FortiNAC L2/L3 polling

[ByteHaven]

Hello FNAC admins,

Does the L2 and L3 polling in FortiNAC depend on the network type selected (Layer 2 or Layer 3)? For example, if I choose Layer 2 as the network type, will only L2 polling be used?

Why not enable both?

That doesnt really answer my question, I wanna know if choosing FortiNAC to work with Layer 2 or Layer 3 network type in the config wizard, has anything to do with L2/L3 polling

No, they are not related. The deployed network type determines how FNAC handles end-host isolation traffic.
L2 polling must be enabled on network devices that store host information in the MAC address table, and L3 polling must be enabled on devices that store host information in the ARP table. Typically, both are required for L3 switches or FortiGate devices managing FortiSwitches (FSW) and FortiAPs (FAP).
