When dot12DesiredFramingType is 'frameTypeEither', dot12CurrentFramingType shall be one of 'frameType88023' or 'frameType88025' when the dot12Status is 'opened'. When the dot12Status is anything other than 'opened', dot12CurrentFramingType shall take the value of 'frameTypeUnknown'." ::= { dot12ConfigEntry 1 } dot12DesiredFramingType OBJECT-TYPE SYNTAX INTEGER { frameType88023(1), frameType88025(2), frameTypeEither(3) } MAX-ACCESS read-write STATUS current DESCRIPTION "The type of framing which will be requested by the interface during the next interface MAC initialization or open action. In master mode, this is the framing mode which will be granted by the interface. Note that for a master mode interface, this object must be equal to 'frameType88023' or 'frameType88025', since a master mode interface cannot grant 'frameTypeEither'."

Whether the repeater grants the requested mode must be verified by examining the state of the PP bits in the corresponding instance of dot12LastTrainingConfig. In master mode, this object controls whether or not promiscuous mode will be granted by the interface when requested by the lower level device. Note that this object indicates the desired mode for the next time the interface trains. The currently active mode will be reflected in dot12LastTrainingConfig and in ifPromiscuousMode."

Training request frames are received when in master mode, while training response frames are received in slave mode. On master mode interfaces, this object contains the contents of the requested configuration field of the most recent training request frame. On slave mode interfaces, this object contains the contents of the allowed configuration field of the most recent training response frame. The format of the current version of this field is described in section 3.8. Please refer to the most recent version of the IEEE 802.12 standard for the most up-to-date definition of the format of this object."

The progress and success of the open is given by the values of the dot12Status object. Setting this object to 'open' when dot12Status has a value other than 'closed' has no effect. Setting the corresponding instance of ifAdminStatus to 'up' when the current value of dot12Status is 'closed' will have the same effect as setting this object to 'open'. Setting ifAdminStatus to 'up' when dot12Status has a value other than 'closed' has no effect. Setting the value of this object to 'close' will move this interface into the 'closed' state and cause all transmit and receive actions to stop. This object will then have to be set to 'open' in order to reinitiate training. Setting the corresponding instance of ifAdminStatus to 'down' will have the same effect as setting this object to 'close'. Setting the value of this object to 'reset' when the current value of dot12Status has a value other than 'closed' will reset the interface. On a reset, all MIB counters should retain their values. This will cause the MAC to initiate an acInitializeMAC action as specified in IEEE 802.12. This will cause training to be reinitiated on this interface. Setting this object to 'reset' when dot12Status has a value of 'closed' has no effect. Setting this object to 'reset' has no effect on the corresponding instance of ifAdminStatus. Setting the value of this object to 'noOp' has no effect. When read, this object will always have a value of 'noOp'." REFERENCE "IEEE Standard 802.12-1995, 13.2.5.2.2, acOpen, acClose, acInitializeMAC. Also, RFC1231 IEEE802.5 Token Ring MIB, dot5Commands." ::= { dot12ConfigEntry 7 } dot12Status OBJECT-TYPE SYNTAX INTEGER { opened(1), closed(2), opening(3), openFailure(5), linkFailure(6) } MAX-ACCESS read-only STATUS current DESCRIPTION "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'."

In a Demand Priority network, end node interfaces typically operate in slave mode, while switch interfaces may control the Demand Priority protocol and operate in master mode. This object may be implemented as a read-only object by those agents and interfaces that do not implement software control of master mode. In particular, interfaces that cannot operate in master mode, and interfaces on which master mode is controlled by a pushbutton on the device, should implement this object read-only. Some interfaces do not require network management configuration of this feature and can autosense whether to use master mode or slave mode. The value 'learn' is used for that purpose. While autosense is taking place, the value 'learn' is returned. A network management operation which modifies the value of dot12ControlMode causes the interface to retrain." ::= { dot12ConfigEntry 9 } dot12StatTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot12StatEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Statistics for a collection of 802.12 interfaces attached to a particular system." ::= { dot12MIBObjects 2 } dot12StatEntry OBJECT-TYPE SYNTAX Dot12StatEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Statistics for a particular interface to an 802.12 medium.
