NOTE: The robustness variable of the MLD snooping querier is used in creating the following
MLD message intervals:
Group Listener Interval – The amount of time that must pass before a multicast router
decides that there are no more listeners present of a group on a network. Calculated as
(robustness variable * query interval ) + (1 * query interval).
Querier Present Interval – The amount of time that must pass before a multicast router
decides that there are no other querier devices present. Calculated as (robustness variable *
query interval) + (0.5 * query response interval).
Last Listener Query Count – The amount of group-specific queries sent before the router
assumes there are no local listeners in this group. The default value is the value of the
robustness variable.

MLD Router Port Settings

The following window is used to designate a port or range of ports as being connected to multicast enabled routers. When IPv6
routing control packets, such as DVMRP, OSPF or RIP, or MLD Query packets are found in an Ethernet port or specified VLAN,
the Switch will set these ports as dynamic router ports. Once set, this will ensure that all packets with a multicast router as its
destination will arrive at the multicast-enabled router, regardless of protocol. If the Router's Aging Time expires and no routing
control packets or query packets are received by the port, that port will be removed from being a router port.
To view this window, click L2 Features > MLD Snooping > MLD Router Port Settings, as shown below.

seconds with a default setting of 1 second.
Configure the MLD version of the query packet which will be sent by the router.
Specifies the link node timeout, in seconds. After this timer expires, this node will no
longer be considered as listening node. Default setting is 260 seconds.
Specifies the maximum amount of time a router can remain in the Switch's routing
table as a listening node of a multicast group without the Switch receiving a node
listener report. Default setting is 260 seconds.
Specifies the maximum amount of time a router can remain in the Switch after
receiving a done message from the group without receiving a node listener report.
Default setting is 2 seconds.
Choose Enabled to enable transmitting MLD Snooping Query packets or Disabled to
disable. The default is Disabled.
This read-only field describes the current querier state of the Switch, whether
Querier, which will send out Multicast Listener Query Messages to links, or Non-
Querier, which will not send out Multicast Listener Query Messages.
Used to enable or disable MLD snooping for the specified VLAN. This field is
Disabled by default.
This parameter allows the user to enable the fast done function. Enabled, this
function will allow members of a multicast group to leave the group immediately
when a done message is received by the Switch.
Select Enabled or Disabled for data driven learning status.
Use the pull-down menu to enable or disable the aging out of the entry.
Specify the data driven group lifetime in seconds. This parameter is valid only when
Data Driven Learning Aged Out is Enabled.
