NAME
     smtring - examines the state of FDDI ring

SYNOPSIS
     /usr/etc/smtring [-pdn] [-i interval] [-t timeout] [-I interface] [host]

DESCRIPTION
     smtring is a tool to examine the state of an FDDI ring.  The default is
     to report once either when smtring is interrupted or when it terminates
     after a 60-second timeout.

     The options are:

     -d   Increase the debug level.  Multiple ``d''s increase the level up to
          a maximum of five.

     -p   Passive NIF collection.  With this option, smtring ``passively''
          collects the NIF frames on the FDDI ring.  Without this option, by
          default, smtring collects NIF frames ``actively'' by issuing
          broadcast NIF_REQUEST frames to elicit an NIF_RESPONSE frame from
          FDDI stations and concentrators.

     -n   Numeric output only.  Does not try to translate the MAC address into
          its symbolic name in the ethers database.

     -i interval
          Continually report FDDI neighbor information every interval seconds.

     -I interface
          Examine the state of an FDDI ring in which interface is inserted.
          The interface is a string of the form ``name unit'', for example,
          ``ipg0''.  The default is set to the station's primary interface.

     -t timeout
          Change the default timeout from 60 seconds to timeout seconds.

     host The host can be a FDDI station's MAC address or the symbolic name of
          a FDDI station's  MAC address which can be found in /etc/ethers or
          the NIS ethers.byname map.  The ring status data will be collected
          by host . The default is set to ``localhost''.
