MLD Global Settings:
MLD Snooping: Enable or disable the MLD Snooping.
Host Timeout (130-153025 sec): Specifies the time interval in seconds after which a port is removed from a
Multicast Group. Ports are removed if a Multicast group MLD report was not received from a Multicast port
within the defined Host Timeout period. The possible field range is 130 - 153025 seconds. The default
timeout is 260 seconds.
Router Timeout (60-600): Specifies the time interval in seconds the Multicast router waits to receive a
message before it times out. The possible field range is 60 - 600 seconds. The default timeout is 125
seconds.
Robustness Variable (2-255): The Robustness Variable allows adjustment for the expected packet loss
on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. The
Robustness Variable can not be set zero, and SHOULD NOT be one. Default is 2 seconds.
Last Member Query Interval (1-25 sec): The Last Member Query Interval is the Max Response Time
inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of
time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of
network. A reduced value results in reduced time to detect the loss of the last member of a group. The
default value is 1 second.
Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting
the Query Interval, the number of MLD messages can increase or decrease; larger values cause MLD
Queries to be sent less often. Default is 125 seconds.
Max Response Time (10-25 sec): Specifies the time interval in seconds after which a port is removed from
the Multicast membership group. Ports are removed from the Multicast membership when the port sends a
Done Message, indicating the port requests to leave the Multicast group. The field range is 10-25 seconds.
The default timeout is 10 seconds.
