Using Ansible ios_facts module
Here is a simple playbook to gather ios facts.
I took the output and pasted it into one of the may JSON lint/editors on
line to easily see the structure and then added a debug statement for the
key:value pair I wanted. Version in this case.

- hosts: cisco
connection: local
gather_facts: False
ignore_errors: yes
vars:
cli:
host: "{{ host }}"
username: "{{ username }}"
password: "{{ password }}"
tasks:
- name: Gather NX-OS Facts
ios_facts:
provider: "{{ cli }}"
register: facts_output
- debug: var=facts_output
- debug: var=facts_output.ansible_facts.ansible_net_version
- local_action: copy content="{{ facts_output }}" dest="./{{
inventory_hostname }}.txt"
TASK [debug]
********************************************************************************************************************************************************
ok: [arctic-3650] => {
"facts_output.ansible_facts.ansible_net_version": "03.06.06E"
