napalm – Provides persistent connection using NAPALM

New in version 2.8.

Synopsis

  • This connection plugin provides connectivity to network devices using the NAPALM network device abstraction library. This library requires certain features to be enabled on network devices depending on the destination device operating system. The connection plugin requires napalm to be installed locally on the Ansible controller.

Requirements

The below requirements are needed on the local master node that executes this connection.

Parameters

Parameter Choices/Defaults Configuration Comments
host
-
Default:
inventory_hostname
var: ansible_host
Specifies the remote device FQDN or IP address to establish the SSH connection to.
host_key_auto_add
boolean
Default:
no
ini entries:

[paramiko_connection]
host_key_auto_add = no

env:ANSIBLE_HOST_KEY_AUTO_ADD
By default, Ansible will prompt the user before adding SSH keys to the known hosts file. By enabling this option, unknown host keys will automatically be added to the known hosts file.
Be sure to fully understand the security implications of enabling this option on production systems as it could create a security vulnerability.
network_os
-
var: ansible_network_os
Configures the device platform network operating system. This value is used to load a napalm device abstraction.
password
-
var: ansible_password
var: ansible_ssh_pass
var: ansible_ssh_password
Configures the user password used to authenticate to the remote device when first establishing the SSH connection.
persistent_command_timeout
integer
Default:
30
ini entries:

[persistent_connection]
command_timeout = 30

env:ANSIBLE_PERSISTENT_COMMAND_TIMEOUT
var: ansible_command_timeout
Configures, in seconds, the amount of time to wait for a command to return from the remote device. If this timer is exceeded before the command returns, the connection plugin will raise an exception and close.
persistent_connect_timeout
integer
Default:
30
ini entries:

[persistent_connection]
connect_timeout = 30

env:ANSIBLE_PERSISTENT_CONNECT_TIMEOUT
var: ansible_connect_timeout
Configures, in seconds, the amount of time to wait when trying to initially establish a persistent connection. If this value expires before the connection to the remote device is completed, the connection will fail.
port
integer
Default:
22
ini entries:

[defaults]
remote_port = 22

env:ANSIBLE_REMOTE_PORT
var: ansible_port
Specifies the port on the remote device that listens for connections when establishing the SSH connection.
private_key_file
-
ini entries:

[defaults]
private_key_file = VALUE

env:ANSIBLE_PRIVATE_KEY_FILE
var: ansible_private_key_file
The private SSH key or certificate file used to authenticate to the remote device when first establishing the SSH connection.
remote_user
-
ini entries:

[defaults]
remote_user = VALUE

env:ANSIBLE_REMOTE_USER
var: ansible_user
The username used to authenticate to the remote device when the SSH connection is first established. If the remote_user is not specified, the connection will use the username of the logged in user.
Can be configured from the CLI via the --user or -u options.
timeout
integer
Default:
120
Sets the connection time, in seconds, for communicating with the remote device. This timeout is used as the default timeout value for commands when issuing a command to the network CLI. If the command does not return in timeout seconds, an error is generated.
