Information About cBR-8 as Auxiliary Video Core
The Cisco cBR-8 supports both Generic Control Protocol (GCP) and Downstream External PHY Interface (DEPI) control and data planes. From Cisco IOS XE Amsterdam 17.3.1w release, you can configure a Cisco cBR-8 as an Remote PHY Auxiliary Video Core. Use the Cisco cBR-8 as an Auxiliary Video Core to support video and OOB with a Cisco cnBR or to support video on a separate Cisco cBR-8 other than the DOCSIS core.
This feature allows configuring a Cisco cBR-8 as an auxiliary video core without having DOCSIS configuration on the same Cisco cBR-8. The auxiliary video core, the DOCSIS core, and the principal core interface separately with RPDs.
Limitations
When you configure separate Cisco cBR-8s as DOCSIS and video cores, you must avoid RF channel reuse. A combined cBR-8 DOCSIS and Video Core ensures that RF channel reuse does not occur. Error detection occurs only when an RPD receives the configuration.
