Troubleshooting Device Issues

Device check aims to identify, diagnose, and debug issues on your device. The Device Check tab in the Tools 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 Device Output section.

To perform a device check on a switch, complete the following steps:

1. In the Network Operations 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 Groups, Labels, or Sites. For all devices, set the filter to Global.

     The dashboard context for the selected filter is displayed.

   • To select a device in the filter:
     1. Set the filter to Global.
     2. Under Manage, click Devices > Switches.
     3. A list of devices is displayed in the List view.
     4. Click a switch listed under Device Name for which you want to perform diagnostic test.

     The dashboard context for the switch is displayed.

2. Under Analyze, click Tools. The Tools page opens.
3. Click the Device Check tab.
   • By default, the Device Type is set to Switch 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 Switch 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 a AOS-Switch only from version 16.05.000 or above.
     • Cable Test is not supported in AOS-CX switch.
   • 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 Cable Test, PoE Bounce, or Interface Bounce, you must enter the port number or the port number range as mentioned in the example text.
     • If you navigate to the Tools page from the Clients page, under Device Check 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.
6. Click Run.

   The output is displayed in the Device Output section.

Important Points to Note

• Interface Bounce, PoE Bounce, and Chassis Locate tests are supported only from the following versions in switches:
• AOS-Switch: See Supported AOS-Switch Platforms.
• AOS-CX: See Supported AOS-CX Switch Platforms.

Viewing the Device Output

After you execute troubleshooting commands on the devices, Aruba Central displays the output in the Device Output section of the Tools 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.

You can perform the following tasks from the Device Output section:

• Click Clear to clear the output. You can clear the output for a single device or for all devices. The Clear option is disabled for read-only users.
• Click the search icon to search for text in the output.
• Click the email icon and click Send to send the output as an email. You can also add email recipients in the CC field.
• Click the export 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.
