Troubleshooting Device Issues
Device check aims to identify, diagnose, and debug issues on your device. The tab in the page can be used to perform troubleshooting check for Aruba Switches only. When a troubleshooting operation is initiated, Aruba Central establishes a session with the Switch selected for the troubleshooting operation and displays the output in the section.
To perform a device check on a switch, complete the following steps:
1. In the app, select one of the following options:
To select a group, label, site, or all devices in the filter, set the filter to one of the options under , , or . For all devices, set the filter to .
The dashboard context for the selected filter is displayed.
To select a device in the filter:
a. Set the filter to .
b. Under , click > .
A list of devices is displayed in the view.
c. Click a switch listed under for which you want to perform diagnostic test.
The dashboard context for the switch is displayed.
2. Under , click . The page opens.
3. Click the tab.

By default, the is set to if a switch is configured in the data path, else a warning is displayed. Multiple device selection is not allowed at this level. Devices which are already running commands shall not execute newly added commands. |
4. From the drop-down list, select the switch.
5. Select one of the following tests to perform diagnostic checks on the selected switch:
Cable Test—Enables testing of the electrical connections in the switch cable. It checks whether the cabling is conformed to the cabling plans and is of expected quantity. It is useful for production and maintenance.

|
Cable Test is supported in Aruba Switches only from version 16.05.000 or above. Cable Test is not supported in Aruba CX switches. |
Interface Bounce—Restarts the port interface and forces a client to re-initiate a DHCPDynamic 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 Aruba Switches.
PoEPower over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port. 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 Aruba Switches.

If you select , , or , you must enter the port number or the port number range as mentioned in the example text. If you navigate to the page from the page, under the client context is already set and the port number is auto filled based on the client selected. |
Chassis Locate—Activates the Switch locator LEDLight 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.
Important Points to Note
|
|
Interface Bounce, PoE Bounce, and Chassis Locate tests are supported only from the following versions in switches: Aruba Switches: See Supported Switch Platforms. Aruba CX: See Supported Aruba CX Switch Platforms. |
6. Click . The output is displayed in the section.
Viewing the Device Output
After you execute troubleshooting commands on the devices, Aruba Central displays the output in the section of the page.
The output pane displays a list of devices on which the troubleshooting commands were executed, the test type, initial timestamp, source, and argument. It also shows the status of the tests as, in progress, complete, and the buffer time.
|
|
Output history of device with buffer space issues shall be automatically cleared. |
You can perform the following tasks from the section:
Click to clear the output. You can clear the output for a single device or for all devices. The option is disabled for read-only users.
Click the icon to search for text in the output.
Click the icon and click to send the output as an email. You can also add email recipients in the field.
Click the to export the command output as a zip file.
Click the maximize icon to maximize the device output pane.
Unlike the other tests, for Cable Test, the output is displayed in a tabular format, and you cannot download, email, or export the output.
