Configuring MLD Snooping Last Listener Query

Configure the Last Listener Query Interval and Last Listener Query Count when the switch
receives an MLD leave message. If specified count of Multicast-Address-Specific Queries
(MASQs) are sent and no report message is received, the switch will delete the multicast
address from the multicast forwarding table.
Follow these steps to configure Last Listener Query Interval and Last Listener Query
Count in the Global Config section:
1) Specify the interval between MASQs.

3) Click Apply.
Verifying MLD Snooping Status
MLD Snooping Status Table displays VLANs and ports with MLD Snooping enabled.
When the switch receives an MLD leave message, the switch obtains the address
of the multicast group that the host wants to leave from the message. Then the
switch sends out MASQs to this multicast group through the port receiving the
leave message. This parameter determines the interval between MASQs. The
valid values are from 1 to 5 seconds.
