Parameters
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 value range for the VLAN ID is 1
to 4094. If you do not specify a VLAN, the command applies to all VLANs.
Usage guidelines
This feature enables the switch to immediately remove a port from the forwarding entry for an IPv6
multicast group when the port receives a done message.
This command and the mld-snooping fast-leave command have the same function but different effective
ranges:
• The fast-leave command in MLD-snooping view takes effect on all ports.
• The mld-snooping fast-leave command takes effect on the current port.
For a port, the mld-snooping fast-leave command takes priority over the fast-leave command in
MLD-snooping view.
Examples
# Globally enable fast-leave processing for VLAN 2.
<Sysname> system-view
[Sysname] mld-snooping
[Sysname-mld-snooping] fast-leave vlan 2
Related commands
mld-snooping fast-leave
group-policy (MLD-snooping view)
Use group-policy to configure a global IPv6 multicast group policy to control the IPv6 multicast groups
that receiver hosts can join.
Use undo group-policy to remove the configured global IPv6 multicast group policy.
Syntax
group-policy acl6-number [ vlan vlan-list ]
undo group-policy [ vlan vlan-list ]
Default
IPv6 multicast group policies are not configured, and receiver hosts can join IPv6 multicast groups.
Views
MLD-snooping view
Predefined user roles
network-admin
Parameters
acl6-number: Specifies an IPv6 basic or advanced ACL by its number in the range of 2000 to 3999.
Receiver hosts can join only IPv6 multicast groups that the ACL permits. If the ACL does not exist or the
ACL does not contain valid rules, receiver hosts cannot join IPv6 multicast groups.
