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.
