Consider a
set to 60 seconds and the number of missed
responses set to 3. If a client joins an IGMP group,
then the service to that group will not be discontinued
until no clients respond to a query from the
for a period of 60*3 = 180 seconds.
C The Recognize IGMP Queries parameters determines
IP M
if the odule should respond to periodic queries
from an IGMP server that publishes a request to join a
specified multicast group. This parameter can assume
one of (2) values:
1. YES
2. NO
If set to YES, the
query by requesting to join a Multicast Group published
by the server that is defined in the
table.
If set to NO, the

IP M
odule may be configured to unconditionally
request to join an IGMP group at an interval specified
by the "Unsolicited Report Interval" option in the
Transmitter IGMP Client Configuration Page.
