Synopsis: { active, passive }
Default: passive
Specifies the IGMP mode:
• PASSIVE : The switch passively snoops IGMP traffic and never sends IGMP queries.
• ACTIVE : The switch generates IGMP queries, if no queries from a better candidate for
the querier are detected for a while.
Synopsis: A 32-bit signed integer between 10 and 3600
Default: 60
The time interval between IGMP queries generated by the switch. NOTE: This parameter
also affects the Group Membership Interval (i.e. the group subscriber aging time),
therefore, it takes effect even in PASSIVE mode.
Synopsis: { true, false }
Default: true
Whether or not multicast streams will always be forwarded to multicast routers.
Whether or not multicast streams will be flooded out of all Rapid Spanning Tree Protocol
(RSTP) non-edge ports upon detection of a topology change. Such flooding is desirable, if
multicast stream delivery must be guaranteed without interruption.
