Parameters
limit: Sets the maximum number of multicast groups that a port can join, in the range of 0 to
4294967295.
vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its
ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094. If you do not specify any VLAN, the command takes effect on all VLANs.
Usage guidelines
This command is effective on the multicast groups that a port joins dynamically. If you configure the port
as a static member port for a multicast group, this command is not effective on the multicast group.
Examples
# Set the maximum number of multicast groups that GigabitEthernet 2/1/1 in VLAN 2 can join to 10.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] igmp-snooping group-limit 10 vlan 2
igmp-snooping group-policy
Use igmp-snooping group-policy to configure a multicast group filter on a port to control the multicast
groups that the hosts on the port can join.
Use undo igmp-snooping group-policy to remove the multicast group filter on a port.
Syntax
igmp-snooping group-policy acl-number [ vlan vlan-list ]
undo igmp-snooping group-policy [ vlan vlan-list ]
Default
No multicast group filter is configured on a port. Namely, the hosts attached to the port can join any valid
multicast group.

Parameters
acl-number: Specifies an IPv4 basic or advanced ACL by its number in the range of 2000 to 3999.
Receiver hosts can join only the multicast groups that the ACL permits. In an IPv4 basic ACL, the source
keyword matches against the multicast group addresses in IGMP reports. In an IPv4 advanced ACL, the
source and destination keywords match against the multicast source addresses and multicast group
