1.5.2 (Optional) Configuring an SSM Group Policy

Context
If a user joins an ASM multicast group, you need to configure an SSM group policy in the VLAN
to add the multicast group address to the range of SSM group addresses.
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 ssm-policy basic-acl-number
An SSM group policy is configured.
By default, the address of an SSM group ranges from 232.0.0.0 to 232.255.255.255. After you
configure an SSM policy, the multicast groups specified in the SSM policy are considered as
SSM groups.

1.5.3 (Optional) Configuring Layer 2 Multicast SSM Mapping

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.

Data
Source addresses mapped to the multicast group addresses
NOTE
When you create an ACL for an SSM policy, the configuration takes effect only if you select permit and
specify a multicast address in the rule command. The configuration does not take effect if deny is selected
or if the specified address is not a multicast address.
