17. From the command line, enter configuration mode and enter the show licenses command.

18. Write down the MAC addresses of primary, AUX, lan0_0, wan0_0, lan0_1, and wan0_1.

Note: After you enter the command, do not press Ctrl+C before the command completes. You will destroy the BIOS. Restart the appliance when prompted using the reload command.

The commands take a while to complete as they copy the BIOS and reconfigure the MAC addresses.

20. When prompted, reboot the appliance using the reload command.

21. Once the appliance reboots, enter the show licenses command and ensure that the licenses are valid.

22. Verify the MAC addresses of the primary and AUX interfaces.

The primary and AUX interfaces should have new MAC addresses. The MAC addresses of lan0_0, wan0_0, lan0_1, and wan0_1 remain the same.
