Does Knox Manage add additional licenses to the amount of licenses purchased as buffer slots?

Only Knox Suite Essentials Plan licenses (with a KLM12- prefix) and Knox Suite Enterprise Plan licenses (with a KLM11- or KLM12- prefix) include a 10% buffer. For example, if you purchase 100 Knox Suite Essentials Plan licenses, a maximum of 110 licenses can be used to register devices in Knox Manage.
