How to read sent raw Ethernet frame on PC?

[trilokjt]

Hi

I'm  working on Mk60N512 board, I wrote code to send the raw Ethernet frame. How can read the read the frames on PC(Ethernet cable connected to PC)? I used wire-shark to read frames but it is receiving only IP type I couldn't able to read the frames that have sent from board. I just wanted to read raw frame! Please can any one tell me good tool/software to read the sent frames?

Please do solve my issue I'm working on this since 1 month, I need to resolve and move further to proceed with my project.

Hoping for sooner reply

Thank you

Hi Trilok.

Please,

- does correctly communicate between your board and computer?

- do you have correctly set Wireshark?

Please, did you set it in promiscuous mode?

Thank you.

Hi Iva Dorazinova.

Thank you so much for replying soon.

1. Im not sure whether it's connected properly to PC because after connecting board(Switched On)  to Pc, in PC Ethernet connection is showing as unidentified network and once I enter into debug mode, network will go off and try to find network (Identifiyig Network) after few secs/min it will reconize as unidentified network. How to make sure board is able to communicate with PC properly?

2. No I not set promiscuous mode, I'm not aware of this  where do it exists and how to set?

Thank you.

Hi Trilok.

the easiest way is execute command window (cmd) and type ping the ip address of the board.

For example: your IP address of the PC will be 192.168.1.100 and your device will be set on 192.168.1.102, be sure that ethernet cable is connected between the PC and the board, open the cmd and type ping 192.168.1.102.

You will see if the connection was susscesful.

In case of any issue, please let us know.

Have a nice rest of the weekend.

Hi Iva Dorazinova

I dont know the IP of the board, I just changed the MAC of  board. How to know the default IP of the device or Set the IP of our own wish.

I have another doubt I.e.,on PC network ico, Ethernet network shows unidentified network. If I enter into debug mode it goes off( Shows identifying network...) and after few sec PC again recognise board network as Unidentified network!!! What's the issue? Is Board connected properly or not?

Hi Trilok.

Please, what do you use for the code in your device?

Because the IP Address you set in the code,

for example, if you will flash KSDK code, example lwip_tcpecho_freertos for your board,

there you should set the connection in lwip_tcpecho_freertos.c

so, the board is set on 192.168.1.102 and PC is set on 192.168.1.100

/* IP address configuration. */
#define configIP_ADDR0 192
#define configIP_ADDR1 168
#define configIP_ADDR2 1
#define configIP_ADDR3 102
/* Netmask configuration. */
#define configNET_MASK0 255
#define configNET_MASK1 255
#define configNET_MASK2 255
#define configNET_MASK3 0
/* Default gateway address configuration */
#define configGW_ADDR0 192
#define configGW_ADDR1 168
#define configGW_ADDR2 1
#define configGW_ADDR3 100

I hope this helps you.

Best Regards,

Iva

I got to know about promiscuous mode,

I'll check it once and let you know.

Try this tool....   ::SocketTest:: - Test My Socket

Hi Peter

Thank you for replying.

Is That tool able to receive raw Socket? because in description of page shows it can only receive/send only UDP/TCP  Packects.  Anyhow I'll check it And let you know.

Thank you.
