R211x-HP Flexfabric 11900 IP Multicast Command Reference

140
Syntax
mld-snooping group-policy acl6-number [ vlan vlan-list ]
undo mld-snooping group-policy [ vlan vlan-list ]
Default
No IPv6 multicast group filter is configured on a port. Namely, the hosts attached to the port can join any
valid IPv6 multicast group.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
mdc-admin
Parameters
acl6-number: Specifies a basic or advanced IPv6 ACL by its number in the range of 2000 to 3999. A
host can join only the IPv6 multicast groups that match the permit statement in the specified ACL. The
source addresses in the basic IPv6 rule are the IPv6 multicast group addresses specified in MLD reports.
The source and destination addresses in the advanced IPv6 ACL rule are IPv6 multicast source addresses
and multicast group addresses specified in MLD reports, respectively. The system assumes that 0::0 is the
multicast source address of an MLDv1 report or an MLDv2 IS_EX and TO_EX report that does not carry
an IPv6 multicast source address.
vlan vlan-list: Specifies a space-separated list of up to 10 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
If the specified ACL does not exist or the ACL rule is null, all IPv6 multicast groups are filtered out.
You can configure different ACL rules on a port in different VLANs. However, for a given VLAN, a newly
configured ACL rule overrides the existing one.
This command takes effect for the IPv6 multicast groups that a port dynamically joins. If you configure the
port as a static member port for an IPv6 multicast group, this command does not take effect for the IPv6
multicast group.
The configuration made in proper interface view is only effective on the current port and takes preference
over the global configuration.
Examples
# Apply ACL 2000 as an IPv6 multicast group filter on Ten-GigabitEthernet 1/0/1 in VLAN 2 so that
hosts attached to the port can join only the multicast group FF03::101.
