Cisco NXOS supports multiple connections. This page offers details on how each connection works in Ansible 2.5 and how to use it.

Using CLI in Ansible 2.5
|
||
|
================================================================================
|
||
|
|
||
|
Example CLI ``group_vars/nxos.yml``
|
||
|
-----------------------------------
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
ansible_connection: network_cli
|
||
|
ansible_network_os: nxos
|
||
|
ansible_user: myuser
|
||
|
ansible_ssh_pass: !vault...
|
||
|
ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q bastion01"'
|
||
|
|
||
|
|
||
|
- If you are using SSH keys (including an ssh-agent) you can remove the ``ansible_ssh_pass`` configuration.
|
||
|
- If you are accessing your host directly (not through a bastion/jump host) you can remove the ``ansible_ssh_common_args`` configuration.
|
||
|
- If you are accessing your host through a bastion/jump host, you cannot include your SSH password in the ``ProxyCommand`` directive. To prevent secrets from leaking out (for example in ``ps`` output), SSH does not support providing passwords via environment variables.
|
||
|
|
||
|
Example CLI Task
|
||
|
----------------
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
- name: Backup current switch config (nxos)
|
||
|
nxos_config:
|
||
|
backup: yes
|
||
|
register: backup_nxos_location
|
||
|
when: ansible_network_os == 'nxos'
|

Using NX-API in Ansible 2.5
|
||
|
================================================================================
|
||
|
|
||
|
Enabling NX-API
|
||
|
---------------
|
||
|
|
||
|
Before you can use NX-API to connect to a switch, you must enable NX-API. To enable NX-API on a new switch via Ansible, use the ``nxos_nxapi`` module via the CLI connection. Set up group_vars/nxos.yml just like in the CLI example above, then run a playbook task like this:
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
- name: Enable NX-API
|
||
|
nxos_nxapi:
|
||
|
enable_http: yes
|
||
|
enable_https: yes
|
||
|
when: ansible_network_os == 'nxos'
|
||
|
|
||
|
To find out more about the options for enabling HTTP/HTTPS and local http see the :ref:`nxos_nxapi <nxos_nxapi>` module documentation.
|
||
|
|
||
|
Once NX-API is enabled, change your ``group_vars/nxos.yml`` to use the NX-API connection.
|
||
|
|
||
|
Example NX-API ``group_vars/nxos.yml``
|
||
|
--------------------------------------
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
ansible_connection: local
|
||
|
ansible_network_os: nxos
|
||
|
ansible_user: myuser
|
||
|
ansible_ssh_pass: !vault...
|
||
|
nxapi:
|
||
|
host: "{{ inventory_hostname }}"
|
||
|
transport: nxapi
|
||
|
proxy_env:
|
||
|
http_proxy: http://proxy.example.com:8080
|
||
|
|
||
|
- If you are accessing your host directly (not through a web proxy) you can remove the ``proxy_env`` configuration.
|
||
|
- If you are accessing your host through a web proxy using ``https``, change ``http_proxy`` to ``https_proxy``.
|
||
|
|
||
|
|
||
|
Example NX-API Task
|
||
|
-------------------
|
||
|
|
||
|
.. code-block:: yaml
|
||
|
|
||
|
- name: Backup current switch config (nxos)
|
||
|
nxos_config:
|
||
|
backup: yes
|
||
|
provider: "{{ nxapi }}"
|
||
|
register: backup_nxos_location
|
||
|
environment: "{{ proxy_env }}"
|
||
|
when: ansible_network_os == 'nxos'
|
||
|
|
||
|
In this example two variables defined in ``group_vars`` get passed to the module of the task:
|
||
|
|
||
|
- the ``nxapi`` variable gets passed to the ``provider`` option of the module
|
||
|
- the ``proxy_env`` variable gets passed to the ``environment`` option of the module
