This technique is known as the Forward Error Correction technique. It is important to keep FEC settings the same on both FortiGate and switch sides, otherwise, ports will not get up due to mismatch. The receiver is then able to detect certain errors that came from the sending the data. Forward Error Correction Three common methods for error detection: I Parity I Checksum I Cyclic . If more than one tunnel is available, duplicated packets will be sent over the tunnel with the best parameters. Network Security. (Choose two.) Adaptive Forward Error Correction | FortiGate / FortiOS 7.2.4 After each install, I need to connect to the FortiGate and add "set forward error correction disabled" to both of the ports, and the comm restores. The plethora of vendors that resell hardware but have zero engineering knowledge resulting in the wrong hardware or configuration being deployed is a major pet peeve of Michael's. As packet loss increases, the number of redundant packets sent can rise accordingly. An FEC profile is configured to adaptively increase redundant levels if the link quality exceeds a 10% packet loss threshold, or the bandwidth exceeds 950 Mbps. Six new parameters are added to the IPsec phase1-interface settings: Enable/disable Forward Error Correction for ingress IPsec traffic (default = disable). The number of base Forward Error Correction packets (1 - 100, default = 20). Fortinet Community Knowledge Base FortiGate If your FortiGate is NPU capable, disable npu-offload in your phase1 configurations: For example, a customer has two ISP connections, wan1 and wan2. The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.. Technical Tip: changes in Forward Error Correct (F - Fortinet Community In this example, an IPsec tunnel is configured between two FortiGates that both have FEC enabled. Following are some NSE7_SDW-6.4 Exam Questions for Review. Re: Show Forward Error Correction (FEC) in FAZ reporting 08:14 AM, The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.. Forward Error Correction - Cisco On FortiGate A, apply the FEC mappings on vd1-p1: The FEC base and redundant values are used when the link quality has not exceeded the limits specified in the FEC profile mapping. FEC is enabled on vd1-p1, and health-check works on vd1-p1. The mechanism sends out x number of redundant packets for every y number of base packets. Configure FEC on each VPN interface to lower packet loss ratio by re-transmitting the packets using its backend algorithm.
