I seem to be having some issues making this playbook work. I want to just do a show run on all my cisco devices, but it keeps throwing errors about the ‘- vars:’ or something else. I am on the latest version. rpm -qa|grep -i ansible ansible-inventory-grapher-2.3.2-1.el7.noarch ansible-2.3.1.0-1.el7.noarch ansible-review-0.13.0-2.el7.noarch ansible-openstack-modules-0-20140902git79d751a.el7.noarch ansible-lint-3.4.12-1.el7.noarch ansible-doc-2.3.1.0-1.el7.noarch - vars: hosts: cisco-fw cli: hosts: “{{ cisco-fw }}” username: user password: password authorize: yes auth\_pass: password transport: cli tasks: - asa\_command: commands: - show version provider: “{{ cli }}” - asa\_command: commands: - show run - show memory provider: “{{ cli }}” - asa\_command: commands: - show version provider: “{{ cli }}” context: system Here is my output: sudo ansible-playbook asa-showrun.yml --check ERROR! Syntax Error while loading YAML. The error appears to have been in ‘/home/andrew.meyer/playbooks/asa-showrun.yml’: line 3, column 8, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: hosts: cisco-fw cli: ^ here ---

You have them in the wrong order, it should be this way - hosts: cisco-fw    vars:      cli: ---

So I figured that out. But now i’m not able to connect to any of the network devices. All of them are showing unreachable when running ansible-playbook with --check. Here is my config: cat asa-showrun.yml ---

Ok now i’m getting this - {“failed”: true, “msg”: “the field ‘args’ has an invalid value, which appears to include a variable that is undefined. The error was: ‘password’ is undefined\n\nThe error appears to have been in ‘/home/andrew.meyer/playbooks/asa-showrun.yml’: line 7, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tasks:\n - name:\n ^ here\n”} ---

It says password is undefined. Since you are using the variable password you need to set in some how in you play, extra\_vars, inventory or some other place you cat set variables in Ansible.
