Explanation
The number of registration of multicast addresses allowed on the entire system exceeded

z Up to 128 multicast MAC addresses can be registered on the entire system.
Therefore, if IGMP snooping is used by multiple VLANs, care must be taken not to exceed the limit number of multicast
MAC addresses.
z Sets the maximum number of multicast groups not to exceed the number of multicast groups that Is registered
currently.
Example
Set the number of groups that can be registered for IGMP snooping on VLAN 2 to 50.
