Dear @McGrady,
I will check internally and update you.
May I know how did you test it? Did you run any additional commands for this test?

Thanks for your reply.
I use the command “sudo tcpdump-i mgbe2 0 -w 1.pcap” to save the network messages of mgbe2_0 whitch connected to the switch1, and use wireshark to lodad the pcap file, and I can see the ptp time is 0, not the corrent time.

Dear @McGrady,
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
