This describes the mandatory OIDs for FDDI objects, both operational and statistical types.
FDDI Operational Characteristics
The following chart summarizes the mandatory OIDs used to get or set FDDI operational characteristics for NDIS drivers and NICs.
| Length | Q | S | Name |
| 6 | M | OID_FDDI_LONG_PERMANENT_ADDR Permanent station address |
|
| 6 | M | OID_FDDI_LONG_CURRENT_ADDR Current station address |
|
| Arr(6) | M | M | OID_FDDI_LONG_MULTICAST_LIST Multicast list |
| 4 | M | OID_FDDI_LONG_MAX_LIST_SIZE Maximum list size |
|
| 2 | M | OID_FDDI_SHORT_PERMANENT_ADDR Permanent station address |
|
| 2 | M | OID_FDDI_SHORT_CURRENT_ADDR Current station address |
|
| Arr(2) | M | M | OID_FDDI_SHORT_MULTICAST_LIST Multicast list |
| 4 | M | OID_FDDI_SHORT_MAX_LIST_SIZE Maximum list size |
The following describes each of the OID_XXX listed in the preceding chart more fully.
The address of the NIC encoded in the hardware.
The address the NIC is currently using.
The network management software cannot set the current station address using the NDIS interface library. It must set this address as a configuration parameter.
The list of multicast addresses the NIC is currently using.
The maximum size multicast list the NIC supports.
The address of the NIC encoded in the hardware.
The address the NIC is currently using.
The network management software cannot set the current station address using the NDIS interface library. It must set this address as a configuration parameter.
The list of multicast addresses the NIC is currently using.
The maximum size multicast list the NIC supports.
FDDI Statistics
The following chart summarizes the mandatory OIDs used to get FDDI statistics from underlying NIC drivers (or from NDIS).
| Length | Q | S | Name |
| 4 | M | OID_FDDI_ATTACHMENT_TYPE The direction of traffic on the ring |
|
| 6 | M | OID_FDDI_UPSTREAM_NODE_LONG The long address of the station above this NIC on the ring |
|
| 6 | M | OID_FDDI_DOWNSTREAM_NODE_LONG The long address of the station below this NIC on the ring |
|
| 4 | M | OID_FDDI_FRAME_ERRORS The number of frames transmitted by this NIC that returned with errors |
|
| 4 | M | OID_FDDI_FRAMES_LOST The number of frames transmitted by this NIC that were not returned within an acceptable interval |
|
| 4 | M | OID_FDDI_RING_MGT_STATE The current state of the ring-management state machine. |
|
| 4 | M | OID_FDDI_LCT_FAILURES The number of times the link confidence test has failed during connection management. |
|
| 4 | M | OID_FDDI_LEM_REJECTS The link error monitor count of the times that a link was rejected. |
|
| 4 | M | OID_FDDI_LCONNECTION_STATE The state of this ports physical connection managment state machine. |
The following describes each of the OID_XXX listed in the preceding chart more fully.

NdisFddiTypeThrough
The long address of the station above this NIC on the ring or zero if the address is unknown.
In a dual-ring configuration, the upstream node is the station from which frames are passed to this station on the primary ring.
The long address of the station below this NIC on the ring or zero if the address is unknown.
In a dual-ring configuration, the downstream node is the station to which frames are passed from this station on the primary ring.
