This RowStatus object triggers the actual clear operation, removing Neighbor Binding Table entries that match whatever combination of VLAN tag, source address, interface, or MAC address filter objects were set beforehand. An admin cares because it is the commit step that turns the filter criteria into an actual table-clearing action; without setting this, the filter objects alone do nothing. For example, after setting rlNbrBindingIntegrityClearIfIndex to port Gi1/0/20's index, setting this to createAndGo(4) actually removes that port's binding entries.
