Re: [Linuxptp-users] ptp4l on NIC with multiple IP addresses

Dear Richard, thank you for your answer. The client is a Livox LiDAR ( https://github.com/Livox-SDK/Livox-SDK/wiki/Livox-SDK-Communication-Protocol) which operates in the 192.168.1.x/24 subnet. It definetly synchronizes if the PTP grandmaster's source IP address is in the same subnet. But PTP sync

Re: [Linuxptp-users] ptp4l on NIC with multiple IP addresses

Hi Timo, not sure if I understand your setup correctly, but could it be that you have an issue with reverse path filtering on the client!? You could check that by setting the following on the client side: sysctl -w net.ipv4.conf..rp_filter=2 cheers, Christian Von: Timo Korthals Gesendet: Mon

Re: [Linuxptp-users] Path delay is getting smaller under heavy traffic

Hi, I ran a deeper investigation with a simple experiment. - I ran my test twice - with and without traffic. - I ran it on two different setups (both master and slave are using HW timestamping): - Master (Banana Pi with embedded KSZ9477 switch) <--> Slave (Banana Pi with embe
