Those who wish to use junos-eznc (PyEZ) version >= 2.1.0, must
use the latest salt code from github until the next release.

Installs the given configuration file into the candidate configuration.

Path where the configuration/template file is present. If the file has
a ``.conf`` extension, the content is treated as text format. If the
file has a ``.xml`` extension, the content is treated as XML format. If
the file has a ``.set`` extension, the content is treated as Junos OS
``set`` commands.
mode : exclusive
The mode in which the configuration is locked. Can be one of
``private``, ``dynamic``, ``batch``, ``exclusive``.
dev_timeout : 30
Set NETCONF RPC timeout. Can be used for commands which take a while to
execute.
overwrite : False
Set to ``True`` if you want this file is to completely replace the
configuration file.
replace : False
Specify whether the configuration file uses ``replace:`` statements. If
``True``, only those statements under the ``replace`` tag will be
changed.
format
Determines the format of the contents
update : False
Compare a complete loaded configuration against the candidate
configuration. For each hierarchy level or configuration object that is
different in the two configurations, the version in the loaded
configuration replaces the version in the candidate configuration. When
the configuration is later committed, only system processes that are
affected by the changed configuration elements parse the new
configuration. This action is supported from PyEZ 2.1.

When ``True`` allows unified in-service software upgrade
(ISSU) feature enables you to upgrade between two different Junos OS
releases with no disruption on the control plane and with minimal
disruption of traffic.
bool nssu:
When ``True`` allows nonstop software upgrade (NSSU)
enables you to upgrade the software running on a Juniper Networks
EX Series Virtual Chassis or a Juniper Networks EX Series Ethernet
Switch with redundant Routing Engines with a single command and
minimal disruption to network traffic.

def load(path=None, **kwargs):
'''
Loads the configuration from the file provided onto the device.
path (required)
Path where the configuration/template file is present. If the file has
a ``.conf`` extension, the content is treated as text format. If the
file has a ``.xml`` extension, the content is treated as XML format. If
the file has a ``.set`` extension, the content is treated as Junos OS
``set`` commands.
overwrite : False
Set to ``True`` if you want this file is to completely replace the
configuration file.
replace : False
Specify whether the configuration file uses ``replace:`` statements. If
``True``, only those statements under the ``replace`` tag will be
changed.
format
Determines the format of the contents
update : False
Compare a complete loaded configuration against the candidate
configuration. For each hierarchy level or configuration object that is
different in the two configurations, the version in the loaded
configuration replaces the version in the candidate configuration. When
the configuration is later committed, only system processes that are
affected by the changed configuration elements parse the new
configuration. This action is supported from PyEZ 2.1.
template_vars
Variables to be passed into the template processing engine in addition to
those present in pillar, the minion configuration, grains, etc. You may
reference these variables in your template like so:
