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 enable
The IGMP function is enabled.
Step 4 Run:
igmp version 3
The version number of IGMP is set to 3.
To ensure that hosts running any IGMP version on the network segment can obtain SSM services,
it is recommended to run IGMPv3 on the S9300 interface.
Step 5 Run:
igmp ssm-mapping enable
SSM mapping is enabled.
