Parameters
acl-number: Basic ACL number, defining a multicast group range. The value ranges from 2,000 to

1: Configures the interface to accept only IGMPv1 report messages.
2: Configures the interface to accept only IGMPv2 report messages (default).
port interface-list: Configures a multicast group filter on the specified port or ports. With the interface-list
argument, you can define one or more individual ports (in the form of interface-type interface-number)
and/or one or more port ranges (in the form of interface-type interface-number1 to interface-type
interface-number2, where interface-number2 must be greater than interface-number1). The total
number of individual ports plus port ranges cannot exceed 10. For port types and port numbers, refer to
the parameter description in the "Port Basic Configuration" part in this manual.
In LoopBack interface view, this command does not support the port interface-list option.
Description
Use the igmp group-policy command to configure a multicast group filter on the current interface to
control the access to the multicast groups in the defined group range.
Use undo igmp group-policy command to remove the multicast group filter configured.
By default, no filter is configured; that is, a host can join any multicast group.
If you do not want the hosts on the network attached to the interface to join some multicast groups, use
this command to limit the range of the multicast groups served by the interface.
Related commands: igmp host-join.
Be sure that the Ethernet ports specified in the command belong to the VLAN interfaces on which the
command is configured, but not other VLAN interfaces.
