I am using junos\_check and like to run my playbook with the --check --diff arguments as it returns what configuration changes will actually be applied to the network device.

i.e.

[edit system arp]

- aging-timer 240;

- aging-timer 40;

However when using Ansible Tower with the Job Type: “Check” the argument --diff is not included.

I want to include --diff with Tower as I need to stage my changes before applying to production.

Any help appreciated,

Thank you,

Lance
