o downstream neighbor MAC address of the downstream neighbor, if known. o duplicate address flag Summary output of the duplicate address test algorithm. o 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 The FCIS mode counts the number of frames transmitted strip since the reception of a token, and strips equal number of frames. o 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. o negotiated trt Negotiated token rotation timer. o old downstream neighbor Previous value of the downstream neighbor. o old upstream neighbor Previous value of the upstream neighbor. o ring error reason Reason code for the most recent link error. duplicate Duplicate address algorithm detected a duplicate address address. detected duplicate A duplicate token was detected on the ring. token detected no error No errors have occurred on this ring. ring init Ring initialization was initiated by this link to initiated initialize the ring and create a token. ring init Ring initialization was initiated by some other received link to initialize the ring and create a token. ring Ring beaconing process was initiated by this link. beaconing This process in initiated as a result of serious initiated 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 purge Link received a token while performing a ring error purge operation. FCI strip Frame content independent strip operation was error terminated by the receipt of a token. ring op Ring state has been continually changing from oscillation operational to initializing. directed Link received particular beacon data. beacon received PC trace PC-trace was initiated by this link. initiated PC trace PC-trace was initiated by some other link. received o ring latency Current ring latency as measured by this link entity. o 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. o 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. off-fault State entered when a link entity detects recovery conditions that indicate faulty ring. 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. o uid Entity's unique identifier, which is generated when the entity is created. o upstream neighbor MAC address of the upstream neighbor, if known. o upstream neighbor duplicate address flag Default: false Value: True or false Upstream neighbor's reported result of its duplicate address test.
