+    DESCRIPTION
+        "The Storm-Constrain function is used to avoid the
+         packet-storm on a port.  Three types of flux can be
+         set observed respectively: broadcast, multicast and
+         unicast.  If an observed flux exceeds its upper limit,
+         this kind of flux will be recognized as over-upper-flux.
+         This kind of flux will be considered as normal-flux
+         until it falls below its lower limit.  If any type of
+         observed flux is over-upper-flux, the port will change
+         its status to controlled-status, that is to stop packet
+         forwarding to avoid storm.  Only when all the observed
+         fluxes are not over-upper-flux, will the port return to
+         normal(forwarding) status."
