salt.modules.arista_pyeapi¶

Arista pyeapi¶

New in version 2019.2.0.

Execution module to interface the connection with Arista switches, connecting to the remote network device using the pyeapi library. It is flexible enough to execute the commands both when running under an Arista Proxy Minion, as well as running under a Regular Minion by specifying the connection arguments, i.e., device_type, host, username, password etc.

codeauthor: Mircea Ulinic <ping@mirceaulinic.net>
maturity: new
depends: pyeapi
platform: unix

Note

To understand how to correctly enable the eAPI on your switch, please check https://eos.arista.com/arista-eapi-101/.

Dependencies¶

The pyeapi Execution module requires the Python Client for eAPI (pyeapi) to be installed: pip install pyeapi.

Usage¶

This module can equally be used via the pyeapi Proxy module or directly from an arbitrary (Proxy) Minion that is running on a machine having access to the network device API, and the pyeapi library is installed.

When running outside of the pyeapi Proxy (i.e., from another Proxy Minion type, or regular Minion), the pyeapi connection arguments can be either specified from the CLI when executing the command, or in a configuration block under the pyeapi key in the configuration opts (i.e., (Proxy) Minion configuration file), or Pillar. The module supports these simultaneously. These fields are the exact same supported by the pyeapi Proxy Module:

transport: https: Specifies the type of connection transport to use. Valid values for the connection are socket, http_local, http, and https.
host: localhost: The IP address or DNS host name of the connection device.
username: admin: The username to pass to the device to authenticate the eAPI connection.
password: The password to pass to the device to authenticate the eAPI connection.
port: The TCP port of the endpoint for the eAPI connection. If this keyword is not specified, the default value is automatically determined by the transport type (80 for http, or 443 for https).
enablepwd: The enable mode password if required by the destination node.

Example (when not running in a pyeapi Proxy Minion):

pyeapi:
  username: test
  password: test

In case the username and password are the same on any device you are targeting, the block above (besides other parameters specific to your environment you might need) should suffice to be able to execute commands from outside a pyeapi Proxy, e.g.:

salt '*' pyeapi.run_commands 'show version' 'show interfaces'
salt '*' pyeapi.config 'ntp server 1.2.3.4'

Note

Remember that the above applies only when not running in a pyeapi Proxy Minion. If you want to use the pyeapi Proxy, please follow the documentation notes for a proper setup.

salt.modules.arista_pyeapi.config(commands=None, config_file=None, template_engine='jinja', context=None, defaults=None, saltenv='base', **kwargs)¶

Configures the node with the specified commands.

This method is used to send configuration commands to the node. It will take either a string or a list and prepend the necessary commands to put the session into config mode.

Returns the diff after the configuration commands are loaded.

config_file

The source file with the configuration commands to be sent to the device.

The file can also be a template that can be rendered using the template engine of choice.

This can be specified using the absolute path to the file, or using one of the following URL schemes:

salt://, to fetch the file from the Salt fileserver.
http:// or https://
ftp://
s3://
swift://

commands

The commands to send to the node in config mode. If the commands argument is a string it will be cast to a list. The list of commands will also be prepended with the necessary commands to put the session in config mode.

Note

This argument is ignored when config_file is specified.

template_engine: jinja

The template engine to use when rendering the source file. Default: jinja. To simply fetch the file without attempting to render, set this argument to None.

context

Variables to add to the template context.

defaults

Default values of the context dict.

transport: https

Specifies the type of connection transport to use. Valid values for the connection are socket, http_local, http, and https.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

host: localhost

The IP address or DNS host name of the connection device.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

username: admin

The username to pass to the device to authenticate the eAPI connection.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

password

The password to pass to the device to authenticate the eAPI connection.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

port

The TCP port of the endpoint for the eAPI connection. If this keyword is not specified, the default value is automatically determined by the transport type (80 for http, or 443 for https).

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

enablepwd

The enable mode password if required by the destination node.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

CLI Example:

salt '*' pyeapi.config commands="['ntp server 1.2.3.4', 'ntp server 5.6.7.8']"
salt '*' pyeapi.config config_file=salt://config.txt
salt '*' pyeapi.config config_file=https://bit.ly/2LGLcDy context="{'servers': ['1.2.3.4']}"

salt.modules.arista_pyeapi.get_config(config='running-config', params=None, as_string=False, **kwargs)¶

Retrieves the config from the device.

This method will retrieve the config from the node as either a string or a list object. The config to retrieve can be specified as either the startup-config or the running-config.

config: running-config: Specifies to return either the nodes startup-config or running-config. The default value is the running-config.
params: A string of keywords to append to the command for retrieving the config.
as_string: False: Flag that determines the response. If True, then the configuration is returned as a raw string. If False, then the configuration is returned as a list. The default value is False.
transport: https: Specifies the type of connection transport to use. Valid values for the connection are socket, http_local, http, and https.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.

salt.modules.arista_pyeapi.get_connection(**kwargs)¶

Return the connection object to the pyeapi Node.

Warning

This function returns an unserializable object, hence it is not meant to be used on the CLI. This should mainly be used when invoked from other modules for the low level connection with the network device.

kwargs: Key-value dictionary with the authentication details.

USAGE Example:

conn = __salt__['pyeapi.get_connection'](host='router1.example.com',
                                         username='example',
                                         password='example')
show_ver = conn.run_commands(['show version', 'show interfaces'])

salt.modules.arista_pyeapi.run_commands(*commands, **kwargs)¶

Sends the commands over the transport to the device.

This function sends the commands to the device using the nodes transport. This is a lower layer function that shouldn't normally need to be used, preferring instead to use config() or enable().

transport: https: Specifies the type of connection transport to use. Valid values for the connection are socket, http_local, http, and https.

Note

This argument does not need to be specified when running in a pyeapi Proxy Minion.
host: localhost: The IP address or DNS host name of the connection device.
