To view the license of a MikroTik device using RouterOS, you can follow several methods depending on whether you prefer to use the graphical user interface (WinBox) or the command line.

Below, we explain the steps for both methods:

Using WinBox (Graphical User Interface)

1. Connect to your MikroTik Device:
   • Open WinBox and connect to your MikroTik device using the IP address, username and password.
2. View License Information:
   • Once connected, go to "System" in the main menu.
   • Then click "License". This will show you a window with all the information related to the license of your MikroTik device, including the license level, the software serial number, and the license key if applicable.

Using the Terminal (Command Line)

1. Terminal Access:
   • You can access the terminal directly through WinBox or using any SSH client to connect to the device.
2. Command to View the License:
   • In the terminal, type the following command and press Enter:
     
     /system license print
     
   • This command will display details similar to those available in WinBox, including the license level, serial number, and other relevant details.

Typical Information Displayed

• License Level: MikroTik RouterOS comes with different license levels, from level 0 (demo) to level 6. Each level provides a different set of features and capabilities.
• Serial number: It is a unique identifier for your device license.
• Due date: Some licenses may have an expiration date, especially if it is a trial license.
• License Status: Information about whether the license is valid, has been revoked, or is pending update.

Additional considerations

• License Update: If you need to upgrade your RouterOS license to a higher level, you generally need to purchase an upgrade key from an official MikroTik reseller and apply it through the license section in WinBox or the terminal.
• Support: The license may also affect the type of technical support available for your device.

Checking and understanding your MikroTik equipment license is crucial to ensure you are operating within legal terms and have access to the features and support necessary for your networking needs.
