Important:Cisco Smart PHY does not allow you to configure a VSG on a Downstream Port 1 (ds1) with broadcast keyword through the Cisco cBR-8 CLI. If you try to configure a VSG on a Downstream Port 1 (ds1) with broadcast keyword, then the CLI shows an error.Cisco Smart PHY maps a VSG to a video interface based on the order of the VSGs and interfaces if a VSG can map to more than one interface:

  • A VSG can map to more than one video interface if the video interface list includes both ports 0 and 2 or both ports 4 and 6 of one Cisco cBR-8 Series 8x10G Remote PHY Digital Physical Interface Card (CBR-DPIC-8X10G).

  • Cisco Smart PHY maps the first VSG to a matching Principal Core interface if present; otherwise, it maps the first VSG to the first matching video interface.

  • Cisco Smart PHY maps second, third, and fourth VSGs to the highest numbered matching video interfaces.

Cisco Smart PHY reorders video interfaces and VSGs, so that a video interface that matches the Principal Core interface and the associated VSGs are listed first.
RF Parameters
Base Power (dBmV) Configure the base channel power level. Enter the value based on the type of RPD.

  • Node RPDs: 20-22

Viewing and Editing Service Definitions

Once you create a Service Definition, you can view and edit it anytime. You can view the Service Definition information after a service is created and associated with the RPDs.

  • You can view the Service Definition information after a service is created and associated with the RPDs. For more information, see Viewing Service Definitions.

  • You can dynamically edit the parameters of a Service Definition including its name even when the RPDs are associated to service definitions. For more information, see Editing Service Definitions.

Viewing Service Definitions

The procedure enables you to view service definition details in the Service Definitions page.

Procedure
  Command or Action Purpose
Step 1

At the main menu, click Smart PHY > Service Definitions.

The Service Definitions page appears.

Step 2

Click any Service Definition to view the following details:

Table 5. Service Definition Fields
Field Name Details
Overview Displays the overview of the Service Definition and contains the version, description, tags, create time, last modification details, and RPDs Assigned.
Configurations Displays the details of the various configuration parameters that are used in the Service Definition.
Assigned RPDs Displays the list of RPDs assigned to that Service Definition.
Version History Displays the history of the changes for a Service Definition in chronological order.

Editing Service Definitions

You can dynamically edit the parameters of a Service Definition including its name even when the RPDs are associated to service definitions. You can then apply the changes to one or more RPDs that are already running that specific service definition. If a Service Definition is edited, then its version gets updated and is visible in the Service Definition page.

Editing a Service Definition may affect the service particularly, when you want to apply the changes to RPDs. On the Smart PHY UI, if a flag is visible next to a Service Definition parameter, it signifies that it is a service impacting field. You may get config push error from the Cisco cBR-8 router and may have to reprovision the RPD. However, if you don't want to reprovision the RPDs, you can use the updated service definition parameters to provision new RPDs in the network. For more details, see Service Definitions.

Also, if the Cisco cBR-8 router is in maintenance mode, you cannot propagate these changes to the RPDs. In these scenarios, configuration error messages appear in the RPD 360 page.

This procedure edits a Service Definition.

Provisioning an RPD for Video Support

Table 6. Feature History

Feature Name

Release Information

Description

Multi Core Atomic Provisioning

Cisco Smart PHY, Release 22.2

  • Atomic transactions when multiple cores are involved.

  • Automatic rollback on transaction failure.

Cisco Smart PHY can be configured to use distinct Cisco cBR-8 routers as the DOCSIS Principal core and auxiliary video core.

The DOCSIS configuration is pushed to the Principal core and the video configuration is pushed to the specified Video Auxiliary core. You can configure the OOB core to be either the Principal core or the Video Auxiliary core. The OOB 55–1 and NDF/NDR configurations are pushed to the OOB core through the OOB core interface. You can configure only the Pilot tone, SSD, and DLM on the Principal core.


Important

When integrating Viavi with RPD, NDF or NDR must be configured on the Principal Core. Viavi communicates with the core using SNMP MIBs that are only available on the Principal Core.

Cisco Smart PHY can also provision an RPD for supporting video using a standalone Cisco cBR-8 router or some other Core that is not managed by Cisco Smart PHY, as the Principal core.

If the principal core is not managed by Cisco Smart PHY and you do not have OOB 55–1 configuration on the auxiliary video core, the RPD Assignment does not require Service Definition configuration.


Note

  • When you provision data and video services on two different cores simultaneously, Smart PHY considers it as an atomic transaction. In other words, an RPD is provisioned successfully when both data and video services are configured successfully. If the configuration of either core fails, then the entire operation is rolled back.

  • When you provision data and video services on different cores at different point of time, each provisioning operation is considered as an independent transaction.

    • If RPD is online with both Principal Core and separate Video Auxiliary Core, and you remove the Video Core configuration, the RPD reboots and becomes online with only the Principal Core.

    • If the RPD is online with only the Principal Core, and later if you configure a separate Video Auxiliary Core, the RPD does not reboot automatically. You must manually reboot the RPD to get it to redirect to the new Video Core. After the RPD reboots, it becomes online with both cores.


Caution

When you use the REST API to provision an RPD with separate video cores, you must use only version 2 (V2) RPD-pairing REST API. If you use V1 RPD-pairing API to provision an RPD with separate video cores, it may lead to data corruption. Also, version 1 (V1) of the RPD-pairing REST API does not support features such as 1x2 node segmentation, 2x2 node segmentation, OOB override, DLM, or separate video cores.

Common OOB 55-1 US Profile for Cisco RPD 1x2/2x2

The Cisco cBR-8 router supports configuring the same profile to both upstream physical RF ports in an RPD. Service providers can expand the OOB 55–1 service group on to the second US port without the need for extra hardware.

