Mld Group-Policy - HP 3600 v2 Series Command Reference Manual

Description
Use mld group-limit to configure the maximum number of IPv6 multicast groups that an interface can
join.
Use undo mld group-limit to restore the default.
By default, the upper limit is 1000.
This command is effective only for dynamically joined IPv6 multicast groups but not statically joined IPv6
multicast groups.
If the configured limit value is smaller than the number of the existing IPv6 multicast groups on the current
interface, the system does not automatically remove the IPv6 multicast groups in excess. To bring this
configuration into effect in this case, you need to use the reset mld group command to clear the IPv6
multicast groups information manually.
You can also use the mld-snooping group-limit command to limit the number of IPv6 multicast groups
that an interface can join. However, if you configure the limit both in a VLAN and on a VLAN interface
of this VLAN by using these two commands, inconsistencies might exist between Layer 2 and Layer 3
table entries. Therefore, HP recommends you to configure the limit only on the VLAN interface.
Related commands: mld static-group, mld-snooping group-limit, and reset mld group.
Examples
# Allow VLAN-interface 100 to join up to 128 IPv6 multicast groups.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] mld group-limit 128

mld group-policy

Syntax
mld group-policy acl6-number [ version-number ]
undo mld group-policy
View
Interface view
Default level
2: System level
Parameters
acl6-number: Specifies a basic or advanced IPv6 ACL, in the range of 2000 to 3999. The source
address or address range specified in the advanced IPv6 ACL rule is the IPv6 multicast source address
or addresses specified in MLDv2 reports, rather than the source address 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.
version-number: MLD version number, 1 or 2. If you do not specify an MLD version, the configured group
filter is effective for MLD reports of both version 1 and version 2.
Description
Use mld group-policy to configure an IPv6 multicast group filter on the current interface to control the IPv6
multicast groups that the hosts on the current interface can join.
