2.6.4 Configuring the Function of Dropping Unknown Multicast Data
Unknown multicast data refers to multicast data for which no entries exist in the IGMP
Snooping forwarding table. When the switch receives such multicast traffic:
z With the function of dropping unknown multicast data enabled, the switch drops all
