Enter the Cluster Node owner/standby rankings for each Virtual Group. Layer-2 Bridged interfaces are not supported in a cluster configuration. Contact an Account Representative for further details. SonicWall High Availability Security Appliance - TZ270 The latest SonicWall TZ series, are the first desktop form factor next generation firewalls (NGFW) with 10 or 5 Gigabit Ethernet interfaces. This section contains the following subsections: How Does Stateful Synchronization Work? If you find it cheaper let us know. Active - Describes the operative condition of a hardware unit. The connected interfaces must be the same number on both appliances, and must initially appear as unused, unassigned interfaces in the Network > Interfaces page. One SonicWall SuperMassive is configured as the Primary unit, and an identical Security Appliance is configured as the Secondary unit. Connecting the Active/Active DPI Interfaces for Active/Active DPI. Tata Consultancy Services. Swaytronic -Stecksystem. This is in contrast to traditional IP routing in which each packet in a flow may technically be forwarded along a different path as long as it arrives at its intended destination the intervening routers do not have to see every packet. Developed and manage the Cloud infrastructure, Azure, AWS, and Gsuite and built site-to-site connectivity between on-premises and cloud-based architectures. Stateful HA Synchronized - Indicates if stateful synchronization settings are synchronized between the Primary and Secondary units. Power down all the units except the unit that is to be designated as the Primary unit. HA Data InterfaceCan be a 1GB or 10GB interface. SYNC Indicates that the Primary unit is synchronizing settings or firmware to the Secondary. The Primary and Secondary IP addresses configured on the High Availability > Monitoring page can be configured on LAN or WAN interfaces, and are used for multiple purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in to each unit independently for management purposes. Virtual MAC for reduced convergence time after failover The Virtual MAC address setting allows the HA Pair to share the same MAC address, which dramatically reduces convergence time following a failover. Login to your MySonicWALL account at https://www.mysonicwall.com. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. From a routing perspective, all Cluster Nodes appear as parallel routers, each with the virtual IP address of the Cluster Node's interface. This document describes the configuration options for all High Availability settings, whether they pertain to Active/Active Clustering or only to the HA pair. Dubai, United Arab Emirates. Login to the Primary unit in Cluster Node 1, leaving other units down. There are two types of failover that can occur when Active/Active Clustering is enabled: High Availability failover Within an HA pair, the Secondary unit takes over for the Primary. Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. After enabling Active/Active DPI, the connected interface will have a Zone assignment of HA Data-Link. The failing service is isolated as early as possible, and the failover mechanism repairs it automatically. Active/Standby and Active/Active DPI HA Prerequisites. Optionally, you can manually configure the Virtual MAC address on the High Availability > Monitoring page. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. Both appliances must be the same SonicWALL model. For example, say we have a deployment in which Virtual Group 1 is owned by Cluster Node 1 and Virtual Group 2 is owned by Cluster Node 2. 7. When the Primary SonicWALL restarts after a failure, it is accessible using the third IP address created during configuration. This ensures that the Secondary appliance is always ready to transition to the Active state without dropping any connections. The Primary and Secondary SonicWALL devices are currently only capable of performing Active/Standby High Availability or Active/Active DPI complete Active/Active high availability is not supported at present. Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. KE Live App cloud Infrastructure designed. The Virtual MAC setting is available even if Stateful High Availability is not licensed. 8. Active/Active failover If all the units in the owner node for a Virtual Group encounter a fault condition, then the standby node for the Virtual Group takes over the Virtual Group ownership. The latter is the High Availability > Monitoring page. We prefer . Primary Standby Indicates that this appliance is in the standby state. 5. This section describes the physical connections needed for Active/Active Clustering and Active/Active DPI. The SE role is for technicians who have mastered first-tier support to the point . Note Because all Cluster Nodes shares the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). This field is for validation purposes and should be left unchanged. 1 x console - micro-USB Networking Performance Firewall throughput: 5 Gbps Threat prevention throughput: 2.5 Gbps Application throughput: 3 Gbps IPS throughput: 3 Gbps Anti-malware throughput: 2.5 Gbps TLS/SSL inspection and decryption throughput: 800 Mbps VPN throughput (IPSec): 2.1 Gbps Connection rate: 25000 connections per second Capacity HA requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Secondary SonicWALL. Both appliances must be the same Dell SonicWALL model. The synchronization traffic is throttled to ensure that it does not interfere with regular network traffic. This chapter contains the following main sections: The following sections provide overviews of SonicWALLs implementation of HA: How Does Stateful Synchronization Work? Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. On the My Products page, under Registered Products, scroll down to find the appliance to which you want to copy the license keyset. Currently, a maximum of four Virtual Groups are supported. SonicWALL SuperMassive requires the following interface link speeds for each designated HA interface: HA Control Interface Must be a 1GB interface: X6 to X21 interfaces at 1 Gbps - Full Duplex HA Data Interface Must be a 10GB interface: X0 to X5 interfaces at 10 Gbps - Full Duplex Active/Active DPI Interface Must be a 10GB interface: Firmware or signature updates, changes to policies, and other configuration changes cannot be synchronized to other Cluster Nodes until the HA port connection is fixed. SonicWall Support High Availability Requirements When deployed as a High Availability pair, both the active and standby firewalls must have a connection to the server or URL to download the file that contains the list of IP addresses or FQDNs.

