- Configures a destination file to write the source template or config
updates to. The path to the destination file can either be a full
path on the Ansible control host or a relative path from the
playbook or role root directory. This will, by default, overwrite any
previously created file. See I(append) to change the behavior.
- When the I(dest) argument is used, the output from processing the

device. If theI(dest) argument is omitted, then the configuration
is written to the device.

- 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 I(src) into the device
without first checking if already configured.
- Note this argument should be considered deprecated. To achieve
the equivalient, set the match argument to none. This argument
will be removed in a future release.
