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 globally for all ports in IGMP-snooping view or for a port in
interface 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 a multicast group address.
To match the following IGMP reports, set the
source-wildcard
IGMPv1 and IGMPv2 reports.

IGMPv3 IS_EX and IGMPv3 TO_EX reports that do not carry multicast source addresses.
