<p class=MsoNormal style='background:white'><font size=3 face="Times New Roman"><span
style='font-size:12.0pt'>This issue is system issue that prevents from
partial P_Key setup to<br>
go into production.<br>
<br>
<br>
Short Setup & test description:<br>
------------------------------------------<br>
* Node A: P_Key XXX (full member)<br>
* Node B, C, D, E, F: P_Key XXx (partial member)<br>
<br>
1. Send ping from B -> A : ping is OK<br>
2. Send ping from C -> A : ping is OK<br>
3. Send ping from B -> C : no ping also OK<br>
* Get traps Bad P_Key in SM - from all HCA in the fabric both for<br>
test 1 & 2 (one time) and also for test 3 (all the time).<br>
<br>
Probably the ARP request that is MC traffic generate the trap in HCA, for
test 1<br>
& 2 we have only one ARP but for test 3 we send ARP all the time because<br>
we do not get any ARP reply.<br>
<br>
* The trap number SM get is 257 (HCA trap) if we will do P_Key<br>
switch enforcement we will probably get 259<br>
.<br>
* We get trap also from the originator of the MC traffic even<br>
though that receive switch relay error counter is increased (when out<br>
port==in port), the switch does not drop the packet ?<br>
<br>
Additional questions/issues:<br>
* Do we have a way to suppress port traps from SMA ?? i.e. that<br>
the port will not generate traps that can "kill the SM" - as its look<br>
this is bug in the spec where we can't send any mc traffic (even ARP)<br>
when we have partial members and we do not have a way to suppress the<br>
traps.<o:p></o:p></span></font></p>
<p class=MsoNormal style='background:white'><font size=3 face="Times New Roman"><span
style='font-size:12.0pt'><br>
* What will happen in the HCA when we get many traps (mc packets<br>
from many nodes) and they need to keep all events until SM will<br>
acknowledge? - Is there limitation in the number of on-going<br>
traps (any HCA specific issues)?<o:p></o:p></span></font></p>
