572 Managing Router Ports
Parameter Description
• ACTIVE : The switch generates IGMP queries, if no queries from a better candidate
for the querier are detected for a while.
IGMP Query Interval (s) 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.
Router Forwarding Default: true
Whether or not multicast streams will always be forwarded to multicast routers.
RSTP Flooding 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.
4. Assign one or more ports for IGMP to use when sending Membership Reports. For more information, refer to
Section 5.25.4.2, “Adding a Router Port”.
5. Click Commit to save the changes or click Revert All to abort. A confirmation dialog box appears. Click OK
to proceed.
6. Click Exit Transaction or continue making changes.
