Using the Bridge Troubleshooter

HPE Aruba Networking Central offers the following test designed to help you diagnose and fix issues related to Bridge 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 ping test on a Bridge, 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 Bridges allows the following settings:

  • 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.

  • Source interface — Select from Ports or Cellular.

    • When choosing Ports, choose from etho or eth1 in the Ports dropdown.
