Set Up CV-CUE on CV

This section describes the process to:

Setup CV-CUE on a Standalone CV

CV-CUE is disabled by default.

To enable CV-CUE, perform the following steps:

Log in to the CV admin shell via the cvpadmin user.
Enter e to edit the settings. The CV configuration wizard is launched.

Note: If you are setting up CV for the first time, you need to enter the values for all the settings (DNS, IP addresses, etc.) in the configuration wizard. Refer to the Shell-based Configuration for information on these settings. If you have already set up or just upgraded CV, and you only want to enable CV-CUE, go to Step 3.
Set the CV-CUE Enabled option to Yes.
Once the cursor is at the bottom of the configuration wizard, enter a to apply the configuration changes.

A few important points about the CV-CUE service in a cluster deployment:

CV-CUE is disabled by default.
For a CV cluster, you first need to Enable CV-CUE on Primary Node and then Set Up CV-CUE on Secondary and Tertiary Nodes .
Note: The CV-CUE service runs only on the primary and secondary nodes, but you need to apply the configuration changes to all the nodes, including the tertiary node. The CV-CUE service starts on both nodes only after the setup on all the nodes (including the tertiary node) of the cluster has been completed.
The CV configuration wizard consists of two parts (Enable CV-CUE on Primary Node ):
- common configuration: Settings common to all the nodes in the cluster (For example, DNS and services such as CV-CUE).
- node configuration: Settings specific to a node (For example, Hostname and IP settings).

To enable CV-CUE on the primary node, perform the following steps:

Log in to the CV admin shell via the cvpadmin user.
Enter e to edit the settings. The CV configuration wizard is launched.

Note: If you are setting up CV for the first time, you need to enter the values for all the settings (those belonging to the common configuration as well as the node configuration). Refer to Shell-based Configuration and Shell Reconfiguration of Single-node, Multi-node Systems for information on these settings. If you have already set up or just upgraded CV, and you only want to enable CV-CUE, go to Step 3.
You can optionally assign a CV-CUE HA Cluster IP.

Note: CV-CUE in HA mode configures an optional IP address, known as HA cluster IP that is automatically assigned to the active node in a cluster. Ensure that the HA Cluster IP address is different from the IP addresses of the actual device and cluster interfaces; but belongs to the same subnet as the Device Interface IP addresses of primary and secondary nodes. If HA cluster IP is not configured, IP addresses of both primary and secondary nodes must be configured on access points.
Set the CV-CUE Enabled option to Yes.

To set up CV-CUE on the secondary and tertiary nodes, perform the following steps on the respective nodes:

Log in to the CV admin shell via the cvpadmin user.
Enter e to edit the settings. The CV configuration wizard is launched.

Note: The Shell-based Configuration settings are not editable on the secondary and tertiary nodes. If you are setting up CV for the first time, you need to enter the values for all the Shell Reconfiguration of Single-node, Multi-node Systems settings. If you have already set up or just upgraded CV, and you only want to enable CV-CUE, go to Step 3.
Press Enter until the cursor reaches the bottom of the configuration wizard, past all the settings.
Once the cursor is at the bottom of the configuration wizard, enter a to apply the configuration changes.

Note: Whether CV-CUE Enabled is set to Yes or No, applying the configuration changes causes the secondary and tertiary nodes to update their settings based on the primary node. This will start the CV-CUE service on the primary and secondary nodes.
