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 2 and 255 can be entered for the Robustness Variable (default is 2).
The Query Interval can be set between 1 and 65500 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 following fields can be set:
Parameter Description

Robustness
Variable:[ 2] A tuning variable to allow for sub-networks 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 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
