short_description: Manage Cisco NSO configuration and service synchronization.
description:
- This module provides support for managing configuration in Cisco NSO and
can also ensure services are in sync.
requirements:
- Cisco NSO version 3.4.12 or higher, 4.2.7 or higher,
4.3.8 or higher, 4.4.3 or higher, 4.5 or higher.
author: "Claes Nästén (@cnasten)"
options:
data:
description: >
NSO data in format as | display json converted to YAML. List entries can
be annotated with a __state entry. Set to in-sync/deep-in-sync for
services to verify service is in sync with the network. Set to absent in
list entries to ensure they are deleted if they exist in NSO.
