Logging - System
TIMESYNC_ N _AVG_DELAY= Logs the current network delay time between the
card and the clock sending the synchronization
messages. This should be relatively constant and is
dependent on network configuration.
TIMESYNC_ N _STDV_DELAY= Logs the current standard deviation in the network
delay time between the card and the clock sending
the synchronization messages. Should be a low
number as the network delay is expected to be
constant.
TIMESYNC_ N _AVG_ERROR= Logs the current difference between the cards time
and the grandmaster time. Should be close to zero
once card has synchronized.
TIMESYNC_ N _STDV_ERROR= Logs the standard deviation in the average error.
TIMESYNC_ N _GRANDMASTER= Logs the identity of network clock acting as PTP
grandmaster. This is the source of the PTP
synchronization messages used by all PTP slave
clocks on the network. If there are multiple
grandmasters, they should negotiate between
themselves to identify the most accurate and then
silence the others.
TIMESYNC_ N _LAST_LOCK= Logs the time when the card last changed from not
locked to locked. Ideally this will be a few seconds
after the card has powered up. This allows you to
confirm which clock the card has synchronized to.
TIMESYNC_ N _SYNCHRONISATION
S=
Logs the number of times the card has synchronized
since it was powered up. Ideally this will be a low
number, as cards are expected to synchronize and
stay synchronized. Large numbers indicate possible
problems with the network or grandmaster clock.
TIMESYNC_N_STATE=
When
card is synchronized to a network PTP
grandmaster clock, this shows the connection state:
OK
or
FAIL
TIMESYNC_N_CLOCK_ADDRESS=
When
card is synchronized to a network PTP
grandmaster clock, this shows the
PTP grandmaster
clock’s IP address.
TIMESYNC_N_REQUEST_INTERVAL
=
When
card is synchronized to a network PTP
grandmaster clock, this shows the
interval between
PTP message.
TIMESYNC_N_REFERENCE=
When
card is synchronized to a network PTP
grandmaster clock, this shows which Ethernet port is
being used to receive the PTP clock source
.
