The maximum number is 1000
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view, port group view
Default command level
2: System level
Parameters
limit: Specifies the maximum number of multicast groups that a port can join, in the range of 0 to 1000.
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
For a switch that supports both IGMP snooping and IGMP and is installed with the SAP module, you can
also use the igmp 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. Therefore, HP
recommends you to configure the limit only in the VLAN interface.
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 for all VLANs that the interface belongs to. If you
specify one or more VLANs, the command takes effect for the specified VLANs that the interface belongs
to.
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 more VLANs, the command takes effect only on those
ports in this group that belong to the specified VLANs.
Examples
# Configure the device to allow GigabitEthernet 2/0/1 in VLAN 2 to join up to 10 multicast groups.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] igmp-snooping group-limit 10 vlan 2

groups that the hosts on the port can join.
Use undo igmp-snooping group-policy to remove a multicast group filter.
