Ansible always writes config even nothing changed

fhk-cwempe
Level 1
Level 1

Hello,

I am starting to use Ansible for our switch/router configuration.
I created a playbook with some tasks and at the end I want to 'write mem' the config if there have been changes.

 

    - name: Save config to NVRAM
      cisco.ios.ios_config:
        save_when: modified

 

But this gets executed every time.
Even if I delete all other tasks and do a manual 'write mem' right before.

The documentation says:

 

If the argument is set to modified, then the running-config will only be copied to the startup-config if it has changed since the last save to startup-config.

 

https://docs.ansible.com/ansible/latest/collections/cisco/ios/ios_config_module.html

Why is this nor working?
Am I missing something?

My test device:

 

Model              SW Version
-----              ----------
C9200CX-12P-2X2G   17.09.01  

 

Ansible output:
