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.
