column of Destination IP address,
and next, NPort would automatically add the Group, receiving all packets from this group in order to fulfill the
function of multicast.
