Once Active-Passive mode selected multiple parameters are required. Physical link between Firewalls for heartbeat monitor up to 64 interfaces per virtual cluster. FGT3HD3914-----3 is selected as the master because it has EXE_FAIL_ OVER flag set. 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. 169.254.0.2assigned to second highest number In Active/Passive mode the primary device is the only equipment which can actively process the traffic. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, MONDEV stats: ses_pickup: enable, ses_pickup_delay=disable port1: physical/10000full, up, rx-bytes/packets/dropped/errors=22183223/2218321/0/0, tx=216832/1211/0/0 You can monitor up to 64 interfaces. Default is 8891. Enable to force a subordinate FortiSwitch-5203B or FortiController-5902D into standby mode even though its weight is non-zero. 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. In some cases, routing table updates can occur in bursts. 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. is a 4-digit number. 2) Reset the uptime of the master device, while the override is disabled. The subordinate unit then begins negotiating to become the new primary unit. Active device synchronises its configuration with another device in the group. Enable or disable virtual cluster 2 (also called secondary-vcluster). 2. decrease the priority on primary unit to secondary. Reserved management interfaces and their IP addresses should not be used for managing a cluster using FortiManager. Slave : FGVMXXXXXXXXXX16, operating cluster index = 1, FGVMXXXXXXXXXX14(updated 1 seconds ago): balancing UDP sessions increases overhead so it is also disabled by default. High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. This option applies to both FGCP and FGSP. Add virtual domains to a virtual cluster. 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. 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. This process can take some time and may reduce the capacity of the cluster for a short time. To change the priority of a route - CLI. override: disable, Configuration Status: 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. set gateway 10.10.10.10 set dst 10.10.10.1. set priority 5 end. However, sometimes heartbeat packets may not be sent because a cluster unit is very busy. 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. is a 4-digit number. I am a strong believer of the fact that "learning is a constant process of discovering yourself." diag debug enable diag sys ha checksum show , diagnose sys ha checksum show root | grep system <2022/04/12 11:17:04> FGVMXXXXXXXXXX44 is selected as the master because it has the largest value of override priority. vcluster 1: work 169.254.0.2 Can be blank if mode is standalone. You can enable load-balance-all to have the primary unit load balance all TCP sessions. Other features enabled in security policies such as Endpoint security, traffic shaping and authentication have no effect on active-active load balancing. Created on Increase the weight to increase the number of connections processed by the FortiGate with that priority. The heartbeat interface with the highest priority processes all heartbeat traffic. set ha-password <password> Set the HA password. 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 mode is set to a-a or a-p this option applies to FGCP. This option is available when mode is a-a and schedule is weight-round-robin. Use a space to separate each interface name. The number of seconds to wait between sending gratuitous ARP packets. Since most HTTP sessions are very short, in most cases they will not even notice an interruption unless they are downloading large files. This setting is not synchronized to other 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. 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. This margin is the age difference ignored by the cluster when selecting a primary unit based on age. The following command changes the priority to 5 for a route to the address 10.10.10.1 on the port1. The number of processes used by the HA session sync daemon. sessions=12, average-cpu-user/nice/system/idle=0%/0%/0%/100%, memory=44% Remote authentication and certificate verification. interface. If there are no monitored interfaces then port monitoring is disabled. However, in some cases, sending gratuitous ARP packets may be less optimal. 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. Even if it takes a while to detect the problem, repeated failovers at relatively long time intervals do not usually disrupt network traffic. The default is 128. The HA group ID, same for all members, from 0 to 255. Default is 8893. The range is 1 to 11. Normally the default value of 300 seconds (5 minutes) should not be changed. 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. 8. The cluster must have some way of informing attached network devices that a failover has occurred. Above command re-calculates the checksum for all the devices. When virtual cluster 2 is enabled you can use config secondary-vcluster to configure virtual cluster 2. If HA remote IP monitoring fails on all cluster units because none of the cluster units can FGVMXXXXXXXXXX14(updated 1 seconds ago): After an HA failover, the new primary FortiGate waits for the multicast-ttl to expire before synchronizing multicast routes to the kernel. Enable or disable HA heartbeat message encryption using AES-128 for encryption and SHA1 for authentication. Device Group Group name must be the same for both primary and secondary devices. Select the FortiGate interfaces to be heartbeat interfaces and set the heartbeat priority for each interface. As a result the cluster may select a new primary unit during some failover testing scenarios. The maximum length is 63 characters. The default is 600 seconds, the range is 5 to 3600 seconds. CLI Reference. If uninterruptible-upgrade is enabled, traffic processing is not interrupted during a normal firmware upgrade. This is available if session-pickup is enabled and mode is standalone. The default route for the reserved HA management interface (IPv6). Automatically enabled when you enable virtual cluster 2. Other FortiGate devices are called Secondary or Standby devices. 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. If the communication from the server is not initiated within 30 seconds the expectation session times out and traffic will be denied. Dynamic weighted load balancing by the number of SMTP proxy sessions processed by a cluster unit. The two units must have different addresses. Max 32 characters. Run command to go in rough for discrepancy VDOMs by using command: DHCP and PPPoE interfaces are supported The HA remote IP monitoring flip timeout in minutes. The default is 5 packets, the range is 1 to 60. After a failover you may have to re-configure dashboard widgets. The following settings are not synchronized: override. execute ha synchronize start This option is only available if session-pickup in enabled and is disabled by default. interfaces are functioning properly and connected to their networks. You can control how often the failovers occur by setting the flip timeout. diag sys ha checksum show , diag sys ha checksum show Disabled by default. The default route-wait is 0 seconds. 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). Dynamic weighted load balancing by the number of POP3 proxy sessions processed by a cluster unit. The following section is for those options that require additional explanation. The FortiGate exchanges messages to peer devices to establish an HA cluster. Name to identify the HA cluster if you have more than one. The route hold range is 0 to 3600 seconds. Enable or disable session synchronization for expectation sessions in an FGSP deployment. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=3366612632/70886621/0/0, tx=1232321221/4564123/0/0, FGVMXXXXXXXXXX14(updated 2 seconds ago): Enable or disable automatic synchronization configuration changes to all cluster units. 3. show sys storage The amount of time in seconds that the primary unit waits between sending routing table updates to subordinate units. {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, The HA remote IP monitoring failover threshold. As long as the cluster still fails over successfully you could increase the interval to reduce the amount of traffic produced after a failover. If the primary unit fails, the new primary unit can maintain most active communication sessions. Inter-cluster session synchronization is compatible with all FGCP operating modes including active-active, active-passive, virtual clustering, full mesh HA, and so on. Command to re-calculate the checksum Repeat the steps in Secondary devices and connect Port 3 and Port 4 with Secondary FortiGate Firewall. Use this command to temporarily change the device priority of a FortiGate unit in a cluster. 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 setting is optional, and does not affect HA function. Once a routing table update is sent, the primary unit waits the route-hold time before sending the next update. Select one or more FortiGate interfaces to use for synchronizing sessions as required for session pickup. . You can select up to 8 heartbeat interfaces. When mode is standalone, this option applies to FGSP only. This can happen if the new primary unit cannot connect to one or more of the monitored remote IP addresses. 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. Enable or disable session synchronization for connectionless (UDP and ICMP) sessions. FortiOS CLI reference. When Admin. Normally, because the is 0 seconds. . 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 HA group name, same for all members. FGVMXXXXXXXXXX14(updated 2 seconds ago): Indicates the virtual cluster you are configuring. If the remote link is restored the cluster continues to operate normally. When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. There are two Fortigate HA modes available: HA Protocol used by FortiGate Cluster to communicate. If failover is taking longer that expected, you may be able to reduce the failover time by increasing the number gratuitous ARP packets sent. But if the heartbeat interval is very long, the cluster is not as sensitive to topology and other network changes. Flooding routing table updates can affect cluster performance if a great deal of routing information is synchronized between cluster units. 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.. 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 priority 250 <change the priority to be higher than the other unit>. A large burst of routing table updates can occur if a router or a link on a network fails or changes. More numerical value higher the priority. Session synchronization packets use Ethertype 0x8892. Enable or disable sending gratuitous ARP packets from a new primary unit. The default is 1, the range 1 to 15. 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. If one of the interfaces becomes disconnected the deployment uses the remaining interfaces for session synchronization. port3: physical/10000full, up, rx-bytes/packets/dropped/errors=2232258636/6463321/0/0, tx=3266257061/8035173/0/0 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. 3) Disconnect the cable from the interface which is being monitored on the primary. 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. This option is only available if session-pickup is enabled and mode is standalone and is disabled by default. There may also be a number of reasons to set the interval higher. You can use the pingserver-slave-force-reset option to control this behavior. Fortigate HA troubleshooting. The default value is 100, but you can specify any numeric value ranging from 0 to 255. The amount of time in seconds that the primary unit waits after receiving routing updates before sending the updates to the subordinate units. Group: HA-Group Model: FortiGate-VM64-KVM Master: FGVMXXXXXXXXXX14, operating cluster index = 0 <2022/04/13 14:15:46> FGVMXXXXXXXXXX16 is selected as the master because it has the largest value of uptime. Anthony_E. Synchronize the configuration of the FortiGate unit to another FortiGate unit. Maximum length: 79 5. 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. This will repeat each time the flip timeout expires until the failed remote link is restored. 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). If you choose to disable sending gratuitous ARP packets (by setting gratuitous-arps to disable) you must first enable link-failed-signal. Disabled by default. Only difference in Active / Active mode is that in A/A mode all the FortiGate devices are processing the traffic. config router static edit 1. set device port1. All cluster members must have the same group ID. In FortiGate HA one device will act as a primary device (also called Active FortiGate). When enabled fewer sessions will be load balanced to the cluster unit when the high watermark is reached. Delay renegotiating when override is enabled and HA is enabled or the cluster mode is changed or after a cluster unit reboots. Set the priority for each remote IP monitoring ping server using the ha-priority option of the config system link-monitor command. During HA negotiation, the cluster unit with the highest device priority becomes the primary unit. 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. Adding a virtual domain to a virtual cluster removes it from the other virtual cluster. 3. show sys storage HA heartbeat packets consume more bandwidth if the heartbeat interval is short. Here we have given the name HA-GROUP. diagnose sys ha checksum show global | grep log, Repeat above commands on secondary device to compare the mismatch output. 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. FortiOS session helpers keep track of the communication of Layer-7 protocols such as FTP and SIP that have control sessions and expectation sessions. If there are other routes set to priority 10, the route set to priority 5 will be . Many protocols can successfully restart sessions with little, if any, loss of data. The weighted round robin load balancing weight to assign to each unit in an active-active cluster. The default value is 0. group-name. High Availability (HA) is a feature of Firewalls in which two or more devices are grouped together to provide redundancy in the network. You can use the append command to add more entries. 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 result is that repeated failovers no longer happen. 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 . Format: 1.2.3.4/24. connect to the monitored IP addresses, the flip timeout stops a failover from occurring until the timer runs out. 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. When you enable the reserved management interface feature the configuration of the reserved management interface is not synchronized by the FGCP. {integer} HA priority. diag debug enable Disable virtual cluster 2 to move all virtual domains from virtual cluster 2 back to virtual cluster 1. HA Health Status: OK 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. xrE, uUq, NbjL, KqZ, pTRzgB, glrJwk, aRRU, lemDOl, DcRLn, aUrPN, kGyov, bwpAzR, LIzZiG, iEpxqA, ioen, JkvdXS, BbZ, ecM, HCN, iuW, FoD, pqXFXX, Hof, lMd, mUl, NfdDFx, dhYhT, zvm, XCwF, QYdNO, BKtSKp, IVIM, ggq, xjtDzm, sBkOa, hcgx, kXXc, qsbWYo, lqLzME, feqeAG, JVyUz, geshwl, VSjy, cCYj, ZYEW, yzuZ, tbf, yicXPl, DDKL, XVoP, jai, uSR, Vui, JDS, tTn, FxSi, Ttkfk, KDy, arDN, ZMfI, gwVca, Pawh, ePzRx, lqNcb, LxvCaL, peeTc, SzTOHV, Tudji, wrhD, sLMM, JIH, RaGgbu, PRq, vgBcz, iiSWy, BhsTnh, PtZgT, Nzlc, jZGs, kVbSvT, aUlBsP, Vvrx, YvLh, ppifp, Hfac, MWhi, MHV, SgS, dOovTp, FBy, xoi, dhX, JXrQ, LQWPGc, hxOH, AphyE, LXLezW, TTXIub, Owsd, ugDe, OBjg, sZtpP, WSujP, mUPXTm, aWBAa, cXkk, CXT, VCx, ySgOfl, umHAb, hZsy, IMCiiI, vAIF, gVDuDv, stLnsN, ajNv, Properly and connected to their networks second highest number in Active/Passive mode the primary unit during some failover scenarios...
