Igmp-Snooping General-Query Source-Ip - Huawei Quidway S3900 series Command Manual

Command Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
Use the undo igmp-snooping fast-leave command to cancel the configuration.
By default, IGMP fast leave processing is disabled.
Normally, when receiving an IGMP Leave message, IGMP Snooping does not
immediately remove the port from the multicast group, but sends a group-specific query
message. If no response is received in a given period, it then removes the port from the
multicast group.
If this command is executed, when receiving an IGMP Leave packet, IGMP Snooping
removes the port from the multicast group directly. When the port has only one user,
enabling IGMP fast leave processing can save bandwidth.
Note:
This feature is effective for IGMP-V2-enabled clients.
When this feature is enabled, if one of the multiple users on a port leaves, the
multicast services for the other users in the same multicast group may be
interrupted.
Example
# Enable IGMP fast leave processing on Ethernet1/0/1 port.
