General statistics OIDs for connection-oriented miniport drivers
The following table summarizes the OIDs used to get or set the general statistics characteristics of connection-oriented miniport drivers and/or their NICs.
Tip
A connection-oriented miniport driver handles such requests in its MiniportCoOidRequest callback function.
In this table, M indicates an OID is mandatory, while O indicates it is optional.
| Length | Query | Set | Name |
|---|---|---|---|
| 4 or 8 | O | OID_GEN_CO_BYTES_RCV | |
| 4 or 8 | O | OID_GEN_CO_BYTES_XMIT | |
| 4 or 8 | O | OID_GEN_CO_BYTES_XMIT_OUTSTANDING | |
| 4 or 8 | O | OID_GEN_CO_NETCARD_LOAD | |
| 4 or 8 | O | OID_GEN_CO_RCV_CRC_ERROR | |
| 4 or 8 | M | OID_GEN_CO_RCV_PDUS_ERROR | |
| 4 or 8 | M | OID_GEN_CO_RCV_PDUS_NO_BUFFER | |
| 4 or 8 | M | OID_GEN_CO_RCV_PDUS_OK | |
| 4 or 8 | O | OID_GEN_CO_TRANSMIT_QUEUE_LENGTH | |
| 4 or 8 | M | OID_GEN_CO_XMIT_PDUS_ERROR | |
| 4 or 8 | M | OID_GEN_CO_XMIT_PDUS_OK |
Miniport driver support for 64-bit counters
All one-Gbps and faster connection-oriented miniport drivers must support 64-bit counters for the following statistics OIDs. In addition, Microsoft recommends that all 100Mbps and faster connection-oriented miiniport drivers support 64-bit counters for the following statistics OIDs:
Such miniport drivers can also support 64-bit counters for other statistics OIDs, such as OIDs that indicate transmit or receive errors.
System support for 64-bit counters is available in Windows XP and later versions.
