Information About Transport Layer Security Tunnel Support
The Cisco Catalyst 9800 Series Wireless Controller requires direct access to a public cloud to implement the teleworker solution using Cisco OfficeExtend Access Points (OEAPs). With the introduction of Transport Layer Security (TLS) tunnel support from Cisco IOS XE Amsterdam 17.3.2 onwards, the controller can now reach a public cloud automatically. This helps Digital Network Architecture (DNA) Center on Cloud to establish TLS communication channels with the controller to perform monitor and manage of wireless solutions.
The TLS connection ensures that the configuration and telemetry are reliably and securely communicated between the controller and the Digital Network Architecture (DNA) on Cloud. The TLS tunnel encrypts all the data that is sent over the TCP connection. The TLS tunnel provides a more secure protocol across the internet. After the controller discovery, the Cisco DNA Center on Cloud uses Cisco DNA Assurance and Automation features to manage the controller centrally.
Cisco Plug and Play
The Cisco Plug and Play solution is a converged solution that provides a highly secure, scalable, seamless, and unified zero-touch deployment experience.
The Cisco Plug and Play (PnP) agent is an embedded software component that is present in all the Cisco network devices that support simplified deployment architecture. The PnP agent understands and interacts only with a PnP server. The PnP agent, using DHCP, DNS, or other such methods, tries to acquire the IP address of the PnP server with which it wants to communicate. After a server is found and a connection is established, the agent communicates with the PnP server to perform deployment-related activities.
For more information on Cisco Plug and Play, see the Cisco Plug and Play Feature Guide.
The Transport Layer Security Tunnel (TLS) over PnP feature is supported on the following controllers:
Cisco Catalyst 9800-80 Wireless Controller
Cisco Catalyst 9800-40 Wireless Controller
Cisco Catalyst 9800-L Wireless Controller
