Checking The Configuration - Huawei Quidway S9300 Configuration Manual - Multicast

Quidway S9300 Terabit Routing Switch
Configuration Guide - Multicast
Context
After receiving a Leave message from a host, the querier reports the message to the upstream
router instead of sending a Last Member Query message. This process is called IGMP prompt
leave. In this manner, the delay in response is reduced and the bandwidth occupied by various
messages is saved.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
The S9300 communicates with hosts through this interface. On the S9300, VLANIF interfaces
and loopback interfaces support IGMP.
Step 3 Run:
igmp prompt-leave [ group-policy basic-acl-number ]
The S9300 leaves the group immediately without sending the Last Member Query message.
By default, the S9300 sends the Last Member Query message after receiving a Leave message
from a host.

multicast group.
Run the display igmp interface [ interface-type interface-number ] [ verbose ] command
to check the configuration and running status of IGMP on the interface.
Run the display igmp routing-table [ group-address [ mask { group-mask | group-mask-
length } ] | source-address [ mask { source-mask | source-mask-length } ] ]
