ses_pickup: enable, ses_pickup_delay=disable 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.". If you have more than two clusters on the same network they must have different Group IDs. Configure virtual cluster 2 using the following syntax. This option is available when mode is a-a and schedule is weight-round-robin. Once Active-Passive mode selected multiple parameters are required. Required fields are marked *, Copyright AAR Technosolutions | Made with in India, Heartbeat Interfaces and Virtual IP Interfaces, High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. Run command to go in rough for discrepancy VDOMs by using command: Your email address will not be published. High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. If, however, the remote link is still down, remote link failover causes the cluster to failover again. Default low and high watermarks of 0 disable the feature. Dynamic weighted load balancing by memory usage. To reduce these false positives you can increase the hb-lost-threshold. The number of processes used by the HA session sync daemon. The weight is set according to the priority of the unit in the cluster. FGVMXXXXXXXXXX14(updated 2 seconds ago): in-sync This allows you to manage each cluster unit separately and to separate the management traffic from each cluster unit. If you select more than one interface, session synchronization traffic is load balanced among the selected interfaces. 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. Enable or disable HA heartbeat message authentication using SHA1. Select the FortiGate interfaces to be heartbeat interfaces and set the heartbeat priority for each interface. Repeat the steps in Secondary devices and connect Port 3 and Port 4 with Secondary FortiGate Firewall. Names of the FortiGate interfaces to which the link failure alert is sent. After a failover you may have to re-configure dashboard widgets. 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. Run command to go in rough for discrepancy VDOMs by using command: 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. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. You may want to reduce the margin if during failover testing you dont want to wait the default age difference margin of 5 minutes. hb-interval. There may also be a number of reasons to set the interval higher. The device priority of the cluster unit. The maximum password length is 128 characters. Enable this option if the switch the cluster is connected to does not update its MAC forwarding tables after a failover caused by a link failure. Set Device Priority -200. Debug: 0 set override disable. Note: By default, uptime is more important than this setting unless Override is enabled. FGVMXXXXXXXXXX16(updated 3 seconds ago): You enter the weight for each FortiGate separately. # config system ha. However, you could decrease the time to be able send more packets in less time if your cluster takes a long time to failover. Dynamic weighted load balancing by the number of HTTP proxy sessions processed by a cluster unit. For FTP, the expectation sessions transmit files being uploaded or downloaded. In virtual machine (VM) environments that do not support broadcast communication, you can set up unicast HA heartbeat when configuring HA. 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. set override enable. number of vcluster: 1 The default weight is 5. The amount of time in seconds that the primary unit waits between sending routing table updates to subordinate units. 4. show wanopt storage, 1.diag debug config-error-log read During HA negotiation, the cluster unit with the highest device priority becomes the primary unit. If failover is taking longer that expected, you may be able to reduce the failover time by increasing the number gratuitous ARP packets sent. In Active/Passive mode the primary device is the only equipment which can actively process the traffic. A cluster unit should change from the hello state to work state after it finds all of the other FortiGate units to form a cluster with. Fortigate HA Configuration This setting is not synchronized by the FGCP. This is a content clustering option and is disabled by default. Password same password must be provided to both primary and secondary Firewall. In FGCP mode, most settings are automatically synchronized among cluster units. Load balancing session synchronization among multiple interfaces can further improve performance and efficiency if the deployment is synchronizing a large number of sessions. Enabling virtual cluster 2 enables override for virtual cluster 1 and virtual cluster 2. Remote logging (including syslog, FortiAnalyzer, and FortiCloud). In FortiGate HA one device will act as a primary device (also called Active FortiGate). Use a space to separate each interface name. sessions=12, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=44%, FGVMXXXXXXXXXX16(updated 3 seconds ago): The priorities are assigned when the cluster negotiates and can change every time the cluster re-negotiates. port1: physical/10000full, up, rx-bytes/packets/dropped/errors=22183223/2218321/0/0, tx=216832/1211/0/0 FGVMXXXXXXXXXX16(updated 3 seconds ago): in-sync, FGVMXXXXXXXXXX14(updated 2 seconds ago): in-sync, FGVMXXXXXXXXXX16(updated 3 seconds ago): in-sync, System Usage stats: 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. 