Configuring Simple Shared Shaper Algorithm Variables
The convergence factor determines how quickly the dynamic shaping rate
converges with the calculated dynamic shaping rate, and is expressed as a
percentage of the available bandwidth.
The range for the convergence factor is 0–99 percent, with 0 being the most
liberal and 99 the most conservative. The default value is 50.
(Optional) Configure the specify the reaction factor for all simple shared shapers
on the router.
host1(config-qos-shared-shaper-control)#reaction-factor 50
The reaction factor determines how the shared shaper reacts to changes in the
measured rate.
The range for the reaction factor is 0–1000; 0 is the most liberal and 1000 is the
most conservative. The default value is 200.
(Optional) Specify the minimum value of the dynamic shaping rate as a
percentage of the shared shaping rate for all simple shared shapers on the router.
host1(config-qos-shared-shaper-control)#minimum-dynamic-rate-percent 50
The range for the minimum dynamic rate value is 0 100 percent. The default
value is 0.
(Optional) Configure a maximum value for the virtual output queue length (VOQL)
for all simple shared shapers on the router.
host1(config-qos-shared-shaper-control)#maximum-voql 25
The VOQL tracks the amount of data over queued between simple shared-shaper
rate periods.
The range for the maximum VOQL value is 0–10000 milliseconds (ms). The
default value is 4000.
