Multicast Addresses
A multicast is a special form of broadcast where copies of a packet are
delivered to a specific group of end stations. This differs from a
broadcast, which is a transmission that sends copies of a packet to all
end stations on the network.
A multicast address is a destination address. Configuring a multicast
address allows you to restrict certain packets to a specific group of ports.
For example, you might use this feature to restrict the number of end
stations that are to receive packets from a server running special
applications.
Note
You can configure ten multicast addresses per switch.
Configuring a

specific users.
2. From the Omega Main Menu, select MAC Address Table.
