[ofw] ping on WinOF

Hi David,
 
It seems that there are some strange behavior in the logs that you have
sent.
One very strange thing is that there are many arp requests from
SunMicro_00:f7:d9 to  SunMicro_00:f1:71
Asking for the addresses of 0.0.0.0
 
SunMicro_00:f7:d9     SunMicro_00:f1:71     ARP      Who has 0.0.0.0?
Tell 192.168.100.219
(see for example packet #8, 10, 11,14,16, 19 and many more).
 
This is strange in two ways:
1) Why is he asking for address 0.0.0.0 and not a real address?
2) Why isn't this a broadcast message?
 
I guess that this mal-formed packet explains why there is no response:
192.168.100.219 doesn't know where the remote address is.
 
The second strange thing is that all of a sudden, on packet #48
192.168.100.219 starts sending data to 192.168.100.250.
I guess that this can be explained since on packet 47, there was an arp
request from 219 to 250. There are two strange thing here:
1) This is a unicast packet and not a broadcast packet.
2) The same information could have being also learned at frame #4. Why
does he has to wait for packet #47?
This packet is being answered and from here all is well. (ping passes).
 
In order for me to better understand this situation, can you please
repeat the experiment and send me the wireshark log of both sides?
 
Please send them as attachments of .cap files. This makes it easier for
me to see what is going on there.
 
Thanks
Tzachi

			Hello,
			
			An internal customer is using WinOF 2.0.X and
has reported to me the following behavior related to IPoIB and ping:
			
			Do you have any ideas on why windows 2008 client
with HCA may first timeout ping to other clients on the fabric?
			
			Initially ping fails but then starts working.
			
			Example :  Ping is invoked three times
successfully.
			
			C:\GRITS>ping -a 192.168.100.235
			
			Pinging 192.168.100.235 with 32 bytes of data:

			Then we are good for sometime before this starts
again if network is idle on the fabric.
			
			Has this sort of behavior been observed before?
The Linux and Solaris nodes sharing the same IP subnet appear to be
behaving normally.  Windows server is the "out-of-the-box" configuration
with Voltaire switch configured with only the default partition
(0xFFFF).
