Instance Specific Considerations

ptp4l
|
|
=====
|
|
|
|
**Default global parameters**
|
|
|
|
* tx_timestamp_timeout 20
|
|
* summary_interval 6
|
|
* clock_servo linreg
|
|
* network_transport L2
|
|
* time_stamping hardware
|
|
* delay_mechanism E2E
|
|
* boundary_clock_jbod 1
|
|
* uds_address /var/run/ptp4l-<instance name>
|
|
* uds_ro_address /var/run/ptp4l-<instance name>ro
|
|
|
|
**Default interface parameters**
|
|
|
|
NONE
|
|
|
|
**Required user-supplied parameters**
|
|
|
|
``domainNumber <number>``
|
|
|
|
**Other requirements**
|
|
|
|
An interface with a port must be assigned to the ``ptp4l`` instance in order
|
|
for it to start.
|
|
|
|
phc2sys
|
|
=======
|
|
|
|
**Default global parameters**
|
|
|
|
``cmdline_opts '-a -r -R 2 -u 600'``
|
|
|
|
**Default interface parameters**
|
|
|
|
NONE
|
|
|
|
**Required user-supplied parameters**
|
|
|
|
``domainNumber <number>``
|
|
This should match with the associated ``ptp4l`` instance.
|
|
|
|
``uds_address <path>``
|
|
This value needs to be the same as the uds_address for the ``ptp4l``
|
|
instance that ``phc2sys`` is tracking.
|
|
|
|
**Other requirements**
|
|
|
|
The ``cmdline_opts`` are defaulted to support interaction with ``ptp4l``. If
|
|
``phc2sys`` is instead being used with ``ts2phc``, this parameter will have to
|
|
be updated. See :ref:`ptp-instance-examples-517dce312f56` for more information.
|
|
|
|
.. note::
|
|
|
|
|
|
The ``cmdline_opts parameter`` overrides all default command line flags for
|
|
the service. This means that when setting ``cmdline_opts``, the full list
|
|
of desired flags should be set.
|
|
|
|
|
|
ts2phc
|
|
======
|
|
|
|
**Default global parameters**
|
|
|
|
* ``ts2phc.pulsewidth 100000000``
|
|
* ``leapfile /usr/share/zoneinfo/leap-seconds.list``
|
|
* ``cmdline_opts '-s nmea'``
|
|
|
|
**Default interface parameters**
|
|
|
|
``ts2phc.extts_polarity rising``
|
|
|
|
**Required user-supplied parameters**
|
|
|
|
This value is the path to the GNSS serial port that is connected, it will be
|
|
named differently on each system.
|
|
|
|
``ts2phc.nmea_serialport=/dev/ttyGNSS_BBDD_0``
|
|
|
|
**Other requirements**
|
|
|
|
An interface with a port must be assigned to the ``ts2phc`` instance in order
|
|
for time to be synced from GNSS to the phc.
|
|
|
|
clock
|
|
=====
|
|
|
|
**Default global parameters**
|
|
|
|
There are no supported global parameters for clock type.
|
|
|
|
**Default interface parameters**
|
|
|
|
NONE
|
|
|
|
**Required user-supplied parameters**
|
|
|
|
NONE
|
|
|
|
**Other requirements**
|
|
|
|
The clock type instance is a special instance used for configuring the NIC
|
|
control parameters of the Westport Channel or Logan Beach NIC clock
|
|
interface parameters.
|
|
|
|
These parameters can be applied to the interface of a clock instance |PTP|

parameters:

|
|
* sma1 input/output
|
|
* sma2 input/output
|
|
* u.fl1 output
