NAME

fddiconfig − FDDI interface parameter setting and display

SYNOPSIS

fddiconfig interface [ configfile ]

DESCRIPTION

fddiconfig sets the parameters listed in configfile for the interface. If no configfile is specified, the current interface settings and the station status are displayed.  To change setting values, first update configfile and then run fddiconfig.  Interface must be either fn0 or fn1.  fn2 and fn3 are also possible on NWS-5000/5900.  Any name may be used for configfile.  Each line of configfile contains a parameter identifier and a setting value, separated by spaces or tabs.  The parameter identifier should be at the beginning of the line.  The character “#” and any characters that follow are considered comments.  The settable parameters are T_Req, UserData, Multi, Threshold and Verbose. 
T_Req is a requested TTRT (Target Token-Rotation Timer) value. When a ring is built, this value is exchanged together by all of the stations and concentrators on the ring, and the lowest value determines the T_Neg (Negotiated TTRT) value. If T_Req is changed, the TTRT value is reinitialized.
UserData is a string of user-defined ASCII characters up to 31 characters long. NEWS uses this as ECHO frame data.
Multi is a flag to determine either multi-frame per token mode(1) or single-frame per token mode(0). This is possible on NWS-5000/5900.
Threshold is a variable to determine Transmit FIFO threshold. That is determined by amount of data in FIFO. This is possible on NWS-5000/5900.
Verbose is a flag to determine whether print verbose information(1) or not(0) when FIFO underrun occurred. This is possible on NWS-5000/5900.
For those parameter, refer to /usr/sony/etc/{fddi.conf0,fddi.conf1}.

NOTES

Parameter settings must be performed by super user only.  Fddiconfig may not be used on the same interface on which fddimap is running.
