Examples
# On GigabitEthernet 1/0/1, set the maximum number to 10 for IPv6 multicast groups that the port
can join in VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] mld-snooping group-limit 10 vlan 2
mld-snooping group-policy
Use
mld-snooping group-policy
control the IPv6 multicast groups that hosts attached to the port can join.
Use
undo mld-snooping group-policy
Syntax
mld-snooping group-policy ipv6-acl-number [ vlan vlan-list ]
undo mld-snooping group-policy [ vlan vlan-list ]
Default
No IPv6 multicast group policies exist. Hosts attached to the port can join any IPv6 multicast groups.
Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
ipv6-acl-number
3999. Hosts can join only the IPv6 multicast groups that the ACL permits. If the ACL does not exist or
does not have valid rules, hosts cannot join IPv6 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
An IPv6 multicast group policy filters MLD reports to control the IPv6 multicast groups that hosts can
join.
This command does not take effect on static member ports, because static member ports do not
send MLD reports.
You can configure an IPv6 multicast group policy for a port in interface view or globally for all ports in
MLD-snooping view. For a port, the port-specific configuration takes priority over the global
configuration.
When you configure a rule in the IPv6 ACL, follow these restrictions and guidelines:
•
In a basic ACL, the
multicast group address.
•
In an advanced ACL, the
IPv6 multicast source address. The
