A10E/A28E/A28F Configuration Guide
Configure IGMP Profile filtering rules to control the interface. One IGMP Profile can be set
one or more multicast group access control restrictions and access the multicast group
according to the restriction rules (permit and deny). If a rejected IGMP Profile filter profile is
applied to the interface, the interface will discard the IGMP report packet from this group
directly once receiving it and does not allow receiving this group of multicast data.
IGMP filtering rules can be configured on interface or VLAN.
IGMP Profile only applies to dynamic multicast groups, but not static ones.
Limit to the maximum number of multicast group
The maximum allowed adding number of multicast group and the maximum group limitation
rule can be set on interface or interface+VLAN.
The maximum group limitation rule sets the actions for reaching the maximum number of
multicast group users added, which can be no longer allowing user adding groups, or covering
the original adding group.
IGMP filtering is usually used with MVR.
5.2 Configuring IGMP Snooping
5.2.1 Preparing for configurations
Scenario
Multiple hosts belonging to the same VLAN receive data from the multicast source. Enable
IGMP Snooping on the Layer 2 device that connects the multicast router and hosts. By
listening IGMP packets transmitted between the multicast router and hosts, creating and
maintaining the multicast forwarding table, you can implement Layer 2 multicast.
Prerequisite
Create a VLAN, and add related interfaces to the VLAN.
5.2.2 Default configurations of IGMP Snooping
Global IGMP Snooping status
VLAN IGMP Snooping status
