Multicast Filtering
RS400 201 ROS™ v3.5
Mode
Synopsis: { Passive, Active }
Default: Passive
Specifies 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 being the
querier are detected for a while.
Query Interval
Synopsis: 10 to 3600
Default: 60 s
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.
Router Ports
Synopsis: Any combination of numbers valid for this parameter
Default: None
This parameter specifies ports that connect to multicast routers. If you do not configure known
router ports, the switch may be able to detect them, however it is advisable to pre-configure
them.
Router Forwarding
Synopsis: { Off, On }
Default: On
This parameter specifies whether multicast streams will be always forwarded to multicast
routers.
RSTP Flooding
Synopsis: { Off, On }
Default: Off
This parameter specifies whether multicast streams will be flooded out of all RSTP non-edge
ports upon topology change detection. Such flooding is desirable, if guaranteed multicast
stream delivery after topology change is most important.
