In a 1+1 High Availability (HA) deployment, FortiNAC-F supports two primary methods for management access: individual IP addresses or a Shared IP Address (also known as a Virtual IP or VIP). The Shared IP option is part of a Layer 2 HA design, which simplifies administration by providing a single URL or IP that always points to whichever appliance is currently in the "Active" or "In Control" state.
For a Shared IP configuration to function correctly, the Primary and Secondary administrative interfaces (port1) must be on the same subnet. This requirement exists because the Shared IP is a logical address that is dynamically assigned to the physical interface of the active unit. Since only one unit can own the IP at a time, both units must reside on the same broadcast domain (Layer 2) to ensure that ARP requests for the Shared IP are correctly answered and that the gateway remains reachable regardless of which unit is active. If the appliances were on different subnets (a Layer 3 HA design), a shared IP could not be used because it cannot "float" across different network segments; instead, administrators would need to manage each unit via its unique physical IP or use a FortiNAC Manager.
"For L2 HA configurations, click the Use Shared IP Address checkbox and enter the Shared IP Address information... If your Primary and Secondary Servers are not in the same subnet, do not use a shared IP address. The shared IP address moves between appliances during a failover and recovery and requires both units to reside on the same network." - FortiNAC-F High Availability Reference Manual: Shared IP Configuration.

The integration between FortiNAC-F and Mobile Device Management (MDM) platforms (such as Microsoft Intune, VMware Workspace ONE, or Jamf) is a critical component for providing visibility into mobile assets that do not connect directly to the managed infrastructure via standard wired or wireless protocols.
According to the FortiNAC-F MDM Integration Guide, the communication between the FortiNAC-F appliance and the MDM server is handled through REST API calls. FortiNAC-F acts as an API client, periodically polling the MDM server to retrieve device metadata, compliance status, and ownership information. If communication is failing, it is most likely because the API credentials (Client ID/Secret) are incorrect, the MDM's API endpoint is unreachable from the FortiNAC-F service port, or the SSL certificate presented by the MDM is not trusted by the FortiNAC-F root store.
While SSH (B) is used for switch CLI management and the Security Fabric (A) uses proprietary protocols for FortiGate synchronization, neither is the primary vehicle for MDM data exchange. SOAP API (D) is an older protocol that has been largely replaced by REST in modern FortiNAC integrations.
"FortiNAC integrates with MDM systems by utilizing REST API communication to query the MDM database for device information. To establish this link, administrators must configure the MDM Service Connector with the appropriate API URL and authentication credentials. If the 'Test Connection' fails, verify that the FortiNAC can reach the MDM provider via the REST API port (usually HTTPS 443)." - FortiNAC-F Administration Guide: MDM Integration and Troubleshooting.

The FortiNAC-F Manager (FortiNAC-M) is designed as a centralized management platform for large-scale distributed environments where multiple FortiNAC-F Control and Application (CA) appliances are deployed across different sites. According to the FortiNAC-F Manager Administration Guide, the deployment of a Manager simplifies administrative overhead in three specific ways:
First, it provides Global Version Control (B). The Manager serves as a central repository for firmware and software updates, allowing administrators to push specific versions to all managed CAs simultaneously, ensuring consistency across the entire fabric. Second, it enables Pooled Licenses (D). Instead of purchasing and managing individual licenses for every CA, licenses are centralized on the Manager. The Manager then distributes these licenses to the CAs as needed based on their host counts. This "floating" license model optimizes cost and prevents individual sites from running out of capacity while others have excess. Third, it offers Global Visibility (E). The Manager aggregates host and device data from every managed CA into a single console. This "single pane of glass" allows an administrator to search for a specific MAC address or user across the entire global organization without logging into individual servers.
While the Manager can assist with configuration templates, authentication security policies (C) and infrastructure modeling (A) are still predominantly managed at the local CA level to ensure site-specific logic and performance.
"The FortiNAC Manager provides a central management console for multiple FortiNAC-F servers (CAs). Key benefits include: * License Management: Licenses are pooled on the Manager and allocated to managed CAs as needed. * Software Management: Firmware updates can be centrally managed and pushed to all CAs from the Manager. * Centralized Monitoring: Provides a global view of all hosts, adapters, and events across the entire managed environment." - FortiNAC-F Manager Administration Guide: Overview and Benefits.

The N+1 High Availability (HA) architecture was introduced in FortiNAC-F version 7.6 to provide a more scalable and flexible redundancy model compared to the traditional 1+1 active/passive setup. In an N+1 configuration, a single secondary (standby) appliance can provide coverage for multiple primary (active) Control and Application (CA) appliances.
To set up an N+1 HA cluster, there are two fundamental structural requirements:
A FortiNAC-F Manager (FortiNAC-M): Unlike standard 1+1 HA, which can be configured directly between two CAs, N+1 management is centralized. The FortiNAC-M acts as the orchestrator that manages the failover groups, monitors the health of the primaries, and coordinates the promotion of the secondary server if a primary fails.
A FortiNAC-F device designated as a Secondary: The cluster must have one appliance explicitly configured with the Secondary failover role. This device remains in a standby state, receiving database replications from all N primaries in its group until it is called upon to take over the functions of a failed unit.
While a cluster can support multiple primaries (D), it does not strictly require "at least two" to function as an N+1 group; it simply requires N primaries (where N ≥ 1). Additionally, N+1 is typically a Layer 3 managed solution via the Manager, meaning it does not mandate a "dedicated VLAN" for synchronization like some Layer 2 HA deployments.
"In FortiNAC-F 7.6, FortiNAC-M functions as a manager to manage the N+1 Failover Groups... enabling N+M high availability for CAs. To create an N+1 Failover group, you should add the secondary CA to the FortiNAC-M first, then add the primary CAs. The secondary CA is designed to take over the functionality of any single failed primary component." - FortiNAC-F 7.6.0 N+1 Failover Reference Manual.

Comprehensive and Detailed 250 to 300 words each Explanation with Exact Matched Extract from FortiNAC-F Administrator library and documentation for current versions (including F 7.2, 7.4, and 7.6) documents:
In FortiNAC-F, the expiration of a guest or contractor account is determined by the configuration settings within the Account Creation Wizard and the associated Guest/Contractor Template. While a template can define a default "Account Duration" (as seen in the 12-hour setting in the second exhibit), the Account Creation Wizard allows an administrator to manually specify or override the start and end parameters for a specific user session.
According to the FortiNAC-F Administration Guide regarding guest management, the Account End Date field in the creation wizard is the definitive timestamp for when the account object will be disabled or deleted from the system. In the provided exhibit (Account Creation Wizard), the administrator has explicitly set the Account Start Date to 2025/09/12 08:00:00 and the Account End Date to 2025/09/13 17:00:00.
Even though the template indicates an "Account Duration" of 12 hours, this value typically serves as a pre-populated default. When a manual date and time are entered into the wizard, those specific values take precedence for that individual account. The account will remain active and valid until 5:00 PM (17:00:00) on the following day, 2025/09/13. It is also important to note the "Login Availability" from the template (8:00 AM - 7:00 PM); while the account exists until the 13th at 17:00:00, the user would only be able to authenticate during the active hours defined by the login schedule on both days.
"When creating an account, the administrator can select a template to provide default settings. However, specific values such as the Account End Date can be modified within the Account Creation Wizard. The date and time specified in the 'Account End Date' field determines the absolute expiration of the account. Once this time is reached, the account is moved to an expired state and the user's network access is revoked." - FortiNAC-F Administration Guide: Guest and Contractor Account Management.
