The IGMP information page is activated from the Protocol Configuration page. 
The IGMP Information page allows a user to view the IGMP clients that are actively 
listening to content being provided by the IP Module. It also allows the user to determine 
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: 
 

IGMP 

Read only showing IGMP status (Enabled or Disabled). 

View IGMP Table 

This table reports the content that clients have 
subscribed to the 

IP M

odule using the IGMP protocol. 

This allows a user to determine which services are 
being used and the minimum time before a service will 
be terminated. 

CDM-IP as Server: 
IGMP query period 

The IGMP protocol requests that a server periodically 
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. 

CDM-IP as Server: 
IGMP max. response time 

The IGMP max response time defines the time interval 
(in seconds) that the 

IP M

odule 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 M

odule is 25 seconds.
