Properties
availEnabled Specifies whether or not collection of availability statistics is enabled for the specified session's LMM test

type=ethernetoam.LmmAvailAdminState
default=disabled
Displayed(tab/group)=Availability (/Timing)

chliThreshold Specifies the MEF-35 Consecutive High Loss Intervals (CHLI) threshold for the specified session's loss (e.fg: SLM or LMM) test. An attempt to change ChliThreshold to a value greater than or equal to tmnxOamPmCfgLossSlmConsecDeltaTs will be rejected.

type=int
default=5
minimum=1
maximum=9
Displayed(tab/group)=CHLI Threshold (/Timing)

clear.ClearRequest-Set type=Children-Set
consecDeltaTs Specifies the number of consecutive MEF-35 'delta_t's (also known as 'Small Time Intervals') which constitute a MEF-35 'Availability Window.

type=int
default=10
minimum=2
maximum=10
Displayed(tab/group)=Consec Delta-T's (/Timing)

fcCollectionEnabled Specifies the administrative state of the collection of Forwarding Class (FC) statistics for the specified LMM test.

type=boolean
default=false
Displayed(tab/group)=Forward Class Collection (/Forwarding Class Statistics)

flrThreshold Specifies the MEF-35 Frame Loss Ratio (FLR) threshold for the specified session's loss (e.g: SLM or LMM) test. The FLR threshold is used to decide if a MEF-35 Small Time Interval (also known as delta_t) is Available or Unavailable.

type=int
default=50
minimum=0
maximum=100
units=percent
Displayed(tab/group)=flr Threshold (/Timing)

hliForceCountEnabled Specifies whether or not to count High Loss Intervals (HLIs) and Consecutive High Loss Intervals (CHLIs) when the LMM test's MEF-35 Availability state is Unavailable. 'true(1)' breaks compliance with MEF-35 by ensuring HLIs and CHLIs are counted in Unavailable periods. 'false(2)' maintains compliance with MEF-35 by preventing HLIs and CHLIs from being counted in Unavailable periods.

type=boolean
default=false
Displayed(tab/group)=HLI Force Count (/Timing)

interval Specifies the elapsed time between transmission of Y.1731 PDUs for the specified session's CFM test. Valid values ( 100 | 1000 | 10000).

type=ethernetoam.LmmSessionInterval
default=1000
minimum=100
maximum=10000
Displayed(tab/group)=Interval (/Timing)

sas.LossTCAConfig-Set type=Children-Set
txFrmsPerDelT The value of tmnxOamPmCfgLossLmmTxFrmsPerDelT specifies the number of Y.1731 loss frames to send in one MEF-35 'delta_t' (also known as 'Small Time Interval') for the specified session's loss (e.fg: SLM or LMM) test. Expressed in milliseconds, delta_t =tmnxOamPmCfgLossSlmTxFrmsPerDelT*tmnxOamPmCfgLossSlmInterval.

type=int
default=10
minimum=1
maximum=50
units=packets
Displayed(tab/group)=Frames Per Delta-T (/Timing)

Methods

requestClearOamPmLmmRawStats

Request clearing of OAM PM Raw Stats. When this method returns resources for the clear have been allocated but the clear has not been performed yet. To retrieve the result eventually, use the returned request handle as input param of the retrieveClearRequest method of the clear.ClearCommandManager.
Input Parameters:
deployer : Deployer - the deployment state
synchronousDeploy : boolean - (Optional) Specify whether to block until the changes have been fully deployed to the network. A value of "true" means to block. A value of "false" means to return immediately. Default: false (asynchronous)
clearOnDeployFailure : boolean - (Optional) Specify whether to clear any failed deployers. A value of "true" means to clear. A value of "false" means to leave the failed deployer. Default: false
deployRetries : int - (Optional) The number of times to attempt re-deployment during synchronous deployment. This parameter is meaningless in the asynchronous case. Default: 0
deployRetryInterval : long - (Optional) The number of milliseconds to wait between deployment retries. This parameter is meaningless in the asynchronous case. Default: 0
taskDescription : string - (Optional) A user friendly description of what the operation does. This information will be used by the task manager.
instanceFullName : string - the full name of the object.
resultFilter : ResultFilter - (Optional) Filter for narrowing down the information returned per object
continueOnFailure : continueOnFailure - (Optional) Continue processing requests in this stream if an exception occurs, unless the request is invalid. Default: false
Output Parameters:
aOutResult : clear.RequestHandleStruct - A request handle which allows the retrieval of the request (and its result when it becomes available) through the ClearCommandManager's retrieveClearRequest method.
