Click the Port Role Setting link in the Advanced Application > Multicast > IPv6 Multicast >
MLD Snooping-proxy > VLAN screen to display the screen as shown. See
for more information on multicasting.
Robustness
Variable
Enter the number of queries. A multicast address entry (learned only on an upstream port
by snooping) is removed from the forwarding table when there is no response to the
configured number of queries sent by the router connected to the upstream port. This
value should be exactly the same as what’s configured in the connected multicast router.
This value is used to calculate the amount of time an MLD snooping membership entry
(learned only on the upstream port) can remain in the forwarding table.
Last Member
Query Interval
Enter the amount of time (in miliseconds) between the MLD group-specific queries sent
by an upstream port when an MLD Done message is received. This value should be
exactly the same as what’s configured in the connected multicast router.
This value is used to calculate the amount of time an MLD snooping membership entry
(learned only on the upstream port) can remain in the forwarding table after a Done
message is received.
When an MLD Done message is received, the Switch sets the entry’s lifetime to be the
product of Last Member Query Interval and Robustness Variable.
Downstream
Query Interval
Enter the amount of time (in miliseconds) between general query messages sent by the
downstream port.
Maximum
Response Delay
Enter the maximum time (in miliseconds) that the Switch waits for a response to a
general query message sent by the downstream port.
Add
Click this to create a new entry or to update an existing one.
This saves your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel
to save your changes to the non-volatile memory when you are done configuring.
Cancel
Click Cancel to reset the fields to your previous configuration.
Clear
Click Clear to reset the fields to the factory defaults.
Index
This is the index number of the MLD snooping-proxy VLAN entry in the table. Click on an
index number to view more details or change the settings.
VID
This field displays the ID number of the VLAN group.
Delete
Check the entry(ies) that you want to remove in the Delete column, then click the
Delete button.
Cancel
Click Cancel to clear the Delete check boxes.
