Experiencing down links on your Nebula switch ports when they're connected to access points can be challenging. To address this, follow these troubleshooting steps to ensure a smooth and reliable connection:

1. Check Physical Connections: Start by checking that all cables are securely connected to the switch ports and the access points. A loose connection could be the root cause of the issue.

2. Inspect Cables for Damage: Look for any signs of wear or damage on the cables. Damaged cables can lead to poor or no connectivity. Replacing them might solve the problem.

3. Verify Power Supply: Confirm that all access points are adequately powered. A lack of power can make the devices appear disconnected or down from the switch's point of view.

4. Examine Switch Port Configuration: Access the Nebula switch's management interface to review the configurations of the affected ports. Make sure these ports are enabled and set up correctly to support the connected devices.

5. Test with a Different Port: If feasible, try connecting the access points to other ports on the switch to see if the problem persists. This can help determine if the issue is port-specific or more widespread.
