Table 5-12. Service Level Verification Performance Statistics (2 of 2)

Statistic

What It Indicates

H Above EIR *

H The number of frames transmitted by the far-end device that

 

were above the excess information rate and were dropped

 

in transit.

 

 

Inbound Dropped

Total number of bytes transmitted by the far-end device that

Characters *

were dropped in transit.

 

The counts continue to increment until the maximum value is

 

reached (232 ±2), then the count starts over.

 

The SLV Delivery Ratio option (see Table 3-2, Service Level

 

Verification Options) must be enabled for these statistics to

 

appear. NA appears instead of a statistical count if FDR/DDR

 

(Frame Delivery Ratio/Data Delivery Ratio) information is not

 

being received from the far-end device .

H Above CIR *

H The number of bytes transmitted by the far-end device that

 

were above the committed information rate and were

 

dropped in transit.

 

 

HWithin CIR *

HThe number of bytes transmitted by the far-end device that were within within the committed information rate, but were dropped in transit.

HBetween CIR&EIR *

HThe number of bytes transmitted by the far-end device that were between the committed information rate and excess information rate, and were dropped in transit.

H Above EIR *

H The number of bytes transmitted by the far-end device that

 

were above the excess information rate and were dropped

 

in transit.

 

 

Latest RdTrip Latency

Current round trip latency, measured in milliseconds, between

 

the FrameSaver unit and the device at the other end of the

 

multiplexed DLCI connection.

 

Unknown appears if communication with the far-end device is

 

not successful.

 

 

Avg RdTrip Latency

Average round trip latency, measured in milliseconds, between

 

the FrameSaver unit and the device at the other end of the

 

multiplexed DLCI connection.

 

Average round trip latency is measured every SLV sampling

 

interval and the average is computed (using packets with the

 

configured SLV Packet Size (bytes), Table 3-2, Service Level

 

Verification Options) over the previous 15-minuteperiod. If

 

SLV Packet Size is changed, a new average is not available

 

until a new sample has been received.

 

Unknown appears if communication with the far-end device

 

over the last 15 minutes has not been successful.

 

 

Max RdTrip Latency

Same as average (Avg RdTrip Latency), but storing the

 

maximum value of latency over the previous 15-minute

 

interval.

 

Unknown appears if communication with the far-end device

 

over the last 15 minutes has not been successful.

 

 

*Only appears for FrameSaver units when the SLV Delivery Ratio option is enabled.
