Configuring the Line Compensation Value for a Rate Meter
(Policer) (CLI)
A rate meter can measure CIR and EIR at Layer 1 or Layer 2 rates. Layer 1 capacity is equal to Layer 2 capacity plus
20 additional bytes for each frame due to the preamble and Inter Frame Gap (IFG). In most cases, the preamble
and IFG equals 20 bytes, but other values are also possible. Line compensation defines the number of bytes to be
added to each frame for purposes of CIR and EIR calculation. When Line Compensation is 20, the rate meter
operates as Layer 1. When Line Compensation is 0, the rate meter operates as Layer 2. This parameter is very
important to users that want to distinguish between Layer 1 and Layer 2 traffic.
To configure the rate meter (policer) line compensation value for an interface, go to interface view for the
interface and enter the following command:
eth type eth [x/x]>rate-meter-compensation-value set <value>
To display the rate meter (policer) line compensation value for an interface, go to interface view for the interface
and enter the following command:
eth type eth [x/x]>rate-meter-compensation-value get

Policers attached to the interface use this
value to compensate for Layer 1 non-
effective traffic bytes.
The following command sets the line compensation value for policers attached to GbE 1 to 20:
eth type eth [1/1]>rate-meter-compensation-value set 20
