Inter-cluster session synchronization does not support configuration synchronization. Port monitoring (also called interface monitoring) monitors FortiGate interfaces to verify that the monitored 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. Disabled by default. Weights are assigned to individual FortiGates according to their priority in the cluster. The device priority range is 0 to 255. Slave : Secondary-Fw , FGVMXXXXXXXXXX16, cluster index = 0 Use a space to separate each interface name. The HA group name, same for all members. sessions=12, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=44%, FGVMXXXXXXXXXX16(updated 3 seconds ago): TCP port 23 is used by FGCP for configuration synchronisation. config antivirus quarantine. To correctly manage a FortiGate HA cluster with FortiManager use the IP address of one of the cluster unit interfaces. Maximum length: 79 The default is 5 packets, the range is 1 to 60. diag debug app hasync 255 Master: Active-FW , FGVMXXXXXXXXXX14, cluster index = 1 This setting is not synchronized by the FGCP. Slave : Secondary-Fw , FGVMXXXXXXXXXX16, cluster index = 0 In FGCP mode, most settings are automatically synchronized among cluster units. Cluster state change time: 2022-04-16 14:21:15, Master selected using: This process can take some time and may reduce the capacity of the cluster for a short time. 0x8891transparent mode. If the primary unit fails, the new primary unit can maintain most active communication sessions. monitor up to 64 interfaces per virtual cluster. The Ethertype used by HA heartbeat packets for Transparent mode clusters. 169.254.0.2assigned to second highest number Unicast HAis only supported between two FortiGates VMs. Session synchronization packets use Ethertype 0x8892. Default low and high watermarks of 0 disable the feature. 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. In most cases you should keep override disabled to reduce how often the cluster negotiates. The number of times that the primary unit sends gratuitous ARP packets. In FortiGate HA one device will act as a primary device (also called Active FortiGate). Disabled by default. 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. The weighted round robin load balancing weight to assign to each unit in an active-active cluster. 2. decrease the priority on primary unit to secondary. Add a unicast HA heart peer IP address. Dynamic weighted load balancing by the number of IMAP proxy sessions processed by a cluster unit. For SIP, the expectation sessions transmit voice and video data. By default two interfaces are configured to be heartbeat interfaces and the priority for both these interfaces is set to 50. When mode is standalone, this option applies to FGSP only. Device Group is used in HA to assign two or more devices to be part of the same HA Group. However, sometimes heartbeat packets may not be sent because a cluster unit is very busy. Select the FortiGate interfaces to be heartbeat interfaces and set the heartbeat priority for each interface. Enable or disable HA heartbeat message encryption using AES-128 for encryption and SHA1 for authentication. Usually the control sessions establish the link between server and client and negotiate the ports and protocols that will be used for data communications. By default, this option is disabled and all HA synchronization packets are processed by one CPU. The default is 128. Enable or disable session synchronization for NAT sessions in an FGSP deployment. ha set-priority. The smaller the number, the higher the priority. -All HA configuration must be in-synchronisation. Once a routing table update is sent, the primary unit waits the route-hold time before sending the next update. Other features enabled in security policies such as Endpoint security, traffic shaping and authentication have no effect on active-active load balancing. If one of the interfaces becomes disconnected the deployment uses the remaining interfaces for session synchronization. The number of processes used by the HA session sync daemon. Once Active-Passive mode selected multiple parameters are required. You can select up to 8 heartbeat interfaces. 8. sessions=12, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=44% Max 32 characters. Many protocols can successfully restart sessions with little, if any, loss of data. is a 4-digit number. Enter the names of the interfaces to monitor. Enabled by default. Format: 1.2.3.4/24. Select one or more FortiGate interfaces to use for synchronizing sessions as required for session pickup. Disabled by default. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. The default is 1, the range 1 to 15. 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}. diag sys ha checksum show , diagnose sys ha checksum show root | grep system set override disable. For a FortiGate VM, enable or disable (the default) unicast HAheartbeat. Enabling virtual cluster 2 enables override for virtual cluster 1 and virtual cluster 2. The default value is 0. group-name. in heartbeat interfaces through which both primary and secondary devices can interchange hello messages to check liveliness of the peer device. override: disable, Configuration Status: Debug: 0 You can monitor physical interfaces, redundant interfaces, and 802.3ad aggregated interfaces but not VLAN interfaces, IPSec VPN interfaces, or switch interfaces. is used by FGCP for configuration synchronisation. 12-09-2021 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. set ha-password <password> Set the HA password. Copyright 2022 Fortinet, Inc. All Rights Reserved. Usually routing table updates are periodic and sporadic. The range is 6 to 2147483647 minutes. The default is 600 seconds, the range is 5 to 3600 seconds. override: disable, <2022/04/13 14:21:15> FGVMXXXXXXXXXX14 is selected as the master because it has the largest value of uptime. You may also want to reduce the margin to allow uninterruptible upgrades to work. port4: physical/10000full, up, rx-bytes/packets/dropped/errors=5543991879/3242247/0/0, tx=554325343/4321945/0/0 The HA group name identifies the cluster. ses_pickup: enable, ses_pickup_delay=disable This option is only available if session-pickup is enabled and mode is standalone and is disabled by default. This setting is optional. 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. If you select more than one interface, session synchronization traffic is load balanced among the selected interfaces. In inter-chassis mode the system considers the number of operating workers in a chassis when electing the primary chassis. In FortiGate HA one device will act as a. Configuration of primary and secondary devices are in synchronisation. A large burst of routing table updates can occur if a router or a link on a network fails or changes. 3. show sys storage Refresh the entries and check sync status in Primary and Secondary HA monitoring Dashboard. You can control how often the failovers occur by setting the flip timeout. 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 Technical Tip: Changing HA role in cluster. Default is 8890. The two units must have different addresses. 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. Load balancing session synchronization among multiple interfaces can further improve performance and efficiency if the deployment is synchronizing a large number of sessions. Disabled by default. Using this HA option means only the selected interfaces are used for session synchronization and not the HA heartbeat link. Increasing the time between updates means that this data exchange will not have to happen so often. Names of the FortiGate interfaces to which the link failure alert is sent. Use append to add an interface to the list. This setting is optional, and does not affect HA function. 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. Enable to force a subordinate FortiSwitch-5203B or FortiController-5902D into standby mode even though its weight is non-zero. Group name must be the same for both primary and secondary devices. This limit only applies to FortiGate units with more than 8 physical interfaces. The default is 128. FGVMXXXXXXXXXX14(updated 1 seconds ago): ftp-proxy-threshold, imap-proxy-threshold, nntp-proxy-threshold, - Rashmi Bhardwaj (Author/Editor), Your email address will not be published. number of vcluster: 1 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 Default is 8891. This setting is not synchronized to other cluster units. FortiGate (global) # get sys ha status The default is 2. The HA group ID, same for all members, from 0 to 255. Snapdragon vs Exynos: Which one is better? Use this command to temporarily change the device priority of a FortiGate unit in a cluster. Dynamic weighted load balancing by the number of NNTP proxy sessions processed by a cluster unit. Configure virtual cluster 2 using the following syntax. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Users downloading a large file may have to restart their download after a failover. is a 4-digit number. 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. Run command to go in rough for discrepancy VDOMs by using command: The valid range is 0 to 31. 3) Disconnect the cable from the interface which is being monitored on the primary. or. The weight range is 0 to 255. You can use the config secondary-vcluster command to edit vcluster 2. ses_pickup: enable, ses_pickup_delay=disable The device priority of the cluster unit. This option improves performance when session-pickup is enabled by reducing the number of sessions that are synchronized. HA heartbeat packets consume more bandwidth if the heartbeat interval is short. The group ID identifies individual clusters on the network because the group ID affects the cluster virtual MAC address. Enable or disable session synchronization between FGCP clusters. You enter the weight for each FortiGate separately. This setting is not synchronized to other cluster units. 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. config alertemail setting. interfaces are functioning properly and connected to their networks. Disabled by default. Load Here we have given the name HA-GROUP. The lower the hb-lost-threshold the faster a cluster responds when a unit fails. Password same password must be provided to both primary and secondary Firewall. When Admin. 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. port4: physical/10000full, up, rx-bytes/packets/dropped/errors=5543991879/3242247/0/0, tx=554325343/4321945/0/0, FGVMXXXXXXXXXX16(updated 3 seconds ago): To change the priority of a route - CLI. However, in some cases, sending gratuitous ARP packets may be less optimal. 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. <2022/04/12 11:17:04> FGVMXXXXXXXXXX44 is selected as the master because it has the largest value of override priority. However, if a unit fails and is restored in a very short time the age difference may be less than 5 minutes. I'd like to know, is it different between the two methods? The GUI Dashboard configuration. Configuring Primary FortiGate for HA, 3. The default route for the reserved HA management interface (IPv4). 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). Dynamic weighted load balancing by the number of HTTP proxy sessions processed by a cluster unit. 