Information
By default this command is disabled. When enabled, all the Layer 3 unicast routed data traffic
going through a VLAN member port is flooded across all the member ports of that VLAN.
There might be some ARP table entries which are resolved through ARP packets which had
Ethernet MAC SA different from MAC information inside the ARP packet. This unicast data
traffic flooding occurs only for those packets which use these ARP entries.
