NAME

fddinet − display logical FDDI ring map information

SYNOPSIS

/usr/bin/fddinet [-n] [-d station_address] device_file

DESCRIPTION

fddinet displays logical connection information for the reachable nodes connected to the same FDDI ring. 

Options and Command-Line Arguments

fddinet recognizes the following options and command-line arguments:

-n Use FDDI native form when displaying address information.  The default is the canonical form. 

-d station_address
Specifies the MAC Address of the node that is to be first in the display of the logical ring map.  If the -n option is used in the command line, the MAC Address is a 12-character, hexadecimal-digit string in FDDI native form; otherwise, the default canonical form is used.  It can start with or without the usual 0x prefix.  For example, both 0x080009091219 and 080009091219 are valid MAC Addresses. 

device_file 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 the DEPENDENCIES section of fddiinit(1M) for a description of how to create device files.

RETURN VALUE

Upon successful completion, fddinet returns 0; otherwise it returns 1. 

ERROR MESSAGES

fddinet 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 the hardware is correctly connected, then use fddiinit to reinitialize the interface if necessary (see fddiinit(1M)). If the same failure happens after interface reinitialization, replace the interface with a known-good unit, if one is available, and retry the command. Otherwise, contact your HP Customer Support representative.

EXAMPLE OUTPUT

Fields are defined as follows:

MAC_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 appears in the command line. 

Node_Type Specifies whether the node is a Single Attachment Station (SAS), Dual Attachment Station (DAS), or Concentrator.  SAS and DAS station types include the MAC count displayed inside parentheses after the node type; concentrator station types include the number of master ports inside parentheses after the node type. 

UNA 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. 

Topology Displays the topology of the station.  Possible values are:

Wrapped Set when the station’s attachment state is Wrap_A, Wrap_B, Wrap_S, or Wrap_AB. 

Unrooted Set when a concentrator has no active A, B or S Port. 

Twisted A-A Set when an A-A connection is detected in the station. 

Twisted B-B Set when a B-B connection is detected in the station. 

Rooted Set when the station does not have an A or B or S Port active in tree mode. 

SRF Set if the station supports the Status Report (SRF) protocol.
