Figure 6-29. IGMP Snooping Settings screen
To configure IGMP Snooping:
Toggle the Switch IGMP Snooping field to Enabled. Toggle the Querier State field to the appropriate
choice between Non-Querier, V1-Querier, and V2-Querier to determine the version of IGMP that is used
in your network. A value between 1 and 255 can be entered for the Robustness Variable (default is 2).
The Query Interval can be set between 1 and 65535 seconds (default is 125 seconds). This sets the
time between IGMP queries. The Max Response allows a setting between 1 and 25 seconds (default is
10) and specifies the maximum amount of time allowed before sending a response report.
Highlight APPLY and press Enter to make the settings effective.
The user-changeable parameters in the Switch are as follows:
• Switch IGMP Snooping:<Disabled> – This field can be toggled using the space bar between
Disabled and Enabled. This is used to enable or disable IGMP Snooping, globally, on the Switch.
• Action:<Add/Modify> – Toggle to the desired option, Add/Modify or Delete.
• VLAN ID:[1] – Enter the appropriate VLAN ID in this field.
• State:<Enabled> – Toggle this field to Enabled to activate this entry.
• Querier State:<Non-Querier> – This field can be toggled between Non-Querier, V1-Querier, and V2-
Querier. This is used to specify the IGMP version (1 or 2) that will be used by the IGMP interface
when making queries.
• Robustness Variable:[2 ] – A tuning variable to allow for sub-networks that are expected to lose a
large number of packets. A value between 1 and 255 can be entered, with larger values being
specified for sub-networks that are expected to lose larger numbers of packets.
• Query Interval:[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.
