20. Multicast Processing: This sets how multicast traffic is handled.
Multicast traffic can be received by a number of subscribing stations at
the same time, thus saving a great deal of bandwidth. In some of the
options below, the Array uses IGMP snooping to determine the stations
that are subscribed to the multicast traffic. IGMP (Internet Group
Management Protocol) is used to establish and manage the membership
of multicast groups.
Multicast handling options are only applicable to traffic transmitted from
the Array to wireless stations. Select one of the following options:
• Send multicasts unmodified. This is useful when multicast is not
needed because no video or audio streaming is required or when it is
used only for discovering services in the network. Some situations
where you might use this option are:
• for compatibility with ordinary operation, i.e., there is no
optimization or modification of multicast traffic.
