Configuring Dropping Unknown Multicast Packets; Displaying And Maintaining Common Multicast Configuration - 3Com WX3000 Series Operation Manual

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.
Follow these steps to configure dropping unknown multicast packet:
