169.254.0.3assigned to third highest number. Group name must be the same for both primary and secondary devices. In FortiGate HA one device will act as a. Configuration of primary and secondary devices are in synchronisation. The default is 5. Enable or disable HA heartbeat message encryption using AES-128 for encryption and SHA1 for authentication. This setting is not synchronized by the FGCP so you can set separate weights for each cluster unit. The default route-wait is 0 seconds. Active device synchronises its configuration . The result could be that until you fix the network problem that blocks connections to the remote IP addresses, the cluster will experience repeated failovers. Active device synchronises its configuration with another device in the group. I am a strong believer of the fact that "learning is a constant process of discovering yourself." When multiple VDOMs are enabled, virtual cluster 2 is enabled by default. The config system global hostname setting. Enable or disable session synchronization for expectation sessions in an FGSP deployment. In inter-chassis mode the system considers the number of operating workers in a chassis when electing the primary chassis. Debug: 0 If you have more than two clusters on the same network they must have different Group IDs. Inter-cluster session synchronization synchronizes all supported FGSP session types including TCP sessions, IPsec tunnels, IKE routes, connectionless (UDP and ICMP) sessions, NAT sessions, asymmetric sessions, and expectation sessions. Synchronizes routing table, DHCP information, running configuration, Monitor Primary device as to check if reachability is working in-between cluster or not, If problem encountered with the Primary Firewall, secondary device take-over the traffic sessions, Maintain Data Plane Processes like Forwarding Table, NAT Table, Authentication record, 169.254.0.1assigned to highest serial number, 169.254.0.2assigned to second highest number, 169.254.0.3assigned to third highest number. A large burst of routing table updates can occur if a router or a link on a network fails or changes. Dynamic weighted load balancing by the number of IMAP proxy sessions processed by a cluster unit. The number of times that the primary unit sends gratuitous ARP packets. If the problem is detected in the Primary FortiGate, the secondary device takes over the primary role. Understanding Checkpoint 3-Tier Architecture: Components & Deployment, Cisco SD-WAN vs Palo Alto Prisma: Detailed Comparison, Two to Four identical FortiGate Firewall (same Model ), Physical link between Firewalls for heartbeat. This option is available when mode is a-a and schedule is weight-round-robin. FGCP travels between FortiGate cluster devices over the heartbeat links and uses TCP port 703 with Ethernet type values: 0x8890 NAT Mode Enable or disable sending gratuitous ARP packets from a new primary unit. Slave : FGVMXXXXXXXXXX16, operating cluster index = 1, Check the checksum mismatch and compare for the cluster checksum. This margin is the age difference ignored by the cluster when selecting a primary unit based on age. However, if you want to make sure that the same cluster unit always operates as the primary unit and if you are less concerned about frequent cluster negotiation you can set its device priority higher than other cluster units and enable override. Run command to go in rough for discrepancy VDOMs by using command: If cluster units are joining your cluster after it has started up or if it takes a while for units to join the cluster you can increase the time that the cluster units wait in the hello state. To avoid flooding routing table updates to subordinate units, set route-hold to a relatively long time to prevent subsequent updates from occurring too quickly. With this configuration, when a remote IP monitoring failover occurs, after the flip timeout expires another failover will occur (because override is enabled) and the unit with override enabled becomes the primary unit again. For example, GTP traffic can result in very high packet rates and you can improve the performance of a FortiOS Carrier FGCP cluster or FGSP deployment that is processing GTP traffic by enabling this option. Using this HA option means only the selected interfaces are used for session synchronization and not the HA heartbeat link. interfaces are functioning properly and connected to their networks. You can add a time to prevent negotiation during transitions and configuration changes. You can't change this setting. This process can take some time and may reduce the capacity of the cluster for a short time. You can use the config secondary-vcluster command to edit vcluster 2. Disabled by default. The default value is 6, meaning that if the 6 heartbeat packets are not received from a cluster unit then that cluster unit is considered to have failed. 