eos_config - Manage Arista EOS configuration sections

New in version 2.1.

Synopsis

  • Arista EOS configurations use a simple block indent file syntax for segmenting configuration into sections. This module provides an implementation for working with EOS configuration sections in a deterministic way. This module works with either CLI or eAPI transports.

Options

parameter required default choices comments
after
 no
The ordered set of commands to append to the end of the command stack if a change needs to be made. Just like with before this allows the playbook designer to append a set of commands to be executed after the command set.
auth_pass
 no none
Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTH_PASS will be used instead.
authorize
 no
  • yes
  • no
Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTHORIZE will be used instead.
backup
(added in 2.2)
 no
  • yes
  • no
This argument will cause the module to create a full backup of the current running-config from the remote device before any changes are made. The backup file is written to the backup folder in the playbook root directory. If the directory does not exist, it is created.
before
 no
The ordered set of commands to push on to the command stack if a change needs to be made. This allows the playbook designer the opportunity to perform configuration commands prior to pushing any changes without affecting how the set of commands are matched against the system.
defaults
(added in 2.2)
 no
  • yes
  • no
The defaults argument will influence how the running-config is collected from the device. When the value is set to true, the command used to collect the running-config is append with the all keyword. When the value is set to false, the command is issued without the all keyword
diff_against
(added in 2.4)
 no session
  • startup
  • running
  • intended
  • session
When using the ansible-playbook --diff command line argument the i module can generate diffs against different sources.
When this option is configure as startup, the module will return the diff of the running-config against the startup-config.
When this option is configured as intended, the module will return the diff of the running-config against the configuration provided in the intended_config argument.
When this option is configured as running, the module will return the before and after diff of the running-config with respect to any changes made to the device configuration.
When this option is configured as session, the diff returned will be based on the configuration session.
diff_ignore_lines
(added in 2.4)
 no
Use this argument to specify one or more lines that should be ignored during the diff. This is used for lines in the configuration that are automatically updated by the system. This argument takes a list of regular expressions or exact line matches.
force
 no
  • yes
  • no
The force argument instructs the module to not consider the current devices running-config. When set to true, this will cause the module to push the contents of src into the device without first checking if already configured.
Note this argument should be considered deprecated. To achieve the equivalent, set the match=none which is idempotent. This argument will be removed in a future release.
intended_config
(added in 2.4)
 no
The intended_config provides the master configuration that the node should conform to and is used to check the final running-config against. This argument will not modify any settings on the remote device and is strictly used to check the compliance of the current device's configuration against. When specifying this argument, the task should also modify the diff_against value and set it to intended.
lines
 no
The ordered set of commands that should be configured in the section. The commands must be the exact same commands as found in the device running-config. Be sure to note the configuration command syntax as some commands are automatically modified by the device config parser.
match
 no line
  • line
  • strict
  • exact
  • none
Instructs the module on the way to perform the matching of the set of commands against the current device config. If match is set to line, commands are matched line by line. If match is set to strict, command lines are matched with respect to position. If match is set to exact, command lines must be an equal match. Finally, if match is set to none, the module will not attempt to compare the source configuration with the running configuration on the remote device.
parents
 no
The ordered set of parents that uniquely identify the section the commands should be checked against. If the parents argument is omitted, the commands are checked against the set of top level or global commands.
provider
 no
A dict object containing connection details.
Dictionary object provider
parameter required default choices comments
username
 no
Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate either the CLI login or the eAPI authentication depending on which transport is used. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.
authorize
 no
  • yes
  • no
Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTHORIZE will be used instead.
ssh_keyfile
 no
Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
auth_pass
 no none
Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTH_PASS will be used instead.
host
 yes
Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
timeout
 no 10
Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
use_ssl
 no True
  • yes
  • no
Configures the transport to use SSL if set to true only when the transport=eapi. If the transport argument is not eapi, this value is ignored.
password
 no
Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or eapi transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
validate_certs
 no
  • yes
  • no
If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. If the transport argument is not eapi, this value is ignored.
port
 no 0 (use common port)
Specifies the port to use when building the connection to the remote device. This value applies to either cli or eapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
transport
 yes cli
  • eapi
  • cli
Configures the transport connection to use when connecting to the remote device.
replace
 no line
  • line
  • block
  • config
Instructs the module on the way to perform the configuration on the device. If the replace argument is set to line then the modified lines are pushed to the device in configuration mode. If the replace argument is set to block then the entire command block is pushed to the device in configuration mode if any line is not correct.
running_config
(added in 2.4)
 no
The module, by default, will connect to the remote device and retrieve the current running-config to use as a base for comparing against the contents of source. There are times when it is not desirable to have the task get the current running-config for every task in a playbook. The running_config argument allows the implementer to pass in the configuration to use as the base config for this module.
aliases: config
save
(added in 2.2)
 no
  • yes
  • no
The save argument instructs the module to save the running-config to startup-config. This operation is performed after any changes are made to the current running config. If no changes are made, the configuration is still saved to the startup config. This option will always cause the module to return changed.
This option is deprecated as of Ansible 2.4, use save_when
save_when
(added in 2.4)
 no never
  • always
  • never
  • modified
When changes are made to the device running-configuration, the changes are not copied to non-volatile storage by default. Using this argument will change that before. If the argument is set to always, then the running-config will always be copied to the startup-config and the modified flag will always be set to True. If the argument is set to modified, then the running-config will only be copied to the startup-config if it has changed since the last save to startup-config. If the argument is set to never, the running-config will never be copied to the startup-config
src
(added in 2.2)
 no
The src argument provides a path to the configuration file to load into the remote system. The path can either be a full system path to the configuration file if the value starts with / or relative to the root of the implemented role or playbook. This argument is mutually exclusive with the lines and parents arguments. It can be a Jinja2 template as well.
