cnos_config – Manage Lenovo CNOS configuration sections

New in version 2.6.

Synopsis

  • Lenovo CNOS configurations use a simple block indent file syntax for segmenting configuration into sections. This module provides an implementation for working with CNOS configuration sections in a deterministic way.

Parameters

Parameter Choices/Defaults Comments
admin
boolean
    Choices:
  • no ←
  • yes
Enters into administration configuration mode for making config changes to the device.
after
-
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
boolean
    Choices:
  • no ←
  • yes
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. If the backup_options value is not given, the backup file is written to the backup folder in the playbook root directory. If the directory does not exist, it is created.
backup_options
dictionary
added in 2.8
This is a dict object containing configurable options related to backup file path. The value of this option is read only when backup is set to yes, if backup is set to no this option will be silently ignored.
dir_path
path
This option provides the path ending with directory name in which the backup configuration file will be stored. If the directory does not exist it will be first created and the filename is either the value of filename or default filename as described in filename options description. If the path value is not given in that case a backup directory will be created in the current working directory and backup configuration will be copied in filename within backup directory.
filename
-
The filename to be used to store the backup configuration. If the the filename is not given it will be generated based on the hostname, current time and date in format defined by <hostname>_config.<current-date>@<current-time>
before
-
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.
comment
-
Default:
"configured by cnos_config"
Allows a commit description to be specified to be included when the configuration is committed. If the configuration is not changed or committed, this argument is ignored.
config
-
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 config argument allows the implementer to pass in the configuration to use as the base config for comparison.
lines
-
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.

aliases: commands
match
-
    Choices:
  • 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
-
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.
replace
-
    Choices:
  • 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.
src
-
Specifies the source path to the file that contains the configuration or configuration template to load. The path to the source file can either be the full path on the Ansible control host or a relative path from the playbook or role root directory. This argument is mutually exclusive with lines, parents.

Notes

Note

  • Tested against CNOS 10.9.1
