group-policy (IGMP-snooping view)

Syntax
group-policy acl-number [ vlan vlan-list ]
undo group-policy [ vlan vlan-list ]
View
IGMP-snooping view
Default level
2: System level
Parameters
acl-number: Specifies a basic or advanced ACL number, in the range of 2000 to 3999. The source
address or address range specified in the advanced ACL rule matches the multicast source addresses
specified in IGMPv3 reports, rather than the source address in the IP packets. The system assumes that an
IGMPv1 or IGMPv2 report or an IGMPv3 IS_EX or TO_EX report that does not carry a multicast source
address carries a multicast source address of 0.0.0.0.
vlan vlan-list: Specifies one or multiple VLANs. You can provide up to 10 VLAN lists. For each list, you
can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to
end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The value range of a VLAN
ID is 1 to 4094. If you do not specify any VLAN, the command takes effect for all VLANs. If you specify
one or more VLANs, the command takes effect for the specified VLANs only.
Description
Use group-policy to configure a global multicast group filter, namely, to control the multicast groups that
a host can join.
Use undo group-policy to remove the configured global multicast group filter.
By default, no global multicast group filter is configured. Namely, a host can join any valid multicast
group.
If the specified ACL does not exist or the ACL rule is null, all multicast groups are filtered out.
You can configure different ACL rules for a port in different VLANs. For a given VLAN, a newly
configured ACL rule overrides the existing one.
