Using the Gateway Troubleshooter

HPE Aruba Networking Central offers the following tests designed to help you diagnose and fix issues related to Gateway 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 a Gateway, complete the following steps:

  1. Under Test, select the Ping radio button.

    The Source field is automatically populated with the selected Gateway name.

  2. In the Destination field, enter the hostname or IP address.
    Enable Use IPV6 toggle for IPV6 addresses.

  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 Gateways allows the following settings:

  • Packet Size— in bytes (10-2000)
