Configuring IGMP Snooping
When you select IGMP Snooping from the Configuration menu, the following screen is
displayed.
Internet Group Management Protocol (IGMP) Snooping allows the GbE Interconnect Switch
to recognize IGMP queries and reports sent between network stations or devices and an
IGMP host. When enabled for IGMP Snooping, the GbE Interconnect Switch can open or
close a port to a specific device based on IGMP messages passing through the GbE
Interconnect Switch.
You can change the following parameters:
• VLAN ID—Select a VID number in this field.
• State—Choose to enable or disable the IGMP settings.
• Querier State—Select the IGMP version that will be used by the IGMP interface when
making queries. Select from Non-Querier, V1-Querier, and V2-Querier.
• Robustness Variable—This is a tuning variable that allows you to configure the
acceptable number of packets that may be lost. Type a value between 1 and 255, with
larger values being specified for subnets that are expected to lose larger numbers of
packets.
• Query Interval—Type a value between 1 and 65,500 seconds to specify the length of
time between sending IGMP queries. The default is 125 seconds.
• Max Response—Type the maximum amount of time allowed before sending an IGMP
response report. The range is 1 to 25 seconds.
To set up IGMP Snooping:
1. Type a VID number in the VLAN ID field.
2. Select Enabled in the State field.
3. Select the desired setting in the Querier State field.
4. Type a value between 1 and 255 in the Robustness Variable field. The default is 2.
