Services (Configuration)

CIR+EIR 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
CIR+EIR check box is cleared by default.

Rate Unit
allows the selection of
Mbit/s
(default) or
Gbit/s
as the rate
unit for CIR , CIR+EIR , Ramp Traffic Policing Rate , and Burst Max
Rate
.
Note:
Changing a criteria value (CIR, CIR+EIR, Ramp Traffic Policing, or Burst
Max Rate) may affect the other criteria values in order to comply to the
following rules:
CIR

CIR+EIR

Ramp Traffic Policing Rate

Line Rate
CIR

CIR+EIR

Burst Max Rate

Line Rate
However, make sure that the criteria values comply to the following rule
with an adequate margin, as per ITU-T Y.1564 standard, for a burst test to
be valid:
CIR

CIR+EIR

Burst Max Rate

Line Rate
Note:
The minimum rate is 1Mbit/s when the Frame Size is Random .
Burst Size

CBS
sets the maximum committed burst size to which services’ frames
will be sent and be CIR-compliant. The CBS minimum and maximum
values are affected by the
CIR
,
Burst Max Rate
, and
Frame Size
values. CBS is only available when Burst Test (see page 328) and CIR
are enabled.

EBS sets the maximum excess burst size to which services’ frames will
be sent and be CIR+EIR compliant. The EBS minimum and maximum
values are affected by the
CIR+EIR , Burst Max Rate , and Frame Size
values.
EBS
is only available when
Burst Test
(see page 328) and
CIR+EIR are enabled.

Burst Unit
allows the selection of
Bytes
(default) or
ms
as the burst
size unit for CBS and EBS .
