Hi,

I've tried to setup the ixp1200 card to do l3fwdr by using the example config file ixsys.config-sys-l3fwdr. I also modified the file since the card has only 4 10/100 ports. I modified route.config-sys-l3fwdr file to add a default gw. Everything was loaded fine when I run ixstart, however I wasn't able to ping other hosts in the same subnet and the other way around. I also tried to add the arp table entry manually but it still didn't work. Could someone help me? I'll be glad to provide you the config files if that helps.

Hi Jagan, I think the problem could be from .wine/config settings as PATH and/or registry (you need to get imported the DevWorkbench keys from Windows installation) Best regards, Mihai

I also tried "manually" assembling one of the microcode (rcv.uv) by going into the Vera/bin/ directory itself,where uca..exe is present and then run the wine simulator with the parameters taken from a previously failed make. i.e I did /usr/bin/wine.bin -- uca -m /scratch/UDP_Vera/Vera/bin/uword.def -p /scratch/UDP_Vera/Vera/bin/ucc.def -P -I../../common/include -DUSE_REGALLOC -DLITTLE_ENDIAN -DBIG_ENDIAN=0 /scratch/UDP_Vera/Vera/Libixprouter/ue/src/rcv.uc ... And here I get an error saying that it was not able to read the rcv.uc file !!! ( But NO error for .def files strangely) I think I have not done something for my Wine simulator configuration. i.e it looks for /scratch/myVera/Vera/Libixprouter/ue/src/rcv.uc , probably "relative" to something and this fails. Should I do anything with my "locale" setting ? I added a path to xmessage by appending /usr/bin/X11/ to the path. Any idea is greatly appreciated. Jagan.

Hi Mihai,

Thanks for your email.

I have difficulty in getting you. Could you please be more specific ? I see a Path variable in my .Wine/config which can be set to /floppy or /cdrom or "/home/vjagan/.wine/fake_windows". Wen I ran wine for the first time, I gave the "/home/vjagan/.wine/fake_windows" as the place to create the configuration directory.

BTW what is "DevWorkbench keys" ? I really do not know what it is.

Hi, I am also facing a similar problem. I renamed the ixsys.config-l3fwdr file as ixsys.config and ran ixstart. I saw 17 interfaces being created even though there were only 4 ethernet ports on the ENP-2505. Is there a way in which the physical ethernel ports can be bound to the created interfaces ? If there is no way to bind, how can the interfaces (eth1,eth2,...) be mapped to the actual physical ports ? Kamesh. Istvan Matyasovszki wrote:

Hi there-

You mention a great deal of link level activity. Have you done a TCP dump?

Make sure all interfaces are 100 Mbps and see if that helps...

Hi Kameswara,

I guess you have already tried to connect the PC port to the IXP port without going thro' the hub as Cyrus suggested. Just to rule out any autonegotiation problems betweem 10/100 hub and IXP port.

So is ping running when you captured that tcpdump output? Also, what are the interface addresses of the IXP port and the PC port in your setup?

Hi Abijjet, Here it goes. The host is a PC running RedHat 7.2 . The ENP-2505 card is in one of the PCI slots of the PC. The OS on the ENP-2505 is linux. There is no Window NT machine. We are using the .uof file that come precompiled along with the SDK CD. When the script ixstart is run, no errors are reported. The ports 0 and 1 are attached to microengine 5 ( found this out after adding trace statements in resource manager files). When I do a lsmod the stackAce is shown as initializing. By "PC is hanging" I mean that I am unable to do any activity. The mouse pointer disappears, keyboard freezes etc. I think this is because of the FULL_DUPLEX option in port configuration in the octmac.c file. I changed it to HALF_DUPLEX and I no longer see the problem. When I do a ping I get the trace message "Ring to microengine full" after sometime. I am guessing that the microcode that de-queues messages from the ring is not running or not loaded on the micro engine. I hope I have given enough info. Thanks, Kamesh. Abhijeet Joglekar wrote:

Kamesh,

Sorry, couldnt get back earlier.

In general, it is very difficult to figure out remotely what the problem with your set up could be. For example, it could be a simple misconfiguration in your startup files or something as crazy as a bad ethernet port on the card or the PC (although it is unlikely).

Can you describe in more detail your complete hardware and software setup? What is the output on your console when you fire up your ixstart script? Do all ACES start up properly? Is anything printed on the IXP console when you ping or connect the port to the PC? Try turning on debugging in ingress/egress ACEs to see if they report any activity on the connected port. (Makefile has debug defines)

What do you mean below by "PC hangs when I connect" ?

Basically, explain in detail, maybe somebody on this list can help.

Andrew, Is your l3fwdr application set up okay by now? The ixconfig program, l3config and stackconfig all use the ixsys.config file (or ixsys.config-sys.l3fwdr), as long as you pass the correct file to all programs, it should work fine. The possible places to check are 1) what you pass to ixstart as an argument 2) in your ixsys file, the two "sh" commands which invoke stackconfig and l3config apps. Have you tried running the Count application? If not, you could try that first, if that works, you know that the rest of your setup (end-nodes) and switches are setup correctly and packets are coming into the IXP. If packets are indeed coming into the IXP, then try enabling debugging in ingress ACE to see whats happening with the packet when it comes in. Also, try with mode=0 (no workbench) in the config file. -- abhijeet On Mon, 20 Jan 2003, Andrew Putra Jauri wrote:
