ZyXEL Communications ES-4024A Scenario of MVR, ‹ Leave Operation, ‹ Immediate Leave Operation

ES-4024A Series Switch Support Notes

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.
