Ansible + Cisco idempotence

问题

So I'm doing some testing with Ansible to manage Cisco devices (specifically a 3750 in this case). I'm able to add my VLAN's and Loopbacks with no issue.

Just trying to get Ansible to stop registering a change in the task when the Loopback or VLAN exists.

Right now my play looks like this:

    - name: Set the IP for Loop 0
  ios_config:
    provider: "{{ connection }}"
    lines:
      - description AnsibleLoop0
      - ip address 8.8.8.8 255.255.255.0
    before:
      - interface Loopback0
    match: exact

Anytime this task is run, Ansible registers it like a change:

changed: [switch] => {"changed": true, "updates": ["interface Loopback0", "description AnsibleLoop0", "ip address 8.8.8.8 255.255.255.0"], "warnings": []}

I've tried different match types (line, exact) to no avail. Maybe I'm getting something wrong here.

I thought that if I had the play insert the lines exactly like how they would show up in a show run it wouldnt register it as a change?

Any help here would be appreciated!

You could be experiencing this issue:

Are you saving the configuration changes each time to the Cisco device using save: "yes” in your playbook? I had the same problem and I was saving the config each time the playbook ran. Setting that to no just to test, after the first run reports changed=True sequential runs would report back changed=False by Ansible.
