External Interfaces Support for Cisco Cloud Native Broadband Router

Cisco cnBR supports legacy interface translation, general network management, and monitoring information.

Cisco cnBR supports the following external interfaces:

IP Detail Record Service

The Cisco Operations Hub hosted IP Detail Record (IPDR) service provides the mechanisms to export IP detailed records to IPDR collectors and the ability to configure the IPDR service.

IPDR Service

The Cisco Operations Hub IPDR service operates in a similar way as other Cisco Cable Modem Termination Systems (CMTS) products. You can configure it through the REST interface. See IPDR Streaming Protocol on the Cisco CMTS Routers for reference.

The URL https://{Hostname}/api/ipdr is created for the IPDR service, which is used for the REST configuration and status requests. The collector connects to the IPDR service on default port 4737 to establish a TCP session. Then, IPDR records are streamed from the IPDR service to the collector over this TCP session.

For the IPDR service to deliver records, the IP address of the collector that receives the records is required. An ordered list of collectors is contained in a session. Only one collector in a session receives the records, the others are available as backup. The session describes the delivery mechanism and record format. You can define multiple sessions so that more than one collector can receive IPDR records from Operations Hub.

Terminology

This table lists and describes the IPDR terminology.

Term Description
Collector The host that receives (collects) the IPDR records.
Exporter The IPDR service includes an exporter service that generates the IPDR records.
Session Describes the set of collectors and templates that are used to send IPDR records. At a time, only one collector in a session gets IPDR data at a time based on a priority order. If a collector is unavailable, the collector with the next highest priority gets the records.
Template Identifies the record format for sending the records.

Configure IPDR Service

To configure the IPDR service, use a single command to set all configuration parameters in JSON format in one single action. This configuration method overwrites the existing configuration and activates the new configuration.

/v1/config


Note

/ipdr/config is deprecated but usable.


To set the configuration, use the PUT HTTP method as shown in the following example.

curl -k -X PUT -H "Content-Type: application/json" -d @- << EOF https://{Hostname}/api/ipdr/v1/config
{json_string}
EOF

Note

Parameter -k allows insecure server connections when using SSL.


Example: Add or change IPDR configuration.

curl -k -X PUT -H "Content-Type: application/json" -d @- << EOF https://opshub1.cisco.com/api/ipdr/v1/config

REST Return Codes

You can use the status codes listed in the following table to convey the results of a request.

This table lists the REST Return codes, descriptions, response text, and actions.

Code Short Description Response Text Actions
400 HTTP_BAD_REQUEST
  • Failure: request format error.

  • Failed to configure session when exporter starts, stop it at first.

Confirm that the format of the request is valid or restart the IPDR service to apply new sessions.
404 HTTP_NOT_FOUND
  • Failure: collector doesn't exist.

Return this code when adding a session referring to a collector that does not exist. If it is a consolidated configuration request, correct the request to include a valid collector.
500 HTTP_BAD_REQUEST
  • Failed to add new session to cache.

  • Failed to apply IPDR configuration.

  • Failed to config ipdr session to exporter.

  • Failed to get ipdr sessions with internal error.

  • Failed to recover configurations.

  • Failed to remove session in cache.

  • Failed to revert session in cache when db failed.

  • Failed to update IPDR configuration.

  • Failure: allocate JSON object error.

  • Failure: get ipdr config information error.

  • Failure: not enough memory.

  • Failure: save global cfg error.

  • IPDR configuration not updated, restored to original.

Internal error that requires engineering team engagement.
503 HTTP_SER_UNAVAIL
  • not ready

Use this code only in response to readiness check. If the service is not ready, confirm that the Cassandra database is ready. Otherwise, get the database ready. If the Cassandra database is ready and operational, ask for customer support.

Simple Network Management Protocol

The Simple Network Management Protocol (SNMP) allows you to monitor the DOCSIS elements of Cisco cnBR.

The REST API is the recommended method to configure and operate Cisco cnBR. However, partial SNMP functionality is provided for compatibility with legacy SNMP applications. The Cisco cnBR SNMP Agent is located on the Cisco Operations Hub, and not on individual Cisco cnBRs.

SNMP aggregates information from multiple Cisco cnBR cores that are managed by Cisco Operations Hub.

From an application perspective, you must consider the Cisco Operations Hub as a large Cisco cnBR.

The following image provides you an overview of how the SNMP works in the Cisco cnBR.

SNMP Service

Configure SNMP

Follow these steps to configure SNMP for Cisco cnBR:

Procedure


Use the REST API to configure the SNMPv2 community string or Trap Receivers.

curl -X {GET|PUT|DELETE} https://{hostname}/api/snmp/v1/config

Use one of the following options:

  • SNMPv2 Community

    To configure SNMPv2 Community, replace <opshub-ip> with the Cisco Operations Hub IP. The following example is only indicative. See the Cisco Cloud Native Broadband Router Operations Hub REST API Guide for the authentication and encryption format.
    
    curl -X GET https://{hostname}/api/snmp/v1/config
    {"community-list":[],"v3user-list":[],"trap-receivers":[],"trap-enabled-list":[]}
    
    curl -X PUT -d @- << EOF https://{hostname}/api/snmp/v1/config
    {
      "community-list": [
        {
          "community": "public",
          "access": "ro",
          "source": "",
          "oid": ""
        }
      ]
    }
    EOF
    
    curl -X GET https://{hostname}/api/snmp/v1/config
    {"community-list":[{"community":"public","access":"ro","source":"","oid":""}],
    "v3user-list":[],"trap-receivers":[],"trap-enabled-list":[]}
    
    curl -X DELETE -d @- << EOF https://{hostname}/api/snmp/v1/config
    {
      "community-list": [
        {
          "community": "public",
          "access": "ro",
          "source": "",
          "oid": ""
        }
      ]
    }
    EOF
  • SNMPv1/v2 Trap

    The Trap Receiver is a server listening to a specific UDP port for SNMP Trap events. Use the following REST API to configure the Trap Receiver IP address, port, and other information in the Cisco cnBR SNMP agent. The REST API enables the agent to send traps to the trap receiver.
    
    curl -X PUT -d @- << EOF https://{hostname}/api/snmp/v1/config
    {
      "trap-receivers": [
        {
          "host": "10.1.1.2",
          "port": 12348,
          "version": 2,
          "community": "private"
        }
      ]
    }
    EOF
    
    curl -X GET https://{hostname}/api/snmp/v1/config
    {"community-list":[],"v3user-list":[],"trap-receivers":
    [{"host":"1.1.2.2","port":12345,"version":1,"community":"public"},
    {"host":"10.1.1.2","port":12348,"version":2,"community":"private"}]}
    
    curl -X DELETE -d @- << EOF https://{hostname}/api/snmp/v1/config
    {
      "trap-receivers": [
        {
          "host": "1.1.2.2"
        }
      ]
    }
    EOF
    
Note 
  • host: Trap Receiver's IP address. For DELETE action, host is the key, and the other fields are not necessary.

  • port: Trap Receiver listens on this port. The Trap Receiver uses the default port 162, if the port is not specified.

  • version: 1 for SNMPv1, 2 for SNMPv2.

  • community: Specify the community string to send or receive trap. At the receiver side, there is a configuration file to specify the community.
