DOWNSTREAM NEIGHBOR

         MAC address of the downstream neighbor, if known.

     DUPLICATE ADDRESS FLAG

         Summary output of the duplicate address test algorithm.

     FRAME STRIP MODE

         Current frame stripping mode of the MAC.

         SA MATCH -  Source address match mode of the frame stripping
                     algorithm matches the source address of the frame
                     with the MAC's MyLongAddress MLA, and if a match
                     is found, the frame is removed from the token ring.

         FCI STRIP - The FCIS mode counts the number of frames
                     transmitted since the reception of a token, and
                     strips equal number of frames.

     LOOPBACK

         This is true if the link has been set up to receive frames
         transmitted  by it.  This allows loopback testing either on the
         ring or with one of the PHY port loopback modes.

     NEGOTIATED TRT

         Negotiated token rotation timer.

     OLD DOWNSTREAM NEIGHBOR

         Previous value of the downstream neighbor.

     OLD UPSTREAM NEIGHBOR

         Previous value of the upstream neighbor.

     RING ERROR REASON

         Reason code for the most recent link error.

        DIRECTED BEACON RECEIVED -   Link received particular beacon data.

        DUPLICATE ADDRESS DETECTED - Duplicate address algorithm detected a
                                     duplicate address.

        DUPLICATE TOKEN DETECTED -   A duplicate token was detected on the
                                     ring.

        FCI STRIP ERROR -            Frame content independent strip
                                     operation was terminated by the
                                     receipt of a token.

        NO ERROR -                   No errors have occurred on this ring.

        PC TRACE INITIATED -         PC-trace was initiated by this link.

        PC TRACE RECEIVED -          PC-trace was initiated by some other
                                     link.

        RING BEACONING INITIATED -   Ring beaconing process was initiated by
                                     this link. This process in initiated as
                                     a result of serious ring failure, such
                                     as loss of signal or jabbering station
                                     transmitting in violation of the
                                     protocol.  This indicates to other
                                     links on the LAN that corrective action
                                     may be required.

        RING INIT INITIATED -        Ring initialization was initiated by
                                     this link to initialize the ring and
                                     create a token.

        RING INIT RECEIVED -         Ring initialization was initiated by
                                     some other link to initialize the ring
                                     and create a token.

        RING OP OSCILLATION -        Ring state has been continually changing
                                     from operational to initializing.

        RING PURGE ERROR -           Link received a token while performing a
                                     ring purge operation.

     RING LATENCY

         Current ring latency as measured by this link entity.

     RING PURGER STATE

         State of the ring purger election process.

         CANDIDATE - The Link's Ring Purger process is participating in the
                     Ring Purger election algorithm as a candidate to become
                     the Ring Purger.

         NONPURGER - The Link's Ring Purger process is in an idle state
                     listening for periodic Purger Hello frames.

         OFF -       The Link's Ring Purger process is disabled.

         PURGER -    The Link's Ring Purger process is performing the
                     function of removing no owner frames and duplicate
                     token from the ring.  In this state, the process
                     transmits periodic Purger Hello frames.

     STATE

         State of the link entity.

         BROKEN -             Attempt to turn the link on failed the
                              initialization test, or link was on, but
                              failure was detected.

         OFF-READY -          FDDI Data Link communication services are not
                              available.

         ON-RING INIT -       Physical layer service is available and the
                              link entity enabled.

         ON-RING RUN -        Link detected that the Ring Initialization has
                              been successfully completed and the ring is
                              operational.

         OFF-FAULT RECOVERY - State entered when a link entity detects
                              conditions that indicate faulty ring.

     UPSTREAM NEIGHBOR ADDRESS

         MAC address of the upstream neighbor, if known.

     UPSTREAM NEIGHBOR DUPLICATE ADDRESS FLAG

         Upstream neighbor's reported result of its duplicate address test.
