Goodday to you all

 

Could someone please help me with the settings for Ethereal to view a DOCSIS frame. I have tried but it keeps interpreting my docsis frames as ethernet frames. I am using Ethereal 0.9.14.

 

Below is a sample of the output that I am getting via Ethereal.

Frame 303389 (600 bytes on wire, 600 bytes captured)

    Arrival Time: Aug 20, 2003 06:59:42.641087000

    Time delta from previous packet: 0.001213000 seconds

    Time relative to first packet: 76.641087000 seconds

    Frame Number: 303389

    Packet Length: 600 bytes

    Capture Length: 600 bytes

IEEE 802.3 Ethernet

        0101 010. .... .... = N(R) = 42

        .... .... 0100 010. = N(S) = 34
