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.
Last Listener
Query Interval
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.
2) Specify the number of MASQs to be sent.
