Configuring Trust and Validity for Manufacturer Certificates

A Certificate Authority (CA) is a self-signed certificate containing the DOCSIS
CA’s trusted public key. The manufacturer issues an X.509 certificate that
binds the cable modem public key to other identifying information. BPI+ uses
the X.509 digital certificate to authenticate key exchanges between the
cable modem and CMTS.

You can configure and display trust for all new self-assigned manufacturer
certificates, as well as for existing certificates for a specified cable modem. In
addition you can configure certificates to have or not to have their validity
period checked against the current time of day. Note that this task applies to
BPI+ only.

Configuring trust and validity for certificates involves setting the following
parameters:
