Igmp Snooping Configuration; Enabling Igmp Snooping - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
Caution:
An IGMP-Snooping-enabled S3900 series Ethernet switch judges whether the
multicast group exists when it receives an IGMP leave packet sent by a host in a
multicast group. If this multicast group does not exist, the switch will drop the IGMP
leave packet instead of forwarding it.
