nvoElapsedTime (
SNVT_elapsed_tm
): Time since device powered up or since the
statistics for this port where reset. The statistics can be reset with the network variable
nviClearStat
in the node object (see Section 13.2.2) or if the node is reset with a
network management command (e.g., while the device is commissioned). If the
monitored port is not available in a system configuration, the value is set to the invalid
value. The NV is polled only.
nvoAvgPkts (SNVT_count_32): The average number of packets per second received or
transmitted via the associated channel since power-up or since the statistics for this port
where reset.
nvoIvalBandUtl (
SNVT_lev_cont
): Bandwidth utilization of associated channel during
the last interval. For a smooth operation of the CEA-709 segment, the average
bandwidth utilization must remain below 50 %.
nvoIvalCrcErr (
SNVT_lev_cont
): Percentage of packets with CRC error received on the
associated channel during the last interval.
nvoIvalMissed (
SNVT_lev_cont
): Percentage of packets from the associated channel
which could not be processed during the last interval.
nvoIvalPkts (
SNVT_count_32
): Number of packets received or transmitted via the
associated channel during the last interval.
nvoTotalCrcErr (
SNVT_count_32
): Total number of packets with CRC error received
via the associated channel since power-up or since the statistics for this port where
reset.
nvoTotalMissed (
SNVT_count_32
): Total number of packets from the associated
channel which could not be processed since power-up or since the statistics for this port
where reset.
nvoTotalPkts (
SNVT_count_32
): Total number of packets received or transmitted via
the associated channel since power-up or since the statistics for this port where reset.
nvoMaxBandUtl (
SNVT_lev_cont
): Maximum value of
nvoIvalBandUtl
since power-up
or since the statistics for this port where reset. For a smooth operation of the CEA-709
segment the average bandwidth utilization must remain below 50 %.
nvoMaxCrcErr (
SNVT_lev_cont
): Maximum value of
nvoIvalCrcErr
since power-up or
since the statistics for this port where reset.
nvoMaxMissed (
SNVT_lev_cont
): Maximum value of
nvoIvalMissed
since power-up or
since the statistics for this port where reset.
nvoMaxPkts (
SNVT_count_32
): Maximum value of
nvoIvalPkts
since power-up or
since the statistics for this port where reset.
nvoIvalMisPre (
SNVT_count_32
): Number of missed preambles per second on the
associated channel measured during the last interval. A missed preamble is detected
whenever the link layer receives a preamble which is shorter then the defined preamble
length. A large number in this counter is usually due to noise on the channel.
nvoTotalMisPre (
SNVT_count_32
): Total number of missed preambles per second on
the associated channel measured since power-up or since the statistics for this port
where reset.
nvoMaxMisPre (
SNVT_count_32
): Maximum value of
nvoIvalMisPre
since power-up
or since the statistics for this port where reset.
nvoChnlAlarm (
SNVT_switch
): Signals an overload alarm condition of the channel
during the last statistic interval. A channel can be overloaded due to one of the
following conditions:
o
The bandwidth utilization during the last statistic interval (
nvoIvalBandUtl
)
exceeded the limit defined by the
SCPThighLimit1
(default 70 %) OR
