Overview
This node interacts with Aruba Central Next Gen API to retrieve monitoring data related to Access Points (APs). Specifically, the "Get AP Port CRC Errors" operation fetches cyclic redundancy check (CRC) error statistics for a specified port on an access point. This is useful for network administrators who want to monitor the health and integrity of data transmission on AP ports, helping identify physical layer issues or cabling problems.
Practical scenarios include:
- Diagnosing network performance degradation by checking CRC errors on AP ports.
- Monitoring port error trends over time to proactively maintain network hardware.
- Integrating AP port error metrics into broader network monitoring workflows.
Properties
| Name | Meaning |
|---|---|
| Debug Mode | Whether to enable detailed debug logs for troubleshooting. |
| Domain | API domain to interact with. Options: "Monitoring" (monitor devices, clients, sites), "Configuration" (configure devices, groups, profiles). For this operation, "Monitoring" is used. |
| Serial Number | Access point serial number identifying the specific AP to query. |
| Port Index | Port index of the access point to retrieve CRC error data for. |
| Time Range | Optional start and end times (ISO 8601 format) to specify the period for data retrieval. |
Output
The node outputs JSON data containing the CRC error statistics for the specified AP port within the given time range. The structure typically includes timestamps and corresponding CRC error counts or rates, enabling trend analysis.
If binary data were output, it would represent raw or encoded data related to the AP port metrics, but this operation focuses on JSON-formatted monitoring data.
Dependencies
- Requires an active connection to Aruba Central Next Gen API with appropriate API authentication credentials configured in n8n.
- The node depends on the "arubaCentralNextGenOAuth2Api" credential (an OAuth2 API key or token) to authenticate requests.
- Network connectivity to Aruba Central services is necessary.
Troubleshooting
Common Issues:
- Invalid or missing serial number or port index may cause the API to return errors or empty results.
- Incorrect time range formatting can lead to request failures.
- Insufficient permissions or expired API tokens will result in authentication errors.
Error Messages:
- "Unknown error in node execution": Generic catch-all error; check debug logs if enabled.
- Authentication errors: Verify API credentials and refresh tokens as needed.
- Validation errors: Ensure required properties like serial number and port index are correctly set.
Enabling "Debug Mode" helps capture detailed logs to diagnose issues.
