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

IGMP Interface Configuration

Figure 6-57. IGMP Interface Configuration screen

This menu 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 Ver field. The length of time between queries can be varied by entering a value between 1 and 65,535 seconds in the Query 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 field.

The Robustness Var 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.

 

Parameter

Description

 

 

 

 

Interface Name:[

]

Allows the entry of the name of the IP interface that is to

 

 

 

be configured for IGMP. This must be a previously

 

 

 

configured IP interface.

 

 

 

Ver:<2>

 

Can be toggled between 1 and 2. This determines the

 

 

 

IGMP version (1 or 2) that will be used to interpret IGMP

 

 

 

queries on the interface.

 

 

 

Robustness Var:[ 2]

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 subnets that are expected to lose

 

 

 

larger numbers of packets.

 

 

 

Query:[125 ]

 

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.

 

 

 

 

Max Response:[10]

 

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.

 

 

 

 

 

IP Address:

 

Displays the IP address corresponding to the IP interface

 

 

 

name entered above