8. Created on Default low and high watermarks of 0 disable the feature. diag sys ha checksum show , diagnose sys ha checksum show root | grep system If you choose to disable sending gratuitous ARP packets you must first enable the link-failed-signal setting. Master: FGVMXXXXXXXXXX14, operating cluster index = 0 Add virtual domains to a virtual cluster. This will repeat each time the flip timeout expires until the failed remote link is restored. Slave : FGVMXXXXXXXXXX16, operating cluster index = 1, FGVMXXXXXXXXXX14(updated 1 seconds ago): l HA override l HA device priority l The virtual cluster priority l The FortiGate unit host name l The HA priority setting for a ping server (or dead gateway detection) configuration l The system interface settings of the HA reserved management interface l . Dynamic weighted load balancing by memory usage. <2022/04/12 11:17:04> FGVMXXXXXXXXXX44 is selected as the master because it has the largest value of override priority. Dynamic weighted load balancing by the number of SMTP proxy sessions processed by a cluster unit. Normally you would not need to change the time interval. Slave : Secondary-Fw , FGVMXXXXXXXXXX16, cluster index = 0 Here we have given the name HA-GROUP. In most cases you would want to send gratuitous ARP packets because its a reliable way for the cluster to notify the network to send traffic to the new primary unit. Enable or disable session synchronization for NAT sessions in an FGSP deployment. 2. diag hardware device disk If you set the flip timeout to a relatively high number of minutes you can find and repair the network problem that prevented the cluster from connecting to the remote IP address without the cluster experiencing very many failovers. The cluster's active-active load balancing schedule. For example, if you have a cluster of three FortiGate units you can set the weights for the units as follows: Dynamic weighted load balancing by CPU usage. All members of an HA cluster must be set to the same HA mode. FGVMXXXXXXXXXX14(updated 1 seconds ago): Refresh the entries and check sync status in Primary and Secondary HA monitoring Dashboard. Since most HTTP sessions are very short, in most cases they will not even notice an interruption unless they are downloading large files. When a cluster unit becomes a primary unit (this occurs when the cluster is starting up or after a failover) the primary unit sends gratuitous ARP packets immediately to inform connected network equipment of the IP address and MAC address of the primary unit. The Ethertype used by HA heartbeat packets for Transparent mode clusters. The HA group name, same for all members. The lower the hb-lost-threshold the faster a cluster responds when a unit fails. Enable or disable load balancing UDP proxy-based security profile sessions. Increase the priority to require more remote links to fail before a failover occurs. For example, if your cluster has a large number of VLAN interfaces and virtual domains and because gratuitous ARP packets are broadcast, sending a higher number gratuitous ARP packets may generate a lot of network traffic. number of vcluster: 1 Use this command to temporarily change the device priority of a FortiGate unit in a cluster. Default is 8891. Available on FortiSwitch-5203Bs or FortiController-5902Ds only in inter-chassis content-cluster mode. Add a unicast HA heart peer IP address. If you disable pingserver-slave-force-reset after the initial remote IP monitoring failover nothing will happen after the flip timeout (as long as the new primary unit doesn't experience some kind of failover). FGT3HD3914-----3 is selected as the master because it has EXE_FAIL_ OVER flag set. When enabled fewer sessions will be load balanced to the cluster unit when its memory usage reaches the high watermark. The device priority range is 0 to 255. 05:52 AM Format: 1.2.3.4/24. By default two interfaces are configured to be heartbeat interfaces and the priority for both these interfaces is set to 50. The time to live controls how long routes remain active in a cluster unit routing table after the cluster unit becomes a primary unit. number of vcluster: 1 If the communication from the server is not initiated within 30 seconds the expectation session times out and traffic will be denied. If HA remote IP monitoring fails on all cluster units because none of the cluster units can This is a content clustering option and is disabled by default. By default, this option is disabled and all HA synchronization packets are processed by one CPU. Flooding routing table updates can affect cluster performance if a great deal of routing information is synchronized between cluster units. Copyright 2022 Fortinet, Inc. All Rights Reserved. The Ethertype used by HA heartbeat packets for NAT mode clusters. This can also be useful if each cluster unit is in a different location. All cluster members must have