FortiGate HA Overview - FirewallShop.com. EN. What is the primary FortiGate election process when the HA override setting is disabled? If this happens, the configuration of the disconnected unit is synchronized to all other cluster units and any configuration changes made since the unit was disconnected are lost. 03-30-2016 FGT-A fails and FGT-B becomes the new primary unit. Then disconnect power to the backup unit. Created on There are many combinations of these commands but I mentioned only which I use and which can save your time of troubleshoot. The cluster recognizes that the configurations of FGT-A and FGT-B are not the same. Click to upload the firmware and start the upgrade process. For example, you might want to keep all device priorities at the default setting and just raise the device priority of the primary unit before making configuration changes. If override is enabled and you make configuration changes to a cluster these changes can be lost. When you configure a FortiGate in HA, normally, there is no way connect to the second box unless you ssh to the master and then connect via it to the secondary. Block EXE files from leaving to our network via FTP (filter3). Complete the configuration as described in Table 162. Enable the HA Sync option. Override is enabled, this will fail back the the primary firewall when it becomes available. 250 is the highest. Enter this CLI command to set the HA mode to active-passive; set a group ID, group name and password; increase the device priority to a higher value (for example, 250); and enable override. If uptime difference is within the margin (ha-uptime-diff-margin), the last factor for the master election is serial numbers. the anomaly begin when you try to come up the interface of the device which has more priority than the other one, and the device that has more priority becomes the master of the cluster and as Ive read the secondary firewall should mantain its condition as master. 02:29 AM. Otherwise, when the disconnected unit joins the cluster, the cluster will renegotiate and the disconnected unit may become the primary unit. Fortigate Troubleshoot Commands.

(not necessarily in this order, see the HA chapter in the Handbook). We recommend disabling override unless its important that the same FortiGate remains the primary FortiGate To see how enabling override can cause minor traffic disruptions, enable override and then set up a continuous ping through the cluster. The configuration of FGT-A is synchronized to FGT-B. HA override just cannot override the number of monitored ports. Primary unit selection with override enabled This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the user to set and modify system feature and ha category. I used to like the idea that "FGT1" will always be the master. Syntax config system ha set arps <integer> set arps-interval <integer> set datadev <datasource> set group-id <integer> set group-name <string> set hb-interval <integer> set hb-lost-threshold <integer> Register and apply licenses to the primary FortiGate before configuring it for HA operation. Created on The only way to remove the failover status is by manually turning it off. Session. Enter a new Host Name for this FortiGate. CPU. They send synchronization traffic through their data links. 12:43 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.. Sniffer. I always prefer to use verbose 4. as it gives me the detail from which interface packet has came in and out. Frequent negotiations may cause frequent traffic interruptions.". The main issue is when you restores the monitored interface on the primary unit, it triggers a master election. A. 11:45 PM. The cluster will suffer from more failovers than necessary in case the primary unit fails (in a HA sense) and comes back up. set mode a-p. set group-id 100. set group . Members with the same Group ID join the cluster. set direction any <- Inspect both . Connecting the cluster Connect the HA cluster as shown in the initial diagram above. The cluster is more likely to react immediately to an HA configuration change or other factor that could potentially lead to the cluster selecting a new primary unit. In the CLI example below, we want to file filter the following using Web filter profile: Block PDFs from entering our leaving our network (filter1). HA. As management is completely transparent I nowadays don't care anymore which unit has which role. FortiGate HA does not support session failover by default. 08-08-2018 So its impossible to mantain the master until a manual action, although the comeup of the device with more priority? Traffic matches the application profile on firewall policy ID 1. . vanguard gmc sherman Fiction Writing-FortiGate allowed the traffic to pass. When both units are operating, FGT-A always becomes the primary unit because FGT-A has the highest device priority. You will most likely notice a brief disruption in the ping traffic. -Traffic originated from 13.32.69.150. When override is enabled, you can prevent configuration changes from being lost by doing the following: A similar scenario to the above may occur when you use the Disconnect from Cluster option from the web-based manager or the execute ha disconnect command from the CLI to disconnect a cluster unit from a cluster. It synchronizes device priority on all cluster members. Below are some additional HA troubleshooting commands you can use. Go to System > Settings. A. Configuring the HA override will reboot the FortiGate device. Use this command to configure high availabilty (HA) settings. High availability in transparent mode Virtual clustering MAC address assignment Best practices VoIP Solutions: SIP Inside FortiOS: Voice over IP (VoIP) protection .

Disabling override is recommended unless its important that the same FortiGate remains the primary FortiGate. To enable override, log into the primary FortiGate CLI and enter this command: config system ha set override enable end Also, there is heartbeat feature that provide both sides to detect each other. Locate the System Information Dashboard widget. The cluster renegotiates and FGT-A becomes the new primary unit. 12:00 AM. After you have saved the configuration, cluster members begin to send heartbeat traffic to each other. To see how enabling override can cause minor traffic disruptions, with override enabled set up a continuous ping through the cluster. Other times when we follow the same proccess, the secondary continue being the master, but that occurs in few situations. This tells you the configuration is in sync. In conclusion, it is straightforward to prepare and manage a redundant internet connection using fortinet firewalls. Log into the GUI. the cluster negotiates.".

The unit will stay in a failover state regardless of the conditions. Monitor firewall health and auto-detect issues like misconfigurations or expired licenses before they affect network operations. To update the firmware for an HA cluster: Log into the web UI of the primary node as the admin administrator. This article explains the override enable wait timer option to address issue when HA override option is enabled on Active-Passive deployment, during HA fall back the former master unit will reclaim back the master role and will cause network interruption. On the FortiGate creating a single aggregate interface . 08-24-2018 Before adding the third FortiGate to the cluster, enable override on the primary FortiGate. Note: wait-time is enabled and set to 10 seconds to avoid any 'flap / stutter' that may cause disconnections when executing the override. If using an existing vnet, it must already have 5 subnets. Override is enabled by default for early FortiOS v3.0 maintenance releases. With override enabled; however, the cluster may negotiate more often to keep the same FortiGate as the primary FortiGate, potentially increasing traffic disruptions. In FortiGate HA one device will act as a primary device (also called Active FortiGate). Whenever an event occurs that may affect primary unit selection, These configuration changes are not synchronized to FGT-A because FGT-A is not operating. Fortigate High Availability Active / Passive GUI Setup 9,037 views Jan 21, 2021 How to setup high availability on FortiGate firewalls for Active / Passive deployment. Make sure the device priority of the primary unit is set higher than the device priorities of all other cluster units before making configuration changes. Make sure you are not using BFD with BGP! Fortinet Community Knowledge Base FortiGate Configuration changes lost when HA override enable. You can also enter this CLI command: config system global set hostname Backup_FortiGate end Duplicate the primary unit's HA settings, except make sure to set the backup device's priority to a lower value and do not enable override. The override is to flip the order 2 and 3. If you disable override it is more likely that the backup FortiGate could become the primary FortiGate. The configuration changes made to FGT-B have been lost. Verify that all cluster units are operating before making configuration changes (from the web-based manager go to. D. You must configure override settings manually and separately for each cluster member. become the primary unit. 08-08-2018 Try the same thing with override disabled and you shouldn't see this traffic disruption. Select your country below to see the regional support number, alternatively you may call our global support numbers: USA +1 408 542 7780. When override is enabled the cluster may renegotiate and potentially select a new primary unit (master) every time a cluster unit leaves or joins a cluster, every time a cluster unit changes status within a cluster, and every time the HA configuration of a cluster unit changes. You will likely notice a brief disruption in the ping traffic. Click Browse to locate and select the file. Tested with FOS v6.0.0. With override enabled, the disruption is minor and shouldn't be noticed by most users. set override enable << ensure override is enable set override-wait-time 120 << override-wait-time set priority 200 config secondary-vcluster set override enable << ensure override is enable set priority 100 set monitor "port9" "port10" set vdom "WANFW" end end Slave HA setting. 08-09-2018 Created on For this reason we don't use HA override.

B. 01:02 AM, If port monitoring enabled AND if an interface that was down comes up on a subordinary unit AND if this unit has more interfaces up (than the current primry)this situation is a by design behaviour (its normal), --------------------------------------------, Created on If you keep override enabled, the same FortiGate always becomes the primary FortiGate. Note that this is only used for testing, troubleshooting, and demonstrations. When the checksums are identical, disable override on the primary FortiGate by entering the following command: FGCP clusters dynamically respond to network conditions. In most cases this step would not be necessary but it is a best practice because enabling override makes sure the configuration of the primary FortiGate is not overwritten by the configuration of the new backup FortiGate. 05:23 AM. override is disabled if you think that the problem is in this fact. Physically link the FortiWeb appliances that will be members of the HA cluster. Configuration changes lost when HA override enable Configuration changes lost when HA override enabled, Override and disconnecting a unit from a cluster. A cluster of two FortiGate units is operating with the following configuration: FGT-A: Primary unit with HA device priority 200 and with, FGT-B: Subordinate unit with HA device priority 100 and. Created on For an example, see Active-pastive HA topology and failover IP address transfer to the new active appliance or Active-active HA topology and failover in reverse proxy mode.. 3. Created on Created on Click the Maintenance tab. We have two FortiGates 201E, and we have configured a cluster to get high availability, all the interfaces which are giving services are por monitoring interfaces, so if any of them break down, the master of the cluster change. 05:50 AM. Save the configuration. Before you begin: You must have read-write permission for system settings. My question was because ive read that if you have override disabled, the comeup of a device doesnt affect the cluster hierarchy. Active device synchronises its configuration with another device in the group. I think that is better to mantain the master in this situation in order to not stop the services which are being supported by the firewall.
