igmp-snooping group-limit

Syntax
igmp-snooping group-limit limit [ vlan vlan-list ]
undo igmp-snooping group-limit [ vlan vlan-list ]
View
Layer 2 Ethernet interface view, Layer 2 aggregate interface view, port group view
Default level
2: System level
Parameters
limit: Specifies the maximum number of multicast groups that a port can join. For the HP 3600 v2 EI
switches, the value ranges from 0 to 2000. For the HP 3600 v2 SI switches, the value ranges from 0 to
1024.
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.
Description
Use igmp-snooping group-limit to set the maximum number of multicast groups that a port can join.
Use undo igmp-snooping group-limit to restore the default.
By default, the upper limit is 2000 for the HP 3600 v2 EI switches, and 1024 for the HP 3600 v2 SI
switches.
For the HP 3600 v2 EI switches, 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 on 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.
