Connected to CSSM Through a Controller
When you use a controller to manage a product instance, the controller connects to CSSM, and is the interface
for all communication to and from CSSM. The supported controller for Cisco Catalyst Access, Core, and
Aggregation Switches is Cisco DNA Center.
Overview
If a product instance is managed by Cisco DNA Center as the controller, the product instance records license
usage and saves the same, but it is the Cisco DNA Center that initiates communication with the product
instance to retrieve RUM reports, report to CSSM, and return the ACK for installation on the product instance.
All product instances that must be managed by Cisco DNA Center must be part of its inventory and must be
assigned to a site. Cisco DNA Center uses the NETCONF protocol to provision configuration and retrieve
the required information from the product instance - the product instance must therefore have NETCONF
enabled, to facilitate this.
In order to meet reporting requirements, Cisco DNA Center retrieves the applicable policy from CSSM and
provides the following reporting options:
• Ad hoc reporting: You can trigger an ad hoc report when required.
• Scheduled reporting: Corresponds with the reporting frequency specified in the policy and is automatically
handled by Cisco DNA Center.
Ad hoc reporting must be performed at least once before a product instance is eligible for scheduled reporting.
Note
The first ad hoc report enables Cisco DNA Center to determine the Smart Account and Virtual Account to
which subsequent RUM reports must be uploaded. You will receive notifications if ad hoc reporting for a
product instance has not been performed even once.
Cisco DNA Center also enables you to install and remove SLAC for export-controlled licenses. Since all
available licenses on Cisco Catalyst Access, Core, and Aggregation Switches are unenforced licenses, SLAC
installation and removal do not apply.
A trust code is not required.
