6.7.4. Multicast
Multicast management for gateway devices
Multicast is a group-communication method in which data transmissions
are addressed simultaneously to more than one destination computer.
Multicast transmissions can be point-to-multipoint, or multipoint-to-
multipoint.
By default, if CCTV cameras and devices that operate in a similar fashion
are linked to a Fluidmesh transceiver unit operating in Mesh Point mode,
the unit forwards all multicast traffic generated by the cameras to the
closest Mesh End unit in the wireless network.
Note that the Cisco FM1000 Gateway operates in Mesh End mode only.
By default, Fluidmesh devices operating in Mesh End mode do not
forward multicast traffic to a wireless network. The only exceptions to this
rule are universal plug and play (UPnP) and Internet Group Management
Protocol (IGMP) traffic.
To redirect traffic flow from the Cisco FM1000 Gateway to a Mesh Point
unit, all multicast flow redirection information must be specified using the
Multicast settings.
To set multicast rules on the unit, do the following steps:
1.
Click the -multicast link under ADVANCED SETTINGS in the
left-hand settings menu.
• The MULTICAST dialog will be shown

Compile the needed multicast rule. Use the following syntax rules
to create the rule:
• A multicast rule consists of two parts: a multicast group
designator and a destination address.
