 ISE automation BYOD flow is a process that allows users to self-enroll their devices to the network without requiring IT intervention. The process consists of three main functions: certificate enrollment, device registration, and supplicant provisioning.

• Certificate enrollment is the function that allows users to obtain a digital certificate from a certificate authority (CA) for their devices. This certificate is used to authenticate the device to the network and provide secure communication. ISE supports different CA options, such as Microsoft CA, Cisco ISE CA, or third-party CA .
• Device registration is the function that allows users to register their devices to the network and associate them with their identity. This enables ISE to apply policies based on the device type, ownership, and posture. ISE supports different device registration methods, such as portal-based, API-based, or bulk import .
• Supplicant provisioning is the function that allows users to install and configure a network access client (supplicant) on their devices. This client is used to connect to the network using the appropriate protocols and settings. ISE supports different supplicant provisioning methods, such as native supplicant, Cisco Network Setup Assistant (NSA), or Cisco AnyConnect Secure Mobility Client (AnyConnect) .

 SD-Access Fabric is a network architecture that uses three key technologies to create a virtual overlay network on top of the physical underlay network. These technologies are:

• VXLAN: Virtual Extensible LAN is a tunneling protocol that encapsulates Layer 2 frames in UDP packets and transports them over an IP network. VXLAN enables the creation of large-scale virtual networks that span multiple Layer 3 domains. VXLAN is used in SD-Access Fabric to carry user traffic between different fabric nodes and to provide network segmentation based on virtual network identifiers (VNIs).
• TrustSec: Cisco TrustSec is a security framework that uses software-defined segmentation to enforce granular access policies based on the identity and context of users, devices, and applications. TrustSec uses scalable group tags (SGTs) to classify endpoints into logical groups and applies security policies based on the source and destination SGTs. TrustSec is integrated with SD-Access Fabric to provide micro-segmentation within a virtual network and to simplify policy management across the fabric.
• LISP: Locator/ID Separation Protocol is a routing protocol that decouples the endpoint identity (EID) from its location (RLOC) in the network. LISP uses two types of devices: ingress tunnel routers (ITRs) and egress tunnel routers (ETRs) to map EIDs to RLOCs and to encapsulate and decapsulate packets. LISP is used in SD-Access Fabric to provide control plane functions, such as endpoint registration, discovery, and mobility. LISP also enables seamless integration of SD-Access Fabric with external networks, such as the Internet, WAN, or data center.

The other options, OTV, RSVP, and MPLS, are not used in SD-Access Fabric. OTV is another tunneling protocol that extends Layer 2 connectivity across Layer 3 domains, but it is not compatible with VXLAN. RSVP is a signaling protocol that reserves network resources for quality of service (QoS), but it is not required for SD-Access Fabric. MPLS is a packet-switching technology that labels packets and forwards them based on label switching routers (LSRs), but it is not involved in SD-Access Fabric. References := : Cisco SD-Access Solution Design Guide (CVD) - Cisco1, Cisco Software-Defined Access - Cisco Software-Defined Access Solution Overview2

A Digital Network is a network that is based on the Cisco Digital Network Architecture (Cisco DNA), which is an open and extensible, software-driven network architecture designed to rapidly deliver services that enable IT to innovate faster, reduce costs and complexity, lower risk, and comply with regulatory requirements1. A key function of a Digital Network is centralized provisioning, which allows IT to automate the deployment and configuration of network devices and services using a single platform, such as the Cisco DNA Center2. Centralized provisioning simplifies network management, reduces human errors, and accelerates network changes.

 DNA Center is the central point of management for SD-Access. It provides a graphical user interface (GUI) to design, provision, and monitor the SD-Access fabric. DNA Center also offers various service applications that leverage the network data and analytics to provide insights, automation, and assurance for the network and the applications running on it. DNA Center does not perform the functions of identifying and authenticating endpoints, which are handled by ISE; nor does it act as the point of exchange of reachability and policy for two domains, which are the roles of the border nodes and the control plane nodes; nor does it maintain a database of endpoint IDs to fabric edge nodes, which is the function of the LISP mapping system. References:

According to the Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers document1, the three Cisco recommendations on “How to Win” are:

• Explain support for 3rd party network devices: Cisco ISE can integrate with more than 60 third-party solutions that span across security and network portfolios. This enablesCisco ISE to leverage the information and capabilities of these solutions to enhance the identity and access management, network visibility and segmentation, threat detection and response, and policy enforcement of the network. By explaining this support, the customer can see the value and flexibility of Cisco ISE in their existing or heterogeneous network environment2.
• Explain architectural advantage of holistic Cisco solution: Cisco ISE is part of the Cisco Digital Network Architecture (DNA), which is a comprehensive and open platform that provides end-to-end network automation, assurance, security, and analytics. By explaining the architectural advantage of the holistic Cisco solution, the customer can see how Cisco ISE works seamlessly with other Cisco DNA components, such as Cisco DNA Center, Cisco SD-Access, Cisco SD-WAN, Cisco TrustSec, and Cisco Stealthwatch, to deliver a unified and consistent network experience across wired, wireless, and cloud domains3.
• Talk about Cisco’s focus on Security and integration with StealthWatch, Sourcefire, WSA, vulnerability scanner to make smarter policy decisions: Cisco ISE is a core component of the Cisco security portfolio, which provides comprehensive and integrated security solutions for the network. By talking about Cisco’s focus on security and integration with other security products, such as StealthWatch, Sourcefire, WSA, and vulnerability scanner, the customer can see how Cisco ISE can provide enhanced visibility, threat detection, and policy enforcement for the network. For example, Cisco ISE can use the data from StealthWatch to identify anomalous or malicious behavior of the endpoints and apply appropriate network access policies based on the threat level4.

The other options, show case Cisco portfolio or ISE feature set during PoC and demonstrate complex policy flows, rather show case Wizards and enhanced context visibility, are not Cisco recommendations on “How to Win”. Showing case Cisco portfolio or ISE feature set during PoC is a general best practice, but not a specific recommendation for winning the customer. Demonstrating complex policy flows, rather than showing case Wizards and enhanced context visibility, is a counterproductive approach, as it can confuse or overwhelm the customer with technical details, rather than highlighting the benefits and simplicity of Cisco ISE. References := : 2: Cisco Identity Services Engine Administrator Guide, Release 2.7 - ISE Security Ecosystem Integration Guides [Cisco Identity Services Engine] - Cisco2, 1: Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers1, 3: Cisco Identity Services Engine - Cisco3, 4: Cisco Identity Services Engine Administrator Guide, Release 2.7 - Stealthwatch Integration [Cisco Identity Services Engine] - Cisco4
