Optional arguments

NAPALM supports passing certain optional arguments to some drivers. To do that you have to pass a dictionary via the :code:optional_args parameter when creating the object::

>>> from napalm import get_network_driver
>>> driver = get_network_driver('vyos')
>>> optional_args = {'my_optional_arg1': 'my_value1', 'my_optional_arg2': 'my_value2'}
>>> device = driver('192.168.76.10', 'vagrant', 'this_is_not_a_secure_password', optional_args=optional_args)
>>> device.open()

List of supported optional arguments

---

• :code:port (vyos) - Allows you to specify a port other than the default.
• :code:key_file (vyos) - Netmiko/Paramiko argument, path to a private key file (default: 'False').

Prerequisites

VyOS has no native HTTP API or NETCONF capability. We are using Netmiko for ssh connections and scp file transfers. Having Netmiko installed in your working box is a prerequisite.

Configuration file

Currently VyOS driver supports two different configuration formats:

• load_replace_candidate - Full config file (with brackets) like in /config/config.boot Due to the OS nature, we do not support a replace using a set-style configuration format.
• load_merge_candidate - Currently driver supports set-style configuration format. Example

set system login banner pre-login "test"

Vyos require configuration file (load_replace) to contain comment like following

/* Warning: Do not remove the following line. */ /* === vyatta-config-version: "cluster@1:config-management@1:conntrack-sync@1:conntrack@1:cron@1:dhcp-relay@1:dhcp-server@4:firewall@5:ipsec@4:nat@4:qos@1:quagga@2:system@6:vrrp@1:wanloadbalance@3:webgui@1:webproxy@1:zone-policy@1" === */ /* Release version: VyOS 1.1.7 */

Otherwise VyOS reject load operation

Notes

• The NAPALM-vyos driver supports all Netmiko arguments as either standard arguments (hostname, username, password, timeout) or as optional_args (everything else).

• The NAPALM-vyos driver supports authentication with ssh key. Please specify path to a key in optional_args 'optional_args': {'key_file': '/home/user/ssh_private_key'}
