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. Learn more about how Cisco is using Inclusive Language.
This document describes the multiple cores in the Remote PHY system.
Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Note | The hardware components introduced in a given Cisco Remote PHY Device Software Release are supported in all subsequent releases unless otherwise specified. |
The RPD can be managed by more than one CCAP core. An RPD is controlled by exactly one principal CCAP core and zero or more auxiliary CCAP core(s). Each CCAP core manages a subset of RPD resources, e.g., particular channels or RF ports.
Principal core is responsible for the configuration of common parameters for the RPD and for certain device management functions. Principal core can provide DOCSIS, video or OOB service. Auxiliary cores are responsible for providing video or OOB services. They are restricted to the resource set assigned to them by the principal core.
The following restrictions are applicable to mutiple cores configuration:
Maximum four cores are supported.
DOCSIS controllers can only be configured to principal core, while video controllers can be configured to all cores.
Only one core can be principal, the rest will be auxiliary.
Principal core needs to be configured explicitly.
At least one DOCSIS downstream controller and one upstream controller are needed for principal core.
No upstream controller for auxiliary core and at least one downstream controller is needed for auxiliary core.
Only single CMTS is supported.
No downstram frequency and channel id overlap is allowed for all the cores.
This section describes how to configure multiple cores on Cisco cBR-8.
To configure the multiple cores, follow the example below:
Router(config)# cable rpd sjc_block22 /* unique name for each rpd */ Router(config-rpd)# description rpd for sjc block 22 Router(config-rpd)# identifier 1122.3344.5566 /* unique id for each rpd.*/ Router(config-rpd)# rpd-ds 0 power-level 5 /* DS max-carrier and power-level info */ Router(config-rpd)# rpd-ds 0 dedicated-cw-tone cw1 /* DS pilot tone info */ Router(config-rpd)# core-interface Te3/1/0 /* Core side interface (D-PIC interface) for services below */ Router(config-rpd-core)# principal /* Specify the principal core */ Router(config-rpd-core)# rpd-ds 0 controller downstream-cable 3/0/0 profile 100 /* DS docsis channel config*/ Router(config-rpd-core)# rpd-ds 0 controller downstream-cable 3/0/1 profile 200 /* DS docsis channel config*/ Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/2 profile 300 /* DS video channel config*/ Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/3 profile 400 /* DS video channel config*/ Router(config-rpd-core)# rpd-us 0 upstream-cable 3/0/0 profile 101 /* US 0 docsis channel config*/ Router(config-rpd-core)# rpd-us 1 upstream-cable 3/0/1 profile 101 /* US 1 docsis channel config*/ Router(config-rpd-core)# depi depi_rpd_block22 /* RPD DEPI configuration.*/ Router(config-rpd-core)# exit Router(config-rpd)# core-interface Te9/1/1 /* Support multiple core-interface for cases such as video is using separate LC*/ Router(config-rpd-core)# rpd-ds 0 downstream-cable 9/0/1 profile 200 /* DS video channel config*/ Router(config-rpd-core)# depi depi_rpd_block22 /* RPD DEPI configuration.*/ Router(config-rpd-core)# exit Router(config-rpd)# r-dti 1 Router(config-rpd)# rpd-event profile 0
To display the information of the principal and auxiliary cores, use the show cable rpd command as shown in the example below:
Router# show cable rpd
