how the Ethernet Interface is configured either to receive requests to join IGMP groups or
announce groups for others to join.
The IGMP Information page contains the following options/fields:

publish to users on the LAN the Multicast IP Addresses
that it can service. The IGMP query period defines the
time interval (in seconds) between each of these
queries for membership.

The IGMP max response time defines the time interval
(in seconds) that the
IP Module should wait before it
assumes that no parties are interested in the content
published via an IGMP query. This option is expressed
in seconds, and the max response time that is
accepted by the
IP Module is 25 seconds.
