<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I have been using utility “ibportstate” from “infiniband-diag 1.6.1” package to force lower link up speed.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">It’s working properly until I upgrade to newer version of “infiniband-diag 1.6.2” or ““infiniband-diag 1.6.4”. Example of “ibportstate 2 1 speed 1” does not seem to have any effect. Does anyone know the potential
causes?<o:p></o:p></span></p>
