Using the AOS-S Switch Troubleshooter

HPE Aruba Networking Central offers the following tests designed to help you diagnose and fix issues related to AOS-S switch connectivity:

Ping Test

The Ping test transmits a series of ICMP echo packets to the specified destination's DNS hostname or IP address from the selected device. This quick and reliable test assesses the Latency and Packet Loss between your network and the target device, which helps to identify potential network connectivity issues.

To perform a ping test on an AOS-S switch, complete the following steps:

  1. Under Test, select the Ping radio button.

  2. In the Destination field, enter the hostname or IP address.

  3. Click Start Test.
    The Results panel on the right displays the test output.

Additional settings

Additional settings are optional, and allow the administrator to input advanced parameters to develop a precise test.

Ping test for AOS-S switches allows the following settings:

  • Loopback—Enter the Loopback port.

  • VLAN Interface—Enter the VLAN interface.

  • IP Address—Enter the IP address.

  • Packet size— Enter the packet size.

  • Count— Enter the number of probes.

  • Repeat— Enter how many pings should run in a specified time period.

  • Output Parameters—The following parameters are displayed in the test result:

    • Source—The AOS-S switch name.

    • Destination—The hostname or IP address of the destination.

      If you enter a destination that cannot be reached within 10 minutes, the test fails automatically.

    • Host—A single hop or a list of hops indicating the order the packets travel through these devices.

      Note:

      • The Results panel displays the hops only when probe response is received within 10 minutes.

      • Connector lines between hops and clicking on hops are not supported in this release.

    • Latency—The time delay experienced at each hop.

PoE Bounce Test

The Power over Ethernet (PoE) Bounce test temporarily disables PoE on a port for a specific duration and then restarts the PoE enabled port and the device that is either connected to the PoE port or powered by it. This can be useful to remotely reboot a connected PoE-powered device.

To perform PoE Bounce test on an AOS-S switch, complete the following steps:

  1. Under Test, select the PoE Bounce radio button.

    The Source field is automatically populated with the selected AOS-S switch name.

  2. In the Ports field, enter the port number.

  3. Optionally, schedule the tests periodically using the Repeat field.

  4. Click Start Test.

    The Results panel on the right displays the test output.

The following image displays the PoE Bounce test page for an AOS-S switch and displays the output in graphical format.

Port Bounce Test

The Port Bounce test briefly disables and re-enables a device interface. This can be useful to reset the network connection for a client connected on the device port.

To perform Port Bounce test on an AOS-S switch, complete the following steps:

  1. Under Test, select the Port Bounce radio button.

  2. In the Ports field, enter the port number.
