Article summary

Setting the Working Rate

You must select the layer (Layer-1 or Layer-2) used by the unit to determine the rate for the traffic generators, traffic regulators and traffic shapers. For example, if you setup a traffic regulator with a CIR of 20,000 kbps, you want to tell the unit which bytes are used in the calculation of the CIR: Layer-1 bytes or Layer-2 bytes. 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 and 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. For example, when using a traffic generator with an in-service flow type, you must ensure the Regulator working rate and the Generator working rate are both set to the same layer (Layer-1 or Layer-2) in order to have accurate tests.

To set the working rate

  1. Access the page System ▶Configuration ▶Traffic ▶Rate

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

For more information on specific parameters, refer to the table in Selecting "Selecting VLAN level settings"

Selecting VLAN level settings

The VLAN level for each Traffic Port must be configured to be used with one or two VLAN tags in the VLAN filters.

When the VLAN level setting is configured as "Outer" (default), then the VLAN filter is matched against the outer VLAN of incoming frames. With this option, the outer VLAN ID can only be used once per port in the VID sets.

When the VLAN level setting is configured as "Inner", then the VLAN filter is matched against both outer and inner VLANs of incoming frames. With this option, the inner VLAN ID can only be used once per port in the VID sets.

In all cases, the VLAN type must match the filters.

To select the VLAN filtering option

  1. Access the page Traffic ▶Configuration.

  2. Select the VLAN on which you want to filter for each policy list, then click Apply.

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

Shaper Working Rate

The layer used by the unit to determine the working rate:
  • 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).
