Members

  • wszName
    Pointer to a Unicode string that contains the name of the interface.
  • dwIndex
    The index that identifies the interface.
  • dwType
    The type of interface.
  • dwMtu
    The maximum transmission unit (MTU) of the underlying hardware.
  • dwSpeed
    The speed of the interface in bits per second.
  • dwPhysAddrLen
    The length of the physical address specified by the bPhysAddr member.
  • bPhysAddr
    The physical address of the adapter for this interface.
  • dwAdminStatus**
    The interface is administratively enabled or disabled.
  • dwOperStatus**
    The operational status of the interface. The following table shows the possible values for this member.
    Value Meaning
    MIB_IF_OPER_STATUS_NON_OPERATIONAL LAN adapter has been disabled, for example because of an address conflict.
    MIB_IF_OPER_STATUS_UNREACHABLE WAN adapter that is not connected.
    MIB_IF_OPER_STATUS_DISCONNECTED For LAN adapters: network cable disconnected. For WAN adapters: no carrier.
    MIB_IF_OPER_STATUS_CONNECTING WAN adapter that is in the process of connecting.
    MIB_IF_OPER_STATUS_CONNECTED WAN adapter that is connected to a remote peer.
    MIB_IF_OPER_STATUS_OPERATIONAL Default status for LAN adapters.
  • dwLastChange
    The last time the operational status changed.
  • dwInOctets
    The number of octets of data received through this interface.
  • dwInUcastPkts
    The number of unicast packets received through this interface.
  • dwInNUcastPkts
    The number of non-unicast packets received through this interface. This includes broadcast and multicast packets.
  • dwInDiscards
    The number of incoming packets that were discarded even though they did not have errors.
  • dwInErrors
    The number of incoming packets that were discarded because of errors.
  • dwInUnknownProtos
    The number of incoming packets that were discarded because the protocol was unknown.
  • dwOutOctets
    The number of octets of data sent through this interface. Number of octets equals number of bytes.
  • dwOutUcastPkts
    The number of unicast packets sent through this interface.
  • dwOutNUcastPkts
    The number of non-unicast packets sent through this interface. This includes broadcast and multicast packets.
  • dwOutDiscards
    The number of outgoing packets that were discarded even though they did not have errors.
  • dwOutErrors
    The number of outgoing packets that were discarded because of errors.
  • dwOutQLen**
    The output queue length.
  • dwDescrLen**
    The length of the bDescr member.
  • bDescr
    Contains a description of the interface.
