Configuring Dropping Unknown Multicast Packets 
Generally, if the multicast address of the multicast packet received on the device is not registered on the 
local device, the packet will be flooded in the VLAN. When the function of dropping unknown multicast 
packets is enabled, the device will drop any multicast packets whose multicast address is not registered. 
Thus, the bandwidth is saved and the processing efficiency of the system is improved.
