Notes

Note

  • We highly recommend using your own value as the policyid instead of 0, while ‘0’ is a special placeholder that allows the backend to assign the latest available number for the object, it does have limitations. Please find more details in Q&A.

  • Legacy fortiosapi has been deprecated, httpapi is the preferred way to run playbooks

  • The module supports check_mode.
