Usage Guidelines

Baseline privacy key management exchanges take place only when both the Cisco uBR900 series 
and the CMTS are running code images that support baseline privacy, and the privacy class of service 
is enabled via the configuration file that is downloaded to the cable access router. Baseline privacy 
code images for the Cisco uBR900 series contain k1 in the code image name.

Examples

The following example shows debug output when the headend does not have privacy enabled:
