Review the following requirements before beginning the Cisco DNA Center appliance installation.
This version of DNA Center allows only a single-host deployment for your network. Multi-host deployment is not supported.
Networking Interface Requirements
In a production installation, you must connect the DNA Center appliance's network ports to your network. Cisco recommends the following cable connections:
First 10Gb port in the VIC: Connect to an access switch with connections to the enterprise network.
First embedded 1Gb interface: Connect to the dedicated management network (if it exists; Cisco recommends that you create one if it does not already exist).
The following connections are either optional or reserved for future use:
Second 10Gb port in the VIC: Reserved for future intra-cluster connections (clustering is not supported in this release).
1Gb Ethernet dedicated out-of-band management port: Reserved for OOB management of the appliance chassis.
Second embedded 1Gb interface: Optional. You can connect this interface to any isolated network with a static route. However, Cisco recommends that you leave it unconfigured.
For a diagram showing these ports, see the back-panel illustration in Cisco DNA Center Appliance Front and Rear Panels.
IP Address Requirements
Before beginning the installation, ensure that your network has sufficient IP addresses available to assign to each of the DNA Center appliance ports you plan on using. You will need a minimum of two addresses: one for the connection to the enterprise network, and one for the 1Gb OOB management port. You will need three if you have a dedicated management network and plan to connect the appliance to the first embedded 1Gb interface, and four if you will also use the second embedded 1Gb inteface for a static-route connection.
Internet Access Requirements
By default, DNA Center is configured to send product-improvement and usage information to Cisco via the internet. If you do not wish to provide internet connectivity for this purpose, or do not want to participate in the Cisco product improvement program, you can opt out by disabling the telemetry collection parameter in the installed DNA Center's System Settings.
To disable the telemetry collection parameter, log into DNA Center and select . Uncheck the Telemetry Collection checkbox, then click Update.
