3.9 IGMP Snooping
When the IGMP Snooping is enabled, the GS-5008PL will process IGMP control packets for multicast
traffic forwarding. The switch will record information of IGMP v2 packets and maintain database for
multicast traffic. Then multicast traffic will be forwarded according to the database.
When IGMP Snooping feature is enabled, switch will record information of IGMP v3 packets and maintain
database for multicast traffic. Then multicast traffic will be forwarded according to the database. In IGMP
v3, multiple multicast group and source IP information can be recorded in one IGMP v3 packet,
GS-5008PL will record each multicast group address and ignore source IP information.
When the IGMP Snooping feature is enabled and IGMP Static Router Port is set, only this port can be
used as a router port, other ports will be as member ports only. In this case, member ports receive query
packets will drop the query packets.
