<p class="MsoNormal"><span style="font-size:11.0pt">There is currently no mechanism to configure a specific compute host to be a PTP master. That would require enhancements to the current PTP configuration since the current default state is to set up only
the internal management network as a PTP slave, and currently that configuration cannot be overridden by the user. We are looking at adding per-interface PTP configuration in the future but depending on the specific device on the compute that you want to
configure as a PTP master, it may not specifically address this scenario.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Can you describe the clocking architecture in more detail?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">What is the device that will be on the compute host that will bring in the clocking source?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Are you looking to redistribute the clock from the compute, so that it behaves as a boundary clock or will it be a grand master?<o:p></o:p></span></p>
