Enabling 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, one of the following occurs:
• When the function of dropping unknown multicast data is disabled, the switch floods unknown
multicast data in the VLAN that the unknown multicast data belongs to, causing network bandwidth
waste and low forwarding efficiency.
• When the function of dropping unknown multicast data is enabled, the switch forwards unknown
multicast data to its router ports instead of flooding it in the VLAN. If no router ports exist, the switch
drops the unknown multicast data.
Configuration guidelines
The configuration in IGMP snooping view and the configuration in VLAN view are mutually exclusive.
Namely, after this function is enabled in IGMP snooping view, it cannot be enabled or disabled in VLAN
view, and vice versa.
Configuration procedure
To enable dropping unknown multicast data globally:
Ste

To enable dropping unknown multicast data in a VLAN:
