port will be processed: if the receiving port is a new member port, it will be added to the forward list of the multicast group with its member port aging time specified; if the receiving port is already a member port, its member port aging time will be directly reset. 3. Member Leave The host will send MLD Done message when leaving a multicast group to inform the router of its leaving. When Immediate Leave is not enabled in a VLAN and a Done message is received on a port of this VLAN, the switch will generate MASQs on this port to check if there are other members in this multicast group. The user can control when a port membership is removed for an exiting address in terms of the number and interval of MASQs. If there is no Report message received from this port during the switch maximum response time, the port on which the MASQ was sent is deleted from the multicast group. If the deleted port is the last member of the multicast group, the multicast group is also deleted. The switch will send Done message to the router ports of the VLAN. In IPv6,Layer 2 switches can use Multicast Listener Discovery (MLD) Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that IPv6 multicast data is selectively forwarded to a list of ports that want to receive the data. This list is constructed by snooping IPv6 multicast control packets. The MLD Snooping function can be implemented on Global Config, VLAN Config, Filter Config, Port Config, Static Multicast, Querier Config and Packet Statistics pages. 10.2.1 Global Config To configure the MLD Snooping on the switch, please firstly configure MLD global configuration and related parameters on this page. Chose the menu Multicast→MLD Snooping→Global Config to load the following page. Figure 10-14 Global Config The following entries are displayed on this screen:  Global Config MLD Snooping: Enable or disable MLD Snooping function globally. 161

3.
Member Leave
The host will send MLD Done message when leaving a multicast group to inform the router of its
leaving.
When Immediate Leave is not enabled in a VLAN and a Done message is received on a port of
this VLAN, the switch will generate MASQs on this port to check if there are other members in this
multicast group. The user can control when a port membership is removed for an exiting address
in terms of the number and interval of MASQs. If there is no Report message received from this
port during the switch maximum response time, the port on which the MASQ was sent is deleted
from the multicast group. If the deleted port is the last member of the multicast group, the multicast
group is also deleted. The switch will send Done message to the router ports of the VLAN.

Layer 2 switches can use Multicast Listener Discovery (MLD) Snooping to limit the
