A scaling factor used for the WRED calculation to 
determine the packet drop probability for the current 
drop precedence level. The value is specified as a 
number S from 1-15 and is used in the formula: 1/(2**
S), meaning one packet is dropped out of every (2**
S). Packet dropping begins when 
agentCosQueueMgmtWredMinThreshold is reached and 
proceeds linearly up to the (2**S) value specified by 
this object until the 
agentCosQueueMgmtWredMaxThreshold is reached, beyond 
which all packets are dropped. Smaller values of S 
produce a steeper slope, hence a higher incidence of 
randomly dropped packets.  
              
The default value is 10, which corresponds to a drop 
rate of 1 out of every (2**10)=1024 packets.                     
              
This object is only used when agentCosQueueMgmtType 
is set to wred(2).
