Timestamps in Microengine C
by tabrez rajani 07 Feb '05

07 Feb '05

Hello Everybody, Can anybody tell me how to find the packet receipt rate using microengine C.Basically I need to know if there are any time related functions (such as gettimeofday) etc that I can use in order to find the rate at which the processor is receiving packets.Also i need to record the timestamp for the latest packet from a particular IP address. Any feedback will be appreciated. Thanks, Tabrez. __________________________________ Do you Yahoo!? Yahoo! Mail - Helps protect you from nasty viruses. http://promotions.yahoo.com/new_mail

Simulation Error
by tabrez rajani 31 Jan '05

31 Jan '05

Hello Everybody, I am using the code (in MicroEngine C) for packet reception. ME-0 is used solely for receiving the packets and then enqueing them to the queue. Now I am using ME-1 for some packet processing and then it enqueues this packet again in another queue from which ME-5 reads and transmits the packets. However , in my code for ME-1 whenever I try to access any memory ,(scratch,sram or even local variables for that matter) I get a simulation error. For example I am using the function ixp_cycle_read(); If I comment this out , the simulator works.The error that I get is as follows : ***** %E-ERROR at fbox cycle 545 in simulation ---------- (NOTE: Execution will stop ASAP due to error.): Memory address, 007F8000, is out of bounds of "sdram" array. ***** %W-WARNING: Read of array, "sdram" at address: 007F8000 returns uninitialized data. Simulation prematurely stopped due to error condition. I do not understand why this shows up.I am not accessing the sdram at alll,except for enqueing the packets and dequeing them.At no point am I trying to access SDRAM memory at 007F8000. Do I have to change the build setting or something in order for me to be able to access memory even from the 2nd or 3rd microengines.Are there some memory configurations that I have to change? I'd really appreciate it if somebody can let me know what I am doing wrong. Regards, Tabrez. __________________________________ Do you Yahoo!?

Hi, i' ve read the source, destination IP and source, destination Port frm the incoming packets....haven't tried to read the protocol field...wht exact problem u r facing just let me know tht. becoz as far as i guessed to won't make any difference to fetch any of teh hearder field.... u just look at the bridging example code where they have extracted MAC addresses....it wd. b same.. and currently i'm facing problem to get any info. regarding core processor prog.; if u have any hint do let me know... regards, Nitin On Wed, 26 Jan 2005 tabrez rajani wrote : >Hi Nitin, > >I know that u r trying to implement a firewall so I >guess u r the best person to ask this ? to.

Compuler Error (__mul_ not found)
by tabrez rajani 27 Jan '05

27 Jan '05

Hello Everybody, Firstly I would like to apologize for one too many questions that I have already asked.I have a deadline coming up, hence ... I have a function in which I am using the hash_48 unit.A snippet of my code is : hashInputTmp.hash_lo32 = ip_32; // This is an IP address hashInputTmp.hash_hi16 = ip_32 >> 16; // This is just a filler and the values does not really matter hashInput = hashInputTmp; However I get a compilation error for the following 3 lines of code : hash_48(&hashInput, &hashOutput, 1, ctx_swap); hashIndex = hashOutput.hash_lo32 & 0xff; tableEntry = &(hashTableIP[hashIndex]); (I have followed the same model as in Chapter 8/9) for the hash. Here if I comment out any of the above 3 lines , the compilation error goes away. The error that I get is : (0): error : Function __mul_32 not found I dont see any multiplication here , so I really cant figure out what the problem is. Looking forward to some feedback.

Hi Nitin, I know that u r trying to implement a firewall so I guess u r the best person to ask this ? to. How have u gotten around reading the headers and classifying them accordingly. I know that we have the 8 bit L3-proto after the L2-Source Address. However I have been unable to read the proto byte successfully. I will really appreciate it if you could gimme some pointers on this. Regards, Tabrez __________________________________ Do you Yahoo!? Yahoo!

