SLA Parameters
The Service-Level Agreement (SLA) parameters allow enabling and
defining the pass/fail verdict thresholds for the service.
For Dual Test Set, parameters are configurable for both local to remote
(L -> R) and remote to local (R -> L) directions at the exception of Max
Round-Trip Latency for which the value is unique.
Information Rate

Unit choices are % (default), Mbit/s, or Gbit/s. This unit is also used for
Total TX Rate and for Test Parameters (Traffic Policing and Burst
Max Rate).
Note: At least one check box (CIR or CIR+EIR) has to be selected. Thus, clearing
the CIR check box while CIR+EIR check box is cleared, will automatically
select the CIR+EIR check box and vice versa.

CIR (Committed Information Rate) check box when selected (default)
sets the service rate guaranteed by the SLA. The threshold value is
configurable from 0.0001
1
to 100% (default is 50%). CIR and preceding
steps are not performed for services that have the CIR check box
cleared.

CIR+EIR check box when selected (cleared by default) sets the best
effort allowed traffic for the service. The EIR (Excess Information Rate)
value is equal to the CIR+EIR value minus CIR. The threshold value is
configurable from 0.0001
1
to 100% (default is 75%).
Burst Size settings are only available when the Burst Test is enabled (see
EtherSAM - Global on page 120).

Burst Size unit choices are Bytes (default) or ms.
1. The minimum rate is 1Mbit/s when the Frame Size is Random.
