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

Use igmp group-limit to configure the maximum number of multicast groups that an interface can join.
Use undo igmp group-limit to restore the default.
By default, the upper limit is 2000.
This command is effective only for dynamically joined multicast groups but not statically joined multicast
groups.
If the configured limit value is smaller than the number of the existing multicast groups on the current
interface, the system does not automatically remove the multicast groups in excess. To bring this
configuration into effect in this case, use the reset igmp group command to clear the IGMP group
information manually.
You can also use the igmp-snooping group-limit command to limit the number of 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. HP recommends you to configure the limit only on the VLAN interface.
Related commands: igmp static-group, igmp-snooping group-limit, and reset igmp group.
Examples
# Allow VLAN-interface 100 to join up to 128 multicast groups.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] igmp group-limit 128

undo igmp group-policy
View

Default level
2: System level
Parameters
acl-number: Basic or advanced ACL number, in the range of 2000 to 3999. The source address or
address range specified in the advanced ACL rule matches the multicast source address or addresses
specified in IGMPv3 reports, rather than the source address in the IP packets. The system assumes that an
IGMPv1 or IGMPv2 report or an IGMPv3 IS_EX and TO_EX report that does not carry a multicast source
address carries a multicast source address of 0.0.0.0.
version-number: IGMP version, in the range of 1 to 3. If you do not specify an IGMP version, the
configured group filter applies to IGMP reports of all versions.
Description
Use igmp group-policy to configure a multicast group filter on the current interface to control the multicast
groups that the hosts on the current interface can join.
Use undo igmp group-policy to remove the configured multicast group filter.
By default, no multicast group filter is configured, and a host can join any valid multicast group.
