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 IPv4 basic ACL rule are the multicast group addresses specified in IGMP reports. The
source and destination addresses specified in the IPv4 advanced ACL rule are the multicast source
addresses and multicast group addresses specified in IGMP reports. 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.
version-number: Specifies an IGMP version, in the range of 1 to 3. By default, the configured group filter
applies to IGMP reports of all versions.
Usage guidelines
If you configure the interface as a static member interface for a multicast group or a multicast source and
group, this configuration has no effect on the multicast group or the multicast source and group.
Examples
# Configure an IPv4 ACL so that hosts on VLAN-interface 100 can join the multicast group 225.1.1.1 only.
