1 – Characteristics
o link address MAC address assigned during manufacture of the communication hardware that is associated with the station (read-only). o requested trt Default: 8.0 Value: 1-65535 Requested token rotation timer. o restricted token timeout Default: 1000 Value: 1-65535 Length limit of a restricted token dialog. o ring purger enable Default: True Value: True or false Controls whether this station is eligible to be a ring purger and should participate in the ring purger election. o valid transmission time Default: 3.4 Value: 1-65535 Valid transmission time.
2 – Counters
o block check errors Number of times a received frame containing an integral number of octets failed the FCS check. o creation time Time at which the station was created. o directed beacons received Number of times the link detected the directed beacon process. o duplicate address test failures Number of times the duplicate address test failed (detected that the link address was a duplicate). o duplicate tokens detected Number of times the MAC address test failed (detected that the link address was a duplicate). o error count Total number of frames that were in error with the E indicator reset, indicating that the error occurred between the upstream MAC and this one. o fci strip errors Number of times a frame content independent strip operation (bridge strip) was terminated by receipt of a token. o frame count Total number of frames seen by this link, other than tokens. o frame status errors Number of times a received frame had the E indicator in error (missing or set) and the FCS was correct. o lost count Counter lost count. o multicast octets received Number of multicast data octets that were successfully received in multicast frames of type LLC, implementer, reserved, or SMT. The count does not include the MAC envelope. o multicast octets sent Number of multicast data octets that were successfully sent in multicast frames of type LLC, implementer, reserved, or SMT. The count does not include the MAC envelope. o multicast pdus received Number of multicast frames that were successfully received of type LLC, implementer, reserved, or SMT. o multicast pdus sent Number of multicast frames that were successfully sent of type LLC, implementer, reserved, or SMT. o octets received Number of octets successfully received in frames of type LLC, implementer, reserved, or SMT. The count does not include the MAC envelope. o octets sent Number of octets successfully sent in frames of type LLC, implementer, reserved, or SMT. The count does not include the MAC envelope. o pdu length errors Number of times a received frame had an invalid length, either too long or short for the type, or had an alignment error (odd number of symbols). o pdus received Number of frames successfully received in frames of type LLC, implementer, reserved, or SMT. o pdus sent Number of frames successfully sent in frames of type LLC, implementer, reserved, or SMT. o receive data overruns Number of times the hardware lost one or more consecutive, only partially complete incoming frames because it was unable to keep up with the medium rate. An example is overrun of a bit or octet FIFO queue because of inability to copy data from adapter to host promptly. In conjunction with total frames received, provides a measure of hardware resource and bandwidth failures. o ring beacons initiated Number of times the ring beacon process was initiated by this link. o ring initializations initiated Number of times a ring reinitialization was initiated by this link. o ring initializations received Number of times a ring reinitialization was initiated by some other link. o ring purge errors Number of times the ring purger received a token while still in the ring purge state. o token count Number of times a token has been seen by this link. o transmit underruns Number of times a transmit underrun occurred. This indicates the transmit FIFO became empty during frame transmission. o traces initiated Number of times the pc trace process was initiated by this link. o transmit failures Number of times a transmit error, other than underrun, occurred. This does not include errors in transmitting MAC type frames. o unavailable link buffers Number of times a complete, fully received frame was discarded because no link buffer was available. In conjunction with total frames received, provides a measure of station-buffer-related receive problems. o unavailable user buffers Number of times no user buffer was available for an incoming frame that passed all filtering for the port. These are the buffers supplied by users on receive requests. In conjunction with total frames received, provides a measure of user-buffer- related receive problems. o unrecognized individual destination pdus Number of times a received LLC frame with an individual destination MAC address was discarded because there was no port with the Ethernet protocol type, SNAP protocol identifier, or LLC SAP address enabled. Only frames containing individual destination MAC addresses are counted. o unrecognized multicast destination pdus Number of times a received LLC frame with a multicast destination MAC address was discarded because there was no port with the Ethernet protocol type, SNAP protocol identifier, or LLC SAP address enabled. Only frames containing multicast destination MAC addresses are counted.
3 – Identifier
o index An integer that uniquely identifies this link to the parent station entity.
4 – Status
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.
