[Linuxptp-users] ptp4l and multiple network devices

[Vadim B. <va...@gm...>]

Hi,

First of all, thanks for ptp4l. You did an awesome job!
I'm using two PTP cameras connected to two ethernet network devices
(non-PTP) on my PC, and I'm trying to sync them by using the software PTP.

I tried doing it in the following way:
1. I start the first device as a master:
sudo ptp4l -i enp7s0 -m -S
ptp4l[2549.662]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[2549.662]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[2556.924]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_
EXPIRES
ptp4l[2556.924]: selected best master clock 78d004.fffe.227db5
ptp4l[2556.924]: assuming the grand master role

2. I start the second one in a slave mode:
sudo ptp4l -i enp6s0 -m -S -s
ptp4l[2564.849]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[2564.849]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[2571.141]: selected best master clock 78d004.fffe.227db4

I don't think it did a right job since the slave clock has a different name
than the master clock.

Can you please give me a hint on what is the proper way to do it?

Thanks
