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.
