IGMP Interface Configuration

Configure IGMP settings for each IP interface and click on the Apply button to apply the new or changed settings. The
new values will appear in the IGMP Interface Table. To view the table click Show All IGMP Interface Entries.
The following IGMP interface parameters may be configured per interface:
Parameter
Interface Name <System>
IP Address
Version <2>
Query Interval(1-65535)
<125>
Max Response Time(1-25)
<10>
Robustness Variable(1-255)
<2>

Description
Displays the name of the IP interface that is to be configured for IGMP. This
must be a previously configured IP interface.
Displays the IP address corresponding to the IP interface name above.
Enter the IGMP version (1 or 2) that will be used to interpret IGMP queries on
the interface.
Allows the entry of a value between 1 and 65535 seconds, with a default of
125 seconds. This specifies the length of time between sending IGMP
queries.
Sets the maximum amount of time allowed before sending an IGMP response
report. A value between 1 and 25 seconds can be entered, with a default of
10 seconds.
A tuning variable to allow for subnetworks that are expected to lose a large
number of packets. A value between 1 and 255 can be entered, with larger
values being specified for subnetworks that are expected to lose larger
numbers of packets.
NOTE: The Robustness Variable field allows IGMP to be 'tuned' for sub-
networks that are expected to lose many packets. A high value (max. 255)
for the robustness variable will help compensate for 'lossy' sub-networks.
A low value (min. 2) should be used for less 'lossy' sub-networks.
