The IGMP functions associated to all streams currently support Version 2 of
the IGMP standard (RFC 2236). The IGMP page provides the ability to
control and configure the IGMP capabilities associated to one specific
stream defined by a multicast IP address. It provides specific controls that
are adapted to the test case running status: stopped or started. When the
test case is stopped the management controls are displayed as Enable
Auto-Join and Disable Auto-Join that respectively enables and disables
the ability to join or not a multicast group when a test case is started. When
the test case is started, these controls are respectively modified to Join and
Leave to immediately join or leave a multicast group upon selection. Note
that while the test case is running, selecting the join button also configures
the IGMP Auto-Join to an enabled state. The same holds true when the
Leave button is selected i.e. following the leave request (if sent in
accordance to RFC 2236 rules) the IGMP Auto-Join is disabled. This page
also presents an IGMP statistic summary of all the multicast groups being
monitored by the FTB-8510B and provides a selection allowing a view of
the applicable statistics for a single stream. This page is further used to
configure the Join Timeout value to determine the success or failure of a
join request.
Note: Stopping the test case will automatically issue a leave request to release all
streams in joining or joined state.
