NP7 Host Protection Engine (HPE) support
The NP7 host protection engine (HPE) uses NP7 processors to protect the FortiGate CPU from excessive amounts of ingress traffic, which typically occurs during DDoS attacks or network problems (for example an ARP flood due to a network loop). You can use the HPE to prevent ingress traffic received on data interfaces connected to NP7 processors from overloading the FortiGate CPU. For information about HPE, see NP7 Host Protection Engine (HPE).
On the FortiGate 7000F, the NP7 processors in the FPM-7620Fs support HPE protection. The NP7 processors in the FIMs are used for SLBC load balancing. For more information, see:
