# AHDLC Engine Details

The AHDLC Engine Details category of the Configure dialog box displays details of the AHDLC (asynchronous high-level data link control) engine.

## Procedure

1. Right-click the device, then select Configure, or double-click the device.

2. Select AHDLC Engine Details from the Category list.

The following information appears:

Engine Index (cCdmaAhdlcEngineIndex)

Engine Name (cCdmaAhdlcEngineName)

Engine Type (cCdmaAhdlcEngineType)

Operational State (cCdmaAhdlcEngineOperState)

Desired State (cCdmaAhdlcEngineAdminState)

Notification Status (cCdmaAhdlcEngineDownNotifEnabled)

Service Adapter Index (cCdmaAhdlcPhysicalIndex)

### Engine Index (cCdmaAhdlcEngineIndex)

Arbitrary non-zero integer-value that uniquely identifies an asynchronous high-level data link control (AHDLC) engine. The engine index is implemented such that AHDLC engines are assigned consecutive monotonically increasing values.

### Engine Name (cCdmaAhdlcEngineName)

Textual name of the asynchronous high-level data link control (AHDLC) engine as assigned by the local device.

### Engine Type (cCdmaAhdlcEngineType)

Asynchronous high-level data link control (AHDLC) engine type. The engine type can be:

- Hardware: a hardware-based engine that requires the use of AHDLC hardware assist. Each hardware-based engine is peer to one unique AHDLC hardware assist.

- Software: a software-based engine that is not peer to an AHDLC hardware assist but relies on the system cpu(s) to perform AHDLC framing.

- Unknown: The engine type cannot be determined.

### Operational State (cCdmaAhdlcEngineOperState)

Asynchronous high-level data link control (AHDLC) engine operational state. The state can be up or down.

The up state means the engine is ready to receive ahdlc packets.

If cCdmaAhdlcEngineAdminState is down then cCdmaAhdlcEngineOperState should also be down.

If cCdmaAhdlcEngineAdminState is changed to up then cCdmaAhdlcEngineOperState should change to up if the engine is ready to receive ahdlc packets; it should remain in the down state only if there is a fault that prevents it from going to the up state.

### Desired State (cCdmaAhdlcEngineAdminState)

Desired state of the asynchronous high-level data link control (AHDLC) engine. Initially all interfaces start in the down state. As a result of either explicit management action or based on the configuration information retained by the managed system, cCdmaAhdlcEngineAdminState is then changed to up or retained in the down state.

### Notification Status (cCdmaAhdlcEngineDownNotifEnabled)

Indicates if a notification will be sent out when cCdmaAhdlcEngineAdminState is up and cCdmaAhdlcEngineOperState is down. The notification is sent if the value of the object is true.

### Service Adapter Index (cCdmaAhdlcPhysicalIndex)

Entry in the ENTITY-MIB (RFC-2737) corresponding to the asynchronous high-level data link control (AHDLC) service adapter. The value of the object is the entPhysicalIndex value corresponsing to the service adapter or 0 if the entPhysicalIndex cannot be determined or is not applicable.
