Is the server configured with the same logAnnounceInterval? If the
client had a shorter interval, it would time out and lead to
the uncalibrated state. I'm not sure about faulty. Can you post the
client log?

[Linuxptp-users] inconsistent Message rates

[Gururaj B. <gur...@gm...>]

Hello,

I have been using ptp4l with the below config file. What I noticed was -

In Follower mode, when 'Announce Interval' set to more than 4Hz (4 messages
per second config value -2) and 'Sync Interval' set to more than 8Hz
(8messages per second config value -3), I see ptp4l lock status toggling
between "Faulty" to "ÜnCalibrated" to "Slave" to "Faulty" and cycle
repeats. The lock status is not getting stabilized.

Below is the config file I'm using to run ptp4l in Follower mode.

You can slow down the corrections of the system clock made by chronyd
by increasing the corrtimeratio (e.g. to 100 or 1000) and/or slow down
the corrections of the PHC made by phc2sys by setting smaller PI
constants (e.g. -P 0.04 -I 0.00024).

The latter will not make the offset reported by the server phc2sys
smaller, but it will make the clock easier for the clients to follow,
i.e. keep the offset between the clients smaller, which I assume is
what you are primarily interested in.

[Linuxptp-users] Syntax to use PMC with SET command

[Gururaj B. <gur...@gm...>]

Hello,

I'm a new user of ptp4l.
I understand that for some of the parameters such as PRIORITY1,
PRIORITY2, PORT_DATA_SET_NP etc., PMC command provides the option to SET
the values to ptp4l.

Could you help me with the syntax on how to use the PMC SET command via
shell.

Guru

[Linuxptp-users] Question about large gap of offset on phc2sys with chrony

[심준영 <joo...@42...>]

Hi all,

I have a problem on my system environment using chrony and linuxptp.

There are two machines on my local network. One is ptp4l master and another
is
ptp4l slave. The ptp4l master machine uses chrony to update system clock and
also phc2sys updates PTP hardware clock from system clock.

The ptp4l slave machine doesn't use chrony and any NTP daemon, it updates
system clock using phc2sys from PTP hardware clock.

My problem is to cause too large gap between system clock and PTP hardware
clock
for a short while, whenever chrony synchronizes time from external NTP
server
(Poll is 6, so about 64 seconds) and then will affect to PTP hardware clock
and
system clock of the ptp4l slave machine.

Are there any ideas to keep stable small gap even though using NTP like
chrony
to update system clock?

Below is a phc2sys log from ptp4l master machine. The offset increases to
-2136ns from under 100ns when chrony synchronizes time from external NTP
server.

You have the step threshold set to 1 ns, but the log below shows
larger offsets, which means it's frequently stepping. You should
increase the threshold.

If you want to synchronize to the average offset instead of sticking
to the first measurement, you can use the PI servo with small
constants.

This topic was discussed here recently:
https://www.mail-archive.com/lin...@li.../msg02822.html

In short, there is no HW support, SW timestamping doesn't make sense,
don't use PTP over wireless networks.

[Anh N. <ngh...@gm...>]

Hello,
I have been using linuxptp in a wired network but now I would like to try
using a mixed configuration. However, my NIC seems to not support the
operation as it is missing tx_software. I have read that it would require a
modification to the driver but I have no experience in the matter and would
like to ask if there is any example to help.

ptp4l prints the estimated network delay of sync messages including
timestamping errors.

phc2sys prints the time it takes to read the system clock and
hardware clock in order to measure the offset. That includes delays in
the CPU, PCIe and the NIC.

You can enable clock steps with the step_threshold option. See the
ptp4l and phc2sys man pages.

path delay output from ptp4l of the slave?
I know the path delay as the expected delay time of the sync message sent
from the Master, but I'm not sure about the concept of delay.

2. If you change the master's time arbitrarily while PTP time is
synchronized by entering the command written above (example: change the
time randomly by entering date -s '2012-01-01 00:00:00' in the master) Is
there a way for the Slave to automatically synchronize accordingly? (Or is
there an option to synchronize it to the master's clock every specific
period?)

Any advice would be appreciated.

This issue is observed on NIC PHC and apart from ptp4l no other process will update the NIC PHC in this case.

Will process (ptp4l) scheduling have an impact on this?

On what hardware? SW or HW timestamping?

It could be a driver bug. It could also be another program adjusting
the clock, like an NTP client.

There should be no difference between -2 and -4 in your setup.
I would just use the default of -4.

[Linuxptp-users] How to interpret the global ptp4l statistics at the bottom of the output?

[Jukolas J. <juk...@gm...>]

I am getting the following output from the ptp4l command on a slave PTP
node. When I terminate it (with Ctrl+C), some global statistics are printed
out at the bottom, but I cannot interpret the values, as I do not find any
evident correspondences with the values in the above output. To be precise,
I know what the fields offset, min, max should be referring to in general,
but:

   1. why are there pairs of values instead of single values for each of
   those fields?
   2. what is "dev" actually? If it's the standard deviation "of
   something", what's the point in having the min and max subfields?
   3. how are those pairs of values supposed to be computed or related to
   the above recordings?
   4. can you explain the meaning of drift, especially?

The client has Announce messages timing out.  (Announce does not get a time stamp at all)
Maybe message rate config mis-match?

port 1: UNCALIBRATED to LISTENING on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES

Which leads to a loss of synchronization.
I don't see an error on the master side. I have added a tx and rx timestamp
output and I see that the master does not stop.
So I understand the problem is on the slave side.

Best regards,
Vyasheslav
