Last Listener Query Interval
(1-25 Sec)
Use this parameter to specify 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. Default: 1 second.
Node Timeout (1-16711450
sec)
This parameter is used to specify the amount of time that must pass before a link
node is considered to not be a listener. Default: 260 seconds.
Router Timeout (1-16711450
sec)
This parameter is used to specify the maximum amount of time a router will remain
the Switch’s listener for multicast groups, without receiving a node listener report.
Default: 260 seconds.
Done Timer (1-16711450 sec)
This parameter is used to specify the maximum amount of time a group will remain in
the Switch after receiving a ‘Done’ message from the group, without receiving a node
listener report. Default: 2 seconds.
Querier State
Choose Enabled from the drop-down menu to specify that the Switch should act as
an MLD Querier (sends MLD query packets). Choose Disabled from the drop-down
menu to specify that the Switch should act as a Non-Querier (does not send MLD
query packets).
Fast Done
Use the drop-down menu to specify if the MLD Snooping Fast Done function should
be Enabled or Disabled from the specified VLAN. If enabled, the membership is
immediately removed when the system receives an MLD ‘Done’ message.
Version
Use the drop-down menu to specify the version of MLD packets that will be sent by
the specified ports. If an MLD packet received by the interface has a version higher
then the specified version, the packet will be dropped.
State
Use the drop-down menu to specify if MLD Snooping should be Enabled or Disabled
from the specified VLAN.
Querier Router Behavior
Displays if the Switch has been configured to act as a MLD Querier or Non-Querier.

The following parameters can be viewed/modified in the bottom half of the window:
Parameter Description
Static Router Port
Tick the checkboxes below the corresponding port numbers to specify that the ports
are connected to multicast-enabled routers. This ensures that these ports will
forward all packets having the multicast-enabled router as the destination will
successfully reach the router, regardless of the protocol, e.t.c.
Forbidden Router Port
Tick the checkboxes below the corresponding port numbers to specify that the ports
are not being connected to multicast-enabled routers. This ensures that these ports
will not propagate outbound routing packets.
Dynamic Router Port
Tick the checkboxes below the corresponding port numbers to specify that the
Switch will automatically determine If the port is connected to a multicast-enabled
router or not.
After setting the previous parameters, click the Ap ply button in the bottom section of the window to allo w your changes to be
implemented.
