Step 3 Run:
igmp-snooping group-limit group-limit vlan {vlan-id [ to vlan-id ] } &<1-10>

2.3.7 (Optional) Configuring Multicast Policies

Context
A multicast group policy in a VLAN is used to add the hosts in the VLAN to the specified
multicast groups and limit the number of multicast groups that a host can join.
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 group-policy acl-number [ version number ]
A multicast group policy is configured for the VLAN. Interfaces in the VLAN can dynamically
join only the multicast group that matches the specified ACL rules.
By default, no multicast group policy is available in a VLAN. That is, hosts in a VLAN can join
any multicast group. If the IGMP version is not specified for a multicast policy, the S3700 applies
the policy to all IGMP messages regardless of their versions.

Context
A Layer 2 device forwards IGMP Report or Leave messages received from multicast group
members to its directly connected Layer 3 device. If the Layer 2 device has multiple attached

NOTE
When you create an ACL for a multicast group policy of a VLAN, the configuration takes effect only if
you select deny in the rule command. That is, a multicast group policy can only prohibit hosts in a VLAN
from accessing all or specified multicast groups.
NOTE
If an advanced ACL is referenced by the group-policy, the ACL applies to the multicast group regardless
of the protocol type specified in the ACL.
