The fields that can be configured are described below:
Parameter
Static Router Port
Other Querier present interval - Amount of time that must pass before a multicast
router decides that there is no longer another multicast router that is the Querier.
Last listener query count - Number of group-specific queries sent before the router
assumes there are no local listeners of a group. The default number is the value of
the robustness variable.
By default, the robustness variable is set to 2. You might want to increase this
value if you expect a subnet to be loosely.
The maximum amount of time between group-specific query messages, including
those sent in response to done-group messages. You might lower this interval to
reduce the amount of time it takes a router to detect the loss of the last listener of a
group.
Enter the data driven group expiry time value.
This allows the switch to be specified as an MLD Querier (sends MLD query
packets) or a Non-Querier (does not send MLD query packets). Set to enable or
disable.
Use the drop-down menu to enable or disable the fast done feature.
Used to enable or disable MLD snooping for the specified VLAN. This field is
Disabled by default.
Use the drop-down menu to enable or disable the report suppression features.
Enable or disable data driven learning of MLD snooping groups.
Enable or disable the age out function for data driven entries.
Specify the version of MLD packet that will be sent by this port. If a MLD packet
received by the interface has a version higher than the specified version, this
packet will be dropped.

Description
This section is used to designate a range of ports as being connected to multicast-
enabled routers. This will ensure that all packets with such a router as its destination
will reach the multicast-enabled router regardless of the protocol.
