Usage Guidelines Baseline privacy key management exchanges take place only when both the router and the CMTS are
running code images that support Baseline Privacy Interface (BPI) or BPI Plus (BPI+) encryption, and
the privacy class of service is enabled via the configuration file that is downloaded to the router. Baseline
privacy code images for the router contain k1, k8, or k9 in the code image name.
Examples The following shows typical output for the show controllers cable-modem bpkm command for
DOCSIS 1.0 BPI operation when the CMTS does not have baseline privacy enabled:
