Chapter 5 Unknown Multicast Packet Drop
Configuration
5.1 Overview
Generally, if the multicast address of the multicast packet received on the switch is not
registered on the local switch, the packet will be broadcast in the VLAN. When the
unknown multicast packet drop feature is enabled, the switch will drop the received
multicast packet whose multicast address is not registered. Thus, the bandwidth is
saved and the processing efficiency of the system is improved.
