Menu Options/Fields Entry Description
CDM-IP as Server:
Number of missed
responses before leaving
IGMP group M Defines the number of membership queries that go
unanswered from LAN clients before the Ethernet
Interface will no longer forward data for that IGMP
group.
Consider a IP M odule that has the IGMP query period
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
IP M odule
for a period of 60*3 = 180 seconds.
CDM-IP as Client:
Recognized IGMP queries C The Recognize IGMP Queries parameters determines
if the
IP M 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 IP M odule will respond to an IGMP
query by requesting to join a Multicast Group published
by the server that is defined in the
IP M odule’s route
table.
If set to NO, the IP M odule will not respond to IGMP
queries from a server. In this type of configuration, 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.
