<p class="MsoPlainText"><span lang="EN-US">Hi All,<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">We want to implement two network Ethernet interface properties</span><span lang="EN-US"> “Bandwidth” and “Drop package rate”,
</span><span lang="EN-US">and expose the information via Redfish. The goal is that clients can talk to bmc via Redfish and get those two information. It will improve the debuggability of BMCs.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">About the implement method, we divide the work into two parts: phosphor-network(or other suitable service) part, and bmcweb part.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">For phosphor-network part, we propose to use existing tool like ipert to get the Ethernet BW/</span><span lang="EN-US">Drop package rate. Or the other method is that
</span><span lang="EN-US">read TX/RX from ethernet driver (/sys/class/net/{Ethernet_Name}), then calculate the BW/</span><span lang="EN-US">Drop package rate. After that, we will need to register the D-Bus interface and sync the property info to that D-Bus.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">For bmcweb part, as I know so far, there has no suitable field under the
<a href="https://redfish.dmtf.org/schemas/v1/EthernetInterface.v1_7_0.json">EthernetInterface
</a>to set </span><span lang="EN-US">BW/</span><span lang="EN-US">Drop package rate. The idea is that read the value from D-bus then set the properties under the EthernetInterface OEM field. Please let me know if I have missed anything.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">We are willing to see any suggestions and alternatives as well. Thanks!<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">Sincerely,<o:p></o:p></span></p>
