LABEL DESCRIPTION
MLD Snooping-
proxy VLAN ID
Select the VLAN ID for which you want to configure a port’s MLD snooping-proxy settings.
Slot (Stacking
mode)
This field appears only in stacking mode. Click the drop-down list to choose the slot
number of the Switch in a stack.
Port (Standalone
or stacking mode)
This field displays the port number. In stacking mode, the first box field is the slot ID and
the second field is the port number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row
first to set the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Port Role A port on the Switch can be either a Dow nstream port or Upstream port in MLD. A
downstream port connects to MLD hosts and acts as a multicast router to send MLD
queries and listen to the MLD host’s Report and Done messages. An upstream port
connects to a multicast router and works as a host to send Report or Done m essages
when receiving queries from a multicast router.
Otherwise, select None if the port is not joining a multicast group or does not belong to
this VLAN.
Leave Mode Select the leave mode for the specified downstream port(s) in this VLAN.
This specifies whether the Switch removes an MLD snooping membership entry (learned
on a downstream port) immediately (I m mediate) or wait for an MLD report before the
leave timeout (Normal) or fast leave timeout (Fast) when an MLD leave message is
received on this port from a host.
Leave Timeout Enter the MLD snooping normal leave timeout (in milliseconds) the Switch uses to update
the forwarding table for the specified downstream port(s).
This defines how many seconds the Switch waits for an MLD report before removing an
MLD snooping membership entry (learned on a downstream port) when an MLD Done
message is received on this port from a host.
Fast Leave
Timeout
Enter the fast leave timeout (in milliseconds) for the specified downstream port(s).
This defines how many seconds the Switch waits for an MLD report before removing an
MLD snooping membership entry (learned on a downstream port) when an MLD Done
message is received on this port from a host.
Apply Click Apply to save 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.
