Creating new device plugins

  1. Subclass the abstract class networking_generic_switch.devices.GenericSwitch and implement all the abstract methods it defines.

    • Your class must accept as first argument a dictionary that contains all fields given in the device config section of the ML2 plugin config. This will be available as self.config in the instantiated object. The second argument is the device name as specified in the configuration. It is recommended to accept and pass *args and **kwargs to the __init__ method of the parent class: this helps to stay compatible with future changes of the base class.

  2. Register your class under generic_switch.devices entrypoint.

  3. Add your device config to the plugin configuration file (/etc/neutron/plugins/ml2/ml2_conf_genericswitch.ini by default). The only required option is device_type that must be equal to the entrypoint you have registered your plugin under, as it is used for plugin lookup (see provided Netmiko-based plugins for example).
