DES-3326S Layer 3 Fast Ethernet Switch User’s Guide

This dialog box allows the configuration of IGMP for each IP interface configured on the switch. IGMP can be configured as Version 1 or 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 65,500 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 a lot of 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:
