docsBpi2Ext31CodeUpdateCvcChain
Module: DOCS-BPI2EXT-MIB
OID (symbolic): DOCS-BPI2EXT-MIB::docsBpi2Ext31CodeUpdateCvcChain
OID (numeric): 1.3.6.1.4.1.4491.2.1.29.1.2.1
Node type: OBJECT-TYPE
Type: DocsCvcCaCertificateChain
Access: read-write
Description: The value of this object is a degenerate PKCS7 signedData structure that contains the CVC and the CVC CA certificate chain in the certificates field. Setting this object triggers the device to verify the CVC and update the cvcAccessStart values associated with the new PKI defined by DOCSIS 3.1. The content of this object is then discarded. If the device is not enabled to upgrade codefiles, or if the CVC verification fails, the CVC will be rejected. Reading this object always returns the zero-length OCTET STRING.
What is docsBpi2Ext31CodeUpdateCvcChain?
This object accepts a PKCS7 signedData structure containing a Code Verification Certificate (CVC) and its CA certificate chain, used when pushing a firmware update under the new DOCSIS 3.1 PKI. Setting it triggers the cable modem to validate the CVC and, if the device is enabled for code upgrades and validation succeeds, update its cvcAccessStart values; a failed check causes the CVC to be rejected, and the object always reads back as a zero-length string. For example, a firmware management system writes the signed CVC chain here as part of pushing a new code image to the modem.
