+* `tripleo_overcloud_netenv_validate_poll`: (Integer) Number of seconds to wait between each checks to see if the command has completed. Default: 10
+* `tripleo_overcloud_netenv_validate_timeout`: (Integer) Number in seconds to wait for the ansible execution of the command to finish. Default: 3600
+
+Output Variables
+----------------
+
+* `tripleo_overcloud_netenv_validate_output`: (String) The command standard output.
+* `tripleo_overcloud_netenv_validate_result`: Ansible shell execution results
+
+Dependencies
+------------
+
+None.