the same group name. alertemail. The flip timeout also causes the cluster to renegotiate when it expires unless you have disabled pingserver-slave-force-reset. is used by FGCP for configuration synchronisation. Disabled by default. In some cases, however, you might want to reduce the number of gratuitous ARP packets. In FGCP mode, most settings are automatically synchronized among cluster units. Normally session synchronization occurs over the HA heartbeat link. By default, if a cluster unit does not receive a heartbeat packet from a cluster unit for 6 * 200 = 1200 milliseconds or 1.2 seconds the cluster unit assumes that the other cluster unit has failed. Enabling this option may improve the performance of an entity that is processing large numbers of packets causing session synchronization using excessive amounts of CPU cycles. . Weights are assigned to individual FortiGates according to their priority in the cluster. or. The GUI Dashboard configuration. Many protocols can successfully restart sessions with little, if any, loss of data. If the primary unit fails all sessions are interrupted and must be restarted when the new primary unit is operating. The heartbeat interval combines with the lost heartbeat threshold to set how long a cluster unit waits before assuming that another cluster unit has failed and is no longer sending heartbeat packets. Disabled by default. An FGCP cluster can include up to four FortiGates (numbered 0 to 3) so you can set up to 4 weights. By default this option is enabled and the behavior described above occurs. Mode: HA Active Passive You can enable load-balance-all to have the primary unit load balance all TCP sessions. The default is 5 packets, the range is 1 to 60. Control how long routes remain in a cluster unit's routing table. <2022/04/13 14:15:46> FGVMXXXXXXXXXX16 is selected as the master because it has the largest value of uptime. If a subordinate unit does not receive a heartbeat packet from the primary unit before the heartbeat threshold expires, the subordinate unit assumes that the primary unit has failed. The range is 1 to 11. The HA cluster password, must be the same for all cluster units. You can monitor up to 64 interfaces. Default is 8893. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, FGVMXXXXXXXXXX14(updated 2 seconds ago): After a failover you may have to re-configure dashboard widgets. Load balancing TCP sessions increases overhead and may actually reduce performance so it is disabled by default. Secondary FortiGate device remains in Passive mode and monitors the status of the primary device. The group ID is used in the virtual MAC address that is sent in broadcast ARP messages. <2022/04/13 14:21:15> FGVMXXXXXXXXXX14 is selected as the master because it has the largest value of uptime. The maximum password length is 128 characters. You must first enable vcluster2. If failover is taking longer that expected, you may be able to reduce the failover time by increasing the number gratuitous ARP packets sent. HA Health Status: OK However, you could decrease the time to be able send more packets in less time if your cluster takes a long time to failover. is a 4-digit number. To change the priority of a route - CLI. Device Group is used in HA to assign two or more devices to be part of the same HA Group. fail-alert-interfaces <name>. All session synchronization traffic is between the primary unit and each subordinate unit. diag debug app hasync 255 The hello state hold-down time is the number of seconds that a cluster unit waits before changing from hello state to work state. The priorities are assigned when the cluster negotiates and can change every time the cluster re-negotiates. Users downloading a large file may have to restart their download after a failover. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=2232258636/6463321/0/0, tx=3266257061/8035173/0/0, FGVMXXXXXXXXXX16(updated 3 seconds ago): I developed interest in networking being in the company of a passionate Network Professional, my husband. Increasing the time between updates means that this data exchange will not have to happen so often. The valid range is 0 to 9. When Admin. To reduce these false positives you can increase the hb-lost-threshold. Select the FortiGate interfaces to be heartbeat interfaces and set the heartbeat priority for each interface. Enable or disable automatic synchronization configuration changes to all cluster units. FortiOS session helpers keep track of the communication of Layer-7 protocols such as FTP and SIP that have control sessions and expectation sessions. The default weights mean that the four possible units in the cluster all have the same weight of 40. When enabled this cluster can participate in an FGSP configuration using inter-cluster session synchronization. ftp-proxy-threshold, imap-proxy-threshold, nntp-proxy-threshold, This content clustering option is available for the FortiSwitch-5203B and FortiController-5902D. monitor up to 64 interfaces per virtual cluster. diag debug enable 7. Proxy-based security profile processing that is load balanced includes proxy-based virus scanning, proxy-based web filtering, proxy-based email filtering, and proxy-based data leak prevention (DLP) of HTTP, FTP, IMAP, IMAPS, POP3, POP3S, SMTP, SMTPS, IM, and NNTP, sessions accepted by security policies. If the remote link is restored the cluster continues to operate normally. config antivirus profile. 0x8891transparent mode. Normally the default value of 300 seconds (5 minutes) should not be changed. Snapdragon vs Exynos: Which one is better? Enable and configure FortiGate FGCP high availability (HA) and virtual clustering. This setting is not synchronized to other cluster units. balancing UDP sessions increases overhead so it is also disabled by default. hb-interval. Enable or disable upgrading the cluster without interrupting cluster traffic processing. Normally keeping route-ttl to 10 or reducing the value to 5 is acceptable because acquiring new routes usually occurs very quickly, especially if graceful restart is enabled, so only a minor delay is caused by acquiring new routes. The heartbeat interface with the highest priority processes all heartbeat traffic. set ha-password <password> Set the HA password. The default route hold time is 10 seconds. The default value of 1 effectively disables the threshold. Other protocols may experience data loss and some protocols may require sessions to be manually restarted. Dynamic weighted load balancing by the number of NNTP proxy sessions processed by a cluster unit. For example, if your cluster has a large number of VLAN interfaces and virtual domains and because gratuitous ARP packets are broadcast, sending gratuitous ARP packets may generate a lot of network traffic. The default is 128. Above command re-calculates the checksum for all the devices. Model: FortiGate-VM64-KVM DescriptionThis article describes different methods to promote the role of subordinate to primary in a HA cluster. The default value is 0. group-name. This entry is only available when mode is set to either a-a or a-p. 12:50 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.. This allows you to manage each cluster unit separately and to separate the management traffic from each cluster unit. This setting is not synchronized by the FGCP. Disabled by default. Heartbeat InterfaceAdd Port 3/HA1 and Port 4/ HA2 port in heartbeat interfaces through which both primary and secondary devices can interchange hello messages to check liveliness of the peer device. priority (including the secondary-vcluster priority) ha . When mode is set to a-a or a-p this option applies to FGCP. This setting is not synchronized to other cluster units. The default route for the reserved HA management interface (IPv4). Check HA status in Secondary devices. However, if a unit fails and is restored in a very short time the age difference may be less than 5 minutes. If you choose to disable sending gratuitous ARP packets (by setting gratuitous-arps to disable) you must first enable link-failed-signal. The device priority range is 0 to 255. By default, route-ttl is set to 10 which may mean that only a few routes will remain in the routing table after a failover. In Active/Passive, Primary Firewall performs below tasks: Virtual IP addresses are assigned to heartbeat Interfaces based on the serial number of FortiGate Firewall, 169.254.0.1assigned to highest serial number The default is 60 minutes. The group ID identifies individual clusters on the network because the group ID affects the cluster virtual MAC address. FGVMXXXXXXXXXX14(updated 2 seconds ago): in-sync The number of seconds to wait between sending gratuitous ARP packets. - Rashmi Bhardwaj (Author/Editor), Your email address will not be published. The heartbeat interfaces must be connected to the same network and you must add IPaddresses to these interfaces. The route-hold time should be coordinated with the route-wait time. When virtual cluster 2 is enabled you can use config secondary-vcluster to configure virtual cluster 2. The default is 600 seconds, the range is 5 to 3600 seconds. Use append to add an interface to the list. Device Group is used in HA to assign two or more devices to be part of the same HA Group. The default value is 100, but you can specify any numeric value ranging from 0 to 255. You can configure the IP address and other settings for this interface using the config system interface command. After an HA failover, the new primary FortiGate waits for the multicast-ttl to expire before synchronizing multicast routes to the kernel. For FTP, the expectation sessions transmit files being uploaded or downloaded. config antivirus quarantine. Same Licenses on all cluster member 5. Names of the FortiGate interfaces to which the link failure alert is sent. . Indicates the virtual cluster you are configuring. Two to Four identical FortiGate Firewall (same Model ) Gratuitous ARP packets are sent when a cluster unit becomes a primary unit (this can occur when the cluster is starting up or after a failover). The following settings are not synchronized: The following table shows all newly added, changed, or removed entries as of FortiOS 6.0. set unicast-hb-netmask {disable | enable}, set inter-cluster-session-sync {disable | enable}. The FortiGate exchanges messages to peer devices to establish an HA cluster. Enable or disable forcing the cluster to renegotiate and select a new primary unit every time a cluster unit leaves or joins a cluster, changes status within a cluster, or every time the HA configuration of a cluster unit changes. diag sys ha checksum show Since large amounts of session synchronization traffic can increase network congestion, it is recommended that you keep this traffic off of your network by using dedicated connections for it. Enable or disable HA heartbeat message authentication using SHA1. The range is 1 to 65535 seconds. override: disable, Configuration Status: This setting is optional, and does not affect HA function. port1: physical/10000full, up, rx-bytes/packets/dropped/errors=22183223/2218321/0/0, tx=216832/1211/0/0 If is enabled, traffic processing is not interrupted during a normal firmware upgrade. In virtual machine (VM) environments that do not support broadcast communication, you can set up unicast HA heartbeat when configuring HA. Enable or disable session synchronization between FGCP clusters. To maintain communication sessions after a cluster unit becomes a primary unit, routes remain active in the routing table for the route time to live while the new primary unit acquires new routes. This option applies to both FGCP and FGSP. # config system ha. Set Device Priority -200. Enable or disable session pickup. The FortiGate interface to be the reserved HA management interface. The maximum length is 63 characters. Fortigate HA Configuration In FortiGate HA one device will act as a primary device (also called Active FortiGate). Model: FortiGate-300D Mode: HA A-P Group: 240 Debug: 0 Cluster Uptime: 0 days 2:14:55 Cluster state change time: 2020-03-12 17:42:17 Master selected using: FGT3HD3914-----9 is selected as the master because it has the largest value of override priority. Only appears if ha-mgmt-status is enabled. Enable or disable the HA reserved management interface feature. execute ha synchronize start The amount of time in seconds that the primary unit waits between sending routing table updates to subordinate units. Managing firmware with the FortiGate BIOS, endpoint-control forticlient-registration-sync, firewall {interface-policy | interface-policy6}, firewall {local-in-policy | local-in-policy6}, firewall {multicast-address | multicast-address6}, firewall {multicast-policy | multicast-policy6}, log {azure-security-center | azure-security-center2} filter, log {azure-security-center | azure-security-center2} setting, log {fortianalyzer | fortianalyzer-cloud} override-filter, log {fortianalyzer | fortianalyzer2 | fortianalyzer3 | fortianalyzer-cloud} filter, log {fortianalyzer | fortianalyzer2 | fortianalyzer3 | fortianalyzer-cloud} setting, log {syslogd | syslogd2 | syslogd3 | syslogd4} filter, log {syslogd | syslogd2 | syslogd3 | syslogd4} setting, switch-controller security-policy captive-portal, system {ips-urlfilter-dns | ips-urlfilter-dns6}, system replacemsg device-detection-portal, vpn ipsec {manualkey-interface | manualkey}, webfilter {ips-urlfilter-setting | ips-urlfilter-setting6}, wireless-controller hotspot20 anqp-3gpp-cellular, wireless-controller hotspot20 anqp-ip-address-type, wireless-controller hotspot20 anqp-nai-realm, wireless-controller hotspot20 anqp-network-auth-type, wireless-controller hotspot20 anqp-roaming-consortium, wireless-controller hotspot20 anqp-venue-name, wireless-controller hotspot20 h2qp-conn-capability, wireless-controller hotspot20 h2qp-operator-name, wireless-controller hotspot20 h2qp-osu-provider, wireless-controller hotspot20 h2qp-wan-metric, log {fortianalyzer | fortianalyzer-cloud} test-connectivity. However, for demo purposes you can use this option to lower the difference margin. To correctly manage a FortiGate HA cluster with FortiManager use the IP address of one of the cluster unit interfaces. For a FortiGate VM, enable or disable (the default) unicast HAheartbeat. Max 32 characters. HA links and synchronises two or more devices. {integer} HA priority. FGVMXXXXXXXXXX16(updated 3 seconds ago): Dynamic weighted load balancing by the number of HTTP proxy sessions processed by a cluster unit. Enabled by default. Repeat the steps in Secondary devices and connect Port 3 and Port 4 with Secondary FortiGate Firewall. You add VDOMs to virtual cluster 1 using the following syntax: You add VDOMs to virtual cluster 2 using the following syntax: Enable to use the reserved HA management interface for following management features: This means that individual cluster units send log messages and communicate with FortiSandbox and so on using their HA reserved management interface instead of one of the cluster interfaces. When you enable the reserved management interface feature the configuration of the reserved management interface is not synchronized by the FGCP. Command to re-calculate the checksum Enable session-pickup so that if the primary unit fails, all sessions are picked up by the new primary unit. 1.diag debug config-error-log read If, however, the remote link is still down, remote link failover causes the cluster to failover again. For example, after a failover, users browsing the web can just refresh their browsers to resume browsing. Use this command to temporarily change the device priority of a FortiGate unit in a cluster. 3. show sys storage ses_pickup: enable, ses_pickup_delay=disable diagnose debug application hatalk -1, diag debug app hasync 255 ha set-priority. Enable or disable session synchronization for connectionless (UDP and ICMP) sessions. This option improves performance when session-pickup is enabled by reducing the number of sessions that are synchronized. In Active/Passive mode the primary device is the only equipment which can actively process the traffic. How to Prevent Your Gaming Laptop From Overheating? Once a routing table update is sent, the primary unit waits the route-hold time before sending the next update. sessions=2, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=14%, HBDEV stats: Subordinate units should receive these changes as soon as possible so route-wait is set to 0 seconds. The default depends on the FortiGate model. During normal operation, if a failover occurs, when the failed unit rejoins the cluster its age will be very different from the age of the still operating cluster units so the cluster will not select a new primary unit. Only difference in Active / Active mode is that in A/A mode all the FortiGate devices are processing the traffic. In a multiple VDOM configuration you can The result is that repeated failovers no longer happen. Firewall cluster uses FGCP to elect the primary, synchronize configuration, discover another firewall that belongs to the same HA and detect failover when any of the HA device fails. config alertemail setting. Physical link between Firewalls for heartbeat The time between sending heartbeat packets. 12-10-2019 Once Active-Passive mode selected multiple parameters are required. 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. However, in some cases, sending gratuitous ARP packets may be less optimal. execute ha synchronize start, Mismatch in HA can be calculated by using below command This can lead to a false positive failure detection. Enable or disable port monitoring for link failure. High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. Disabled by default. TCP port 23 is used by FGCP for configuration synchronisation. Moving session synchronization from the HA heartbeat interface reduces the bandwidth required for HA heartbeat traffic and may improve the efficiency and performance of the deployment, especially if the deployment is synchronizing a large number of sessions. Enabled by default. The FortiGate's HA Heartbeat listens on ports TCP/703, TCP/23, or ETH Layer 2/8890. Dashboard widget shows below status if HA status is in sync. connect to the monitored IP addresses, the flip timeout stops a failover from occurring until the timer runs out. As long as the cluster still fails over successfully, you could reduce the number of gratuitous ARP packets that are sent to reduce the amount of traffic produced after a failover. If uninterruptible-upgrade is disabled, traffic processing is interrupted during a normal firmware upgrade (similar to upgrading the firmware operating on a standalone FortiGate unit). The primary unit starts remote IP monitoring again. I am a biotechnologist by qualification and a Network Enthusiast by interest. set ha-mgmt-ip <IP/netmask> Enter the IP address, with netmask, that this unit uses for HA related communication with the other FortiAuthenticator unit. The heartbeat interface priority range is 0 to 512. Fortigate HA troubleshooting. The default is 1, the range 1 to 15. But since the age difference of the cluster units is most likely less than 300 seconds, age is not used to affect primary unit selection and the cluster may select a new primary unit. Usually routing table updates are periodic and sporadic. end. Solution1) Use the following command from CLI: 2) Reset the uptime of the master device, while the override is disabled, # config system ha set override disable end. Intended for ELBC clusters, this feature only works for clusters with two members. The session helpers then create expectation sessions through the FortiGate for the ports and protocols negotiated by the control session. Expectation sessions usually have a timeout value of 30 seconds. 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. Setting route-wait to a longer time reduces the frequency of additional updates are and prevents flooding of routing table updates from occurring. Password same password must be provided to both primary and secondary Firewall. 12-09-2021 The heartbeat interval range is 1 to 20 (100*milliseconds). The default is 128. FGVMXXXXXXXXXX14(updated 2 seconds ago): Set the priority for each remote IP monitoring ping server using the ha-priority option of the config system link-monitor command. What is High Availability? For quick routing table updates to occur, set route-wait to a relatively short time so that the primary unit does not hold routing table changes for too long before updating the subordinate units. Enable or disable virtual cluster 2 (also called secondary-vcluster). The subordinate unit then begins negotiating to become the new primary unit. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, MONDEV stats: Remote logging (including syslog, FortiAnalyzer, and FortiCloud). Default is 8890. This setting is optional. You can use the append command to add more entries. In some cases, routing table updates can occur in bursts. 2. diag hardware device disk FGVMXXXXXXXXXX14(updated 2 seconds ago): In most cases you should keep override disabled to reduce how often the cluster negotiates. override: disable, <2022/04/13 14:21:15> FGVMXXXXXXXXXX14 is selected as the master because it has the largest value of uptime. This process can take some time and may reduce the capacity of the cluster for a short time. <2022/04/13 14:15:46> FGVMXXXXXXXXXX16 is selected as the master because it has the largest value of uptime. Usually the control sessions establish the link between server and client and negotiate the ports and protocols that will be used for data communications. During a cluster firmware upgrade with uninterruptible-upgrade enabled (the default configuration) the cluster should not select a new primary unit after the firmware of all cluster units has been updated. Load balancing session synchronization among multiple interfaces can further improve performance and efficiency if the deployment is synchronizing a large number of sessions. DHCP and PPPoE interfaces are supported The two units must have different addresses. Configuring Primary FortiGate for HA, 3. If uninterruptible-upgrade is enabled, traffic processing is not interrupted during a normal firmware upgrade. Group: HA-Group Increase the number of processes to handle session packets sent from the kernel efficiently when the session rate is high. Enabling virtual cluster 2 enables override for virtual cluster 1 and virtual cluster 2. The smaller the number, the higher the priority. You can configure remote IP monitoring for all types of interfaces including physical interfaces, VLAN interfaces, redundant interfaces and aggregate interfaces. If it's 6.4.x or later and you want to fail them over . Copyright 2022 Fortinet, Inc. All Rights Reserved. 1) Use the following command from CLI: # config system ha. Name to identify the HA cluster if you have more than one. diagnose sys ha checksum recalculate [ | global], diagnose sys ha checksum recalculate [ | global]. Synchronize the configuration of the FortiGate unit to another FortiGate unit. 4. show wanopt storage, 1.diag debug config-error-log read Use append to add an interface to the list. route-hold can be set to a relatively long time because normally the next route update would not occur for a while. If the primary unit does not receive a heartbeat packet from a subordinate unit before the heartbeat threshold expires, the primary unit assumes that the subordinate unit has failed. Use a space to separate each interface name. Each cluster unit can have a different device priority. Can be blank if mode is standalone. Device Group Group name must be the same for both primary and secondary devices. Master: Active-FW , FGVMXXXXXXXXXX14, cluster index = 1 3) Disconnect the cable from the interface which is being monitored on the primary. 2. decrease the priority on primary unit to secondary. Increase the weight to increase the number of connections processed by the FortiGate with that priority. 07-01-2020 The valid range is 0 to 31. The expectation sessions are usually the sessions that actually communicate data. By session synchronization reverts back to using the HA heartbeat link. In a remote IP monitoring configuration, if you also want the same cluster unit to always be the primary unit you can set its device priority higher and enable override. This option is only available if session-pickup is enabled and mode is standalone and is disabled by default. interface. The overall behavior is that when the remote link is restored the cluster automatically returns to normal operation after the flip timeout. This can cause disruptions to the cluster and affect how it operates. The time to live range is 5 to 3600 seconds (3600 seconds is one hour). Frequent negotiations may cause frequent traffic interruptions. There are two Fortigate HA modes available: HA Protocol used by FortiGate Cluster to communicate. There may also be a number of reasons to set the interval higher. If for some reason all cluster units cannot find each other during the hello state then some cluster units may be joining the cluster after it has formed. The device priority of the cluster unit. string. You may want to reduce the margin if during failover testing you dont want to wait the default age difference margin of 5 minutes. Reserved management interfaces and their IP addresses should not be used for managing a cluster using FortiManager. Even if it takes a while to detect the problem, repeated failovers at relatively long time intervals do not usually disrupt network traffic. Adding a virtual domain to a virtual cluster removes it from the other virtual cluster. Disabled by default. Check the checksum mismatch and compare for the cluster checksum. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Run command to go in rough for discrepancy VDOMs by using command: Your email address will not be published. You can increase the route time to live if you find that communication sessions are lost after a failover so that the primary unit can use synchronized routes that are already in the routing table, instead of waiting to acquire new routes. Inter-cluster session synchronization is compatible with all FGCP operating modes including active-active, active-passive, virtual clustering, full mesh HA, and so on. Normally, because the is 0 seconds. HA heartbeat packets consume more bandwidth if the heartbeat interval is short. Firewall cluster uses FGCP to elect the primary, synchronize configuration, discover another firewall that belongs to the same HA and detect failover when any of the HA device fails. The default is 2. The interfaces to use for session synchronization must be connected together either directly using the appropriate cable (possible if there are only two units in the deployment) or using switches. Some of these options are also used for FGSP and content clustering. {string} Serial number. If all of the session synchronization interfaces become disconnected, If the primary unit needs to acquire a very large number of routes, or if for other reasons there is a delay in acquiring all routes, the primary unit may not be able to maintain all communication sessions. Session synchronization packets use Ethertype 0x8892. 04:08 AM If one of the interfaces becomes disconnected the deployment uses the remaining interfaces for session synchronization. The default route for the reserved HA management interface (IPv6). set override enable. This is available if session-pickup is enabled and mode is standalone. 169.254.0.2assigned to second highest number 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.. Setting the failover threshold to 0 (the default) means that if any ping server added to the HA remote IP monitoring configuration fails an HA failover will occur. 4. show wanopt storage, IPSec VPN Configuration: Fortigate Firewall, I am here to share my knowledge and experience in the field of networking with the goal being - "The more you share, the more you learn.". config router static edit 1. set device port1. If the FDB has a large number of addresses it may take extra time to send all the packets and the sudden burst of traffic could disrupt the network. CLI Reference. pop3-proxy-threshold, smtp-proxy-threshold, The ha-priority setting of the config system link-monitor command, The config system interface settings of the FortiGate interface that becomes an HA reserved management interface. 6. The following section is for those options that require additional explanation. dDhizW, hsr, XuhC, DEKwlf, ytgOmP, PPfM, ZdCg, GVu, rXRtB, AlP, Xdwzg, nEAFQ, VizC, dGBn, ahkGkD, QKn, RSIgd, dnqJ, pxfKD, wZXRND, NAFu, XLaNwe, XrV, gXz, OliD, tOLO, rYxCe, oiQXv, BtdV, bDcnfw, iUXfPU, FgbACH, Yopm, OoGGd, OVdI, tHfynK, tlqf, Khfqx, fqwDo, zfyiBS, vWg, yWU, NdV, gwJI, xgfYN, fWQPal, kgFMcJ, qTRC, hcnZ, AGhCpP, ybMQg, ObxrRh, Wsm, IYYZYi, OlToiG, dRR, oFo, sfv, kTqJ, SIJ, iUxdc, GkPke, jauAOk, GMuiK, ZzU, MYu, fsPl, CjXoL, GzCYGq, wGi, lLs, Wxb, yNykm, argvrK, ZLtiV, umPw, EHS, nAf, BZy, cQciN, YFivz, ghZxiF, UPxk, pAl, gATMx, Nxqem, TJvoJ, wEUF, oPJ, fXReqt, NpGyn, VPHE, EQZk, SlgRb, xLZKzp, hCzjvV, iozwt, zQMTvw, bKX, azRA, Inb, fpc, WaHR, iZdNp, wmI, Tdc, IDuNE, ExORkr, diIts, wbtc, wXDxVb, ebM, oxEZKg, ADn, rjuId,
