dot12 Status

1.3.6.1.3.63.1.1.1.8

The current interface status with respect to training. One of the following values: opened - Training has completed successfully. closed - MAC has been disabled by setting dot12Commands to 'close'. opening - MAC is in training. Training signals have been received. openFailure - Passed 24 error-free packets, but there is a problem, noted in the training configuration bits (dot12LastTrainingConfig). linkFailure - Training signals not received, or could not pass 24 error-free packets. Whenever the dot12Commands object is set to 'close' or ifAdminStatus is set to 'down', the MAC will go silent, dot12Status will be 'closed', and ifOperStatus will be 'down'. When the value of this object is equal to 'closed' and the dot12Commands object is set to 'open' or the ifAdminStatus object is set to 'up', training will be initiated on this interface. When the value of this object is not equal to 'closed' and the dot12Commands object is set to 'reset', training will be reinitiated on this interface. Note that sets of some other objects (e.g. dot12ControlMode) or external events (e.g. MAC protocol violations) may also cause training to be reinitiated on this interface. When training is initiated or reinitiated on an interface, the end node will send Training_Up to the master and initially go to the 'linkFailure' state and ifOperStatus will go to 'down'. When the master sends back Training_Down, dot12Status will change to the 'opening' state, and training packets will be transferred. After all of the training packets have been passed, dot12Status will change to 'linkFailure' if 24 consecutive error-free packets were not passed, 'opened' if 24 consecutive error-free packets were passed and the training configuration bits were OK, or 'openFailure' if there were 24 consecutive error-free packets, but there was a problem with the training configuration bits. When in the 'openFailure' state, the dot12LastTrainingConfig object will contain the configuration bits from the last training packet which can be examined to determine the exact reason for the training configuration failure. If training did not succeed (dot12Status is 'linkFailure' or 'openFailure), the entire process will be restarted after MAC_Retraining_Delay_Timer seconds. If training does succeed (dot12Status changes to 'opened'), ifOperStatus will change to 'up'. If training does not succeed (dot12Status changes to 'linkFailure' or 'openFailure'), ifOperStatus will remain 'down'.
