CIR:
Committed Information Rate. This is the guaranteed maximum rate at which the customer can send frames that are
assured to be forwarded through the network without being dropped. Tap on the box to enter a rate and choose between IR
Mbps
or ULR Mbps. Allowed values range from 0.01Mbps to the line bandwidth.
Information Rate (IR):
Measures the average Ethernet frame rate starting at the MAC address field and ending at
the CRC.
Utilized Line Rate (ULR):
Measures the average Ethernet frame rate starting with the overhead and ending at the
CRC.
Excess Information Rate (EIR):
Maximum rate above the CIR at which the customer can send frames that will be
forwarded on a best effort basis, but may be dropped in the event of congestion within the network. The combined CIR and
EIR must not exceed the line bandwidth. Traffic beyond CIR + EIR will be dropped when it enters the carrier's network. Tap
on the box to enter a rate. EIR is expressed in terms IR Mbps or ULR Mbps. Select a term to express EIR or select
Disable
to disable the test.
Traf. Policing:
Enable or Disable the traffic policing test. For this test, traffic is transmitted at 25% higher than the CIR+EIR.
The Policing test fails if the higher traffic rate is allowed through the network.
Color Mode:
Enable, Disable. When Color Mode is enabled, the Drop Eligible parameter in the VLAN header configuration
screen becomes grayed out and cannot be configured. If no VLAN is configured for the service traffic, the Color Mode
parameter is ignored.
CBS
and EBS: Committed Burst Size (CBS) and Excess Burst Size (EBS).
CBS can be enabled without enabling EBS
If EBS is enabled, then CBS is automatically enabled too
Values between 4 KBytes and 100 KBytes can be input for both CBS and EBS
13.2.3 Services - Thresholds Settings
The user establishes Pass/Fail test criteria for the following Service Acceptance Criteria. Values define the minimum requirements
to ensure that the service meets the Service Level Agreement (SLA):
FLR:
Ratio of lost frames to the total transmitted frames.
FTD:
Measures the transfer time that the frames can take to travel from source to destination. Values are measured in us,
ms, or sec. Input a value within the digital range of .001-999 and 1 us-999sec. The user can also choose to Disable the
FTD threshold evaluation. FTD will be measured regardless, but the value will not contribute toward passing or failing the
service.
IFDV:
Measures the frame jitter.
AVAIL:
The service becomes unavailable if more than 50% of the frames are errored or missing in a one second interval.
Availability is only guaranteed for traffic conforming to the CIR. Enter a percentage from 0-100. The user can also choose to
Disable
the AVAIL threshold evaluation. AVAIL will be measured regardless, but the value will not contribute toward
