The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Information About GCPP Support
The Generic Control Protocol (GCP) sets up a control plane tunnel over a generic transport protocol such as TCP or UDP. GCP
is used to program the remote PHY system upstream and downstream parameters from the CMTS. It is also used to control the
remote PHY system.
The Remote PHY architecture with GCPP (Generic Control Protocol Principal) server, includes separate DOCSIS, QAM video and
OOB cores. To enable the use of multiple RPHY cores, the architecture utilizes a GCP Principal Core (GCPP). Initially, the
RPDs contact and authenticate with the GCPP core, which also configures the RPDs in its domain in coordination with the Cores
(DOCSIS, QAM video, and OOB).
Without the GCPP core, cBR8 is the principal core for RPD. However, in this GCPP architecture, the GCPP server is the principal
core and the Cisco cBR8 is an auxiliary core.
GCPP Core
GCPP core provides containerized services for automating deployments, managing applications, the initial authentication of
the RPDs, and configuring RPD features and video services. The Principal Core does not provide any services (video or data).
The GCPP configures RPDs using GCP with the details of the other Cores that will configure it and the resources that will
be configured by those Cores. The GCPP then performs the RPD operational configuration and the video and OOB service configuration.
By the end of this process, the RPD will have its operational configuration and video and OOB services set up.
The GCPP core performs the following three primary functions:
Initial authentication of the RPD
Initial configuration of the RPD, including the list of cores to which it connects and the resources that those other cores
will configure
Configuration of the multicast sources that the RPD uses to populate QAM video (broadcast and narrowcast) channels
GCPP allows integrating videos on a standardized, single video platform. It also provides the configuration of the RPD's video
channels, removing the requirements from the Video Core to support RPD authentication and GCP configuration.
How to Configure GCPP Core
This section contains the following:
Adding GCPP Core IP Address
Add the GCPP core IP address in the original CNR RPD policy if your RPD helper address is cnr8/auto-cnr. Or add the DHCP pool
with the GCPP core/CCAP core in the USD.
Configuring Cisco cBR for Enabling GCPP
To set the GCPP server as the core server, configure Cisco cBR to remove the principal keyword under RPD configuration.
