Igmp Interface Configuration - D-Link DGS-3312SR Release 3.5 Manual

IGMP Interface Configuration

The Internet Group Multicasting Protocol (IGMP) can be configured on the Switch on a per-IP interface basis. To view the
IGMP Interface Table, open the IP Multicast Routing Protocol folder under Configuration and click IGMP Interface
Settings. Each IP interface configured on the Switch is displayed in the below IGMP Interface Table dialog box. To
configure IGMP for a particular interface, click the corresponding hyperlink for that IP interface. This will open another
IGMP Interface Configuration window:
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
The following IGMP interface parameters may be configured per interface:

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 2 and 255 can be entered, with larger values being
specified for subnetworks that are expected to lose larger numbers of packets.
Specifies the maximum amount of time between group-specific query messages,
including those sent in response to leave group messages. A value between 1 and 25.
The default is 1 second.
This field can be toggled between Enabled and Disabled and enables or disables
IGMP for the IP interface. The default is Disabled.
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.
