Possible NDK Bug - shifted source MAC address

Eran Gonen

We have an issue in our DSP based decoder (642). Every now and then the decoder transmits an Ethernet service packet (~50 bytes long). In this packet, the source MAC is shifted by two bytes causing a false source MAC address and host flapping.

We’re using NDK 1_93 and DSP BIOS 5.33.03.

Does anyone know this bug? Does it have a fix?

David,

The customer also tried to use NDK 1.94 and the problem still exsists.

Hi,

Can you let me know what type this "eth service packet" is? ARP? Any chance you can upgrade to latest (NDK 2.0) and retry to see if the problem persists?

Thanks,

Marian

Hi,

We are trying to migrate in to NDK 2.0. So far, we are unsuccessful.

This is the problematic packet: (the first 00 10 are redundant)
