MEMBERS

  ctr_name
      Specifies the name of the network interface.

  ctr_type
      Specifies one of the following constants that describes the counter
      type to be accessed by the ioctl request:

      CTR_ETHER
	  Ethernet counters

      CTR_FDDI
	  FDDI counters

      CTR_TRN
	  Token Ring counters

      FDDIMIB_SMT
	  FDDI MIB SMT group

      FDDIMIB_MAC
	  FDDI MIB MAC group

      FDDIMIB_PATH
	  FDDI MIB PATH group

      FDDIMIB_PORT
	  FDDI MIB PORT group

      FDDIMIB_ATTA
	  FDDI MIB attachment group

      FDDI_STATUS
	  FDDI status

      FDDISMT_MIB_SMT
	  FDDI SMT MIB values

      FDDISMT_MIB_MAC
	  FDDI SMT MAC values

      FDDISMT_MIB_PATH
	  FDDI SMT PATH values

      FDDISMT_MIB_PORT
	  FDDI SMT PORT values

      FDDIDECEXT_MIB
	  FDDI legacy DIGITAL-extended MIB values

      CTR_TRN
	  Token Ring counters

      TRN_CHAR
	  Token Ring characteristics

      TRN_MIB_ENTRY
	  Token Ring MIB entry

      TRN_MIB_STAT_ENTRY
	  Token Ring MIB status entry

      FDDIMIB_PORT_B
	  FDDI MIB PORT group

      FDDISMT_MIB_PORT_B
	  FDDI MIB PORT group

  ctr_ctrs
      Specifies the type of counter data stored in the ctrreq data structure.
      This union can contain any one of the following data structures. The
      <if.h> file defines alternate names to make it easier to reference the
      members of the union. For example, it defines an alternate name for the
      Ethernet counter member as follows:


	   #define ctrc_ether ctr_ctrs.ctrc_ether


      _________________________________________________________________
      Structure Type   Alternate Name	Description
      _________________________________________________________________
      estat	       ctr_ether	Ethernet counters
      fstat	       ctr_fddi		FDDI counters
      fddiDNA_status   dna_fddi		FDDI status per DNA spec
      fddismt	       fmib_smt

					FDDI SMT attributes (not
					documented)
      fddimac	       fmib_mac

					FDDI MAC attributes (not
					documented)
      fddiport	       fmib_port

					FDDI PORT attributes (not
					documented)
      fddiatta	       fmib_atta

					FDDI attatch attributes (not
					documented)
      smtmib_smt       smib_smt		SMT MIB attributes
      smtmib_mac       smib_mac		SMT MIB attributes
      smtmib_path      smib_port	SMT MIB attributes
      smtmib_port      smib_path	SMT MIB attributes
      decext_mib       decmib_ext

					Legacy DIGITAL-extended MIB
					(not documented)
      trnchar				Token Ring characteristics
      trncount				Token Ring counters
      dot5Entry				Token Ring MIB counters
      dot5StatsEntry			Token Ring MIB statistics
      _________________________________________________________________








DESCRIPTION

  The SIOCTRDCTRS and SIOCTRDZCTRS ioctl commands use the ctrreq data
  structure to access network counters on behalf of the caller. Although the
  counters differ from one network interface to another, the ctrreq data
  structure can contain any type of counter information. This provides a
  consistent interface for the ioctl system call.
