Editing a controller

To edit a controller:

1. In the menu, go to the Infrastructure section.

   This opens the resource management page. By default, the Network resources tab is selected, which displays the table of controllers.

2. Click Management → Edit next to the controller that you want to edit.
3. This opens a window; in that window, in the Name field, enter the name of the controller. Range of values: 1 to 128 characters.
4. If necessary, in the Description field, enter a brief description of the controller.
5. In the Controller installation on <1>/<3>/<5> servers field, select the number of controller nodes.
6. In the Connection type drop-down list, select the type of connection of CPE devices to the controller:
   • Unicast
   • Multicast
7. Configure the controller node:
   1. In the IP address or hostname field, enter the IP address or hostname of the controller node.
   2. In the gRPC port field, enter the gRPC port number of the controller node.
   3. In the JGroups port field, enter the jGroups port number of the controller node.
   4. If you want to make the controller node the primary node, select the Primary option.

   You can configure multiple controller nodes.

8. If you want to change how the load is distributed between nodes in the controller cluster when reading data, in the gRPC read load balancing mode drop-down list, select a balancing mode:
   • Primary Node Only.

     Read operations are performed exclusively through the primary cluster node.

   • Prioritize random secondary node.

     Read operations are performed with priority given to a randomly chosen secondary cluster node.

   • Select Manually.

     Read operations are performed through an explicitly specified prioritized cluster node.

   If you select the Select Manually mode, in the Selected node list that appears, select the priority node through which you want read operations to be performed.

9. Click Save.

The controller is modified and updated in the table.
