NAME
fddistat — show FDDI interface status
SYNOPSIS
/usr/sbin/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.
ERRORS
fddistat
fails if any of the following conditions is encountered:
Command used incorrectly - Usage message is returned.
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.
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.
EXAMPLES
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
to
10-15.
- 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.
