The DOCSIS Shake
#1
So... Im comparing these 2 telnet logs in order to find discrepancies between a subbed (old-security) and a non-prov cm (new security).

I found NO differences whatsoever up to the DHCP Settings; in which the CMTS all of the sudden (each CMTS/log MAC differ cause they're in different nodes) decides that the TFTP server of the non-prov CM will be a 10.x.x.x IP (non-provisioned in my country).

Condition:
Same Sb5101 on both nodes
CVC/HFC MAC Original configuration

The subbed gets 55 TLVs (CPE Access control I guess) Vs. the non-prov gets 33TLVs, resulting in a eventual loop due to "unrecognized OID", in which at a point they are marked as "UNKNOWN, ignoring."

I've checked the DOCSIS Specification manual (an extract oftenly posted by Jr) as a guide on the interpretation of BPI+ authentication process.

At what point will the handshake end?

Thanks!

Off-topic note: There's also in another manual, a lot of emphasis on the synching of a certain element in order to get proper BPI auth., which seems to me very interesting.
