Managing Controllers
This section covers the following topics:
Aruba Central (on-premises) offers monitoring service for WLANWireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. networks configured and managed using ArubaMobility Controllers.
Aruba Central (on-premises) allows you to onboard and monitor controller clusters, the Mobility Master setup, and the master and local controller setup.
When you add a master controller or a Mobility Master, Aruba Central (on-premises) discovers all the associated controllers and campus APsCampus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on., and adds them to the device inventory.

Aruba Central (on-premises) does not support configuring controllers. To configure and deploy controllers, use the ArubaOS WebUI and CLI. Aruba Central (on-premises) does not support wired clients on a controller. |
Before You Begin
Before adding controllers to Aruba Central (on-premises), ensure that the controller has the following parameters configured:
Management Server profile—The Aruba Central (on-premises) server must be configured as a management server on the controller.
Advanced Monitoring Messages—Enable AMONAdvanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. for communication between the Aruba Central (on-premises) server and controller. When AMON is enabled on the controller over UDPUser Datagram Protocol. UDP is a part of the TCP/IP family of protocols used for data transfer. UDP is typically used for streaming media. UDP is a stateless protocol, which means it does not acknowledge that the packets being sent have been received. 8211, the controller periodically sends information about user sessions, AP and client association, and other such information required for managing and monitoring controllers on Aruba Central (on-premises).
Syslog Messages and SNMPSimple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. Traps—Although AMON is a preferred option for polling data from controllers, to obtain data pertaining to AP lists, you may want to enable SNMP, and configure SNMP traps and syslog server for logging system events.
Websocket connection—To enable controller firmware upgrade and troubleshooting from Aruba Central (on-premises), ensure that the Aruba Central (on-premises) server URLUniform Resource Locator. URL is a global address used for locating web resources on the Internet. and IP address are configured on the controllers running ArubaOS 6.5.3.6 or later.
For more information on configuring controllers, see ArubaOS User Guide.

Tools support is available for controllers that support web socket. For example, controllers running Firmware version above 8.4.x or 6.5.x. Controllers running ArubaOS 6.5.4.8 software image do not support Websocket connection, due to which Aruba Central (on-premises) cannot onboard these controllers. |
