Hi, Nimit,

I've tried Intel's samples, both l2bridge and l3forward, but failed to let

work. There're always errors in the egress side. The ueng always stops to wait for the ports to be ready, while the ports keep unready. Would you give me some hints?

Ning... Try running the hardware version of the l3fwdr project on the IXP by configuring it for the number of interfaces you want to use.

Please forgive me to let me clarify my question:

How to communicate my IXP1200 ENP2505 Card with my PC using Ethernet

...

presented on the ENP2505 card?

Yes, I can boot the IXP1200 using serial cable, and also can ping my PC through PCI bus.

Thanks.

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

Irvin, What config file(s) did you use when you called "ixstart" for the l3fwdr? -Nimit ----- Original Message ----- From: "Ye, Irvin" To: Sent: Thursday, November 21, 2002 5:25 AM Subject: RE: [ixp1200] How to communicate IXP1200 ENP2505 card with PC using Ethernet ports them ports through

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

Thanks a lot.
