Overview
This section provides an overview of how closed-loop automation facilitates software image provisioning and management between Catalyst Center and ServiceNow, including the approval and notification process for change requests.
You can use closed loop automation to manage software images (SWIM) between Catalyst Center and ServiceNow. With closed-loop automation, you configure the provisioning of software device images in Catalyst Center. This configuration information is communicated directly from Catalyst Center to ServiceNow as an immediate or scheduled change request. The ServiceNow administrator reviews the change request and approves or rejects it in ServiceNow. The acceptance or rejection of the change request is communicated back to Catalyst Center.
After receiving an approved change request from ServiceNow, Catalyst Center updates the software either immediately or at its scheduled time.
After Catalyst Center successfully performs the software update, it sends a task completion notification to ServiceNow. If the software update fails, it sends a task failure notification to ServiceNow. You can then perform the software update manually in Catalyst Center.
If the SWIM provisioning is stopped by the user in Catalyst Center during this process, a task termination notification is sent to ServiceNow.
Ensure that the Cisco Catalyst app (version 2.2.0) is installed in the ServiceNow instance. Complete these steps to enable SWIM closed loop automation between Catalyst Center and ServiceNow:
-
Review the requirements to ensure that the prerequisites for this feature have been met. See SWIM closed loop automation requirements.
-
Review the SWIM closed loop automation workflow to ensure that the required Catalyst Center admin and ServiceNow admin tasks are done for this feature. See SWIM closed loop automation workflow.
