7. From the Admin Mode menu, select Enable.
8. From the Fast Leave Admin Mode menu, select to enable or disable the MLD snooping
Fast Leave mode.
Enabling Fast Leave mode lets the switch immediately remove the Layer 2 LAN
interfaces from its forwarding table entry upon receiving an MLD Done message for that
multicast group without first sending MAC-based general queries to the interface.
We recommend that you enable Fast Leave admin mode only on VLANs for which only
one host is connected to a Layer 2 LAN port. This mode prevents the inadvertent
dropping of the other hosts that are connected to the same Layer 2 LAN port but are
configured to receive multicast traffic. Also, fast leave processing is supported only with
MLD version 1 hosts.
9. In the Group Membership Interval field, set the value for the group membership interval of
MLD snooping.
The valid range is 4 to 3620 seconds. The default value is 260 seconds.
10. In the Maximum Response Time field, set the value for the maximum response time of
MLD snooping.
The valid range is 1 to 20 seconds. The default value is 20 seconds. This value must be
shorter than the group membership interval value.
11. Click the Add button.
MLD snooping is enabled on the specified VLAN.
The Multicast Router Expiry Time field is a calculated field, displaying the value for the
multicast router expiration time of MLD snooping for the specified VLAN ID. This value is
calculated as the value in the Group Membership Interval field minus the value in the
Maximum Response Time field.
