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:

• 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.

EXAMPLE OUTPUT

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. 

Multicast addresses configured
Shows the list of multicast addresses configured on this node. Packets received with one of these multicast addresses will be accepted, others will be dropped.
