<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Hi,<o:p></o:p></p>
<p class="MsoPlainText">this morning we had the issue of a rebooting 7750 which had a overload-on-boot in its isis config.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I failed to find the way to clear the overload.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I instead removed the overload-on-boot and put an overload timeout 60 in the isis config which caused the overload signalling to disappear.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Is there a clear command for overload-on-boot?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