Preform the tasks described in Active/Standby and Active/Active DPI HA Prerequisites, including registering and associating the appliances on MySonicWALL and licensing the high availability features. Update network diagram: SuperMassive network diagram. 6. The Secondary SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. The original owner will have a higher priority for a Virtual Group due to its higher ranking if all virtual IP interfaces are up and the link weight is the same between the two Cluster Nodes. Procedures are provided in this section for both of these tasks within the section High Availability > Settings. You do not need to purchase a second set of licenses for the Secondary unit in a High Availability Pair. Select Active/Active DPI on the High Availability > Settings page. Start up the other units in the Active/Standby HA pair. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. Note that the Secondary appliance of the HA pair is referred to as the HA Secondary unit on MySonicWALL. This section provides an introduction to the Stateful Synchronization feature. When physical interface monitoring is enabled, with or without logical monitoring enabled, HA failover takes precedence over Active/Active failover. This requires configuring the monitoring IP address on the standby unit. When Virtual MAC is enabled, it is always used even if Stateful Synchronization is not enabled. 2. Critical internal system processes such as NAT, VPN, and DHCP (among others) are checked in real time. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Standby unit. The HA feature has a thorough self-diagnostic mechanism for both the Primary and Secondary SonicWALL SuperMassives. 5. The self-checking mechanism is managed by software diagnostics, which check the complete system integrity of the SonicWALL device. If the Secondary has taken over for the Primary, the status indicates that the Secondary is currently Active. Active/Standby and Active/Active DPI HA Prerequisites, Registering and Associating Appliances on MySonicWALL. Zyxel USG Flex Firewall VERSION 2 10/100/1000 1xWAN 4xLAN/DMZ ports 1xUSB Device only. Note Default NAT policies will be created automatically, so there is no need to configure NAT policies for Virtual Groups in the Network > NAT Policies page. All clients and remote sites continue to use the same Virtual MAC address and IP address without interruption. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. The two appliances in each HA pair must also be associated as HA Primary and HA Secondary on MySonicWALL. Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. 10. The Primary and Secondary appliances are continuously synchronized so that the Secondary can seamlessly assume all network responsibilities if the Primary appliance fails, with no interruptions to existing network connections. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. Before you can enable Active/Active Clustering, Stateful Synchronization, and Active/Active DPI, these features must be licensed. The possible values are: Primary Active Indicates that the Primary HA appliance is in the ACTIVE state. This IP routing behavior presents problems for a firewall cluster because the set of Cluster Nodes all provide a path to the same networks. 6. Active/Active Clustering, Stateful High Availability, and Active/Active DPI licenses are included on registered firewalls. High Availability SonicWall has three kinds of High Availability detailed below. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. 4. This section provides an introduction to the Stateful Synchronization feature. After a failover to the Secondary appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. Failure to periodically communicate with the device by the active unit in the HA pair will trigger a failover to the standby unit. A PC user connects to the network, and the Primary SonicWALL SuperMassive creates a session for the user. For further information, see Registering and Associating Appliances on MySonicWALL . It is not required that the Primary and Secondary appliances have the same security services enabled. Physically connect the designated HA ports from the Primary to the Secondary HA unit. Secondary - Describes the subordinate hardware unit itself. Proven ability to create and deliver solutions tied to business growth Phone organizational development and systems/network . Note Stateful High Availability is not supported on SonicWALL TZ series appliances. 12. The series consist of a wide range of products . This greatly simplifies the failover process as only the connected switches need to update their learning tables. With Active/Active DPI enabled on a Stateful HA pair, these DPI services are processed on the standby firewall of an HA pair concurrently with the processing of firewall, NAT, and other modules on the active firewall. You can use a dedicated switch or simply use some ports on an existing switch in your internal network. If preempt mode is enabled, the Primary SonicWALL becomes the Active firewall and the Secondary firewall returns to Standby status. contactez ou appelez au 016 - 796 200 . This chapter contains the following main sections: High Availability Overview SEs (Systems Engineers) focus on project work, escalations, and mentorship for our Systems Administrators. 8. Check " Enable Stateful Synchronization ". The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. Possible values are Yes or No. SKU. The Secondary identifier is a relational designation, and is assumed by a unit when paired with a Primary unit. 5. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. The power is unplugged from the Primary appliance and it goes down. Under normal operating conditions, the Secondary unit operates in Standby mode. ), it immediately informs the Secondary appliance. The alternative Cluster Node might already be processing traffic comparable in amount to the failed unit, and could become overloaded after failover. All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. The Virtual MAC address allows the High Availability pair to share the same MAC address, which dramatically reduces convergence time following a failover. Until this ARP request propagates through the network, traffic intended for the Primary appliances MAC address can be lost. Active/Active DPI ClusteringThis mode allows for the configuration of up to four HA cluster nodes for failover and load sharing, where the nodes load balance the application of DPI security services to network traffic. Configuration changes and firmware updates are only allowed on the Master Node, which uses SVRRP to synchronize the configuration and firmware to all the nodes in the cluster. In the event of the failure of the Primary firewall, the Secondary firewall takes over to secure a reliable connection between the protected network and the Internet. The preferences can then be imported without potential conflicts after upgrading. In the event of the failure of an entire Cluster Node, the failover will be stateless. This article describes about each state briefly. In the left navigation pane, click My Products. The Primary SonicWall and Secondary SonicWall in High Availability Pair, when configured, go through different states. In addition to the two types of failover, the following feature provides protection against a single point of failure: Port Redundancy Although technically not a failover, a redundant port provides secondary by handling all the traffic if its partner has a fault. < Previous Section Next Section > When the PC user attempts to access a Web page, the Secondary appliance has all of the users session information and is able to continue the users session without interruption. Thank You. When the Active/Active Clustering configuration is applied, up to three additional Virtual Groups are created, corresponding to the additional Cluster Nodes added, but virtual IP addresses are not created for these Virtual Groups. Note Even if you first register your appliances on MySonicWALL, you must individually register both the Primary and the Secondary appliances from the SonicOS management interface while logged into the individual management IP address of each appliance. When the firewalls in the Active/Active cluster have Internet access, each appliance in the cluster must be individually registered from the SonicOS management interface while the administrator is logged into the individual management IP address of each appliance. The link is sensed at the physical layer to determine link viability. The Cluster Node that becomes the Virtual Group owner also becomes the owner of all the virtual IP addresses associated with the Virtual Group and starts using the corresponding virtual MAC addresses. Note that non-management traffic is ignored if it is sent to one of these IP addresses. Firewalls. If neither unit in the HA pair can connect to the device, the problem is assumed to be with the device and no failover will occur. In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. 5. As the Primary appliance creates and updates network connection information (VPN tunnels, active users, connection cache entries, etc. SSL VPN Clients: 100 Write a review 511.00 (613.20 inc VAT) SKU: 02-SSC-6443 Availability: 10+ In stock * Qty. When using SonicWALL Global Management System (GMS) to manage the appliances, GMS logs into the shared WAN IP address. Primary Active / Active Licensed - Indicates if the Primary appliance has a Active / Active license. When the Active unit encounters a fault condition, stateful failover occurs as the Standby firewall takes over the Active role with no interruptions to the existing network connections. The management IP address of the Secondary unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA pair). Cluster Node management and monitoring state messages are sent using SVRRP over the HA port connection. The benefits of Active/Active Clustering include the following: All the firewalls in the cluster are utilized to derive maximum throughput, Can run in conjunction with Active/Active DPI to perform concurrent processing of IPS, GAV, Anti-Spyware, and App Rules services, which are the most processor intensive, on the standby firewall in each HA pair while the active firewall performs other processing, Load sharing is supported by allowing the assignment of particular traffic flows to each node in the cluster, All nodes in the cluster provide redundancy for the other nodes, handling traffic as needed if other nodes go down, Interface redundancy provides secondary for traffic flow without requiring failover, Both Full Mesh and non-Full Mesh deployments are supported. HA Control Link Indicates the port, speed, and duplex settings of the HA link, such as HA 1000 Mbps full-duplex, when two firewalls are connected over their specified HA interfaces. The Cluster Node consists of a Stateful HA pair, in which the Secondary firewall can assume the duties of the Primary unit in case of failure. When more than two Cluster Nodes are configured in a cluster, these factors determine the Cluster Node that is best able to take ownership of the Virtual Group. Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. Cost-effectiveness High Availability is a cost-effective option for deployments that provide high availability by using redundant firewalls. . The following sections provides feature support information about Active/Active Clustering: Routing Topology and Protocol Compatibility. You can also start the process by selecting a registered unit and adding a new appliance with which to associate it. Manufacturer. The Secondary now has all of the users session information. Configure IP addresses for the desired interfaces on the Network > Interfaces page. It is an active-standby configuration where the Primary appliance handles all traffic. Note The Active/Active virtual MAC address is different from the High Availability virtual MAC address. If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Standby unit. OTP deployment consists of a number of configuration steps, including preparing the infrastructure for OTP authentication, configuring the OTP server, configuring OTP settings on the Remote Access server, and updating DirectAccess client settings. 5. Sept. 2015-Jan. 20171 Jahr 5 Monate. SonicWALL wired and wireless security solutions are deployed in 200 countries by . Login to the Primary unit, leaving other units down. If one Cluster Node goes down, causing an Active/Active failover, the redundant port on the remaining Cluster Node is put to use immediately to handle the traffic for the Virtual Group that was owned by the failed node. The diagnostics check internal system status, system process status, and network connectivity. The Virtual MAC address greatly simplifies this process by using the same MAC address for both the Primary and Secondary appliances. We will cover the unique and. Standby - Describes the passive condition of a hardware unit. In the SonicOS management interface, navigate to the Network > Interfaces page and ensure that the Zone is Unassigned for the intended Active/Active DPI Interface. That is, associate the two appliances in the HA pair for Cluster Node 1, then associate the appliances in the HA pair for Cluster Node 2, and so on for any other Cluster Nodes. When the Primary SonicWALL restarts after a failure, it is accessible using the unique IP address created on the High Availability > Monitoring page. You can use one of the following procedures to apply licenses to an appliance: Activating Licenses from the SonicOS User Interface, Copying the License Keyset from MySonicWALL, Activating Licenses from the SonicOS User Interface. For increased performance in an Active/Active cluster, enabling Active/Active DPI is recommended, as it utilizes the standby firewall in the HA pair for Deep Packet Inspection (DPI) processing. Active/Active Clustering Full-Mesh Overview, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL. It is also possible to check the status of the Secondary SonicWALL by logging into the unique LAN IP address of the Secondary SonicWALL. Failover - Describes the actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. No traffic is sent on X4 while all nodes are functioning properly. In the event of a failure in the Primary SonicWALL, you can access the management interface of the Secondary SonicWALL at the Primary SonicWALL virtual LAN IP address or at the Secondary SonicWALL LAN IP address. Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. Large enterprises can configure the solution for high availability and split mode to centrally and reliably manage large . If failure of the Primary SonicWALL occurs, the Secondary SonicWALL assumes the Primary SonicWALL LAN and WAN IP addresses. 13. 7. The Secondary State field is displayed on both the Primary and the Secondary appliances. With Active/Active DPI enabled on a Stateful HA pair, these DPI services are processed on the standby firewall of an HA pair concurrently with the processing of firewall, NAT, and other modules on the active firewall. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. The following features are not supported when Active/Active Clustering is enabled: The following features are only supported on Virtual Group 1: NOTE: IP Helper enhancements are available in SonicOS 6.0.5. Expanded licenses must be purchased on MySonicWALL or from a Dell SonicWALL reseller. Active/Active DPI is not supported on the following Dell SonicWALL models: High Availability requires additional physical connections among the affected SonicWALL appliances. SonicWall Firewall high availability overview 2,538 views Jun 29, 2021 This is a quick overview video about SonicWall firewall in stateful High availability. Active Up Time - Indicates how long the current Active firewall has been Active, since it last became Active. Active/Active Clustering can be enabled with or without enabling Active/Active DPI, just as Active/Active DPI can be enabled with or without enabling Active/Active Clustering. The SonicWall Network Security Appliance (NSA) series combines the patented SonicWall Reassembly Free Deep Packet Inspection (RFDPI) engine with a powerful and massively scalable multi-core architecture to deliver intrusion prevention, gateway anti-virus, gateway anti-spyware, and application intelligence and control for businesses of all sizes. One firewall is configured as the Primary unit, and an identical firewall is configured as the Secondary unit. When incremental synchronization fails, a complete synchronization is automatically attempted. Load Sharing and Multiple Gateway Support. A packet arriving on a Virtual Group will leave the firewall on the same Virtual Group. In a typical configuration, each Cluster Node owns a Virtual Group, and therefore processes traffic corresponding to one Virtual Group. The Virtual MAC address allows the High Availability pair to share the same MAC address, which dramatically reduces convergence time following a failover. Routers make no attempt to direct return traffic to the originating router. No routing updates are necessary for downstream or upstream network devices. Leading an infrastructure team and ensuring the availability, performance, scalability, redundancy, and security objectives of client's infrastructure. The Primary appliance synchronizes with the Secondary appliance. The types of administrative actions that are allowed differ based on the state of the firewall in the cluster. By default, this Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. The Active identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. SonicWall NSSP 10700 High Availability. For communication between Cluster Nodes, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. 3. When deployed as a High Availability pair, both the active and standby firewalls must have a connection to the server or URL to download the file that contains the list of IP addresses or FQDNs. After the appliances are associated as an HA pair, they can share licenses. The Standby identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. This interface will take over transferring data between the two units during Active/Active DPI processing if the first Active/Active DPI Interface has a fault.
