Chapter 15 Multicast Configuration The following table describes the labels in this screen. Table 102 Multicast Configuration > Multicast: Detail LABEL DESCRIPTION Start IP Address This field displays the starting multicast IP address for a range of multicast IP addresses to which you want this IGMP filter profile to allow access. End IP Address This field displays the ending multicast IP address for a range of IP addresses to which you want this IGMP filter profile to allow access.

MVR allows one single multicast VLAN to be shared among different subscriber VLANs on the network. While isolated in different subscriber VLANs, connected devices can subscribe to and unsubscribe from the multicast stream in the multicast VLAN. This improves bandwidth utilization with reduced multicast traffic in the subscriber VLANs and simplifies multicast group management. You must enable IGMP snooping to use MVR. However, MVR only responds to IGMP join and leave control messages from multicast groups that are configured under MVR. Join and leave reports from other multicast groups are managed by IGMP snooping. 15.4.1 Types of MVR Ports In MVR, a source port is a port on the switch that can send and receive multicast traffic in a multicast VLAN while a receiver port can only receive multicast traffic. Once configured, the switch maintains a forwarding table that matches the multicast stream to the associated multicast group. 15.4.2 MVR Modes You can set your switch to operate in either dynamic or compatible mode. In dynamic mode, the switch sends IGMP leave and join reports through the source port(s) to the other multicast devices (such as multicast routers or servers) in the multicast VLAN. This allows the multicast devices to update the multicast forwarding table to forward or not forward multicast traffic to the receiver ports. NetAtlas EPON Manager User's Guide 205
