Aruba Central Next GenInstall

Overview

This node interacts with Aruba Central Next Gen API to retrieve detailed monitoring data about access points (APs). Specifically, the Get AP Port Collision Errors operation fetches collision error statistics for a specified port on an access point over a given time range. This is useful for network administrators who want to monitor and troubleshoot physical layer issues on AP ports that might affect network performance or reliability.

Common scenarios:

• Diagnosing network issues related to port collisions on APs.
• Monitoring port health and error trends over time.
• Integrating AP port error metrics into broader network monitoring dashboards or automation workflows.

Practical example:
A network engineer wants to track collision errors on port 0 of a specific AP identified by its serial number during the last 24 hours to identify if there are any hardware or cabling issues causing degraded performance.

Properties

Output

The node outputs JSON data containing the collision error metrics for the specified AP port within the requested time range. The structure typically includes timestamps and corresponding collision error counts or rates.

If binary data were output, it would represent raw or processed telemetry data, but in this case, the output is purely JSON structured monitoring data.

Dependencies

• Requires an active connection to Aruba Central Next Gen API via an API key credential configured in n8n.
• The node depends on proper OAuth2 authentication credentials set up in n8n to authorize API requests.
• Network connectivity to Aruba Central services is necessary.

Troubleshooting

• Common issues:

  • Invalid or missing serial number or port index parameters will cause the API call to fail.
  • Incorrect time range formats or invalid date values may result in no data returned or errors.
  • Network or authentication failures can prevent successful API calls.

• Error messages:

  • "Unknown error in node execution": Generic catch-all error; check node parameters and API credentials.
  • Authentication errors indicate misconfigured or expired API tokens.
  • Validation errors usually relate to missing required properties like serial number or port index.

• Resolutions:

  • Verify all required input properties are correctly set.
  • Ensure API credentials are valid and have sufficient permissions.
  • Use Debug Mode to enable detailed logs for deeper insight into failures.
