Expected Behavior

the switch should be remove without decommission. Becuase I get no information that I must decommission this switch before I remove it.

Actual Behavior

I have create aci-rest module for this, so the switch will be remove from the apic controller

Playbook tasks to Reproduce

• name: TASK 24 - Delete fabric nodes spine or leaf
  cisco.aci.aci_fabric_node:
  <<: *aci_login
  serial: "{{ item.serial }}"
  pod_id: "{{ item.podid }}"
  node_id: "{{ item.nodeid }}"
  switch: "{{ item.prefix }}{{ item.nodeid }}"
  role: "{{ item.role }}"
  state: "absent"
  loop: "{{ aci_fabric_node }}"
  when:
• item.state == "absent"
  tags: [ never, delete ]

How can we fix this problem. I want used the module for decommission a fabric switch.

Best regards

Same issue in 4.2 and 5.2 versions

@mic-ansible Thank you for opening the issue. We'll have a discussion and get back to you here.
For now I have added it to our to-do list.

[anvitha-jain]

@mic-ansible this is because of the change in API after 4.2 version, this issue has been put on our to-do and will be resolved soon.
