This describes the OIDs for Token Ring objects, both operational and statistical types.
Token Ring Operational Characteristics
The following chart summarizes the OIDs used to get or set Token Ring operational characteristics for NDIS drivers and NICs.
| Length | Q | S | Name |
| 6 | M | OID_802_5_PERMANENT_ADDRESS Permanent station address |
|
| 6 | M | OID_802_5_CURRENT_ADDRESS Current station address |
|
| 4 | M | M | OID_802_5_CURRENT_FUNCTIONAL Current functional address |
| 4 | M | M | OID_802_5_CURRENT_GROUP Current group address |
| 4 | M | OID_802_5_LAST_OPEN_STATUS Last open status |
|
| 4 | M | OID_802_5_CURRENT_RING_STATUS Current ring status |
|
| 4 | M | OID_802_5_CURRENT_RING_STATE Current ring state |
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 library. It must set the address as a configuration parameter.
The functional address enabled on the NIC for packet reception.
When the underlying driver initializes its NIC, it resets the functional address to zero. NDIS also initializes the packet filter so that a protocol does not receive functional address packets.
To receive a functional address packet, a bound protocol must later set the packet filter to include the NDIS_PACKET_TYPE_FUNCTIONAL flag. At any time, it can disable packet reception by canceling this flag. The order in which the protocol enables reception for functional address packets is unimportant.
The group address enabled on the NIC for packet reception.
The last open error status returned for a protocol's call to NdisOpenAdapter.
If the open succeeded, a status code other than NDIS_STATUS_OPEN_FAILED was returned for the most recent open of the target NIC, so the value returned for this query should be zero.
The last ring status indicated with an NDIS_RING_XXX status code, which can be any of the following values:
NDIS_RING_SIGNAL_LOSS
NDIS_RING_HARD_ERROR
NDIS_RING_SOFT_ERROR
NDIS_RING_TRANSMIT_BEACON
NDIS_RING_LOBE_WIRE_FAULT
NDIS_RING_AUTO_REMOVAL_ERROR
NDIS_RING_REMOVE_RECEIVED
NDIS_RING_COUNTER_OVERFLOW
NDIS_RING_SINGLE_STATION
NDIS_RING_RING_RECOVERY
The state of the NIC driver with respect to entering the ring, as one of the following:
NdisRingStateOpened
Specifies an open ring.
NdisRingStateClosed
Specifies a closed ring.
NdisRingStateOpening
Specifies a ring that is opening.
NdisRingStateClosing
Specifies a ring that is closing.
NdisRingStateOpenFailure
Specifies a failure of a ring open operation.
NdisRingStateRingFailure
Specifies a failure of the ring.
Token Ring Statistics
The following chart summarizes the OIDs used to get Token Ring statistics for NICs.
| Length | Q | S | Name |
| 4 | M | OID_802_5_LINE_ERRORS FCS or code violations detected in repeated frame |
|
| 4 | M | OID_802_5_LOST_FRAMES Frames transmitted that have failed to return |
|
| 4 | O | OID_802_5_BURST_ERRORS Number of five half-bit transition absences detected |
|
| 4 | O | OID_802_5_AC_ERRORS Access control (A/C) errors |
|
| 4 | O | OID_802_5_ABORT_DELIMITERS Frames transmitted with abort delimiter |
|
| 4 | O | OID_802_5_FRAME_COPIED_ERRORS Frame copy errors |
|
| 4 | O | OID_802_5_FREQUENCY_ERRORS Frequency errors detected |
|
| 4 | O | OID_802_5_TOKEN_ERRORS Active monitor regenerations |
|
| 4 | O | OID_802_5_INTERNAL_ERRORS Internal errors detected |
The following describes each of the OID_XXX listed in the preceding chart more fully.
The number of frames with an invalid FCS or a code violation.
The number of frames transmitted that have not circled the ring within the maximum ring latency.
The number of frames containing five half bits with no transition.
The number of frames with A/C errors.
The number of abort delimiters transmitted.
The number of frames addressed to this NIC that another NIC on the ring has also copied.
The number of frequency errors on the ring.
The number of times the NIC has been the active monitor and has had to recreate.
The number of internal errors the NIC has detected.
