User Manual Industrial Hotspot
6.2.2 IGMP Settings
RLX2 radios support IGMP v1 and v2. The default operation of the RLX2 radios
is to have IGMP functionality enabled, although the user can disable IGMP
entirely. Additionally, the user can specify settings associated with IGMP filtering
and snooping. Unknown multicast addresses can be sent to all ports (flood) or to
none (filtered) by changing the IGMP Multicast Filtering option. The user can
specify whether the radio will generate IGMP queries, and configure the query
interval time.
By RFC specification, only one device on a network should generate IGMP
queries. As such, RLX2 radios will only send a query if another device has not
sent a query within its Query Interval setting, even if Query Generation is
enabled.
