MAC Based

Geofencing is a security feature that defines a virtual boundary for a device’s operational area. When this boundary is breached, the device’s functionality halts.

Overview

Trusted MAC Address-based geofencing allows the edge controller to operate only when certain trusted MAC addresses are detected. This feature, under the Security section, currently activates only during the boot-up process.

Trigger Conditions

Trusted MAC Address-based geofencing activates at boot-up if:

1. Any mandatory trusted MAC address is missing.
2. The number of discovered trusted MAC addresses is below the configured threshold.

Functionality

After updating the trusted MAC configuration, “SAVE CHANGES” must be executed. The main functionalities include:

Enable/Disable Geofence

Geofencing can be enabled through the enable button. At least one trusted MAC address must be added to activate geofencing.

Add Trusted MAC Address

1. Manual Entry – Enter the MAC address, subnet, and (optional) mark it as mandatory. If a mandatory MAC address is not detected during reboot, geofencing activates, shutting down data flow.
   
2. Discover Local LAN MAC Addresses – Start MAC discovery across LAN networks. After discovery completes, select a MAC address from the dropdown to populate fields automatically.
   
   

Configure a threshold count for detected MAC addresses to prevent shutdown. This count cannot exceed the total number of trusted MAC addresses added.

Delete MAC Address

Remove any listed MAC address using the delete button and confirm changes by saving.

Only saved changes are applied to the edge controller. Unsaved changes display a warning icon.

Result

Once configured, the trusted MAC addresses display as below:

If conditions are unmet post-reboot:

• Alerts and ELK dashboard notifications are generated.
• CPE logs display detailed messages.

Known Limitations

• Only supports Trusted MAC Address-based geofencing.
• Activated only during system reboot.

Future Enhancements

• Additional geofencing features (e.g., WiFi-based, LTE-based).
