Aruba Central Next GenInstall

Overview

This node interacts with the Aruba Central Next Gen API to retrieve information about wired interfaces on a specific Gateway device. It is useful for network administrators who want to monitor or audit the physical network interfaces of their gateways, such as checking interface status, configurations, or troubleshooting connectivity issues.

A practical example would be automating the retrieval of all wired interfaces on a gateway identified by its serial number to integrate this data into a network monitoring dashboard or to trigger alerts if certain interfaces are down.

Properties

Output

The node outputs JSON data representing the list of wired interfaces for the specified gateway. Each item in the output array corresponds to one wired interface and typically includes details such as interface name, status, speed, MAC address, and other relevant interface metrics or configuration parameters.

If the node supports binary data output (not evident from the provided code), it would represent any associated files or raw data related to the interfaces, but based on the static analysis, the output is primarily structured JSON.

Dependencies

• Requires an active connection to Aruba Central Next Gen API.
• Needs an API authentication token configured via n8n credentials (an OAuth2 API key credential).
• The node depends on internal helper modules for executing operations and logging, which handle the actual API calls and debugging output.

Troubleshooting

• Common Issues:

  • Invalid or missing serial number will cause the API call to fail or return no data.
  • Incorrect domain selection may lead to unsupported operations or empty results.
  • Network connectivity issues or expired API tokens can cause authentication failures.

• Error Messages:

  • Errors thrown during execution will include messages like "Unknown error in node execution" or more specific API error messages if available.
  • Enabling Debug Mode helps reveal detailed logs that can assist in diagnosing problems.

• Resolutions:

  • Verify the serial number is correct and corresponds to an existing gateway.
  • Ensure the API credentials are valid and have sufficient permissions.
  • Use Debug Mode to get detailed logs and identify where the failure occurs.
