D-Link xStack DES-3800 Series User Manual page 171

This window allows the configuration of IGMP for each IP interface configured on the Switch. IGMP
can be configured as Version 1, 2 by toggling the Version field using the pull-down menu. The length
of time between queries can be varied by entering a value between 1 and 31,744 seconds in the Query
Interval field. The maximum length of time between the receipt of a query and the sending of an
IGMP response report can be varied by entering a value in the Max Response Time field.
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.
The following fields can be set:
