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. 2. Fortigate Troubleshoot Commands. Whenever an event occurs that may affect primary unit selection, Works like charm. In FortiGate HA one device will act as a primary device (also called Active FortiGate). Override is enabled so that cluster operation is more dynamic. Connected monitored ports > System uptime > Priority > FortiGate Serial number B. Diag. (not necessarily in this order, see the HA chapter in the Handbook). FGT-A fails and FGT-B becomes the new primary unit. HA override just cannot override the number of monitored ports. Main thing is, the cluster is working, and there are as few failovers / interruptions as possible. Disconnect power to the backup unit. -10.0.1.10 is the IP address for *.cdn.mozilla.net. Disabling override is recommended unless its important that the same FortiGate remains the primary FortiGate. The cluster recognizes that the configurations of FGT-A and FGT-B are not the same. 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. 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. Select your country below to see the regional support number, alternatively you may call our global support numbers: USA +1 408 542 7780.

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> Click the Maintenance tab. It's not statefull and just decide based on the current conditions. If you keep override enabled, the same FortiGate always becomes the primary FortiGate. After you have saved the configuration, cluster members begin to send heartbeat traffic to each other. HA links and synchronises two or more devices. Members with the same Group ID join the cluster. On the FortiGate creating a single aggregate interface . Created on 08-08-2018 250 is the highest. 05:23 AM. This template set is designed for A/P HA in Azure. In conclusion, it is straightforward to prepare and manage a redundant internet connection using fortinet firewalls. 02:29 AM. When both units are operating, FGT-A always becomes the primary unit because FGT-A has the highest device priority. Other times when we follow the same proccess, the secondary continue being the master, but that occurs in few situations. Fortigate routing address override. With override enabled, the disruption is minor and shouldn't be noticed by most users. Frequent negotiations may cause frequent traffic interruptions.". Session failover Session failover means that a cluster maintains active network sessions after a device or link failover. To see how enabling override can cause minor traffic disruptions, with override enabled set up a continuous ping through the cluster. If you disable override it is more likely that the backup FortiGate could become the primary FortiGate. Go to System > Settings. My question was because ive read that if you have override disabled, the comeup of a device doesnt affect the cluster hierarchy. 09:30 AM.

It wouldn't reduce the chances for the election for random situations. Created on Tested with FOS v6.0.0. HA failover can be forced on an HA primary unit. Connected monitored ports > HA uptime > Priority > FortiGate Serial number C. Connected monitored ports > Priority > HA uptime > FortiGate Serial number 08:35 AM. Configuration changes can be lost if and when you reconnect the disconnected unit to the cluster. Then obviously the unit that has the highest priority would be elected if override is enabled. The configuration changes made to FGT-B have been lost. In FortiOS v2.80 FortiOS v3.0 MR2 and later override is disabled by default. Call us. Enable the HA Sync option. A. 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. For this reason we don't use HA override. Configuration changes made to an HA cluster can be lost if HA override is enabled. The main issue is when you restores the monitored interface on the primary unit, it triggers a master election. To enable session failover you must change the HA configuration to select Enable Session . You will most likely notice a brief disruption in the ping traffic. Below are some additional HA troubleshooting commands you can use. At least below HA handbook: https://docs.fortinet.com/uploaded/files/3997/fortigate-ha-56.pdf, "With override enabled, the primary unit with the highest device priority will always If that helped the people of the forum would be fantastic. CPU. C. It is used to enable monitored ports. dia debug application hasync -1 dia debug application hatalk -1 dia deb ena. Created on The above output will show you the process of the HA Heartbeat conversations as well as the synchronization of the configs. Where did you read that? 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. Note that this is only used for testing, troubleshooting, and demonstrations. Register and apply licenses to the primary FortiGate before configuring it for HA operation. 1. diag sniffer packet any ' host 8.8.8.8 ' 4. They send synchronization traffic through their data links.

HA (A-P) mode FortiGate pairs as switch controller Multiple FortiSwitches managed via hardware/software switch Multiple FortiSwitches in tiers via aggregate interface with. If using an existing vnet, it must already have 5 subnets. 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. Sniffer. For example, consider the following sequence: The cluster is now operating with the same configuration as FGT-A. Then disconnect power to the backup unit. 03-30-2016 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. B. Override is enabled by default for early FortiOS v3.0 maintenance releases. The only way to connect to the secondary box was using the following command: execute ha manage 0 %admin-account% There is another option named Reserved Management Interface . The other two PIPs are for Management access . 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. Setting on unit on HA override breaks this scheme; almost always this unit will become master. 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. Also, there is heartbeat feature that provide both sides to detect each other. 11:45 PM. 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.. 08:30 AM, 1.number of up monitored ports>2.uptime(more than 5 min diff by default)>3.priority>4.serial number, 1.number of up monitored ports>2.priority>3.uptime(more than 5 min diff by default)>4.serial number. It synchronizes device priority on all cluster members. The cluster renegotiates and FGT-A becomes the new primary unit. If uptime difference is within the margin (ha-uptime-diff-margin), the last factor for the master election is serial numbers. Any idea of that? You should make sure that the device priority of the disconnected unit is lower than the device priority of the current primary unit and you should also make sure that override is disabled for the disconnected unit. With override enabled; however, the cluster may negotiate more often to keep the same FortiGate as the primary FortiGate, potentially increasing traffic disruptions. Session. Log into the GUI. Before you begin: You must have read-write permission for system settings. 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 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. Click on the System Information dashboard widget and select Configure settings in System > Settings. In FortiOS v2.80 you can also enable or disable Override Master from the web-based manager. Otherwise, when the disconnected unit joins the cluster, the cluster will renegotiate and the disconnected unit may become the primary unit. I have found out that the fact is the ha-uptime-margin so if you have override disabled, what is recommended by forti, the devices will compare the time they have been in the cluster unit, there are a few situations in which this time is set to 0 and starts again. Override is enabled, this will fail back the the primary firewall when it becomes available. # config system ha set group-name "HA_cluster" set mode a-p The configuration changes are made to FGT-B because FGT-B is operating as the primary unit. My settings for HA, override enabled : config system ha set route-ttl 180 set route-wait 0 set route-hold 10 set override-wait-time 180 BGP graceful globally enabled + for neighbors as well , BGP timers 10/30 , other timers are default. 08-24-2018 03:38 AM, Created on 07-12-2006 Scroll to the Upgrade section. 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. 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. When the checksums are identical, disable override on the primary FortiGate by entering the following command: FGCP clusters dynamically respond to network conditions. Physically link the FortiWeb appliances that will be members of the HA cluster. vanguard gmc sherman Fiction Writing-FortiGate allowed the traffic to pass. Disabling override (recommended) When the checksums are identical, disable override on the primary FortiGate by entering the following command: config system ha set override disable end FGCP clusters dynamically respond to network conditions. We often (than we want to) need to break HA when troubleshooting on a slave unit at the moment. If that helped the people of the forum would be fantastic, Created on The unit will stay in a failover state regardless of the conditions. Created on So its impossible to mantain the master until a manual action, although the comeup of the device with more priority? High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. 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. Not applicable .more .more. 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. Connecting the cluster Connect the HA cluster as shown in the initial diagram above. The only way to remove the failover status is by manually turning it off. Note: wait-time is enabled and set to 10 seconds to avoid any 'flap / stutter' that may cause disconnections when executing the override. Copyright 2022 Fortinet, Inc. All Rights Reserved.
