TIMESYNC_
N
_NETWORK=
Network port currently being used for synchronization for
IQMIX modules, dependant on the choice of interfaces
made on the Time Configuration page. If PTP and multiple
interfaces are enabled, the PTP synchronization will
switch ports if it doesn't see regular sync messages on
the port.
TIMESYNC_
N
_CLOCK_ID=
Identification number of PTP clock being used for
synchronization. This is not necessarily the grandmaster
clock identity, as there can be intermediate clocks
between the grandmaster and the card, depending on
network configuration.
TIMESYNC_
N
_CLOCK_STATE= Valid values are:
•
Free running
: Card is not being synchronized.
•
No Lock
: PTP being used but clocks haven't
synchronized /- 1mS.
•
Locked
: PTP being used and clocks are within
the accepted range.
•
NTP
: Module using NTP to synchronize.
TIMESYNC_
N
_AVG_DELAY=
The current network delay time between the card and the
clock sending the synchronization messages. This should
be relatively constant and is dependant on network
configuration.
TIMESYNC_
N
_STDV_DELAY=
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=
The current difference between the cards time and the
grandmaster time. Should be close to zero once card has
synchronized.
TIMESYNC_
N
_STDV_ERROR= The standard deviation in the average error.
TIMESYNC_
N
_
GRANDMASTER=
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=
Time when the module last changed from not locked to
locked. Ideally this will be a few seconds after the module
has powered up. This allows the user to confirm which
clock the module has synchronized to.
TIMESYNC_
N
_
SYNCHRONISATION=
Reports 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.
LAN_PORT_
N
_NAME=
Ethernet port name as defined by the OS.
