This parameter is useful with networks that contain a large
number of multicast groups. You can use the parameter to
prevent the switch’s MAC address table from filling up with
multicast addresses, leaving no room for dynamic or static MAC
addresses. The range is 1 address to 2048 addresses. The default is
256 multicast addresses.
