This write-only INTEGER lets an administrator issue a control action on a specific port's administrative configuration, with defined values activate(1), deactivate(2), and reinitialize(3), and the change takes effect on the port immediately. An operator would use activate to bring a previously unconfigured port into service, deactivate to take a running port out of service without configuration, or reinitialize to apply a fresh configuration to a port that is currently running with an existing one. For example, writing the value 3 (reinitialize) to this object for a given port would immediately swap that port over to whatever new administrative configuration has been prepared for it.
