Please forgive me to let me clarify my question: How to communicate my IXP1200 ENP2505 Card with my PC using Ethernet ports presented on the ENP2505 card? Yes, I can boot the IXP1200 using serial cable, and also can ping my PC through PCI bus. Thanks. On Wed, 20 Nov 2002, Ye, Irvin wrote:
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.

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
