HPUX fddistat[1m]
fddistat(1M) fddistat(1M)
NAME
fddistat - show FDDI interface status
SYNOPSIS
/usr/bin/fddistat [-n] device_file
DESCRIPTION
fddistat displays information about the status of the FDDI interface.
Options and Command-Line Arguments
fddistat recognizes the following options and command-line arguments:
-n Use FDDI native form when displaying address
information. The default is canonical form.
device_file Specifies the device special file associated with
the FDDI interface. By convention, device files
are kept in the /dev directory. Each device file
has a name and a device number to uniquely
identify the interface. See DEPENDENCIES section
of fddiinit(1M) for a description of how to create
device files.
RETURN VALUE
Upon successful completion, fddistat returns 0; otherwise it returns
1.
ERROR MESSAGES
fddistat fails if any of the following conditions is encountered:
o Command used incorrectly - Usage message is returned.
o Invalid device file - returns Can't open device file . Check
the device file. See DEPENDENCIES section of fddiinit(1M) for
a description of how to create device files.
o Hardware or driver error - hardware failed to respond to the
request. Ensure that hardware is correctly connected, and use
the fddiinit command to reinitialize the interface if it is
necessary (see fddiinit(1M)). If the same failure occurs
after the interface is reinitialized, replace the interface
with a known-good unit, if available, then retry the command.
Otherwise, contact your HP Customer Support representative.

Fields are defined as follows:
MAC_Address Medium Access Control (unit) Address. Specifies
the 48-bit MAC Address of the node in hexadecimal
format. The default is canonical form. FDDI
native form is used if the -n option is specified
in the command line.
UNA Upstream Neighbor's (MAC) Address. Specifies the
MAC Address of the upstream neighbor in
hexadecimal format. The default is canonical
form. FDDI native form is used if the -n option
appears in the command line.
RMT Ring Management State. Indicates whether the
state is: Isolated, Non_Op, Ring_Op, Detect,
Non_Op_Dup, Ring_Op_Dup, Directed, or Trace.
Refer to the RMT description in the ANSI FDDI/SMT
specification for more details.
CF_State (Attachment) Configuration State of the station.
Indicates whether the state is: Isolated, Wrap_S,
Wrap_A, Wrap_B, Wrap_AB, or Thru. Only the
Isolated and the Wrap_S states are valid for
single attachment station (SAS). Refer to the
CF_State variable description in the ANSI FDDI/SMT
specification for more details.
Frame_Ct Frame Count. Specifies the total number of frames
received with End Delimiter by the station. This
count includes void frames, token frames, beacon
frames, claim frames, SMT frames and LLC frames.
Receive_Ct Receive Count. Specifies the total number of SMT
or LLC frames successfully received by the
station.
Transmit_Ct Transmit Count. Specifies the total number of
transmit frames originated by this station.
Lost_Ct Lost Count. Specifies the total number of frames
received with format error detected. When the
station detects a frame with a format error, it
strips the rest of the frame from the ring and
replaces it with Idle symbols.

Error_Ct Error Count. Specifies the total number of frames
received with the End Delimiter not set (not 'S').
LER_Estimate Link Error Rate Estimate. Specifies the long term
average link error rate. It ranges from 10**-4
(ten to the -4 power) to 10**-15 (ten to the -15
power).
T_Req Token Request Time. Specifies the requested
Target Token Rotation Time (TTRT) by the local
station in the claim token process. The value of
T_Req is in milliseconds. Refer to the T_Req
value description in the ANSI FDDI/SMT
specification for more details.
T_Neg Negotiated Target Token Rotation Time (TTRT).
Specifies the target rotation time being used by
all the stations on the ring. This value is
negotiated during the claim token process. The
value of T_Neg is in milliseconds. Refer to the
T_Neg value description in the ANSI FDDI/SMT
specification for more details.
