This Ansible playbook automates the process of backing up device configurations in your network inventory. It is designed to work with Catalyst Center Release version 2.3.7.6 or later.

Key Points:

Supported Catalyst Center Version:

2.3.7.6 and above

Workflow Definition:

device_configs_backup_details specifies the devices and their details to include in the backup.

Full Workflow Specification:

Refer to the official documentation for detailed information on defining workflows: https://galaxy.ansible.com/ui/repo/published/cisco/dnac/content/module/device_configs_backup_workflow_manager

Procedure

  1. Prepare your Ansible environment:

Install Ansible if you haven't already Ensure you have network connectivity to your Catalyst Center instance. Checkout the project and playbooks: git@github.com:cisco-en-programmability/catalyst-center-ansible-iac.git

  1. Configure Host Inventory:

The host_inventory_dnac1/hosts.yml file specifies the connection details (IP address, credentials, etc.) for your Catalyst Center instance. Make sure the dnac_version in this file matches your actual Catalyst Center version.

The Sample host_inventory_dnac1/hosts.yml

catalyst_center_hosts:
    hosts:
        catalyst_center220:
            dnac_host: xx.xx.xx.xx.
            dnac_password: XXXXXXXX
            dnac_port: 443
            dnac_timeout: 60
            dnac_username: admin
            dnac_verify: false
            dnac_version: 2.3.7.6
            dnac_debug: true
            dnac_log_level: INFO
            dnac_log: true

  1. Generate your Input:

The workflows/device_config_backup/vars/device_config_backup_workflow_input.yml file should be configured with device details Refer to the full workflow specification for detailed instructions on the available options and their structure: https://galaxy.ansible.com/ui/repo/published/cisco/dnac/content/module/device_configs_backup_workflow_manager

  1. Validate Input (Recommended):

Validate the input with schema using yamale

yamale -s workflows/device_config_backup/schema/device_config_backup_workflow_schema.yml workflows/device_config_backup/vars/device_config_backup_workflow_input.yml

Example run:

  1. Collect device running configurations through Catalyst Center APIs.

ansible-playbook -i host_inventory_dnac1/hosts.yml workflows/device_config_backup/playbook/device_config_backup_workflow_playbook.yml --e VARS_FILE_PATH=../vars/device_config_backup_workflow_input.yml -vvvv

Important Notes:

  1. Ensure the Catalyst Center version is compatible.
  2. Carefully configure inventory and input variables.
  3. Validate input using yamale to prevent errors.
  4. Review execution logs for troubleshooting.
