Enabling Ip Multicast - Huawei Quidway S7700 Configuration Manual - Multicast

Quidway S7700 Smart Routing Switch
Configuration Guide - Multicast
The host where the IGMP is run responds to the IGMP Query message of the S7700. If the host
gives no response and the operation times out, the S7700 considers that the multicast group does
not contain any member on the network segment and cancels data forwarding.
To enable hosts on the network segment of the interface to join the specified groups and receive
packets from the groups, you can set an ACL on the related interface to limit the range of groups
that the interface serves.
