Defining Multicast Groups
The Multicast Group Page displays the ports and LAGs attached to the Multicast service group in the Ports and LAGs tables. The Port and LAG tables also reflect the manner in which the port or LAGs joined the Multicast group. Ports and LAGs can be added either to existing groups or to new Multicast service groups. The Multicast Group Page permits new Multicast service groups to be created. The Multicast Group Page also assigns ports to a specific Multicast service address group.
Bridge multicast groups are defined according to MAC addresses. In cases where the Bridge Multicast Address is an IP Address it is required to be mapped to a MAC address. Multiple IP address can be mapped to a single MAC address and are presented in the form of an IP Address range (see Edit Multicast Group Page). The MAC address for the multicast group is created as a result of mapping the last 23 bits of the IP Address to the Last 23 bits of the MAC address and this allows multiple IP addresses to be mapped to one MAC address. The first three octets of such a mapped MAC address have the standard form of 01:00:5E:XX:XX:XX.
