5 Configuring NSSF using CNC Console

This chapter describes how to configure different NSSF managed objects using Oracle Communications Cloud Native Configuration Console (CNCC).

5.1 Support for Multicluster Deployment

CNC Console supports both single and multiple cluster deployments by facilitating NSSF deployment in local and remote Kubernetes clusters. For more information about single and multiple cluster deployments, see Oracle Communications Cloud Native Configuration Console Installation, Upgrade, and Fault Recovery Guide.

A single instance of CNC Console can configure multiple clusters of NSSF deployments, where each cluster has an agent console installation and a NSSF installation.

5.2 CNC Console Interface

This section provides an overview of the Oracle Communications Cloud Native Configuration Console (CNCC), which includes an interface to configure the NSSF features.

To configure the NSSF services using the CNCC, log in to the CNCC application. To log into CNCC, update the hosts file available at the C:\Windows\System32\drivers\etc location when CNCC is hosted on a third party cloud native environment.

  1. In the Windows system, open the hosts file in the notepad as an administrator and append the following set of lines at the end of the hosts file:
    <CNCC Node IP> cncc-iam-ingress-gateway.cncc.svc.cluster.local
<CNCC Node IP> cncc-core-ingress-gateway.cncc.svc.cluster.local
    For example:
    10.75.212.88 cncc-iam-ingress-gateway.cncc.svc.cluster.local
10.75.212.88 cncc-core-ingress-gateway.cncc.svc.cluster.local

    Note:

    The IP Address mentioned above may change when the deployment cluster changes.
  2. Save and close the hosts file.

    Before logging into CNC Console, create a CNCC user name and password. Log in to the CNC Console application using these login credentials. For information on creating a CNC Console user and password, see Oracle Communications Cloud Native Configuration Console Installation, Upgrade, and Fault Recovery Guide.

CNC Console Log in

Following is the procedure to log into CNC Console:

  1. Open any web browser.
  2. Enter the URL: http://<host name>:<port number>.

    where, host name is cncc-iam-ingress-ip and port number is cncc-iam-ingressport.

  3. Enter valid login credentials.
  4. Click Log in. The CNC Console interface is displayed.
