Article summary

Setting the Working Rate

You must select the layer (Layer 1 or Layer 2) used by the Cisco Provider Connectivity Assurance Sensor Control to determine the rate for the traffic generators and traffic regulators. For example, if you set up a traffic generator flow with a bit rate of 20,000 kbps, the remote device must be informed of whic bytes are being used to calculate the bit rate. The working rate options are:

  • Layer-1: Rate calculation is based on the Layer-1 frames sizes, including the size of the Inter-Frame Gap (IFG), Preamble and Start-Frame Delimiter (SFD)
  • Layer-2: Rate calculation is based on the Layer-2 frames sizes, which does not include the size of the Inter-Frame Gap (IFG), Preamble or Start Frame Delimiter (SFD)


Note: Exercise caution when setting up the working rate. You should ensure that you set the different working rates to the same layer when they work together in a particular setup in order to generate accurate test results.

To set the working rate

  1. Access the page Traffic ▶ Configuration.

  2. Select the working rate to be applied to all entities, then click Apply.

For more information on specific parameters, refer to the following table.

ParametersDescription
Generator working rate

Regulator working rate

The layer used by the Sensor Control to determine the working rate for the RFC-2544 generator and testsuite as well as for all bandwidth regulators:
  • Layer-1: Rate calculation is based on the Layer-1 frames sizes, including the size of the Inter-Frame Gap (IFG), Preamble and Start-Frame Delimiter (SFD)
  • Layer-2: Rate calculation is based on the Layer-2 frames sizes, which does not include the size of the Inter-Frame Gap (IFG), Preamble or Start-Frame Delimiter (SFD)
