Cisco built-in variables (available in EEM applets)
Defined by Cisco and can be read-only or read-write. The read-only variables are set by the system
before an applet starts to execute. The single read-write variable, _exit_status, allows you to set the
exit status for policies triggered from synchronous events.

exit status for policies triggered from synchronous events.
Cisco-defined environment variables and Cisco system-defined environment variables might apply to
one specific event detector or to all event detectors. Environment variables that are user-defined or
defined by Cisco in a sample policy are set by using the event manager environment global
configuration command. You must defined the variables in the EEM policy before you register the
policy.
