CDM-570/570L Satellite Modem with Optional IP Module Revision 4
IP Module - CLI and Telnet Operation MN/CDM570L.IOM
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 Module 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 Module
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 Module 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 Module will respond to an IGMP
query by requesting to join a Multicast Group published
by the server that is defined in the
IP Module’s route
table.
If set to NO, the
IP Module will not respond to IGMP
queries from a server. In this type of configuration, the
IP Module 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.
