How to enable support for third-party Modules on Arista Switches

Time: 2023-06-25
        Arista switch will authenticate the access module in the default state, and when the access module is verified to be non-Arista original, it may take actions such as shutting down the port or popping up an alarm prompt; at the same time, Arista also provides commands to support the use of third-party modules.
        Let's take Arista DCS-7160-48YC6-F switch as an example to learn how to turn on the support for third-party modules in Arista switches:
        1. When the third-party module is accessed to Arista switch, the module cannot be linked up, the port indicator shows an orange state, the port errdisabled and pop-up alarm message;
        2. In global configuration mode, execute the command "service unsupported-transceiver licensee name", the switch will allow the use of third-party modules;
        Note: This command is a hidden command and cannot be found by ? to find the command, and you cannot use the Tab key to complete the command. When executing this command, you need to remove the access module first, otherwise you need to re-plug the module or reboot to recognize the optical modules from other vendors.
        Description：licensee name is the licensee name and license value, you can refer to the following way to create (taken from arista official document EOS-User-Manual.pdf, only some models of switches support it) or submit the license request to marketing@arista.com.

        3. After allowing the use of the third-party module, the module can link up normally and recognize the information of the optical module normally;
        4. In system view mode, execute the command "no service unsupported-transceiver Licensee name" to exit the mode of using third-party modules;
