____________________________________
MEMBERS
trn_second
Specifies the number of seconds since the structure was last zeroed.
trn_bytercvd
Specifies the number of bytes that were successfully received.
trn_bytesent
Specifies the number of bytes that were transmitted.
trn_pdurcvd
Specifies the number of frames that were successfully received.
trn_pdusent
Specifies the number of frames that were transmitted.
trn_mbytercvd
Specifies the number of multicast bytes that were successfully
received.
trn_mpdurcvd
Specifies the number of multicast frames that were successfully
received.
trn_mbytesent
Specifies the number of multicast bytes that were transmitted.
trn_mpdusent
Specifies the number of multicast frames that were transmitted.
trn_pduunrecog
Specifies the number of times that a frame was discarded because there
was no data link port with a matching Token Ring protocol type, LLC,
SAP, or SNAP protocol ID.
trn_mpduunrecog
Specifies the number of multicast frames that were discarded.
trn_nosysbuf
Specifies the number of times that a frame was discarded because no
link buffer was available. This counter measures the number of frames
discarded before the data link user that wants the frame has been
identified by frame filtering.
trn_xmit_fail
Specifies the number of times that a transmit error other than an
underrun has occurred.
trn_xmit_underrun
Specifies the number of times that a transmit underrun error has
occurred. This indicates that the transmit FIFO became empty during
frame transmission.
trn_line_error
Specifies the number of times that either of the following conditions
has been detected:
·
A frame or token is copied or repeated by a station.
·
The E bit is 0 (zero) in the frame or token, and one of the following
conditions exists:
--
There is a nondata bit (J or K bit) between the SD and the ED of
the frame or token.
--
There is an FCS error in the frame.
trn_internal_error
Specifies the number of recoverable internal errors that have occurred.
trn_burst_error
Specifies the number of times that the station has detected the absence
of transitions for five half-bit timers or burst-five errors.
trn_ari_fci_error
Specifies the number of times that the upstream neighbor could not set
the ARI or FCI bits of received frames.
trn_ad_trans
Specifies the number of abort delimiters that have been transmitted.
trn_lost_frame_error
Specifies the number of times that the station's TRR timer has expired
during a transmit operation. This counter can indicate when a
transmitting station in strip mode does not receive the trailer of the
frame before the TRR timer goes off.
trn_rcv_congestion_error
Specifies the number of times the station has recognized a frame
addressed to its address, but has no available buffer space. This
counter can indicate when the station is congested.
trn_frame_copied_error
Specifies the number of times that the station has recognized a frame
addressed to its address and detects that the FS field A bits are set
to 1. This counter can indicate a line hit or duplicate address.
trn_frequency_error
Specifies the number of frequency errors that have occurred.
trn_token_error
Specifies the number of times that the station, acting as the active
monitor, has recognized an error condition that needs a token
transmitted.
trn_hard_error
Specifies the number of times that the station has detected an
immediately recoverable fatal error. It denotes the number of times
this interface is either transmitting or receiving beacon MAC frames.
trn_soft_error
Specifies the number of soft errors that the station has detected. It
directly corresponds to the number of report error MAC frames that this
station has transmitted. Soft errors are recoverable by the MAC layer
protocols.
trn_adapter_reset
Specifies the number of resets that have been performed on this
station.
trn_signal_loss
Specifies the number of times that the station has detected the loss of
a signal condition from the ring.
trn_xmit_beacon
Specifies the number of times that the station has transmitted a beacon
frame.
trn_ring_recovery
Specifies the number of claim token MAC frames received or transmitted
after the station has received a ring purge MAC frame. This counter
signifies the number of times the ring has been purged and is being
recovered into a normal operating state.
trn_lobe_wire_fault
Specifies the number of times that the station has detected an open or
short circuit in the lobe data path. When this occurs, the adapter is
closed and the dot5RingState member of the dot5Entry structure is set
to MIB1231_RSTAT_CLOSED.
trn_remove_received
Specifies the number of times that the station has received a remove
ring station MAC frame request. When this frame is received, the
station enters the closed state and the driver sets the dot5RingState
member of the dot5Entry structure to MIB1231_RSTAT_CLOSED.
trn_single_station
Specifies the number of times that the host has recognized that it is
the only station on the ring.
trn_selftest_fail
Specifies the number of times that the station has sensed that it is
the only station on the ring. This happens when the station is the
first one up on a ring or when a hardware problem exists.
DESCRIPTION
The trncount data structure defines Token Ring counters. It is embedded
within a ctrreq data structure when the driver supports the Token Ring
network interface. The SIOCRDCTRS and SIOCRDZCTRS ioctl commands initialize
this data structure and return it to the user process that made the ioctl
request.
