Overview
IGMP Button
The IGMP button facilitates the management of the IGMP capabilities
associated to the multicast streams presented in the Overview stream
monitoring list. It provides specific controls (on a stream basis or for a
range) 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 enable and
disable 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 automatically 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.
Note: Stopping the test case will automatically issue a leave request to release all
streams in joining or joined state.
