Use the igmp group-policy command to configure the filtering rule of multicast 
groups on a specified VLAN so as to control the access to IP multicast groups. You 
can configure only one ACL rule for each VLAN, and the new configured rule will 
replace the old one.

Use the undo igmp group-policy command to cancel the configuration.

By default, no filtering rule is set in a VLAN. In this case, a host can join any 
multicast group.

# Create ACL2001 and configure the flow rule for basic ACL, using the source IP 
address serves as the destination multicast address.

group-address: Multicast address of the multicast group that an interface will join.

interface-type interface-number [ to interface-type interface-number ]: Specifies 
the port under the interface.

Use the igmp host-join command to enable a port in the interface of an Ethernet 
switch to join a multicast group.
