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.

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

Example CLI group_vars/nos.yml

ansible_connection: network_cli
ansible_network_os: nos
ansible_user: myuser
ansible_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 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.
