5.11 IGMP Snooping

IGMP Snooping is used to implement dynamic registration of L2 multicast on

the switch. To accommodate L2 multicast with IGMP Snooping, IGMP must be

activated on the client device and router as the XMS-1024 only snoops the IGMP

messages transmitted by the client device and router to dynamically maintain

the L2 multicast group. Multicast registration on this switch does not affect the

settings of other switches in the environment. The switch transmits an IGMP query

message and receives the IGMP response from the client device. Based on the

receiving port, VLAN ID, and multicast of the IGMP packets, the XMS-1024 cre-

ates and maintains a multicast group. After creating a group, it forwards the IGMP

packets to other switches and routers in the network. Only the ports included in a

multicast group can receive the multicast data stream. This reduces network trafﬁ c

and saves network bandwidth.
