Syntax 
igmp-snooping nonflooding-enable 
undo igmp-snooping nonflooding-enable 
View 
System view 
Parameter 
None 
Description 
Use the igmp-snooping nonflooding-enable command to enable unknown multicast 
data packets not to be broadcasted within a VLAN. 
Use the undo igmp-snooping nonflooding-enable command to disable unknown 
multicast data packets not to be broadcasted within a VLAN. 
Note that if IGMP snooping is not enabled on the VLAN (nor Layer 3 multicast), 
unknown multicast packets are broadcasted within the VLAN no matter whether this 
function is enabled or not. To make unknown multicast data packets not be 
broadcasted within the VLAN, you need to enable igmp-snooping in this VLAN and 
enable igmp-snooping nonflooding-enable globally. 
By default, unknown multicast data packets are broadcasted within the VLAN.
