Default level
2: System level
Parameters
limit: Maximum number of multicast groups that an interface can join, in the range of 1 to 2000.
Description
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.