This feature is available only in the following versions of Cisco cBR-8 series routers:

  • Cisco IOS XE Fuji 16.8.1 and earlier

  • Cisco IOS XE Amsterdam 17.3.1x and later


Note

When you provision data and OOB services on two different cores, Smart PHY considers it as an atomic transaction.

Configuring Video Services

You can configure video service in a Cisco cBR-8 router using Cisco Smart PHY by wiring the video interfaces and video service groups (VSG).

Cisco Smart PHY provides a clear mapping between VSG and video interfaces. RPD node segmentation determines the number of VSGs that you can choose for a video interface.

Prerequisites

Create video service groups (VSG) in the Cisco cBR-8 router, before you configure a video service for each RPD. There are two ways to create VSGs:

  • Manual method(Recommended): Provide a logical name for the VSG. Example: cable virtual-service-group 18528 downstream-video 1/0/8 profile 101

  • Automatic method: When you assign a controller to a Cisco cBR-8 router profile that has video services, Cisco cBR-8 creates a VSG with a random name.

For more details, see Cisco Converged Broadband Routers Video Configuration Guide for Cisco IOS XE Bengaluru 17.6.x.

Adding a New Video Interface

Use the following task to add a new video interface.

  1. Click the main menu at the top-left of the home page, and select > Smart PHY > RPD Associations. The Remote PHY Device Associations page displays.

  2. Click the Create button. The Create Remote PHY Device Association page displays.

  3. Add single or multiple entries in the Video Core Interface and Video Service Group fields.

  4. Click the Save button.

You can also import CSV files from the previous versions of the Cisco Smart PHY application which have video configurations. You can also import a database that is exported from a previous version of the Cisco Smart PHY application.

Configuring VSG Using API

You can configure VSG using the Cisco Smart PHY API setrpdpairinglist.

This API is backward compatible. It has an extra videointerfaces field under port-config. The existing video service group mapping with the video interfaces, remains without any changes.

           ]
        }
      ]
    }
  ]
}

Limitations

  • If you use the setrpdpairinglist API without the videoInterfaces attribute under port-configs, Cisco SmartPHY performs an ambiguity resolution. This process does not provide a clear one-to-one mapping.

  • If two or more VSGs are configured under the same interface, the videointerfaces must repeat to match the one-to-one mapping.

  • If you do not add the video interfaces under port-config and the assigned-cores, then the application shows an error.

  • The size of the list of video interfaces and the VSGs must be the same.

  • You can only map a VSG to a single interface. However, you can map the VSG to the same interface in a different port.

  • If you configure a video interface without mapping to a VSG, then the application ignores the video interface.

cBR-8 Configuration Reconciliation

Feature History

Feature Name Release information Description
cBR-8 Configuration Reconciliation Cisco Smart PHY 22.2 You can now detect the configuration mismatches between the cBR-8 router and Smart PHY cluster. This helps in reconciling the configuration between both the entities so that the configuration set are in sync with each other and eliminates the need of reprovisioning of RPDs effectively and saves time.

Post upgrading the software on CBR-8 router, the CBR-8 software automatically converts its earlier CLI configuration syntax into a new form on the CBR-CCAP-LC-G2-R line card. Ambiguity and differences may be seen between the actual configuration in the cBR-8 router and the corresponding configuration that is stored in the Smart PHY cluster.

The Smart PHY reconciliation feature intelligently detects such configuration mismatches and updates its internal configuration. This reconciliation helps in maintaining the cBR-8 and Smart PHY configuration to be in sync and avoids reprovisioning of RPDs. During such reconciliation process, which can be triggered when cBR-8 transitions from maintenance to normal mode, Smart PHY takes care of the following aspects:

  1. Detects the configuration differences and prepares a report of the configuration difference between cBR-8 and Smart PHY.

  2. Updates the Resource Allocation information and CLI details in Smart PHY when there is any discrepancy.

  3. Ensures that existing RPDs are not reprovisioned and the new RPDs use the correct set of resources.


Note

In Smart PHY, the reconciliation feature assumes that the RPDs are configured with the same name in both Smart PHY and the cBR-8 router.

Performing Smart PHY Reconciliation Operation

To perform reconciliation operation from the UI, perform the following steps:

  1. At the main menu, click Smart PHY > Inventory. The Remote PHY Devices & CCAP Cores page displays.

  2. Select the check boxes of one or more cBR-8 routers that are in the maintenance mode.

  3. From the Managed CCAP Actions drop-down list, click Resume Maintenance Mode.

  4. Review the Warning message, select the Reconcile cBR-8 configuration check box. The reconciliation operation takes place. The CCAP core is moved out of the maintenance state and reconciliation is performed.

  5. Click Resume Normal Operation.

Managing RF Power Adjust Profiles

Feature History

Feature Name Release information Description

RF Power Adjust Profile Enhancement

Cisco Smart PHY, Release 22.2

You can overwrite the RF Power Adjust Profile during RPD provisioning.

Smart PHY allows you to adjust the power levels for a single or a group of downstream RF channels using an RF Power Adjust Profile. An RF Power Adjust Profile consists of a profile name, an RF channel identifier (or identifiers), and a power adjust value. You can manage RF Power Adjust Profiles from Smart PHY's RF Power Adjust Profiles page.

RF channel power adjustment does not affect the service of the RPDs.

Limitations for RF Power Adjust Profile

  • You cannot delete an RF Power Adjust Profile that is already used in a Service Definition.

  • If you modify an RF Profile, the updated configuration is not applied to the RPDs that have already been provisioned. You can access the appropriate Service Definition page, select Save & Assign, select the specific RPD, and click Assign to apply the modified RF Power Adjust Profile parameters.

Creating an RF Power Adjust Profile

This procedure creates an RF power adjust profile.
