L2 and L3 Network Examples

This document discusses the network types available when configuring FortiNAC, including layer 2 and layer 3 networks. Layer 2 networks use switching and 802.1Q tagging for isolation networks. Layer 3 networks route isolation networks and are required for high availability configurations with redundant servers on different subnets.

Overview
This document explains the Network Types available when configuring FortiNAC. For more
information on appliance configuration, see the appropriate installation guide in the Fortinet
Document Library.

There are two network type options:


• Layer 2 network: Isolation networks are switched to the FortiNAC eth1 interface.
802.1Q tags are configured for the corresponding isolation VLANs, and eth1 IP addresses
are within those isolation networks. See Layer 2 for illustrations

• Layer 3 network: Isolation networks are routed to the FortiNAC eth1 interface. See
Layer 3 for illustrations

Important: In a High Availability environment with L3 configuration (redundant


FortiNAC servers on different subnets and do not use a shared IP address), the Layer 3
network option is required. L3 High Availability configurations are not supported with
Layer 2 Isolation settings.
