[ixp1200] SOS, a question about connection and output!

[Ye, Irvin]

No need to do any configuration, ixconfig will do for you.
 
As for packet generator, Intel suggest use IXIA or Shomiti, but I even don't
know what are they? Who know? do tell me. If they're some kinds of special
devices, I can't afford, I'm affraid. So I just use Linux host to generate to
packets.

Irvin, 

Sorry for not trying to answer your question, but  ask you question.... 


Q1: My case is I reboot my target(IXP1200) from my host machine through a
serial cable, and I can ping each other via virtual interface( PCI) as well.
Now I want the two system(IXP1200 and my host Linux machine) communicate by
Ethernet port  via a cross over cable. My question is : what is the detail
steps that I should do, such as network configurations or other? That will be a
great help for me if you would like share your experiences or point me the the
documentation that you followed.  
Q2: What is the packet generator that you used? 


Thanks a lot. 


Ning

Hi,I'm puzzled on the connection for ixp1200.I had tried to connect PCs and
ixp1200 ports in standard way: via a hub / switch, but it failed to work. When
I tried direct connection through crossover twisted pairs, it seemed OK,
packets could be successfully sent to ixp1200 ports. But then it found that
packets could not be sent from the ports. When I tried Intel's simple bridge
example, I found there were problem in the egress side: packets could not be
sent out, so finally there was a RmSendPacket error. Upon Erik's suggestion,
I've checked some status of the board and found that when there were packets to
send, the value of the XMIT_PTR regisger would stick to a fix number, and the
active transmit thread would cycle around these codes:
Egress_WaitForPortReady[abs_port]    ctx_arb[sdram]I've tried long, but failed
to resolve the problem. It's making me crazy. Who can give me a
help?Regards.Irvin
