.. _nxos_platform_options: *************************************** NXOS Platform Options *************************************** The `Cisco NXOS `_ supports multiple connections. This page offers details on how each connection works in Ansible and how to use it. .. contents:: :local: Connections available ================================================================================ .. table:: :class: documentation-table ==================== ========================================== ========================= .. CLI NX-API ==================== ========================================== ========================= Protocol SSH HTTP(S) Credentials uses SSH keys / SSH-agent if present uses HTTPS certificates if present accepts ``-u myuser -k`` if using password Indirect Access by a bastion (jump host) by a web proxy Connection Settings ``ansible_connection:`` ``ansible_connection:`` ``ansible.netcommon.network_cli`` ``ansible.netcommon.httpapi`` |enable_mode| supported: use ``ansible_become: yes`` not supported by NX-API with ``ansible_become_method: enable`` and ``ansible_become_password:`` Returned Data Format ``stdout[0].`` ``stdout[0].messages[0].`` ==================== ========================================== ========================= .. |enable_mode| replace:: Enable Mode |br| (Privilege Escalation) |br| supported as of 2.5.3 The ``ansible_connection: local`` has been deprecated. Please use ``ansible_connection: ansible.netcommon.network_cli`` or ``ansible_connection: ansible.netcommon.httpapi`` instead. Using CLI in Ansible ==================== Example CLI ``group_vars/nxos.yml`` ----------------------------------- .. code-block:: yaml ansible_connection: ansible.netcommon.network_cli ansible_network_os: cisco.nxos.nxos ansible_user: myuser ansible_password: !vault... ansible_become: yes ansible_become_method: enable ansible_become_password: !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_password`` 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 through environment variables. Example CLI task ---------------- .. code-block:: yaml - name: Backup current switch config (nxos) cisco.nxos.nxos_config: backup: yes register: backup_nxos_location when: ansible_network_os == 'cisco.nxos.nxos' Using NX-API in Ansible ======================= 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 through Ansible, use the ``nxos_nxapi`` module through 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 cisco.nxos.nxos_nxapi: enable_http: yes enable_https: yes when: ansible_network_os == 'cisco.nxos.nxos' To find out more about the options for enabling HTTP/HTTPS and local http see the :ref:`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: ansible.netcommon.httpapi ansible_network_os: cisco.nxos.nxos ansible_user: myuser ansible_password: !vault... 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) cisco.nxos.nxos_config: backup: yes register: backup_nxos_location environment: "{{ proxy_env }}" when: ansible_network_os == 'cisco.nxos.nxos' In this example the ``proxy_env`` variable defined in ``group_vars`` gets passed to the ``environment`` option of the module used in the task. .. include:: shared_snippets/SSH_warning.txt Cisco Nexus platform support matrix =================================== The following platforms and software versions have been certified by Cisco to work with this version of Ansible. .. table:: Platform / Software Minimum Requirements :align: center =================== ===================== Supported Platforms Minimum NX-OS Version =================== ===================== Cisco Nexus N3k 7.0(3)I2(5) and later Cisco Nexus N9k 7.0(3)I2(5) and later Cisco Nexus N5k 7.3(0)N1(1) and later Cisco Nexus N6k 7.3(0)N1(1) and later Cisco Nexus N7k 7.3(0)D1(1) and later Cisco Nexus MDS 8.4(1) and later (Please see individual module documentation for compatibility) =================== ===================== .. table:: Platform Models :align: center ======== ============================================== Platform Description ======== ============================================== N3k Support includes N30xx, N31xx and N35xx models N5k Support includes all N5xxx models N6k Support includes all N6xxx models N7k Support includes all N7xxx models N9k Support includes all N9xxx models MDS Support includes all MDS 9xxx models ======== ============================================== .. seealso:: :ref:`timeout_options`
