Huawei quidway s7700 - Checking the Configuration

Context
By configuring SSM mapping, you can set up one-to-one mappings between multicast groups
and multicast sources.
SSM mapping can be configured only when IGMP snooping is enabled globally and in the
corresponding VLAN and when the IGMP messages version is set to IGMPv3 in the VLAN.
If the multicast replication function is configured, you only need to configure SSM mapping in
the multicast VLAN.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
vlan vlan-id
The VLAN view is displayed.
Step 3 Run:
igmp-snooping version 3
The version number of IGMP is set to 3.
The default version number of IGMP snooping is 2, but IGMPv2 version does not support SSM
mapping.
Step 4 Run:
igmp-snooping ssm-mapping enable
SSM mapping is enabled in the VLAN.
By default, SSM mapping is disabled.
Step 5 Run:
igmp-snooping ssm-mapping ip-group-address { ip-group-mask | mask-length } ip-
source-address
The mapping between a multicast group address and a multicast source is configured.
The specified multicast group address must be in the range of multicast group addresses specified
by the SSM policy. For the configuration of the SSM policy, see 2.7.2 (Optional) Configuring
an SSM Group Policy.
