<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D;mso-fareast-language:EN-US">Hi Philip, you can capture PTP packets using tcpdump command with the “ether proto 0x88F7” parameter for L2 or “udp port 319 or udp port 320” in case of UDP.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D;mso-fareast-language:EN-US">Wireshark is very helpful in understanding of PTP packets flow. Also, the pmc command is available for you to check the PTP port status and see what’s going on.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D;mso-fareast-language:EN-US">For example, “pmc -u -b 0 'GET PORT_DATA_SET” and pmc -u -b 0 'GET TIME_STATUS_NP' are the most useful ones in analyzing slave/master interactions.<o:p></o:p></span></p>
