R2511-HP MSR Router Series IP Multicast Command Reference(V5)

393
If you do not specify any VLAN when using this command in port group view, the command takes effect
on all the ports in this group. If you specify one or multiple VLANs, the command takes effect only on
those ports in this group that belong to the specified VLANs.
Examples
# Configure the device to allow Ethernet 1/1 in VLAN 2 to join up to 10 IPv6 multicast groups.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] mld-snooping group-limit 10 vlan 2
Related commands
mld group-limit
mld-snooping group-policy
Use mld-snooping group-policy to configure an IPv6 multicast group filter on a port to control the IPv6
multicast groups that the hosts on the port can join.
Use undo mld-snooping group-policy to remove the configured IPv6 multicast group filter.
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, and the hosts on the port can join any valid IPv6
multicast group.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view, port group view
Default command level
2: System level
Parameters
acl6-number: Specifies a basic or advanced IPv6 ACL 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 IPv6 source
addresses specified in the advanced IPv6 ACL rule are the IPv6 multicast source addresses specified in
MLDv2 reports, rather than the source addresses in the IPv6 packets. The system assumes that an MLDv1
report or an MLDv2 IS_EX or TO_EX report that does not carry an IPv6 multicast source address carries
an IPv6 multicast source address of 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.
Usage guidelines
If you do not specify any VLAN when using this command in Layer 2 Ethernet interface view or Layer 2
aggregate interface view, the command takes effect on all VLANs that the interface belongs to. If you
specify one or multiple VLANs, the command takes effect on the specified VLANs that the interface
belongs to.
