To correct this traffic shaping issue on FortiGate, what configuration change must be made on which policy? B This traffic shaper drops traffic that exceeds the set limits. It uses six parameters in IPsec phase1/phase1-interface settings: For every fec-base number of sent packets, the tunnel will send fec-redundant number of redundant packets. This topic shows an SD-WAN with forward error correction (FEC) on VPN overlay networks. If fec-codec is set to xor the base and redundant packet values will not be updated. FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. Just found this video demonstration, pretty solid results it seems. 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. 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. 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. FortiOS 7.0.4 and up, FortiOS 7.2.0 and up. 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. For every fec-base number of sent packets, the tunnel will send fec-redundant number of redundant packets. For example, when there is no or low packet loss in the network, FEC can work on a low redundant level sending only one redundant packet for every 10 base packets. Does any one know how to build a FortiAnalyzer query for this? FEC is a technique used to control and correct errors in data transmission by sending redundant data across the VPN. FEC is far more complex then that. The intention is to apply FEC to UDP traffic that is passing through the VPN overlay, while allowing all other traffic to pass through without FEC. Forward Error Correction (FEC) is used to control and correct errors in data transmission by sending redundant data across the VPN in anticipation of dropped packets occurring during transit. FortiGate Cloud; Enterprise Networking. For Example, policies that allow the UDP based VoIP protocol can enable FEC, while TCP based traffic policies do not. The time before sending Forward Error Correction packets, in milliseconds (1 - 1000, default = 8). It is important to keep FEC settings the same on both FortiGate and switch sides, otherwise, ports will not get up due to mismatch. 10-29-2019 For example how many redundant packets are being sent. The DMZ interface and IPsec tunnel vd1-p1 are SD-WAN members. As packet loss increases, the number of redundant packets sent can rise accordingly. Send TCP and UDP traffic from PC1 to PC2, then check the sessions on FortiGate A: Non-FEC protected TCP traffic is offloaded, while FEC protected UDP traffic is not offloaded. Adaptive FEC considers link conditions and dynamically adjusts the FEC packet ratio: The FEC base and redundant packet relationship is dynamically adjusted based on changes to the network SLA metrics defined in the SD-WAN SLA health checks. Home FortiGate / FortiOS 7.0.0 New Features 7.0.0 Download PDF Forward error correction settings on switch ports Supported managed-switch ports can be configured with a forward error correction (FEC) state of Clause 74 FC-FEC for 25-Gbps ports and Clause 91 RS-FEC for 100-Gbps ports. 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.. Solution. The sender adds parts of the data again. This means that all traffic suffers a performance impact. In this example, a FortiSwitch 3032E that is managed by the FortiGate device is configured with Clause 74 FC-FEC on port 16.1 and Clause 91 RS-FEC on port 8. ECE2305: Forward Error Correction Basics Error Detection vs. 11-29-2022 This reduces unnecessary bandwidth consumption by FEC. FG22E1-2 (port25) # set forward-error-correction ?disable <----- Disable forward error correction (FEC).cl91-rs-fec <----- Reed-Solomon (FEC CL91).cl74-fc-fec <----- Fire-Code (FEC CL74). Please advice FortiGate FortiManager 430 0 On FortiGate A, create a policy to specify performing FEC on UDP traffic, and a policy for other traffic: On FortiGate A, configure FEC mapping to bind network SLA metrics and FEC base and redundant packets: The mappings are matched from top to bottom: packet loss greater than 10% with eight base and two redundant packets, and then uploading bandwidth greater than 950 Mbps with nine base and three redundant packets. Forward-looking statements in this report, including without limitation, statements related to the Company's plans, strategies, objectives, expectations, intentions and adequacy of resources, are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. On both FortiGates, enable FEC and NPU offloading on the IPsec tunnel vd1-p1: The VPN overlay member (vd1-p1) must be included in the health-check and configured as the higher priority member in the SD-WAN rule. Technical Tip: Forward Error Correction (FEC) - Fortinet Community FortiGate FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. As long as the receiver receives a subset of packets in the group (at-least N-1) and the parity packet, up to a single lost packet in the group can be recovered. The tunnel is an SD-WAN zone, and an SLA health-check is used to monitor the quality of the VPN overlay. 11-26-2020 On FortiGate A, check the health-check result and the corresponding FEC base and redundant packets: Because bandwidth-up is more than 950000kbps, base and redundant are set to 9 and 3: Make packet loss more than 10%, then check the health-check result and the corresponding FEC base and redundant packets again: Because packet loss is more than 10%, entry one in FEC mapping is first matched, and base and redundant are set to 8 and 2: Connecting FortiExplorer to a FortiGate

FEC is a technique used to control and correct errors in data transmission by sending redundant data across the VPN. For example how many redundant packets are being sent. The mechanism sends out x number of redundant packets for every y number of base packets. Forwarding Error Correction (FEC) is a method of obtaining error control in data transmission over an unreliable or noisy channel in which the source (transmitter) encodes the data in a redundant way using Error Correcting Code, and the destination (receiver) recognizes it and corrects the errors without requiring a retransmission. The DMZ interface and IPsec tunnel vd1-p1 are SD-WAN members. Email. As packet loss increases, the number of redundant packets sent can rise accordingly. For example, when there is no or low packet loss in the network, FEC can work on a low redundant level sending only one redundant packet for every 10 base packets. On both FortiGates, enable FEC and NPU offloading on the IPsec tunnel vd1-p1: The VPN overlay member (vd1-p1) must be included in the health-check and configured as the higher priority member in the SD-WAN rule.

It uses six parameters in IPsec phase1/phase1-interface settings: Enable/disable Forward Error Correction for ingress IPsec traffic (default = disable). 2. level 1. Edited By Forward Error Correction Three common methods for error detection: I Parity I Checksum I Cyclic . If fec-codec is set to xor the base and redundant packet values will not be updated. If fec-codec is set to xor the base and redundant packet values will not be updated.

Because FEC does not support NPU offloading, the ability to specify streams and policies that do not require FEC allows those traffic to be offloaded. Which two reasons make forward error correction (FEC) ideal to enable in a phase one VPN interface? Copyright 2023 Fortinet, Inc. All Rights Reserved. The intention is to apply FEC to UDP traffic that is passing through the VPN overlay, while allowing all other traffic to pass through without FEC.
