Introduction

In network environments like dorm rooms, and other multi-dwelling buildings, the network is shared among the users. Today, users cannot deterministically discover and limit access to “their devices” on a shared network. Due to the inherent nature of devices that use link local multicast to broadcast their services, devices which belong to other users can be taken control of and used for other purposes. This results in poor user experience in such environments.

Cisco® User Defined Network is a Cisco network solution available through Cisco DNA Center, which provides secure and remote onboarding of client devices and allows IT staff to give each user oversight of his or her very own network partition. This enables a personal network experience in the shared network environment.

Users can remotely and securely register their personal devices on their own from home or anywhere using the intuitive Cisco User Defined Network mobile app. Once the devices have been registered and the user arrives at the shared network location, their wireless devices connect to the shared network and are placed into their personal network.

Cisco User Defined Network grants both device security and control, allowing end users the choice of who can connect to their network. The Cisco User Defined Network solution also gives end users the ability to invite trusted users, such as friends, to their personal network through the mobile app so that they can collaborate and share their devices with them.

As the solution is enabled in shared networks, users are unable to see other users’ devices in the network. Incidentally, unlike other solutions, Cisco User Defined Network works with mDNS, UPnP, and other link local multicast or broadcast protocols. IT staff also has the option of disabling unicast communication between two user defined networks if they choose to do so through Cisco DNA Center.

Solution Components

Cisco Catalyst 9800

Cisco Catalyst 9800 provides enforcement of User Defined Network policies. Cisco User Defined Network is supported with central switching mode on Catalyst 9800-80, Catalyst 9800-40, Catalyst 9800-L and Catalyst 9800-CL.

Cisco User Defined Network solution is supported on IOS XE 17.3.1 or above.

Cisco Catalyst 9100 Access Points or Cisco Aironet ®802.11ac Wave 2 access points

Cisco User Defined Network is supported on Cisco Catalyst 9100, Cisco Aironet® 1800, 2800, 3800, and 4800 Access Points.

Cisco DNA Center

Cisco DNA Center provides a single point to IT staff to enable the Cisco User Defined Network solution with a single end to end workflow. Admins can select and decide where they want to enable the solution, which SSIDs they want to enable the solution and when they want to enable the solution. Cisco DNA Center also provides granular visibility to end user’s User Defined Networks through Client 360 view on Assurance. Cisco User Defined Network solution is supported on Cisco DNA Center 2.1.1 and above.

Identity Services Engine

Identity Service Engine (ISE) provides point of authentication and authorization for end users to connect to the network. Cisco User Defined Network solution is supported on ISE 2.7.1 or above.

Cisco User Defined Network Cloud Service

Included as part of Cisco DNA Advantage license, Cisco UDN Cloud Service enables users to register their devices from anywhere they want and anytime they want. It allows IT staff to connect their Active Directory to define users for which the solution will be enabled. IT staff will also get visibility and rich insights into User Defined Network solution operation with a dashboard.

Cisco UDN Mobile App

Available both on iOS and Android, Cisco UDN mobile app provides end users with option to register their devices from anywhere and anytime. Users can use multiple options available in the mobile app to register their devices. Mobile App also shows notifications and provides visibility of user’s own devices and guest’s devices which are part of their user defined network. Users can also invite guests (their friends and trusted users which have their own UDN Mobile App) to their User Defined Network through Mobile App for sharing their devices and collaboration.

Scale

Cisco User Defined Network solution scale varies as per the deployment options of the Catalyst 9800 controller.

Cisco Catalyst 9800-80

Up to 64,000 unique User Defined Networks per controller

Cisco Catalyst 9800-40

Up to 32,000 unique User Defined Networks per controller

Cisco Catalyst 9800-L

Up to 5,000 unique User Defined Networks per controller

Cisco Catalyst 9800-CL

10,000, 32,000 or 64,000 unique User Defined Networks per controller

Overall, User Defined Networks are supported across multiple controllers depending on deployment scenario.

Licensing

Cisco User Defined Network solution requires Cisco DNA Advantage with ISE plus ala carte licenses or available with Cisco DNA Premier licensing bundle to enable the solution.
