SB5101 Running Rev 39 stopped working in SoCal area w/ telnet log.
#2
(CmDocsisCtlThread) BPKM enabled. starting BPKM key requests.

Not submitting the BPKM key. Unless you know TELNET and a trick, I would say your done...as your failing a key item here...

Its very simple but the answer is finding it.

DOCSIS Baseline Privacy (BPI) provides data privacy across the hybrid fiber-coaxial (HFC) network by encrypting traffic flows between the modem and the cable operator's Cable Modem Termination System (CMTS).

BPI security services are a set of extended services within the DOCSIS MAC sublayer. Two new MAC management message types, BPKM-REQ and BPKM-RSP, are employed to support the Baseline Privacy Key Management (BPKM) protocol.

The BPKM protocol does not use authentication mechanisms such as passwords or digital signatures; it provides basic protection of service by ensuring that a modem, uniquely identified by its 48-bit IEEE MAC address, can only obtain keying material for services it is authorized to access.

The Cisco uBR924 cable modem is able to obtain two types of keys from the CMTS:

Traffic Exchange Key (TEK), used to encrypt and decrypt data packets

Key Exchange Key (KEK), used to decrypt the TEK



Good Luck M8!!
