5.1.4 Multicast

Figure 26 Multicast Configuration Page

• IGMP Snooping: Enable or Disable IGMP Snooping for Multicast traffic

• Mesh: This option controls default behavior for local and mesh multicast traffic that has no IGMP

snooping entries. If set to ‘Block’, all unregistered multicast traffic will be block. If set to ‘Send to

All’, all unregistered multicast traffic will be sent to all radios.

• Custom Pruning/Augmenting: Enable or Disable the Multicast group. The format for the field is

Multicast_ip_address, receiver_id1, … receiver_idn If IGMP snooping is disabled, multicast traffic

will only be forwarded to the radios in this list. If enabled, multicast traffic will only be forwarded

to radios in this list that have client devices requesting this traffic. Traffic may be forced to go to

a radio by adding the node with postfix “+”. Traffic may be prevented from reaching a radio by

adding postfix “-”. (e.g. 224.50.50.50 1234, 1235-, 1236+) If receiver_id is -1, it will stop multicast

traffic for this group.

Multicast Pruning Examples:

Data for multicast group 224.50.50.51 will be received only by radios with node-ids 1131 and

1261:

224.50.50.51, 1131, 1261

Data for multicast group 224.50.50.51 will be discarded at the transmitter and not put on the air:

224.50.50.51, -1
