IGMP Multicast Filtering
IGMP is used by IP-supporting network devices to register hosts with multicast groups. It can be used on all
LANs and VLANs that contain a multicast capable IP router, and on other network devices that support
multicast filtering. Moxa switches support IGMP version 1, 2 and 3. IGMP version 1 and 2 work as follows:
• The IP router (or querier) periodically sends query packets to all end-stations on the LANs or VLANs that are
connected to it. For networks with more than one IP router, the router with the lowest IP address is the
querier. A switch with IP address lower than the IP address of any other IGMP queriers connected to the LAN
or VLAN can become the IGMP querier.
• When an IP host receives a query packet, it sends a report packet back that identifies the multicast group
that the end-station would like to join.
• When the report packet arrives at a port on a switch with IGMP Snooping enabled, the switch knows that the
port should forward traffic for the multicast group, and then proceeds to forward the packet to the router.
• When the router receives the report packet, it registers that the LAN or VLAN requires traffic for the
multicast groups.
• When the router forwards traffic for the multicast group to the LAN or VLAN, the switches only forward the
traffic to ports that received a report packet.
IGMP version 3 supports “source filtering,” which allows the system to define how to treat packets from
specified source addresses. The system can either white-list or black-list specified sources.
IGMP version comparison
IGMP Version Main Features Reference
V1 Periodic query RFC-1112
V2 Compatible with V1 and adds:
a. Group-specific query
b. Leave group messages
c. Resends specific queries to verify leave message was the last one in
the group
d. Querier election
RFC-2236
V3 Compatible with V1, V2, and adds:
Source filtering
- accept multicast traffic from specified source
- accept multicast traffic from any source except the specified source
RFC-3376
GMRP (GARP Multicast Registration Protocol)
Moxa switches support IEEE 802.1D-1998 GMRP (GARP Multicast Registration Protocol), which is different from
IGMP (Internet Group Management Protocol). GMRP is a MAC-based multicast management protocol, whereas
IGMP is IP-based. GMRP provides a mechanism that allows bridges and end stations to register or de-register
Group membership information dynamically. GMRP functions similarly to GVRP, except that GMRP registers
multicast addresses on ports. When a port receives a GMRP-join message, it will register the multicast
address to its database if the multicast address is not registered, and all the multicast packets with that
multicast address are able to be forwarded from this port. When a port receives a GMRP-leave message, it will
de-register the multicast address from its database, and all the multicast packets with this multicast address
will not be able to be forwarded from this port.
Static Multicast MAC
Some devices may only support multicast packets, but not support either IGMP Snooping or GMRP. The Moxa
switch supports adding multicast groups manually to enable multicast filtering.
Enabling Multicast Filtering
Use the USB console or web interface to enable or disable IGMP Snooping and IGMP querying. If IGMP Snooping
is not enabled, then IP multicast traffic is always forwarded, flooding the network.