StrongARM Core and Microengine Memory sharing
by tabrez rajani 25 Jan '05

25 Jan '05

Hello Everybody, I am working on a project in which I have Snort running on the core and the the microengines are used to classify the packets. Now depending on the type of packet , TCP,UDP,ICMP etc the microengines write to specific registers with certian information regarding the packet and also the entire packet buffer. The snort code running on the core will read this information and process the packet accordingly. I will really appreciate it if anybody could how to make the microengines communicate with the core and get them to share memory. Also, is there any way that I can classify the packets using microEngine C. I will not be using the ACE framework. Any pointers or feedback will be greatly appreciated. Regards, Tabrez SUNY-Binghamton. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Hi, the way i have done this is i've a separate IXP1200 evaluation borad which i connect to teh windows2000 host system through PCI(com port) as werll as ethernet port (network), u can connect the target (IXP1200 board) with host(win2000) directly with a cross-over CAT5 cable or throgh normal procedure through ur network... both these connections are required becoz... 1. Com port is basically for initial configuration , say to set up target and host ip, ftp username and passwd. 2. ethernet port is required to download the vxworks image to the IXP1200 board through an FTP connection.. so u also need to setup an ftp server in host machine...where u slect the boot image of vxworks, so that that can b downloaded in the target.. hope this may help a bit... i'll try to search some files which cd. help u...but currently tht wd b in LAB, so will send u tommarow..probably... Btw where r u frm? which university....?? wht. kinda work is going on there,,,,and r intel personals supporting such work?? regards, Nitin Makhija On Tue, 18 Jan 2005 mahin jeyachandran wrote : >Hi, > >I am new to VxWorks and need your best help as possible. > >The problem is, I have installed the ENP2505 board ( Host and Target >are two seperate Windows 2000 machines, connected to each other by a >serial cable (COM1 Port)).

Problem booting VxWorks. Using ENP2505 Board.
by mahin jeyachandran 18 Jan '05

18 Jan '05

Hi, I am new to VxWorks and need your best help as possible. The problem is, I have installed the ENP2505 board ( Host and Target are two seperate Windows 2000 machines, connected to each other by a serial cable (COM1 Port)). The target board (ENP2505) is in the PCI slot of the target Windows 2000 Machine. I did not connect the Target board to network. I set the ENP2505 board mode of booting to VxWorks Module. After the above setup, I opened Hyperterminal (COM1 Port) in Host Machine. Then I powered ON the target system. Now I get some thing like the following Init IXF440 MAC Addresses: succeeded. booting.. VxWorks Board Rev.: 00000000 CPLD Rev.: 000000B4 Value of Personality Register is 00000002 BSP IXP Version: 1.3.141, built on Aug 6 2002, 11:25:30 CPU ID: 6901C124 CPU Speed: 233 MHz Early serial debug initialized Init IXF440 MAC Addresses: succeeded. booting.. VxWorks Board Rev.: 00000000 CPLD Rev.: 000000B4 Value of Personality Register is 00000002 BSP IXP Version: 1.3.141, built on Aug 6 2002, 11:25:30 CPU ID: 6901C124 CPU Speed: 233 MHz Early serial debug initialized it goes on booting like this continuously. I don't know why !!?. If any of you had the same problem pls let me know where I went wrong. Also if possible kindly provide me with the initial seeting and booting VxWorks. Also here are some observation.. when I power on the target Windows 2000 Machine( the one that has ENP2505 board in its PCI slot)... I notice the LEDs glowing in ENP board , but there is no display in the MONITOR of the target Machine. I have Tornado, IXA SDK and ENP sdk.. I installed tornado first, IXA and then ENP SDK in my Host Win 2000 Machine... I also installed BSP for StrongArm in my Host system. Also if possible please provide me with reference materials if possible... your help in appreciated. I know that I make a simple mistake always... but I culdn't figure out.. Please help me. Expecting your reply. Thanks a lot for your help. Regards, Mahin.
