Sorry forgot the sample capture in the first e-mail.
 
Hello,
 
I am looking for any information as to exactly what Ethereal is looking for in the DOCSIS Packets in order to recognize them correctly.  I currently am receiving the MAC Header and Ethernet Packet info but it seems to be unable to recognize them.  I have an example of the the packets which I am currently receiving below and have attached a sample capture as well.  Can anyone tell me what is missing or needs to be removed?  Any help would be greatly appreciated.
 
c2 00 00 34 d6 89 01 e0 2f 00 00 01 00 30 eb bc 10 0c 00 22 00 00 03 01 03 00 01 01 03 01 00 11 f6 20 00 11 f5 fb 01 06 01 04 ff 40 00 ff fc 40 04 00 01 c0 14 e9 f7 19 84 00 01
 
When I have all of the Protocols enabled under Enable Protocol these packets are showing up as LLC, with Info - I, N(R)=6, N(s)=8; DSAP ea Group, SSAP Banyan Vines Command.  When only the DOCSIS Protocols are enabled the packets show as Unknown, with Info - WTAP_ENCAP = 1.
 
Thanks,
Michael O'Donnell
