Information about R-PHY Video Configuration
The controller profile specifies the RF channels that belong to this profile and their RF parameters. Profile can either be unicast or multicast.
Multicast profile is used for downstream sharing. Multiple Remote PHY Devices (RPDs) can be configured to receive the same downstream controller. The traffic is multicast to all RPDs configured to receive the downstream controller. Applications include Video on Demand (VOD), Switched Digital Video (SDV) and Broadcast Video.
There is one principal core interface, and up to four auxiliary core interfaces in the RPD configuration. Principal core specifies the DPIC interface with which RPD connects. Auxiliary cores specify external DPIC interfaces that can be used for downstream sharing. Auxiliary core is currently used for narrowcast video, broadcast video and out-of-band data signaling path (OOB) only.
Line Card Redundancy
In remote PHY configuration, RPDs connect to both active linecard and standby linecard, and have active connections to active linecard, standby connections to standby linecard. From RPD side, it connects to active core and standby core independently.
Each RPD has one principal core, and may have several auxiliary cores. LCHA needs to support multiple cores. These cores are on the same linecard or different linecards. The port on the standby linecard can protect all the same ports on the active linecards.
In the figure above, the RPD has multiple cores connected to the same active linecard. In order to support LCHA, RPD needs to connect to the same port on the standby linecard. In this way, RPD has several standby cores to protect the active cores. The standby core have the same resource as the active core.
When multiple cores connect to different active linecards, if they connect to different ports of the linecard, there will have different standby cores. If active core connects to the same port on different linecard, they share one standby core.
In the figure above, RPD have two standby cores. One standby core connects to port 6 of the standby linecard, it can protect the active core which connects to port 6 of the active linecard 2. The other standby core connects to port 0 of the standby linecard, it can protect the active cores connect to port 0 of linecard 0 and linecard 1. So for the standby core 0, it contains the resource for both active core 0 and active core 1.
When active linecard 0 fails over to standby linecard, the standby core 1 will be deleted, the standby core 0 will bring the resource of active core 0 to active. When linecard 2 fails over to standby linecard, the standby core 0 will be deleted, and standby core 1 will become active for active core 3.

Supervisor Redundancy
Compared to the SUP high availability recover process in iCMTS configuration, the Remote-PHY SUP high availability recover process has RPD status change as shown in the example below:
show cable rpd 0004.9f00.0625 lcha-cores MAC Address IP Address I/F State Role HA Name 0004.9f00.0625 120.105.6.10 Te0/1/1 recovering Pri Act node1 0004.9f00.0625 120.105.6.10 Te9/1/1 recovering NA Sby node1 show cable rpd 0004.9f00.0625 lcha-cores MAC Address IP Address I/F State Role HA Name 0004.9f00.0625 120.105.6.10 Te0/1/1 init(l2tp) Pri Act node1 0004.9f00.0625 120.105.6.10 Te9/1/1 init(l2tp) NA Sby node1 show cable rpd 0004.9f00.0625 lcha-cores MAC Address IP Address I/F State Role HA Name 0004.9f00.0625 120.105.6.10 Te0/1/1 online Pri Act node1 0004.9f00.0625 120.105.6.10 Te9/1/1 online NA Sby node1
The status of the RPD changes from recovering to online, indicating that the SUP redundancy is working in the Remote-PHY configuration.

How to Configure R-PHY Video
This section describes how to configure R-PHY video on Cisco cBR-8.
- Configuring Downstream Controller Profile
- Configuring RPD
- Configuring Downstream Controller Profile
- Configuring Video
Configuring Downstream Controller Profile
To configure the donwstream controller profile, use the example below:
Router# configure terminal Router(config)# cable depi multicast pool 20 Router(config-multicast-pool)# ip address 225.28.0.0 255.255.0.0 Router(config-multicast-pool)# exit Router(config)# cable downstream controller-profile 1 Router(config-controller-profile)# multicast-pool 20 Router(config-controller-profile)# rf-chan 0 15 Router(config-prof-rf-chan)# type docsis Router(config-prof-rf-chan)# frequency 111000000 Router(config-prof-rf-chan)# rf-output normal Router(config-prof-rf-chan)# qam-profile 1 Router(config-prof-rf-chan)# docsis-channel-id 1 Router(config-prof-rf-chan)# exit Router(config-controller-profile)# rf-chan 16 19 Router(config-prof-rf-chan)# type video sync Router(config-prof-rf-chan)# frequency 699000000 Router(config-prof-rf-chan)# rf-output normal Router(config-prof-rf-chan)# qam-profile 1 Router(config-prof-rf-chan)# exit Router(config-controller-profile)# exit Router(config)# cable downstream controller-profile 2 Router(config-controller-profile)# multicast-pool 1 Router(config-controller-profile)# rf-chan 20 47 Router(config-prof-rf-chan)# type video sync Router(config-prof-rf-chan)# frequency 231000000 Router(config-prof-rf-chan)# rf-output normal Router(config-prof-rf-chan)# qam-profile 4
In the above example,two profiles are configured, profile 1 is a mixed profile, profile 2 is a video only profile.
Configuring RPD
To configure the RPD to include the controller profile, follow the example below:
Router# configure terminal Router(config)# cable rpd RPD01 Router(config-rpd)# identifier 0004.9f31.0455 Router(config-rpd)# core-interface Te3/1/0 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/0 profile 1 Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/1 profile 2 Router(config-rpd-core)# rpd-us 0 upstream-cable 3/0/0 profile 1 Router(config-rpd-core)# exit Router(config-rpd)# core-interface te6/1/0 Router(config-rpd-core)# rpd-ds 0 downstream-cable 6/0/0 profile 2 Router(config-rpd-core)# exit Router(config-rpd)# r-dti 1 Router(config-rpd)# rpd-event profile 0
Configuring Downstream Controller Profile
Downstream sharing is used for multicast (MC) traffic. To configure downstream sharing, follow the example below:
Router# configure terminal Router(config)# cable rpd RPD01 Router(config-rpd)# core-interface Te3/1/0 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/1 profile 2 Router(config-rpd-core)# exit Router(config-rpd)# exit Router(config)# cable rpd RPD02 Router(config-rpd)# core-interface te3/1/0 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/1 profile 2 Router(config-rpd-core)# exit Router(config-rpd)# exit Router(config)# cable rpd RPD03 Router(config-rpd)# core-interface te6/1/0 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 6/0/1 profile 3 Router(config-rpd-core)# exit Router(config-rpd)# core-interface te3/1/0 Router(config-rpd-core)# rpd-ds 0 downstream-cable 3/0/1 profile 2
Note | All RPDs in the same multicast group have the same controller and profile association. |
Configuring Video
To configure Video, see Cisco Converged Broadband Routers Video Configuration Guide for Cisco IOS XE Everest 16.5.1.
Example: R-PHY Video Configuration
The following example shows how to configure Remote-PHY video:
