 Cisco ISE is a comprehensive solution that provides authentication, authorization, and accounting (AAA) services, as well as posture, profiling, and guest access features. These are some of the key features that differentiate Cisco ISE from other RADIUS and NAC products in the market.

• Ability to authenticate and authorize users and endpoints: Cisco ISE supports various authentication methods and protocols, such as 802.1X, MAB, WebAuth, EAP, PEAP, EAP-TLS, and TEAP. Cisco ISE also integrates with various identity sources, such as Active Directory, LDAP, RADIUS, SAML, and Azure AD. Cisco ISE can enforce granular and dynamic policies based on the identity and context of the users and endpoints, such as device type, location, posture, and time. Cisco ISE can also leverage TrustSec and SGTs to provide software-defined segmentation and micro-segmentation12.
• BYOD provides auto configuration of endpoints: Cisco ISE supports BYOD (Bring Your Own Device) scenarios, where users can register and onboard their personal devices to the network. Cisco ISE provides a self-service portal and a native supplicant provisioning tool that can automatically configure the endpoints with the required certificates, profiles, and settings. Cisco ISE can also apply different policies for corporate and personal devices, and integrate with MDM (Mobile Device Management) solutions to enforce compliance and security34.
• Guest access and guest lifecycle management functionality: Cisco ISE provides a comprehensive guest access solution that allows administrators and sponsors to create and manage guest accounts, and assign different access levels and privileges to guests. Cisco ISE also provides a customizable guest portal that can support various authentication methods, such as social media login, SMS, email, or self-registration. Cisco ISE can also monitor and audit the guest activities and sessions, and enforce expiration and revocation policies .

Syslog, FNF (Flexible NetFlow), and SNMP (Simple Network Management Protocol) are three technologies that can be deployed to gather data and provide insight into the network performance, health, and behavior. Syslog is a standard protocol for logging messages from network devices, such as routers, switches, firewalls, and servers. Syslog messages can be sent to a centralized server for analysis, correlation, and alerting. FNF is a Cisco technology that captures and exports information about network flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. FNF can be used to monitor network traffic patterns, identify anomalies, and optimize network resources. SNMP is a protocol that allows network devices to communicate with management systems, such as Cisco DNA Center. SNMP can be used to collect statistics, configuration, and status information from network devices, as well as to send commands and notifications. SNMP can help network administrators to troubleshoot, configure, and manage their network devices remotely. References: Cisco DNA Center User Guide, Release 1.3.1.0 - Monitor the Network 1, Cisco DNA Center User Guide, Release 1.3.1.0 - Configure Flexible NetFlow 2, Cisco DNA Center User Guide, Release 1.3.1.0 - Configure SNMP 3

A centralized SD-Access design is where a single fabric domain spans across the main site and all branch sites over the WAN. This design has some challenges, such as:

• Since the traffic is encapsulated in VXLAN headers, SD-WAN features such as application-aware routing, QoS, and security policies cannot be applied to the traffic based on the original IP headers. This means that the SD-WAN controller cannot optimize or route the traffic based on the application or user identity. The traffic is treated as a single class of service across the WAN.
• The centralized design also introduces a single point of failure and a potential bottleneck at the main site, where the border nodes and the control plane nodes are located. If the main site goes down or the WAN link fails, the branch sites will lose connectivity to the fabric domain and the external networks.
• The centralized design also requires a high bandwidth and low latency WAN connection between the main site and the branch sites, which may not be feasible or cost-effective for some scenarios.
