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

Web-Based Switch Management 241

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:

Parameter Description

Interface Name

Displays the name of the IP interface

that is to be configured for IGMP.

This must be a previously configured

IP interface.

IP Address

corresponding to the IP interface

name above.

Version <2>

Enter the IGMP version (1 or 2) that

will be used to interpret IGMP

queries on the interface.

and 65535 seconds, with a default of
