nxos_config - Manage Cisco NXOS configuration sections

New in version 2.1.

Synopsis

  • Cisco NXOS configurations use a simple block indent file syntax for segmenting configuration into sections. This module provides an implementation for working with NXOS configuration sections in a deterministic way. This module works with either CLI or NXAPI 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.
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 startup
  • startup
  • intended
  • running
When using the ansible-playbook --diff command line argument the 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.
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.
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.
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.
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 nxapi transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
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 nxapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
provider
no
Convenience method that allows all nxos arguments to be passed as a dict object. All constraints (required, choices, etc) must be met either by individual arguments or values in this dict.
replace
no lineo
  • line
  • block
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 comparison.

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.
ssh_keyfile
no
Specifies the SSH key to use to authenticate the connection to the remote device. This argument is only used for the cli transport. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
timeout
(added in 2.3)
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. NX-API can be slow to return on long-running commands (sh mac, sh bgp, etc).
transport
yes cli
Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or nxapi.
use_ssl
no
  • yes
  • no
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
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 nxapi 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.
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 nxapi, this value is ignored.
