Multicast Snooping. In multicast snooping mode, a vSphere Distributed Switch provides IGMP and MLD snooping according to RFC 4541. The switch dispatches multicast traffic more precisely by using IP addresses. This mode supports IGMPv1, IGMPv2, and IGMPv3 for IPv4 multicast group addresses, and MLDv1 and MLDv2 for IPv6 multicast group addresses.

Multicast Filtering Because of limitations in the original VMware vSwitch forwarding model and the construction of the multicast mechanism, multicast traffic passing through a vSwitch can be received by virtual machines which have not subscribed to the multicast group sending that traffic.

Use multicast snooping on a vSphere Distributed Switch to forward traffic in a precise manner according to Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD) membership information that virtual machines send to subscribe for multicast traffic.

Sep 11, 2017 · If I have an identically configured physical machine connected to a VLAN 60 configured port on a physical switch, once again multicast works fine. It just seems that the vSwitch doesn't do its IGMP snooping (or VMWare equivalent) properly and drops multicast packets instead of forwarding them to the VM when it's connected to the VLAN 60 port group.

I have fielded a number of questions on VMware’s multicast support and figure it is time I did a short blog on it. There is a good white paper on the topic on the VMware site called Multicast Performance on vSphere 5.0 that deals with performance changes that have been made to enhance multicast support in vSphere 5. The recurring question I get is how multicast is handled in vSphere.

Where do I enable Multicast Filtering (IGMP) in my vSwitch environment? ANSWER. This setting is configured in the vShpere (thin)Client on the Desktop. In the vSphere thin client, right-click the VLan on which you want to enable Multicast. Click the Advanced option, and then change the Multicast filtering mode to IGMPsnooping.

In addition to the default basic mode for filtering multicast traffic, vSphere Distributed Switch 6.0.0 and later releases support multicast snooping that forwards multicast traffic in a more precise way based on the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) messages from virtual machines.
