Using Troubleshooting Tools

The Troubleshooting menu in the Maintenance module allows your network administrators to run troubleshooting or diagnostics commands on the devices managed from HPE Aruba Networking Central. When a troubleshooting operation is initiated, HPE Aruba Networking Central establishes a session with the devices, retrieves the output of the commands, and displays the output in the UI User Interface. .

HPE Aruba Networking Central supports running troubleshooting operations on one or several devices. You can select up to 10 devices for a troubleshooting operation. If the user access is restricted to certain groups within a network, HPE Aruba Networking Central allows running troubleshooting commands only for the devices provisioned in the allowed groups.

Troubleshooting a Device

To run troubleshooting commands on the devices, complete the following steps:

From the app Short form for application. It generally refers to the application that is downloaded and used on mobile devices. selector, click Maintenance > Troubleshooting. The Troubleshooting page opens.
Select a device category.
- To troubleshoot an AP, click the Access Points tab.
- To troubleshoot a switch, click the Switches tab.
- To troubleshoot a controller, click the Controllers tab.
Select the devices for which you want to run diagnostic checks or troubleshooting operations. Table 1 describes the fields and filtering parameters available on the Troubleshooting page:

Table 1: Contents of the Troubleshooting Page
Data Pane Item	Description
Access Points	Allows you to run troubleshooting commands on Instant APs. To run diagnostic checks, select the Instant APs from the AP Name drop-down.
Switches	Allows you to run the troubleshooting commands on a Switch. To run diagnostic checks, select the Switches from the Switch Name drop-down.
Controllers	Allows you to run troubleshooting commands on controllers. To run diagnostic checks, select the controller from Controller-Name drop-down.
Troubleshooting	Allows you to select one of the following options: Tools—Provides a list of basic troubleshooting tools to verify network connectivity and latency issues. Commands—Allows you to select a specific set of CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands to run on the selected devices for diagnostics and troubleshooting purposes.
Tools	Allows you to run the following diagnostic tools on the selected devices: Ping—Sends ICMP Internet Control Message Protocol. ICMP is an error reporting protocol. It is used by network devices such as routers, to send error messages and operational information to the source IP address when network problems prevent delivery of IP packets. echo packets to the IP addresses of the selected devices to check for latency issues. Traceroute—Tracks the packets routed from a network host. Speed-Test—Runs a speed test to measure network speed and bandwidth. The speed-test diagnostic tool is available only for Instant APs. For speed-test diagnosis, you must provide the Iperf server address, the protocol type, and speed-test options such as bandwidth. LED Chassislocate—Activates the Switch locator LED Light Emitting Diode. LED is a semiconductor light source that emits light when an electric current passes through it. . The locator LED indicates the physical location where an Aruba Switch is currently installed. POE Bounce—Restarts the PoE port and the device that is either connected to the PoE port or powered by it. This option is available only for the HPE Aruba Networking switches. Interface Bounce—Restarts the port interface and forces a client to re-initiate a DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network. request. This option is available only for the HPE Aruba Networking switches.
Commands	Category—Allows you to select a category. The troubleshooting commands are segregated under the following categories: Access Points Wireless Security Network Airgroup The application that allows the end users to register their personal mobile devices on a local network and define a group of friends or associates who are allowed to share them. AirGroup is primarily designed for colleges and other institutions. AirGroup uses zero configuration networking to allow Apple mobile devices, such as the AirPrint wireless printer service and the AirPlay mirroring service, to communicate over a complex access network topology. System ARM Adaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support a maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment.