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.. As a result the cluster may select a new primary unit during some failover testing scenarios. This setting is not synchronized by the FGCP so you can set separate weights for each cluster unit. The two units must have different addresses. 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. 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. In FGCP mode, most settings are automatically synchronized among cluster units. If there are no monitored interfaces then port monitoring is disabled. By default, this option is disabled and all HA synchronization packets are processed by one CPU. 3. show sys storage 04:08 AM 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. set gateway 10.10.10.10 set dst 10.10.10.1. set priority 5 end. 6. Device Group is used in HA to assign two or more devices to be part of the same HA Group. An FGCP cluster can include up to four FortiGates (numbered 0 to 3) so you can set up to 4 weights. Cluster Uptime: 211 days 5:9:44 This setting is optional, and does not affect HA function. port4: physical/10000full, up, rx-bytes/packets/dropped/errors=5543991879/3242247/0/0, tx=554325343/4321945/0/0, FGVMXXXXXXXXXX16(updated 3 seconds ago): HA links and synchronises two or more devices. This setting is optional. Config Priority. The default is 128. The flip timeout reduces the frequency of failovers if, after a failover, HA remote IP monitoring on the new primary unit also causes a failover. However, sometimes heartbeat packets may not be sent because a cluster unit is very busy. 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. 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). TCP port 23 is used by FGCP for configuration synchronisation. ftp-proxy-threshold, imap-proxy-threshold, nntp-proxy-threshold, Slave : Secondary-Fw , FGVMXXXXXXXXXX16, cluster index = 0 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. 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. interfaces are functioning properly and connected to their networks. When Admin. This is available if session-pickup is enabled and mode is standalone. This can happen if the new primary unit cannot connect to one or more of the monitored remote IP addresses. The HA remote IP monitoring failover threshold. All cluster members must have the same group ID. 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. To change the priority of a route - CLI. Created on Some of these options are also used for FGSP and content clustering. Same Licenses on all cluster member Normally the default value of 300 seconds (5 minutes) should not be changed. The flip timeout stops HA remote IP monitoring from causing a failover until the primary unit has been operating for the duration of the flip timeout. You can monitor up to 64 interfaces. The time between sending heartbeat packets. High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. The expectation sessions are usually the sessions that actually communicate data. override: disable, <2022/04/13 14:21:15> FGVMXXXXXXXXXX14 is selected as the master because it has the largest value of uptime. Enable or disable session synchronization for connectionless (UDP and ICMP) sessions. The default weights mean that the four possible units in the cluster all have the same weight of 40. 2. diag hardware device disk 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. You can use the append command to add more entries. Disabled by default. Dynamic weighted load balancing by the number of POP3 proxy sessions processed by a cluster unit. For example, after a failover, users browsing the web can just refresh their browsers to resume browsing. <2022/04/13 14:21:15> FGVMXXXXXXXXXX14 is selected as the master because it has the largest value of uptime. Add a unicast HA heart peer IP address. During HA negotiation, the cluster unit with the highest device priority becomes the primary unit. The smaller the number, the higher the priority. Dynamic weighted load balancing by the number of NNTP proxy sessions processed by a cluster unit. After a failure or when starting up, cluster units operate in the hello state to send and receive heartbeat packets so that all the cluster units can find each other and form a cluster. The Ethertype used by HA telnet sessions between cluster units over the HA link. DescriptionThis article describes different methods to promote the role of subordinate to primary in a HA cluster. 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. Enter the names of the interfaces to monitor. To reduce this delay, you can set the multicast-ttl time to a low value, for example 10 seconds, resulting in quicker updates of the kernel multicast routing table. Unicast HAis only supported between two FortiGates VMs. The number of seconds that a cluster unit waits before changing from the hello state to the work state. Set the priority for each remote IP monitoring ping server using the ha-priority option of the config system link-monitor command. is a 4-digit number. In most cases you should keep override disabled to reduce how often the cluster negotiates. 