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 percent (default is 50 percent). 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 percent (default is 75 percent).
Burst Size
settings are only available when the
Burst Test
is enabled (see
EtherSAM - Global on page 137).

Burst Size unit choices are
Bytes
(default) or
ms
.
1. The minimum rate is 1Mbit/s when the Frame Size is Random .
