EEM consists of three major components:
* Event statements - Events to monitor from another Cisco NX-OS component that may require
some action, workaround, or notification.
* Action statements - Actions that EEM can take, such as sending an e-mail, or disabling an
interface, to recover from an event.
* Policies - A combination of an event statement and an action statement. When the specified
event occurs, the configured action is executed.
