# NOS Platform Options

Extreme NOS Ansible modules only support CLI connections today. `httpapi` modules may be added in future. This page offers details on how to use `network_cli` on NOS in Ansible >= 2.7.

    - Example CLI Task

## Connections Available

| CLI
--- | ---
Protocol | SSH
Credentials | uses SSH keys / SSH-agent if present accepts `-u myuser -k` if using password
Indirect Access | via a bastion (jump host)
Connection Settings | `ansible_connection: network_cli`
Enable Mode (Privilege Escalation) | not supported by NOS
Returned Data Format | `stdout[0].`

NOS does not support `ansible_connection: local`. You must use `ansible_connection: network_cli`.

## Using CLI in Ansible >= 2.7

### Example CLI `group_vars/nos.yml`

    ansible_connection: network_cli
    ansible_network_os: nos
    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

    - name: Get version information (nos)
      nos_command:
        commands: "show version"
      register: show_ver
      when: ansible_network_os == 'nos'

Warning

Never store passwords in plain text. We recommend using SSH keys to authenticate SSH connections. Ansible supports ssh-agent to manage your SSH keys. If you must use passwords to authenticate SSH connections, we recommend encrypting them with Ansible Vault.
