Notes

Note

  • Module assumes a complete list of firewall rules are passed as a parameter.

  • If there is interest in this module allowing manipulation of a single firewall rule, please submit an issue against this module.

  • More information about the Meraki API can be found at https://dashboard.meraki.com/api_docs.

  • Some of the options are likely only used for developers within Meraki.

  • As of Ansible 2.9, Meraki modules output keys as snake case. To use camel case, set the ANSIBLE_MERAKI_FORMAT environment variable to camelcase.

  • Ansible’s Meraki modules will stop supporting camel case output in Ansible 2.13. Please update your playbooks.

  • Check Mode downloads the current configuration from the dashboard, then compares changes against this download. Check Mode will report changed if there are differences in the configurations, but does not submit changes to the API for validation of change.
