short_description: Manage EdgeOS configuration on remote device
|
||||||
|
description:
|
||||||
|
- This module provides configuration file management of EdgeOS
|
||||||
|
devices. It provides arguments for managing both the
|
||||||
|
configuration file and state of the active configuration. All
|
||||||
|
configuration statements are based on `set` and `delete` commands
|
||||||
|
in the device configuration.
|
||||||
|
notes:
|
||||||
|
- Tested against EdgeOS 1.9.7

- The C(src) argument specifies the path to the source config

bracket format or set format. The source file can include

- The C(match) argument controls the method used to match

desired config is matched against the active config and the
|

- The C(config) argument specifies the base configuration to use
