NAME
     fddivis - graphically display FDDI ring

SYNOPSIS
     fddivis [-c ConfFile] [-r RecDir] [host]

DESCRIPTION
     fddivis provides a graphical display the state of the FDDI ring.  It
     forms a map of an FDDI ring as it watches Station Management (SMT)
     Neighborhood Information Frame (NIF), Station Information Frame (SIF),
     and Status Report Frame (SRF) traffic.  It is a full-screen application
     consisting of three windows: Ring, Map, and Control Panel.  The largest
     of these, the Ring window, displays a representation of the ring.  The
     Map window provides a summary of the ring map and is used to control the
     position of the ring in the Ring window. The Control Panel window is used
     to change what is displayed and the type of information collected.

     Operating parameters are kept in F1$HOME/.fddivisrc, but -c can be used
     to specify an alternate file.  -r can be used to start recording
     snapshots of the state of the ring as the program starts.

     The host to which the ring is connected can be specified with the host
     argument.  This is particularly useful for monitoring a ring that is
     connected to a remote system.  While fddivis can be run remotely and
     display its pictures using the usual remote graphics facilities, running
     it locally but obtaining data remotely requires much less network
     bandwidth.  It is entirely practical to monitor a remote FDDI ring over a
     very low speed network connection such as a SLIP or PPP link using the
     host facility.

   Ring Window
     The main window of fddivis shows the ring using icons for stations (and
     concentrators) connected by lines.  The MAC address(es) for the stations
     are also shown.  Neighboring stations that are reachable are shown with
     white solid lines.  The portion of ring that is broken is shown with a
     red broken line.  Twists in the ring are shown with crossed lines.  By
     default the IRIS is presented at the top of the ring as a workstation
     with a purple screen.  The number of icons displayed is controlled by the
     Partial/Full button in the Control Panel.  In the fullscreen mode, all
     the icons are displayed at the same time.  When there are many stations
     on the ring, it may be hard to distinguish an individual icon and its MAC
     address.  In partial mode, at most 5 or 6 icons are displayed.  (If there
     are less than 10 stations on the ring, they are all displayed.)  The
     portion of ring to be drawn on the Ring window can be selected by
     dragging or clicking the selecting arm in the Map Window at the upper-
     left corner of the screen.  Clicking the left mouse button on a station
     creates a window that displays detailed configuration and operational
     information about the station.  Clicking the middle mouse button on a
     station creates a window that contains a remote login session to the
     station's ``guest'' account.
   Map Window
     The Map window shows an overall view of the FDDI ring.  Each station is
     represented by a small filled-in circle.  The purple circle at top of the
     ring represents the IRIS.  Light-blue circles show the position of the
     known neighbors within the FDDI ring, and gray circles show the position
     of neighbors that are physically known but logically unknown.

     When in partial mode, the red arm in this window  controls what view is
     displayed in the Ring window.  While the cursor is in the Map window,
     press and hold down and drag or just click the left mouse button to move
     the red arm.

   Control Panel
     The Control Panel is a mouse-driven menu.  To change or select an item,
     simply move the arrow cursor over the item, and click the left mouse
     button.  There are four subpanels - Display, Capture, Tutorial, and
     Status - that are selected via the four large buttons at the bottom of
     the Control Panel.  An overview of each of the main control panel items
     follows:

     Display
          Collect and display NIF, SIF, and SRF information in real time.
     Capture
          Control type of NIF, SIF, and SRF information and the query interval.
     Tutorial
          Show the capabilities of fddivis.
     Status
          Monitor the operational SMT parameters of the ring.
