MLD Snooping-proxy
VLAN ID Select the VLAN ID for which you want to configure a port’s MLD snooping-proxy settings.
Port This field displays 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.
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
Do wnstre a m
port or
Upstre a m
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 messages
when receiving queries from a multicast router.
Otherwise, select
No ne
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 (
Im m e dia te
) or wait for an MLD report before the
leave timeout (
No rm a l
) or fast leave timeout (
Fa st
) 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.
