<p class="MsoNormal"><span style="font-size:11.0pt">I’ll put the details below, but basically: for the Nexus 9k, the debug: filesystem is constantly filling with information, and there’s no way to turn it off. I can manually alter my cisco-nx output (or create
a special-purpose 9k variant) to remove the “dir debug:” and do something about “dir logflash:” output, but I’d prefer to avoid that if I can. What other options do I have, except “live with it”?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Hi Weylin,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><br>
This is William Chong from Cisco TAC – LAN Switching Team and I have ownership of this case. It is my understanding that you are seeing an increase in file size of the debug logs on your Nexus 9k.<br>
<br>
<br>
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Answers to your questions below:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><b><span style="font-size:11.0pt">If this is expected behaviour:</span></b><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The switch will update the bootvar_debug.log file as part of its normal operation. This data is intended for Cisco engineering and TAC.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><b><span style="font-size:11.0pt">What I would need to do to disable it</span></b><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Preventing these logs from updating is not an option as it is part of the switch’s normal operation.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><b><span style="font-size:11.0pt">If I need to be worried about exhausting storage capacity.</span></b><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The debug directory will have a dedicated amount of flash storage for the file, as such, it will not have an impact on the other functions of the switch. You will not need to be worried about exhausting the
capacity.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Please let know if you have any further questions.<o:p></o:p></span></p>
