Interfaces Data and Test Results

This topic provides information about the results of the tests that Paragon Automation executes to determine the state of the device interfaces.

Overview

The Interfaces accordion displays the interfaces data and results of the tests that Paragon Automation executes to determine that:

  • The device’s interfaces are up.

  • There are no port flapping issues.

  • The input and output traffic does not exceed the threshold limit.

You can also view events (alerts and alarms), if any, for the device on the Interfaces accordion.

To access the Interfaces accordion, navigate to the Observability > Health > Troubleshoot Devices page. Click a device name to access the Device-Name page. Click the Interfaces (accordion) in the Overview tab.

The top-right corner of the accordion displays the overall health of the interfaces. The various states are:

  • Healthy—The interfaces are healthy.

  • Being Monitored—The health of the interfaces is being monitored.

  • Action Needed—The interfaces have issues that you must address (might not be immediately).

  • Urgent Action Needed—The interfaces have issues that you must address immediately.

Table 1 lists the results of the interface checks.
