ios_facts doesn't return output when used in playbook but shows output in ad-hoc command. Why?

[Vikram S]

Below is my playbook to gather ios_facts info in GNS3 router. The output shows "VARIABLE IS NOT DEFINED!"

But when i gather ios_facts using ad-hoc command, it works. Why the difference?

----------------------------------------------------------------------------------------

name: PLAYBOOK 1 hosts: R1 gather_facts: true connection: network_cli

• vars: ansible_network_os: ios

  tasks:

  • name: IOS facts ios_facts: gather_subset: all

    register: print_output

  • debug: var=print_output.stdout_lines

OUTPUT: PLAY [PLAYBOOK 1] ***************************************************************************************************************************************************************************************************************************

TASK [Gathering Facts] ********************************************************************************************************************************************************************************************************************** ok: [R1]

TASK [IOS facts] **************************************************************************************************************************************************************************************************************************** ok: [R1]

TASK [debug] ******************************************************************************************************************************************************************************************************************************** ok: [R1] => { "print_output.stdout_lines": "VARIABLE IS NOT DEFINED!" }

PLAY RECAP ********************************************************************************************************************************************************************************************************************************** R1 : ok=3 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

--------------------------------------------------------------------------------------------------------------------------------

AD-HOC command:

ansible all -i "192.168.122.72", -c network_cli -u david-user -k -m ios_facts -e ansible_network_os=ios

SSH password:

The facts are gathered and prefixed with 'ansible_net_' (like
ansible_net_all_ipv4_addresses).
You should not use register.
