# Configuring Simple Shared Shaper Algorithm Variables

To configure the variables for all simple shared shapers on the router:

1. Enter QoS Shared Shaper Control Configuration mode.
   host1(config)#qos-shared-shaper-control host1(config-qos-shared-shaper-control)#
2. (Optional) Configure the convergence factor for all simple shared shapers on the router.
   host1(config-qos-shared-shaper-control)#convergence-factor 25

   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.

3. (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.

4. (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.
5. (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.
