Cluster

The Cluster dashboard provides a visual overview on each cluster deployed on the network, displaying the following information:

  • Total AP load per cluster
  • Total Client load per cluster
  • Status of each controller and access point in a cluster
  • Health of each cluster

Traditionally, cluster dashboard was visible only on the managed network. However, starting from ArubaOS 8.7.0.0, cluster dashboard can be accessed using all nodes. To view the Cluster dashboard, navigate to Dashboard > Infrastructure > Clusters in the WebUI. By default, the cluster dashboard displays the cluster with the highest AP load.

Following dashboard displays the cluster with the highest AP load. It also displays the number of active, standby and free APs for a given cluster.

To view the client load, you can select client load to display the clusters with the highest client load from the drop-down menu.

The Cluster dashboard consists of an Cluster section and Cluster Member section. Click on the AP load page or client load page to view more details.

  • Cluster > AP Load: Displays the proportional distribution and number of active, standby, and free APs. Hover your mouse above a section of the chart to view the count for that AP type:
    • Free AP Load
    • Active AP Load
    • Standby AP Load
    • Total AP Load
  • Cluster > Client Load: Displays the proportional distribution and number of active, standby, and free stations (clients). Hover your mouse above a section of the chart to view the count for that station type:
    • Free STA Load
    • Active STA Load
    • Standby STA Load
    • Total STA Load

To view in-depth information of each cluster member, click on the hyperlinked number under the Controllers column of the Clusters table. A Cluster Members pop-up window is displayed that contains a summary of each cluster member such as hostname, IP address, the cluster roles and so on. You can expand a particular cluster member to view the connection status and type (L2, L3, or both) of that cluster member as shown in the following figure:

You can click on the Controllers tab to view the status of each controller connected to the cluster. It also displays information like the software version each controller is running and the number or APs and clients attached to each controller.

Similarly, you can click on Access Devices to view the status of each AP connected to the cluster. It also displays information like Uptime, which group it belongs to, and the controller it is connected to.

Figure 5  Cluster Dashboard Access Points Information

You can also expand each controller or AP for more details on the controller or AP to view the name, IP addresses, MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. addresses, and so on.
