HA system requirements

  • Two identical appliances (the same hardware model and same firmware version).
  • By default, you use MGMT2 port to connect the HA appliances directly or through a Layer 2 switch. The HA port can be changed but be aware of the settings on the System > Network > Interface page before changing from default.
  • Heartbeat and synchronization traffic between cluster nodes occur over the physical network ports you specify. If switches are used to connect heartbeat interfaces between nodes, the heartbeat interfaces must be reachable by Layer 2 multicast. HA traffic uses multicast UDP on port numbers 6065 (heartbeat) and 6056 (synchronization). The HA multicast IP address is 239.0.0.1; it is hard-coded, and cannot be configured.
