H3C IE4300 Command Reference Manual page 1527

Usage guidelines
This command takes effect only on the multicast groups that a port joins dynamically.
Examples
# On GigabitEthernet 1/0/1, set the maximum number of multicast groups the port can join in VLAN 2
to 10.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] igmp-snooping group-limit 10 vlan 2
igmp-snooping group-policy
Use
igmp-snooping group-policy
the multicast groups that hosts attached to the port can join.
Use
undo igmp-snooping group-policy
Syntax
igmp-snooping group-policy ipv4-acl-number [ vlan vlan-list ]
undo igmp-snooping group-policy [ vlan vlan-list ]
Default
No multicast group polices exist on a port. Hosts attached to the port can join any multicast groups.
Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
ipv4-acl-number
to 3999. Hosts can join only the multicast groups that the ACL permits. If the ACL does not exist or
does not have valid rules, hosts cannot join multicast groups.
vlan vlan-list
VLAN by its ID or a range of VLANs in the form of
ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect on all VLANs.
Usage guidelines
A multicast group policy filters IGMP reports to control the multicast groups that hosts can join.
This command does not take effect on static member ports, because static member ports do not
send IGMP reports.
You can configure a multicast group policy for a port in interface view or globally for all ports in
IGMP-snooping view. For a port, the port-specific configuration takes priority over the global
configuration.
When you configure a rule in the IPv4 ACL, follow these restrictions and guidelines:
•
In a basic ACL, the
multicast group address.
•
In an advanced ACL, the
multicast source address. The

: Specifies an IPv4 basic or advanced ACL by its number in the range of 2000
: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a
source source-address source-wildcard
source source-address source-wildcard
destination dest-address dest-wildcard
