Viewing Delay Measurements Results

  • PDF

Article summary

To view delay measurement results details

  1. Access the page SOAM ▶ CFM ▶ DMM ▶ Results.

    The results for all Delay Measurement Instances are displayed.


    Note: For more information on how delay measurements results are calculated, refer to "Setting Up Delay Measurements".

  2. Click the Index of the DMM instance you want to view the DMM results.

For more information on specific parameters, refer to the following tables.

DMM Results (SOAM ▶ CFM ▶ DMM ▶ Results)

ParameterDescription
IndexThe index of the delay measurement instance
NameThe name of the delay measurement instance
MEP Index

MEP idx

The index assigned to the Maintenance association End Point
MEPIDThe local MEP's Maintenance association End Point Identifier
Remote MEPID

R-MEPID

The remote MEP's Maintenance association End Point Identifier
PriorityThe priority value used in VLAN tags, if present, in the transmitted frame
PeriodThe number of periods that elapsed since measurement started
Period TimeThe time when the previous period was completed
Result CodesThe current value, expressed in microseconds, for DMM results:
  • OAD: One-Way Average Delay
  • OADV: One-Way Average Delay Variation
  • TAD: Two-Way Average Delay
  • TADV: Two-Way Average Delay Variation
Op StatusThe DMM operational status code. Valid values are:
  • INAC: Feature is inactive
  • UNLK: Remote device is unlinked
  • WAPP: Waiting for an application that supports the DMM to become active
  • PROG: Remote device is currently being programmed
  • FAIL: Remote device has encountered a failure
  • ACT: Remote device is active and fully functional

One-Way Delay

ParameterDescription
Average AlarmIndicates whether an alarm is raised (Active) because the current average one-way delay is greater than or equal to the average threshold
Instantaneous AlarmIndicates if an alarm has been raised (Active) because the instantaneous threshold has been reached. This threshold is the consecutive number of times the one-way delay was greater than or equal to the maximum value.
Instantaneous DelayThe one-way instantaneous delay, expressed in microseconds
PeriodGives the results for the previous and current periods

The previous period is indicated in Period Time.

Nbr SamplesTotal number of samples in the period
Minimum DelayThe minimum delay, expressed in microseconds, over one period
Maximum DelayThe maximum delay, expressed in microseconds, over one period
Average DelayThe average delay, expressed in microseconds, over one period
Nbr Threshold ExceededNumber of times the one-way delay exceeded the value of the Maximum Delay parameter

One-Way Delay Variation

ParameterDescription
Average AlarmIndicates if an alarm has been raised (Active) because the current average one-way delay variation is greater than or equal to the average threshold
Instantaneous AlarmIndicates if an alarm has been raised (Active) because the instantaneous threshold has been reached. This threshold is the consecutive number of times the one-way delay variation was greater than or equal to the maximum value.
Instantaneous DVThe one-way instantaneous delay variation, expressed in microseconds
PeriodGives the results for the previous and current periods

The previous period is indicated in Period Time.

Nbr SamplesTotal number of samples in the period
Minimum DVThe minimum delay variation over one period, expressed in microseconds
Maximum DVThe maximum delay variation over one period, expressed in microseconds
Average DVThe average delay variation over one period, expressed in microseconds
Nbr Threshold ExceededNumber of times the one-way delay variation exceeded the value of the Maximum DV parameter

Two-Way Delay

ParameterDescription
Average AlarmIndicates whether an alarm is raised (Active) because the current average two-way delay is greater than or equal to the average threshold
Instantaneous AlarmIndicates if an alarm has been raised (Active) because the instantaneous threshold has been reached. This threshold is the consecutive number of times the two-way delay was greater than or equal to the maximum value.
Instantaneous DelayThe two-way instantaneous delay, expressed in microseconds
PeriodGives the results for the previous and current periods

The previous period is indicated in Period Time.

Nbr SamplesTotal number of samples in the period
Minimum DelayThe minimum delay, expressed in microseconds, over one period
Maximum DelayThe maximum delay, expressed in microseconds, over one period
Average DelayThe average delay, expressed in microseconds, over one period
Nbr Threshold ExceededNumber of times the two-way delay exceeded the value of the Maximum Delay parameter

Two-Way Delay Variation

ParameterDescription
Average AlarmIndicates if an alarm has been raised (Active) because the current average two-way delay variation is greater than or equal to the average threshold
Instantaneous AlarmIndicates if an alarm has been raised (Active) because the instantaneous threshold has been reached. This threshold is the consecutive number of times the two-way delay variation was greater than or equal to the maximum value.
Instantaneous DVThe two-way instantaneous delay variation, expressed in microseconds
PeriodGives the results for the previous and current periods

The previous period is indicated in Period Time.

Nbr SamplesTotal number of samples in the period
Minimum DVThe minimum delay variation over one period, expressed in microseconds
Maximum DVThe maximum delay variation over one period, expressed in microseconds
Average DVThe average delay variation over one period, expressed in microseconds
Nbr Threshold ExceededNumber of times the two-way delay variation exceeded the value of the Maximum DV parameter
