Chapter 23 Multicast Table 77 Advanced Application > Multicast > IPv6 Multicast > MLD Snooping-proxy > VLAN LABEL Robustness Variable DESCRIPTION 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. Last Member Query Interval 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. 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. Downstream Query Interval Maximum Response Delay Add 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. Enter the amount of time (in miliseconds) between general query messages sent by the downstream port. Enter the maximum time (in miliseconds) that the Switch waits for a response to a general query message sent by the downstream port. Click this to create a new entry or to update an existing one. Cancel Clear Index VID Delete Delete Cancel 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. Click Cancel to reset the fields to your previous configuration. Click Clear to reset the fields to the factory defaults. 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. This field displays the ID number of the VLAN group. Check the entry(ies) that you want to remove in the Delete column. Click Delete to remove the entry selected in the Delete column permanently.

MLD Snooping-proxy VLAN Port Role Setting
Click the
Port Role Setting
link in the
Advanced Application
>
Multicast > IPv6 Multicast >
MLD Snooping-proxy > VLAN
screen to display the screen as shown.
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

navigation panel to save your changes to the non-volatile memory when you are
done configuring.

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
