niffconfig(8)
NAME
  niffconfig - Configuration program for the Network Interface Failure Finder
  (NIFF)

SYNOPSIS
  /usr/sbin/niffconfig [-a] [-m] [-r] [-s] [-u] [-v] [-d num] [-o num] [-t
  num] [interface1 interface2...]

OPTIONS
  -a  Adds an interface or interfaces, specified by the interface parameter.
      You cannot specify the -a option with the -m, -s, -r, or -u options.

  -d num
      Specifies the time period, in seconds, that the traffic monitor thread
      uses between reads of the interface counters when it suspects there is
      a connectivity problem. This number must be smaller than the number
      given for the -t option. The default time period is 5 seconds. If num
      is not specified, niffconfig uses the default.

  -o num
      Specifies the total number of traffic-free seconds that must elapse
      before the traffic monitor thread determines that a network interface
      has failed.  This number must be at least the sum of the -d option and
      two times the -t option.	That is, given the default time period for -d
      and -t, the -o option must be at least 20 seconds.  The default time
      period for this option is 60 seconds. If num is not specified,
      niffconfig uses the default.

  -m  Modifies the timing parameters of an interface that is already being
      monitored. Typically, this option is specified along with one or more
      of -t num, -d num, or -o num options.  If none of these parameters are
      specified, the default value is used. You cannot specify the -m option
      with the -a, -s, -r, or -u options.

  -r  Stops monitoring the specified interface.

  -s  Obtains the status of the specified interface.

  -t num
      Specifies the time period, in seconds, that the traffic monitor thread
      delays between reads of the interface counters when the network is
      running normally.	 The default time period is 20 seconds. If num is not
      specified, niffconfig uses the default.

  -u  Displays the status of all interfaces currently being monitored to
      standard out (stdout).

  -v  Displays the status, timer values, and description (verbose mode) of
      all interfaces currently being monitored to standard out (stdout).


DESCRIPTION
  The niffconfig command arranges for one or more network interfaces to be
  monitored for possible loss of connectivity.	Timing parameters that govern
  how quickly an interface can be declared suspect or dead may be manipulated
  with this command. You can specify multiple interfaces, separated by a
  space, on the command line. Note, you must be superuser to use the
  niffconfig command.

  Except for the -u and -u options, all niffconfig options require one or
  more network interfaces to be specified.

EXAMPLES
   1.  To add the tu0 and tu1 interfaces to the list of monitored interfaces,
       enter:
	    # niffconfig -a tu0 tu1

   2.  To change the time it takes to declare failure on the tu1 interface to
       90 seconds, enter:
	    # niffconfig -o 90 tu1

   3.  To display the status of all interfaces that are being monitored:
	    # niffconfig -u

   4.  To stop monitoring the tu0 interface:
	    # niffconfig -r tu0
