tbDevPollingIntervalThis determine how often the Token Bus Device will be polled for
transmission completion and frame reception. This value is in millisecond.

parameter must be specified in octet time.rw INTEGER ( 0 .. 8191 ) .1.3.6.1.4.1.495.2.1.5.9.2.18 |

frames.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.19 |
tbTxRwrFailuresNumber of transmission failure related to the request with response
frames.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.20 |
tbUnexpectedFrame6sThis counter incrementes when the TBC hears an unexpected frame when
expecting a response to a transmitted request with response frame. An
unexpected frame in this case is any valid frame which is not a response
frame addressed to this station. Upon detecting this event, the TBC
increment this counter and goes to the IDLE without passing the token.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.21 |
tbUnexpectedFrame10sThe TBC module incremented this counter when it executes the 'unexpected
frame 10' transition the IEEE 802.4 access control machine (ACM). It occurs
when the TBC attempted to solicit a new successor and while waiting for a
response, heard either a data frame not sent by itself. When this event
occurs, it indicates a protocol error, possibly a duplicate token situation. After this event,
The TBC will go to the IDLE without passing the token.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.22 |
tbNbUnderrunsThis statistic represents the number of times the TBC detected a FIFO
underrun during transmission.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.23 |
tbRxRetryRwrFramesNumber of detected retransmitted request with response frame. This event
mostly occurs when the RWR frame or its response is lost.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.24 |
tbRxNullLsduRwrFramesNumber of received request with response frame which did not contain any
LLC service data unit (LDSU).ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.25 |
tbNbPassedTokensNumber of time this station thinks it has sucessfully passed the token.
It can be used to calculate the average token rotation time.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.26 |
tbNbHeardTokensNumber of time this station heard a token where Destination Address (DA) or
Source Address (SA) are not equal to This Station (TS) address. This number
can be used to determine how many stations there is on the logical ring.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.27 |
tbNbNoSuccessor8PassesThis statistic indicates the number of times this station has gone through
the no successor 8 arc in the state machine. This happens when the TBC
fails to pass the token and does not succeed in finding a new successor
station. The counter is incremented only if the TBC thinks it is not the
only active station in the network. A significantly large value in this
counter may indicate a 'faulty' transmitter condition in this station.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.28 |
tbNbWhoFollowsFramesThis statistic is the number of times this station has had to look for a
new next station to pass the token to. This frame is sent as part of the
TBC's effort to pass the token to its former successor's successor if the
original successor station does not respond to the token. This counter
is incremented by two every time a failure occurs.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.29 |
tbNbTokenPassFailuresThis statistic indicates the number of token pass failed transitions when
pass state is equal to pass token. Upon failing to pass the token, the
TBC tries to send a second token (pass state equals repeat pass token).
If this effort fails too, this counter is not incremented again; but the
TBC will then send a who follows frame and the who follows query counter
will be incremented.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.30 |
tbRxPeriodNonSilencesThis statistic is the number of received periods of non-silence.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.31 |
tbRxBadCrcFramesThis statistic tracks the number of received frames with FCS (or CRC)
errors and the E-bit reset.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.32 |
tbRxEBitSetFramesThis statistic counts the number of received frames with the E-bit set in
the end delimiter. The E bit, or error bit, is set by the regenerative
repeater (headend remodulator), when the headend detects a FCS error on
the forward channel.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.33 |
tbRxFrameFragmentsThis statistic represents the number of frame fragments (start delimiter
(SD) not followed by a valid end delimiter (ED)). A valid frame consists
of only data (zero or one MAC symbols) between the SD and the ED. If an
SD is detected and then, before a valid ED, the TBC detects either silence,
non data (not part of the aligned ED), or bad signal, then this counter is
incremented. Note that this includes abort sequences.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.34 |
tbRxFrameTooLongsThis statistic is the number of received frames tart are too long
(>8 KBytes).ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.35 |
tbNbNoFdBdErrorsThis statistic counts the number of frames that were not received because
there were not enough frame descriptors or there were not enough buffers.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.36 |
tbNbOverrunsThis statistic represents the number of times the TBC detected a FIFO
overrun during receive.ro Counter .1.3.6.1.4.1.495.2.1.5.9.2.37 |
