Information about Multiple Cores
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.
Restrictions for Multiple Cores Configuration
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.
How to Configure Multiple Cores
This section describes how to configure multiple cores on Cisco cBR-8.
Configuring Multiple Cores
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*/
