STEP 4
For VLAN ID, select the VLAN that is to support MLD snooping.
STEP 5
Enter the parameters:
•
MLD Fast Leave Mode—Select Enable to allow the switch to immediately
remove a port (or LAG) from its multicast forwarding table when it receives
an MLD leave message for that multicast group. When enabled, the switch
removes the port without first sending out MAC-based general queries to
the interface. Enable Fast Leave mode only on VLANs in which only one host
is connected to each port. This prevents the inadvertent dropping of the
other hosts that are connected to the same port and remain interested in
receiving multicast traffic directed to that group.

•
MLD Group Membership Interval—Specify the time in seconds that the
switch waits for an MLD membership report from a particular group on a
particular interface before deleting the interface from the multicast
forwarding database entry. Select Default to specify 260 seconds, or select
User Defined and enter a value in the range 2 to 3600 seconds.

•
MLD Max Response Time—Specify the time in seconds that the switch
waits for a reply after sending a query on an interface because it did not
receive a report for a particular group in that interface. This value must be
less than the MLD Group Membership Interval value. Select Default to
specify 10 seconds, or select User Defined and enter a value in the range 1
to 65 seconds.

•
MLD Mrouter Expiry Time—Specify the time in seconds that the switch
waits for a query to be received on an interface before the interface is
removed from the list of interfaces with an MLD multicast router attached. A
value of 0 indicates an infinite timeout; i.e., no expiration. Select Default to
specify 0 seconds, or select User Defined and enter a value in the range 0 to
3600 seconds.

STEP 6
Click Apply and then click Close.
The new VLAN entry appears in the MLD Snooping Table.
STEP 7
Ensure that an MLD Mrouter interface has been configured for this VLAN. See
