Query Period
The IGMP protocol requests that a server periodically publish to users on the
LAN the multicast IP Addresses that it can service. The IGMP Query Period
defines the time interval (in seconds) between each of these queries for
membership.
Maximum Response Time
The IGMP Maximum Response Time defines the time interval (in seconds) that
the unit should wait before it assumes that no parties are interested in the
content published via an IGMP query. This option is expressed in seconds and
the maximum response time that is accepted by the unit is Query Period minus
two seconds.
Number of Missed Responses Before Leaving IGMP Group
The number entered in this dialog box defines the number of membership
queries that go unanswered from LAN clients before the Ethernet interface will
no longer forward data for that IGMP group.
