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
-
Access the page Traffic â–¶ Configuration.
-
Select the working rate to be applied to all entities, then click Apply.
