[Linuxptp-devel] Configuration file and parameters

[Rohrer Hansjoerg]

Hello

1. userDescription is implemented in source code to be read from config. file, but missing in config files (examples).

2. To use ptp4l as Grandmaster, at least the timeSource parameter should be available in config file.

3. How can ptp4l as Grandmaster be informed, that the clockClass changes in running mode (without restart)?
E.g. clockClass from synchronized (6) to holdover (7) and back.
I think there sould be some sort of reread of the config file while running, e.g. HUP-signal....

Best regards
Hansjörg

Okay, easy to fix.

Also easy to add.

Short term solution:
Instead of HUP, you can just do: killall ptp4l; ptp4l -f new_config.

I think the bet way to allow changing such things would be using the
management interface, via the UDS. While there is no standard message
for setting clockClass, we can reasonably add a private one for this
purpose.

This is a bit more work, but it is something I had wanted to add,
eventually. Now that someone is asking for it, I have a reason to
implement it right away...

Thanks,
Richard

Agreed, the best way would be a private method over the UDS management interface.
