All,<br><br><br>I am trying to have a better understanding of how the SM and IPoIB interact with respect to arp. If there is a document that describes this please point me in the right direction.<br><br>In the past, (OFED 1.0 and pre OFED 1.0) I observed the the following:<br>
<br>1) Using hosts A,B<br><br>A> ping B (succeeded) <br>A> opensm stop<br>A> arp -d B<br>A> ping B (Failed)<br><br><br>2) Using opensm-3.1<br><br>A> ping B (succeeded)<br>A> opensm stop<br>A> arp -d B<br>
A> ping B (succeeded)<br>A> ping C (failed)<br><br><br><br>In scenario 2, what allows the arp query for B to be resolved after the SM is stopped and arp entry cleared?<br>Is this due to connected mode, in that an RD connection is already established?<br>
Or is there an underlying cache that feeds the ARP cache?<br><br>Thanks,<br>Todd<br>
