<div dir="ltr"><div class="gmail_quote"><div dir="ltr">Hi all,<br><br>I have an HCA that supports SDR, DDR, QDR, and FDR.<br>I would like to disable the support for FDR. I know about the command:<br><br> ibportstate <lid> <portnum> speed <speed><br> <br>However, this command only enable or disable the speed for SDR, DDR,<br>and QDR. I also saw that the is another parameter for this command that<br>is called <b>espeed</b>. I tried the following command without success:<br><br> ibportstate 1 1 espeed 0<br> ibportstate 1 1 espeed disable<br> ibportstate 3 1 espeed disabled<br> ibportstate 3 1 espeed no<br> ibportstate 3 1 espeed false<br> ibportstate 3 1 espeed down<br><br>Any idea about how to disable FDR ??
