IGMP snoop querier is used to keep host memberships alive. It's primarily used in a
network where there is a multicast streaming server, hosts subscribed to the server and
no IGMP querier present. An IGMP querier sends out periodic IGMP query packets.
Interested hosts reply with an IGMP report packet. IGMP snooping is only conducted on
wireless radios. IGMP multicast packets are flooded on wired ports. IGMP multicast
packet are not flooded on the wired port. IGMP membership is also learnt on it and only
if present, then it is forwarded on that port.
Define an IP address applied as the source address in the IGMP query packet. This
address is used as the default VLAN querier IP address.
Use the spinner control to set the IGMP version compatibility to either version 1, 2 or 3.
The default setting is 3.
Specify the maximum time (from 1 - 25 seconds) before sending a responding report.
When no reports are received from a radio, radio information is removed from the
snooping table. For IGMP reports from wired ports, reports are only forwarded to the
multicast router ports. The default setting is 10 seconds.
Specify an interval in either Seconds (60 - 300) or Minutes (1 - 5) used as a timeout
interval for other querier resources. The default setting is 1 minute.