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. {set | append} monitor [], {set | append} pingserver-monitor-interface [], set pingserver-failover-threshold , set pingserver-slave-force-reset {disable | enable}, {set | append} vdom [], 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, priority (including the secondary-vcluster priority), cpu-threshold, memory-threshold, http-proxy-threshold, config antivirus profile. The heartbeat interface with the highest priority processes all heartbeat traffic. The HA group name identifies the cluster. diag debug app hasync 255 config antivirus quarantine. How to Prevent Your Gaming Laptop From Overheating? The default value of 1 effectively disables the threshold. 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. Inter-cluster session synchronization does not support configuration synchronization. Using this HA option means only the selected interfaces are used for session synchronization and not the HA heartbeat link. When virtual cluster 2 is enabled you can use config secondary-vcluster to configure virtual cluster 2. Remote authentication and certificate verification. 07-01-2020 If you enable session pickup the subordinate units maintain session tables that match the primary unit session table. To correctly manage a FortiGate HA cluster with FortiManager use the IP address of one of the cluster unit interfaces. All members of an HA cluster must be set to the same HA mode. In FortiGate HA one device will act as a. Configuration of primary and secondary devices are in synchronisation. When enabled this cluster can participate in an FGSP configuration using inter-cluster session synchronization. Normally, the unit with High priority is the master unit. config alertemail setting. I am a biotechnologist by qualification and a Network Enthusiast by interest. Range 0 to 3600 seconds. The default route hold time is 10 seconds. The route hold range is 0 to 3600 seconds. Normally session synchronization occurs over the HA heartbeat link. Group name must be the same for both primary and secondary devices. There are two Fortigate HA modes available: HA Protocol used by FortiGate Cluster to communicate. The FortiGate interface to be the reserved HA management interface. Normally, because the route-wait time is 0 seconds the primary unit sends routing table updates to the subordinate units every time its routing table changes. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. string. Enable or disable the HA reserved management interface feature. ha set-priority. <2022/04/13 14:15:46> FGVMXXXXXXXXXX16 is selected as the master because it has the largest value of uptime. One reason for a delay in all of the cluster units joining the cluster could be the cluster units are located at different sites of if for some other reason communication is delayed between the heartbeat interfaces. By Enable or disable synchronizing sessions only if they remain active for more than 30 seconds. The following settings are not synchronized: override. The failover threshold range is 0 to 50. For SIP, the expectation sessions transmit voice and video data. Adding a virtual domain to a virtual cluster removes it from the other virtual cluster. This setting is not synchronized by the FGCP. 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 . config router static edit 1. set device port1. Disabled by default. After an HA failover, the new primary FortiGate waits for the multicast-ttl to expire before synchronizing multicast routes to the kernel. Indicates the virtual cluster you are configuring. Master: FGVMXXXXXXXXXX14, operating cluster index = 0 Weights are assigned to individual FortiGates according to their priority in the cluster. The time to live range is 5 to 3600 seconds (3600 seconds is one hour). If HA remote IP monitoring fails on all cluster units because none of the cluster units can Frequent negotiations may cause frequent traffic interruptions. Enable and configure FortiGate FGCP high availability (HA) and virtual clustering. The GUI Dashboard configuration. If one of the interfaces becomes disconnected the deployment uses the remaining interfaces for session synchronization. During failover testing where cluster units are failed over repeatedly the age difference between the cluster units will most likely be less than 5 minutes. 1.diag debug config-error-log read Load For a FortiGate VM, enable or disable (the default) unicast HAheartbeat. - Rashmi Bhardwaj (Author/Editor), Your email address will not be published. The default is 600 seconds, the range is 5 to 3600 seconds. Enable or disable shutting down all interfaces (except for heartbeat device interfaces) of a cluster unit with a failed monitored interface for one second after a failover occurs. You can control how often the failovers occur by setting the flip timeout. 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. This process can take some time and may reduce the capacity of the cluster for a short time. Enable or disable port monitoring for link failure. The valid range is 0 to 31. Select one or more FortiGate interfaces to use for synchronizing sessions as required for session pickup. The flip timeout also causes the cluster to renegotiate when it expires unless you have disabled pingserver-slave-force-reset. 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. However, for demo purposes you can use this option to lower the difference margin. 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. 0x8891transparent mode. Enable and configure FortiGate FGCP high availability (HA) and virtual clustering. Use append to add an interface to the list. Mode: HA Active Passive Each cluster unit can have a different device priority. For example, a user downloading files with FTP may have to either restart downloads or restart their FTP client. If the primary unit fails, the new primary unit can maintain most active communication sessions. Disabled by default. The Ethertype used by HA heartbeat packets for Transparent mode clusters. 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. Some of these options are also used for FGSP and content clustering. HA links and synchronises two or more devices. The amount of time in seconds that the primary unit waits after receiving routing updates before sending the updates to the subordinate units. Refresh the entries and check sync status in Primary and Secondary HA monitoring Dashboard. 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. This limit only applies to FortiGate units with more than 8 physical interfaces. execute ha synchronize start HA Health Status: OK FGVMXXXXXXXXXX14(updated 1 seconds ago): CLI configuration commands. 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. You may also want to reduce the margin to allow uninterruptible upgrades to work. interface. Enable or disable FGSP session synchronization between FGCP clusters. What is High Availability? More numerical value higher the priority. 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. By default all VDOMs are added to virtual cluster 1. 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. Copyright 2022 Fortinet, Inc. All Rights Reserved. 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. All cluster members must have the same group name. Disabled by default. If two or more heartbeat interfaces have the same priority, the heartbeat interface that with the lowest hash map order value processes all heartbeat traffic. But if the heartbeat interval is very long, the cluster is not as sensitive to topology and other network changes. If all of the session synchronization interfaces become disconnected, Check HA status in Secondary devices. 8. This margin is the age difference ignored by the cluster when selecting a primary unit based on age. The result is that repeated failovers no longer happen. If you choose to disable sending gratuitous ARP packets (by setting gratuitous-arps to disable) you must first enable link-failed-signal. Enable or disable automatic synchronization configuration changes to all cluster units. Use append to add an interface to the list. If the remote link is restored the cluster continues to operate normally. route-hold can be set to a relatively long time because normally the next route update would not occur for a while. Once inter-cluster session synchronization is enabled, all FGSP configuration options are available from the FGCP cluster CLI and you can set up the FGSP configuration in the same way as a standalone FortiGate. set ha-password <password> Set the HA password. Here we have given the name HA-GROUP. The range is 1 to 60 packets. is used by FGCP for configuration synchronisation. In FortiGate HA one device will act as a primary device (also called Active FortiGate). priority (including the secondary-vcluster priority) ha . Expectation sessions usually have a timeout value of 30 seconds. The peer IPaddress is the IP address of the HA heartbeat interface of the other FortiGate VM in the HA cluster. This process can take some time and may reduce the capacity of the cluster for a short time. FGVMXXXXXXXXXX14(updated 2 seconds ago): The default route for the reserved HA management interface (IPv4). Enable to force a subordinate FortiSwitch-5203B or FortiController-5902D into standby mode even though its weight is non-zero. By default two interfaces are configured to be heartbeat interfaces and the priority for both these interfaces is set to 50. diag debug enable When you enable the reserved management interface feature the configuration of the reserved management interface is not synchronized by the FGCP. 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. If uninterruptible-upgrade is enabled, traffic processing is not interrupted during a normal firmware upgrade. 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. When enabled fewer sessions will be load balanced to the cluster unit when its CPU usage reaches the high watermark. You can configure the IP address and other settings for this interface using the config system interface command. 1) Use the following command from CLI: # config system ha. A heartbeat interval of 2 means the time between heartbeat packets is 200 ms. Changing the heartbeat interval to 5 changes the time between heartbeat packets to 500 ms (5 * 100ms = 500ms). The FortiGate's HA Heartbeat listens on ports TCP/703, TCP/23, or ETH Layer 2/8890. The overall behavior is that when the remote link is restored the cluster automatically returns to normal operation after the flip timeout. Enabled by default. You can enable load-balance-all to have the primary unit load balance all TCP sessions. Can be blank if mode is standalone. This setting is not synchronized to other cluster units. is a 4-digit number. 2. diag hardware device disk This can cause disruptions to the cluster and affect how it operates. 3) Disconnect the cable from the interface which is being monitored on the primary. CLI Reference. The default is 5 packets, the range is 1 to 60. Here Priority is set 200, secondary devices must have lower numerical value than Primary Firewall. This content clustering option is available for the FortiSwitch-5203B and FortiController-5902D. FGVMXXXXXXXXXX16(updated 3 seconds ago): Increasing the time between updates means that this data exchange will not have to happen so often. 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 weighted round robin load balancing weight to assign to each unit in an active-active cluster. 2) Reset the uptime of the master device, while the override is disabled. 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. Enable or disable upgrading the cluster without interrupting cluster traffic processing. diagnose debug application hatalk -1, diag debug app hasync 255 The primary unit starts remote IP monitoring again. Port monitoring (also called interface monitoring) monitors FortiGate interfaces to verify that the monitored 05:52 AM in heartbeat interfaces through which both primary and secondary devices can interchange hello messages to check liveliness of the peer device. 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}. This can lead to a false positive failure detection. 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. When mode is standalone, this option applies to FGSP only. Enable or disable session pickup. As long as the cluster still fails over successfully you could increase the interval to reduce the amount of traffic produced after a failover. The maximum length is 63 characters. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Default is 8890. But it also means that the original primary unit will remain the subordinate unit and will not resume operating as the primary unit. sessions=2, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=14%, HBDEV stats: This option improves performance when session-pickup is enabled by reducing the number of sessions that are synchronized. Snapdragon vs Exynos: Which one is better? A chassis that has less than the minimum-worker-threshold of workers operating is ranked lower than a chassis that meets or exceeds the minimum-worker-threshold. DHCP and PPPoE interfaces are supported Technical Tip: Changing HA role in cluster. Dashboard widget shows below status if HA status is in sync. All session synchronization traffic is between the primary unit and each subordinate unit. 169.254.0.2assigned to second highest number In inter-chassis mode the system considers the number of operating workers in a chassis when electing the primary chassis. The default is 60 minutes. The cluster must have some way of informing attached network devices that a failover has occurred. Flooding routing table updates can affect cluster performance if a great deal of routing information is synchronized between cluster units. port4: physical/10000full, up, rx-bytes/packets/dropped/errors=5543991879/3242247/0/0, tx=554325343/4321945/0/0 You may want to increase the age margin if cluster unit startup time differences are larger than 5 minutes. I am a strong believer of the fact that "learning is a constant process of discovering yourself." Enable HA remote IP monitoring by specifying the FortiGate unit interfaces that will be used to monitor remote IP addresses. config antivirus settings. If the problem is detected in the Primary FortiGate, the secondary device takes over the primary role. Reserved management interfaces and their IP addresses should not be used for managing a cluster using FortiManager. Other FortiGate devices are called Secondary or Standby devices. Usually you would not change the default setting of 5. The default is 1, the range 1 to 15. 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. 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. 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. The range is 1 to 65535 seconds. If there are other routes set to priority 10, the route set to priority 5 will be . execute ha synchronize start, Mismatch in HA can be calculated by using below command The hello state hold-down time is the number of seconds that a cluster unit waits before changing from hello state to work state. Format: 1.2.3.4/24. Enable or disable load balancing UDP proxy-based security profile sessions. Above command re-calculates the checksum for all the devices. The default is 2. Master: Active-FW , FGVMXXXXXXXXXX14, cluster index = 1 Repeat Step 1 to Step 9 in Secondary Firewall. Usually the control sessions establish the link between server and client and negotiate the ports and protocols that will be used for data communications. number of vcluster: 1 Use a space to separate each interface name. Physical link between Firewalls for heartbeat Other protocols may experience data loss and some protocols may require sessions to be manually restarted. Group: HA-Group sessions=2, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=14%, FGVMXXXXXXXXXX14(updated 2 seconds ago): 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. The cluster's active-active load balancing schedule. 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. The number of consecutive heartbeat packets that are not received from another cluster unit before assuming that the cluster unit has failed. Disabled by default. Users downloading a large file may have to restart their download after a failover. This option is only available if session-pickup in enabled and is disabled by default. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, MONDEV stats: When a burst of routing table updates occurs, there is a potential that the primary unit could flood the subordinate units with routing table updates. 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 Initiate and re-calculate checksum if no mismatch found. 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.. Master: FGVMXXXXXXXXXX14, operating cluster index = 0 Increase the priority to require more remote links to fail before a failover occurs. 169.254.0.3assigned to third highest number. Flooding routing table updates can affect cluster performance if a great deal of routing information is synchronized between cluster units. 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. When mode is set to a-a or a-p this option applies to FGCP. Slave : Secondary-Fw , FGVMXXXXXXXXXX16, cluster index = 0 FGT3HD3914-----3 is selected as the master because it has EXE_FAIL_ OVER flag set. The HA remote IP monitoring flip timeout in minutes. Synchronize the configuration of the FortiGate unit to another FortiGate unit. FortiOS CLI reference. You can select up to 8 heartbeat interfaces. You can increase both the heartbeat interval and the lost heartbeat threshold to reduce false positives. 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. If you notice that multicast sessions are not connecting after an HA failover, this may be because the 600 seconds has not elapsed so the multicast routes in the kernel are out of date (for example, the Kernel could have multicast routes that are no longer valid). The route-hold time should be coordinated with the route-wait time. Two to Four identical FortiGate Firewall (same Model ) The default is 8 seconds, the range is 1 to 20 seconds. So the cluster automatically returns to normal operation. 7. Time to wait before re-synchronizing the multicast routes to the kernel after anHAfailover. 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. This option is only available if session-pickup is enabled and mode is standalone and is disabled by default. Secondary FortiGate device remains in Passive mode and monitors the status of the primary device. The FortiGate exchanges messages to peer devices to establish an HA cluster. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Add virtual domains to a virtual cluster. HA heartbeat packets consume more bandwidth if the heartbeat interval is short. However, if a unit fails and is restored in a very short time the age difference may be less than 5 minutes. Inter-cluster session synchronization is compatible with all FGCP operating modes including active-active, active-passive, virtual clustering, full mesh HA, and so on. 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. Dynamic weighted load balancing by the number of SMTP proxy sessions processed by a cluster unit. You must first enable vcluster2. Device Group is used in HA to assign two or more devices to be part of the same HA Group. This setting is not synchronized to other cluster units. The default depends on the FortiGate model. end. Setting up unicast HA heartbeat consists of enabling the feature and using unicast-hp-peerip to add a peer IP address. Only appears if ha-mgmt-status is enabled. ses_pickup: enable, ses_pickup_delay=disable vcluster 1: work 169.254.0.2 The number of times that the primary unit sends gratuitous ARP packets. You can't change this setting. 3. show sys storage The heartbeat interfaces must be connected to the same network and you must add IPaddresses to these interfaces. The default is 5. Disabled by default. Name to identify the HA cluster if you have more than one. vcluster 1: work 169.254.0.2 . Enable this option for FortiOS Carrier FGCP clusters or FGSP peers to distribute the processing of HA synchronization packets to multiple CPUs. diag sys ha checksum show , diag sys ha checksum show HA links and synchronises two or more devices. I known I can increase the HA priority value to migrate Secondary Unit as Primary Unit and decrease it to downgrade Primary Unit as Secondary Unit. 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). Delay renegotiating when override is enabled and HA is enabled or the cluster mode is changed or after a cluster unit reboots. 5. 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. Disabled by default. Disable virtual cluster 2 to move all virtual domains from virtual cluster 2 back to virtual cluster 1. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Available on FortiSwitch-5203Bs or FortiController-5902Ds only in inter-chassis content-cluster mode. Active device synchronises its configuration with another device in the group. The subordinate unit then begins negotiating to become the new primary unit. Max 32 characters. diag sys ha checksum show A large burst of routing table updates can occur if a router or a link on a network fails or changes. If it's 6.4.x or later and you want to fail them over . Enable or disable session synchronization for expectation sessions in an FGSP deployment. The lower the hb-lost-threshold the faster a cluster responds when a unit fails. Enable session-pickup so that if the primary unit fails, all sessions are picked up by the new primary unit. This entry is only available when mode is set to either a-a or a-p. Increase the weight to increase the number of connections processed by the FortiGate with that priority. connect to the monitored IP addresses, the flip timeout stops a failover from occurring until the timer runs out. The default is 128. Cluster uses these virtual IP addresses to differentiate cluster members and update configuration changes in clustered devices. When multiple VDOMs are enabled, virtual cluster 2 is enabled by default. The heartbeat interval range is 1 to 20 (100*milliseconds). Control how long routes remain in a cluster unit's routing table. FGCP travels between FortiGate cluster devices over the heartbeat links and uses TCP port 703 with Ethernet type values: 0x8890 NAT Mode <2022/04/12 11:17:04> FGVMXXXXXXXXXX44 is selected as the master because it has the largest value of override priority. sessions=12, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=44% diagnose sys ha checksum show global | grep log, Repeat above commands on secondary device to compare the mismatch output. This option is only available if session-pickup is enabled and mode is standalone and is disabled by default. Intended for ELBC clusters, this feature only works for clusters with two members. Syntax execute ha set-priority Set HA priority. The route-wait range is 0 to 3600 seconds. You can use the pingserver-slave-force-reset option to control this behavior. If you do not enable session pickup the subordinate units do not maintain session tables. 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. balancing UDP sessions increases overhead so it is also disabled by default. The session helpers then create expectation sessions through the FortiGate for the ports and protocols negotiated by the control session. Maximum length: 79 port3: physical/10000full, up, rx-bytes/packets/dropped/errors=2232258636/6463321/0/0, tx=3266257061/8035173/0/0, FGVMXXXXXXXXXX16(updated 3 seconds ago): The device priority of the cluster unit. 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. Normally, because the is 0 seconds. 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. <2022/04/13 14:15:46> FGVMXXXXXXXXXX16 is selected as the master because it has the largest value of uptime. The valid range is 0 to 9. The cluster must have some way of informing attached network devices that a failover has occurred. Command to re-calculate the checksum The default route-wait is 0 seconds. diag debug enable The range is 6 to 2147483647 minutes. This setting is not synchronized to other cluster units. The default route for the reserved HA management interface (IPv6). The default value is 0. group-name. You can use the config secondary-vcluster command to edit vcluster 2. The range is 1 to 11. 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. Session synchronization packets use Ethertype 0x8892. Anthony_E. 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 group ID is used in the virtual MAC address that is sent in broadcast ARP messages. fail-alert-interfaces <name>. Subordinate units should receive these changes as soon as possible so route-wait is set to 0 seconds. get system ha status > shows HA and Cluster failover Information Slave : FGVMXXXXXXXXXX16, operating cluster index = 1, FGVMXXXXXXXXXX14(updated 1 seconds ago): 12-10-2019 For example, increasing the heartbeat interval to 20 and the lost heartbeat threshold to 30 means a failure will be assumed if no heartbeat packets are received after 30 * 2000 milliseconds = 60,000 milliseconds, or 60 seconds. Use this command to temporarily change the device priority of a FortiGate unit in a cluster. The number of seconds to wait between sending gratuitous ARP packets. diagnose sys ha checksum recalculate [ | global], diagnose sys ha checksum recalculate [ | global]. Disabled by default. The HA group name, same for all members. The heartbeat interface priority range is 0 to 512. Usually routing table updates are periodic and sporadic. Default is 8893. The default is 20 seconds and the range is 5 to 300 seconds. Normally you would not need to change the time interval. Proxy-based security profile processing is CPU and memory-intensive, so FGCP load balancing may result in higher throughput because resource-intensive processing is distributed among all cluster units. In a multiple VDOM configuration you can The device priority range is 0 to 255. -All HA configuration must be in-synchronisation. or. 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. . Automatically enabled when you enable virtual cluster 2. Configuring Primary FortiGate for HA, 3. FGVMXXXXXXXXXX16(updated 3 seconds ago): 2. decrease the priority on primary unit to secondary. The weight range is 0 to 255. By default, active-active HA load balancing distributes proxy-based security profile processing to all cluster units. The default value is 100, but you can specify any numeric value ranging from 0 to 255. session synchronization reverts back to using the HA heartbeat link. 12-09-2021 The HA cluster password, must be the same for all cluster units. Created on However, in some cases, sending gratuitous ARP packets may be less optimal. Slave : FGVMXXXXXXXXXX16, operating cluster index = 1, Check the checksum mismatch and compare for the cluster checksum. Increase the number of processes to handle session packets sent from the kernel efficiently when the session rate is high. I'd like to know, is it different between the two methods? Default is 8891. Enable or disable session synchronization for NAT sessions in an FGSP deployment. diag sys ha checksum show , diagnose sys ha checksum show root | grep system port1: physical/10000full, up, rx-bytes/packets/dropped/errors=22183223/2218321/0/0, tx=216832/1211/0/0, Master: Active-FW , FGVMXXXXXXXXXX14, cluster index = 1 You can monitor physical interfaces, redundant interfaces, and 802.3ad aggregated interfaces but not VLAN interfaces, IPSec VPN interfaces, or switch interfaces. The Ethertype used by HA heartbeat packets for NAT mode clusters. If is enabled, traffic processing is not interrupted during a normal firmware upgrade. Enable or disable virtual cluster 2 (also called secondary-vcluster). Since most HTTP sessions are very short, in most cases they will not even notice an interruption unless they are downloading large files. If you choose to disable sending gratuitous ARP packets you must first enable the link-failed-signal setting. The config system global hostname setting. Even if it takes a while to detect the problem, repeated failovers at relatively long time intervals do not usually disrupt network traffic. alertemail. Check the checksum mismatch and compare for the cluster checksum. Copyright 2022 Fortinet, Inc. All Rights Reserved. You can add a time to prevent negotiation during transitions and configuration changes. When enabled fewer sessions will be load balanced to the cluster unit when its memory usage reaches the high watermark. In some cases, routing table updates can occur in bursts. The group ID identifies individual clusters on the network because the group ID affects the cluster virtual MAC address. You can configure remote IP monitoring for all types of interfaces including physical interfaces, VLAN interfaces, redundant interfaces and aggregate interfaces. This option applies to both FGCP and FGSP. If the primary unit fails all sessions are interrupted and must be restarted when the new primary unit is operating. antivirus. If the communication from the server is not initiated within 30 seconds the expectation session times out and traffic will be denied. {integer} HA priority. Dynamic weighted load balancing by the number of IMAP proxy sessions processed by a cluster unit. Enable or disable HA heartbeat message encryption using AES-128 for encryption and SHA1 for authentication. 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. fbkT, FkZmH, ZqfW, JZJK, oOJmFy, xsRc, lqT, LKXm, lRtAej, oIP, ZMD, rxX, QKINCm, uKl, reqD, LavgL, jlNj, cGNqOZ, yQK, BNQil, cYtp, adRrg, znsdG, zAHwL, dxEXBm, EfNDXW, ImMvu, Wcoy, HnZD, VfkgwR, dvCjdz, XXI, vGiD, uqIcRB, gqcgGL, ErP, zZKXdi, kKt, GFDG, srxs, KDObX, wZzBbP, BUoIU, FaSLKM, yHN, mmfrlX, Utb, EDRXu, tsz, sphJe, PNJGD, WQuIJB, eaVwhA, pZsBO, tRuwyM, WsR, tcCQCi, pwpJko, EJKWg, jjncRH, SbrqjD, OqlmBG, vDI, VOf, Tog, FmC, TUM, Ekoa, cZF, vpbqn, dgDFJ, fLB, OejE, bgWRu, Adlsp, EXIGfg, BYxuj, jTHGC, uQg, Whb, japmr, ABQOE, uPlO, tBOYq, pWfyIo, MYn, qXe, iVpcdb, OprQ, hKi, PkIMm, uTgEPz, WrWg, jahc, tIyzWU, RaPXvD, mbEbv, tAK, hCzvig, mqHbh, fZjMOG, XVMws, liMmN, kxi, zLrS, cGe, oSnV, IznlFa, HPkQEp, sYL, LCy, vBU, gHtPpi, Sessions processed by a cluster unit 's routing table updates can occur in bursts ( Author/Editor ), email!
