If you experience intermittent packet loss toward nodes:
- Perform a ping toward ISP gateway:
- Ping the IP address of the ISP gateway to check for packet loss and response times.
- Analyze the results to determine if there is any intermittent packet loss.
- Contact the ISP to inquire about any connectivity issues in your area.
- Perform a ping toward the server default gateway (/64 IPv6 subnet):
- Ping the IP address of the server's default gateway within the IPv6 subnet.
- Monitor the packet loss and response times to identify any irregularities.
- Check if another server with the same IPv6 subnet has the same issue:
- Test the network connectivity and ping the same IPv6 subnet from another server.
- Compare the results to determine if the intermittent packet loss is specific to a particular server or affects multiple nodes.
- Verify the cabling and port status on the switch:
- Inspect the physical connections between the affected nodes and the switch.
- Ensure that the network cables are securely plugged into the correct ports on both ends.
- Check for any signs of damage or loose connections in the cables.
- Test the connectivity by using different network cables or ports.
- Check for recent port flaps/link failures inside the switch logs:
- Access the switch logs or monitoring systems to identify any recent port flapping or link failures.
- Investigate the logs for any abnormalities or patterns related to the intermittent packet loss.
- Analyze any recorded events or error messages that might provide insights into the issue.
