Configure active-active HA using interactive mode

How to use interactive mode to configure an active-active HA cluster.

To configure active-active HA using interactive mode, do as follows:

  1. Sign in to the firewall that will be the auxiliary device.
  2. Go to System services > High availability.
  3. Specify the initial HA device state.
    OptionDescription
    Initial device role Auxiliary
  4. Select Interactive mode.
  5. A passphrase is generated automatically. You can also change it manually.
    Note The devices in the cluster must have the same passphrase.
  6. Select a dedicated HA link.
    OptionDescription
    Dedicated HA link The link to be monitored. Peers in an HA cluster continuously monitor the dedicated HA link and the interfaces configured to be monitored.
    Note The peer device must use the same HA link. Specify this port as the HA link port on the peer. For example, if you choose port E on the primary device, you must also choose port E on the auxiliary device.
    Note The IP address of the HA link for the peer device must be on the same subnet.
  7. Click Save.
  8. Sign in to the firewall that will be the Primary device.
  9. Go to System services > High availability.
  10. Specify the initial HA device state.
    OptionDescription
    Initial device role Primary (active-active)
  11. Select Interactive mode.
  12. Assign a cluster ID, if required.

    A cluster is a pair of devices operating in HA. Devices in the same cluster must share the same cluster ID.

    If you have multiple HA clusters, assign a different ID to each cluster.

  13. A passphrase is generated automatically. You can also change it manually.
    Note The devices in the cluster must have the same passphrase.
  14. Select a dedicated HA link.
    OptionDescription
    Dedicated HA link The link to be monitored. Peers in an HA cluster continuously monitor the dedicated HA link and the interfaces configured to be monitored.
    Note The peer device must use the same HA link. Specify this port as the HA link port on the peer. For example, if you choose port E on the primary device, you must also choose port E on the auxiliary device.
    Note The IP address of the HA link for the peer device must be on the same subnet.
  15. Select ports to be monitored for HA status.
    If any monitored port goes down, the device leaves the cluster, and a failover takes place.
    Note This feature isn't supported in virtual security devices.
  16. Specify Peer administration settings.
    OptionDescription
    Interface Port that is used for administration purposes on the auxiliary device.
    IPv4 address IPv4 address that provides access to the web admin console of the auxiliary device.
    IPv6 address IPv6 address that provides access to the web admin console of the auxiliary device.
    Note You can't enable HA if you turned on STP on a bridge interface.
    Note To access the peer administration IP, you must use a machine within the same LAN network, and the access must not be established through the primary device.
  17. Specify the keepalive request interval in milliseconds. You can use a value from 250 to 500. Default is 250.
  18. Specify the number of keepalive attempts. You can use a value from 16 to 24. Default is 16.
    Note You can't set the keepalive interval and keepalive attempts for devices in standalone and fault modes.
  19. Optional Select the checkbox if you want to use the hypervisor-assigned MAC address. This option is available only with virtual appliances.

    This removes the need to turn on promiscuous mode on the vSwitch.

  20. Specify if the system should fallback to the primary device when it recovers.

    In the event of a failover, traffic is routed through the auxiliary. If you want this to automatically move back to the primary device when it recovers, select this option.

    Note If the device is in standalone or fault mode, this functionality isn't supported.
  21. Click Initiate HA.
    The primary device pushes its configuration to the auxiliary.
