  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.
