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.

Hi, Ping was not running. In fact the PC kind of hangs ie mouse pointer disappears etc when I connnect. I am able to see the output only after I disconnect.
Configuration: Ethernet port 1 of ENP-2505 is connected back-to-back to the eth1 of the host PC ( PC in which the card is plugged in) through a crossover cable. The IP address of the IXP port is 192.168.1.150 and the IP address of the PC port is 192.168.1.3 .
Also is there any option is the ixsys.config file through which I can specify the rate ? Thanks, Kamesh.
