Ethernet ARP
by Chong Lee 30 Aug '04

30 Aug '04

Hi everyone, Currently I am trying to implement Ethernet ARP module using IXP1200 in my project. Besides implementing ARP module, my project will focus on detect and prevention of ARP cache poisoning. My idea of implementing detect and prevention for ARP poisoning is by setting up a checker for both downward and upward of ARP request. hope to get some advices and ideas from this forum... btw, just wanna know, which reference design in workbench developer would be best suit this project?.. thanks.. Thanks. ===== Best wishes, Kuay, Chong Lee __________________________________ Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers! http://promotions.yahoo.com/new_mail

file operations in .ind scripts?
by Arvind Giridhar Saraf 17 Aug '04

17 Aug '04

Hello, I am using IXP1200 simulator, and want to run an existing IXP1200 application with my routing table inputs. Currently, the applications routing table is set in .ind scripts using route_add function. The routing table I want to use instead is in a text file, and I will like a .ind script that reads the file and sets the application's route table accordingly. I don't see any clear support for that in the .ind scripts. Can anyone suggest how to do this? Thanks, Arvind

Using the Ethernet ports of BV card
by Ing. Ricardo Camarena Ramos 13 Aug '04

13 Aug '04

Hi, I am trying to simulate in hardware the practice number 5. I have a BV card. The results I got when simulating in Workbench are correct, however when simulating with the card I never got any packages to count. I must say that I have simulated in hardware practice 3 (writing an array to memory and reverse it) and everything worked fine, I even used a tool from Georgia Tech to look at the memory of the board to double check the results. So here is what I have investigated until now, the value of rcv_rdy_lo when simulating only with Workbench is x1, x2, x4 and x8 when feeding packets in ports 1,2,3 and 4. Up to here is correct. When I change to hardware and after loading ue.o , running rs_udebug and assigning MACs through octmac.o the rcv_rdy_lo behaves incorrectly. It gives x200, x400, or x800 for packets arriving at ports 2, 3 and 4 (and nothing when feeding in port 1). I got a document indicating this problem has to do with an different distribution of MACs in the IX-Bus and instructed to me to apply these corrections: Replace the config_1200.cpp located in /opt/ixasdk/src/microace/common/wbench/SA1_CoreLibs/app_1200/ Replace board.h a located in /opt/ixasdk/enp-2505/src/linuxIXAedu/include/asm-arm/arch-ixp1200 Recompile kernel and octmac module cd /opt/ixasdk/enp-2505/src/linuxIXAedu make oldconfig make dep make zImage cd /opt/ixasdk/src/microace/aces/interface_ace/source/driver/octdrv/ make make install I verify zImage and octmac.o were updated, but I got the same results. It seems the corrections are not working. The last test I did was to modify the practice five writing the counters to SRAM instead to scratch, so I can inspect the memory with the Georgia Tech tools, but I got the same results. No packets are count. Any help or tip to solve this problem is very appreciated.

NePSim: A Network Processor Simulator with Power Evaluation Framework
by Yan Luo 11 Aug '04

11 Aug '04

Hello All, We are pleased to announce the release of NePSim 1.0, the first open source integrated infrastructure for analyzing and optimizing Network Processor design and power dissipation at architecture-level. NePSim contains a cycle-accurate simulator for a typical NP architecture (Intel's IXP1200), an automatic verification framework for testing and validation, and a power estimation model for measuring the power consumption of the simulated NP. Four typical benchmark applications (ipfwdr, nat, url, md4) are included in the package. A paper on NePSim is going to appear in the coming IEEE Micro Special Issue on Network Processors for Future High-End Systems and Applications, Sept/Oct 2004. You are welcome to download NePSim from http://www.cs.ucr.edu/~yluo/nepsim/ We have set up a mailing list at https://www.cs.ucr.edu/mailman/listinfo/nepsim You can use the above mailing list, NOT this ixp1200 mailing list, to ask questions, report bugs and get more information. Thanks. Best Regards, Yan Luo -- yluo(a)cs.ucr.edu Computer Science Dept., Univ. of California Riverside, CA 92521, USA http://www.cs.ucr.edu/~yluo

Hellow..

Hellow, i'm just tring to understand how can i get information out of header of mpkt...so made few changes in eg. code of chapter 5 (which counts the mpkt's)...but not able to understand where m i going wrong...actually i'm not getting expected results.. changes which i made...... 1... added a new structure in buffer.h file typedef struct { unsigned int e_dst_hi32; unsigned int e_dst_lo16 : 16, e_src_hi16 : 16; unsigned int e_src_lo32; } ethernetHeader_t; 2... declared a pointer to this new type and it points to the buffer_handle (adress returned by a function where mpkt. is stored by RFIFO) 3... just checking whether lower 16 bits of dest mac is 0xffff or not...in a if-else block ,,,,,inside while function of main() 4....i have edited the stream, from ix simulator to have mac address as 0xffffffffffff the if block which i added in the main in receive.c file ... if( headerData.e_dst_lo16 == 0xFFFF ) scratch_incr(cntr, no_signal); else scratch_incr(cntr_blocked, no_signal); in this case cntr_blocked is incremented instead of cntr , which is expected. can u expain where m i going wrong... regards, Nitin Makhija
