configured multicast MAC address. If matches, the switch CPU

modifies the hardware address table to include this receiver port and

VLAN as a forwarding destination of the MVLAN

‹ Leave Operation

Subscriber sends an IGMP leave message to the switch to leave the

multicast. The switch CPU sends an IGMP group-specific query

through the receiver port VLAN. If there is another subscriber in the

VLAN, subscriber must respond within the max response time. If

there is no subscriber, the switch eliminates this receiver port.

‹ Immediate Leave Operation

Subscriber sends an IGMP leave message to the switch to leave the

multicast. Subscribers do not need to wait the switch CPU to send an

IGMP group-specific query through the receiver port VLAN. The

switch will immediately eliminate this receiver port.

Scenario of MVR

In the following section, we will provide an example to illustrate how to

configure MVR. In this scenario, the main job of media server is to transmit the

media stream via port 10 to ES-4024A and the multicast traffic flowing into the

ES-4024A will be tagged with PVID=100. In the ES-3124, we enable the MVR

function to allocate the multicast traffic from ES-4024A to separate VLAN

hosts.
