Netgear M4100-D10-POE (FSM5210Pv1h1) - 8‐port FE + 2 GE Combo L2 Managed PoE Switch Guia Do Programa

Internet Group Management Protocol (IGMP) Layer 3 is widely used for IPv4 network 
multicasting. In Layer 2 networks, IGMP uses resources inefficiently. For example, a Layer 2 
switch sends multicast frames to all ports, even if there are receivers connected to only a few 
ports.

To address this problem, the IGMP Snooping protocol was developed. The problem still 
appears, though, when receivers are in different VLANs. 

Multicast VLAN registration (MVR) is intended to solve the problem of receivers in different 
VLANs. It uses a dedicated manually configured VLAN, called the multicast VLAN, to forward 
multicast traffic over a Layer 2 network with IGMP snooping.

This command enables MVR.

This command disables MVR.

This command adds an MVR membership group. <A.B.C.D> is the IP multicast group being 
added.

The count is the number of incremental multicast groups being added (the first multicast 
group is A.B.C.D). If a count is not specified, only one multicast group is added.
