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 ten 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 this option is not specified, this command takes effect for all VLANs.
Usage guidelines
This command takes effect 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 does not take effect on the multicast group.
Examples
# Set the maximum number of multicast groups that Ethernet 1/1 in VLAN 2 can join to 10.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] 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. A
host can join only the multicast groups that match the permit statement in the specified ACL. The source
addresses in the basic rule are the multicast group addresses specified in IGMP reports. The source and
destination addresses in the advanced ACL rule are the multicast source addresses and multicast group
addresses specified in IGMP reports, respectively. The system assumes that 0.0.0.0 is the multicast source
address of an IGMPv1 or IGMPv2 report or an IGMPv3 IS_EX and TO_EX report that does not carry a
multicast source address.
