MES53xx, MES33xx, MES23xx Ethernet Switch Series
109
To activate IGMP Snooping, you must enable the 'bridge multicast filtering' function (see
Section 'Multicast addressing rules').
Identification of ports to which multicast routers are connected is based on the following events:
–
IGMP requests are received through the port;
–
The port received Protocol Independent Multicast (PIM/PIMv2) protocol packets;
–
The port received multicast routing packets of Distance Vector Multicast Routing Protocol
(DVMRP) protocol;
–
The port received MRDISC protocol packets;
–
The port received Multicast Open Shortest Path First (MOSPF) protocol packets.
