WAN-Specific Capabilities of CoNDIS WAN Drivers

  • Article

CoNDIS WAN drivers differ from a non-WAN CoNDIS drivers as follows:

  • CoNDIS WAN drivers that support TAPI services use the CO_ADDRESS_FAMILY_TAPI_PROXY address family.

  • CoNDIS WAN drivers support WAN-specific OIDs: OID_WAN_PERMANENT_ADDRESS, OID_WAN_CURRENT_ADDRESS, and OID_WAN_MEDIUM_SUBTYPE.

  • CoNDIS WAN miniport drivers support a set of CoNDIS WAN OIDs to set and query operating characteristics. For more information about CoNDIS WAN OIDs, see CoNDIS WAN Objects.

  • CoNDIS WAN miniport drivers that provide TAPI services support a set of CoNDIS TAPI OIDs to set and query operating characteristics. For more information about CoNDIS TAPI OIDs, see TAPI Extensions for Connection-Oriented NDIS.

  • CoNDIS WAN miniport drivers support a set of WAN-specific status indications that denote changes in the status of a link. For more information about CoNDIS WAN miniport driver status indications, see Indicating CoNDIS WAN Miniport Driver Status.

  • CoNDIS WAN miniport drivers keep a WAN-specific set of statistics. The OID_WAN_CO_GET_STATS_INFO OID requests the miniport driver to return the statistics information.

  • CoNDIS WAN miniport drivers never attempt to loop back any packets; NDISWAN provides loop-back support.
