Using the AOS-CX Switch Troubleshooter

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

Note:

  • You can currently perform troubleshooting test for standalone and stack switches only.

  • All the listed tests can be scheduled to run periodically using the Repeat option.

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 ping test on an AOS-CX switch, complete the following steps:

  1. Under Test, select the Ping radio button.

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

  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-CX switches allow the following settings:

  • Use Management Interface—toggle switch to use VRF management interface. This is disabled by default.

    Note:

    The Use Management Interface parameter is available only for AOS-CX switches.

  • VRF Name— enter the VRF details.

  • Packet Size— in bytes (10-2000)

    • Identifies issues like fragmentation, latency, and packet loss that may not surface with default settings.

  • Packet Count— number of probes to send (1-100)

    • Ensures precise control over the test's duration and consistency, enabling repeatable and measurable diagnostics. It helps in identifying intermittent issues and analyzing performance trends.

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