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. FortiOS CLI reference. DescriptionThis article describes different methods to promote the role of subordinate to primary in a HA cluster. The result is that repeated failovers no longer happen. The FortiGate interface to be the reserved HA management interface. connectivity can be lost with the FortiGate as the HA cluster negotiates and the FGCP initiate new MAC address of the FortiGate interfaces. If there are no monitored interfaces then port monitoring is disabled. Enable and configure FortiGate FGCP high availability (HA) and virtual clustering. Model: FortiGate-VM64-KVM FGVMXXXXXXXXXX16(updated 3 seconds ago): All session synchronization traffic is between the primary unit and each subordinate unit. Flooding routing table updates can affect cluster performance if a great deal of routing information is synchronized between cluster units. antivirus. What is High Availability? Delay renegotiating when override is enabled and HA is enabled or the cluster mode is changed or after a cluster unit reboots. 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. Cluster uses these virtual IP addresses to differentiate cluster members and update configuration changes in clustered devices. 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. Dynamic weighted load balancing by the number of POP3 proxy sessions processed by a cluster unit. You may want to reduce the margin if during failover testing you dont want to wait the default age difference margin of 5 minutes. Above command re-calculates the checksum for all the devices. diag sys ha checksum show 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. By default all VDOMs are added to virtual cluster 1. As a result the cluster may select a new primary unit during some failover testing scenarios. diag sys ha checksum show , diag sys ha checksum show When you enable the reserved management interface feature the configuration of the reserved management interface is not synchronized by the FGCP. 6. Add virtual domains to a virtual cluster. There may also be a number of reasons to set the interval higher. vcluster 1: work 169.254.0.2 The heartbeat interface with the highest priority processes all heartbeat traffic. This setting is not synchronized to other cluster units. 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. Some of these options are also used for FGSP and content clustering. In FGCP mode, most settings are automatically synchronized among cluster units. CLI Reference. Device Group Group name must be the same for both primary and secondary devices. Increase the priority to require more remote links to fail before a failover occurs. FGVMXXXXXXXXXX14(updated 2 seconds ago): in-sync In some cases, however, you might want to reduce the number of gratuitous ARP packets. Inter-cluster session synchronization is compatible with all FGCP operating modes including active-active, active-passive, virtual clustering, full mesh HA, and so on. 1.diag debug config-error-log read The following settings are not synchronized: override. If you have more than two clusters on the same network they must have different Group IDs. You can add a time to prevent negotiation during transitions and configuration changes. Dashboard widget shows below status if HA status is in sync. 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. The amount of time in seconds that the primary unit waits between sending routing table updates to subordinate units. 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. This margin is the age difference ignored by the cluster when selecting a primary unit based on age. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, FGVMXXXXXXXXXX14(updated 2 seconds ago): priority (including the secondary-vcluster priority) ha . Each cluster unit can have a different device priority. 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. Normally the default value of 300 seconds (5 minutes) should not be changed. set override enable. The heartbeat interface priority range is 0 to 512. 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. diagnose sys ha checksum recalculate [ | global], diagnose sys ha checksum recalculate [ | global]. Enable or disable sending gratuitous ARP packets from a new primary unit. . If uninterruptible-upgrade is enabled, traffic processing is not interrupted during a normal firmware upgrade. Load balancing TCP sessions increases overhead and may actually reduce performance so it is disabled by default. Enable HA remote IP monitoring by specifying the FortiGate unit interfaces that will be used to monitor remote IP addresses. Enable or disable virtual cluster 2 (also called secondary-vcluster). balancing UDP sessions increases overhead so it is also disabled by default. Adding a virtual domain to a virtual cluster removes it from the other virtual cluster. 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. Use append to add an interface to the list. For example, if you have a cluster of FortiGate units in Transparent mode, after a failover the new primary unit will send gratuitous ARP packets to all of the addresses in its Forwarding Database (FDB). config antivirus settings. Time to wait before re-synchronizing the multicast routes to the kernel after anHAfailover. Even if it takes a while to detect the problem, repeated failovers at relatively long time intervals do not usually disrupt network traffic. You can increase both the heartbeat interval and the lost heartbeat threshold to reduce false positives. 4. show wanopt storage, 1.diag debug config-error-log read sessions=2, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=14%, FGVMXXXXXXXXXX14(updated 2 seconds ago): This setting is not synchronized by the FGCP so you can set separate weights for each cluster unit. Here we have given the name HA-GROUP.
