High Availability Status

The High Availability Status section on the DEVICE | High Availability > Status page displays the following information:

• Status – Indicates the High Availability status of the current firewall. The possible values are:
  • Primary Active – Indicates that the current appliance is the Primary unit in the ACTIVE state.
  • Primary Standby – Indicates that the current appliance is the Primary unit in the STANDBY state.
  • Primary Disabled – Indicates that the current appliance is the Primary unit, but High Availability has not been enabled.
  • Primary not in a steady state – Indicates that the current appliance is the Primary unit, HA is enabled, and the appliance is neither in the ACTIVE nor the STANDBY state.

• Primary State - Indicates the current state of the Primary appliance as a member of an HA Pair. The Primary State field is displayed on both the Primary and the Secondary appliances. The possible values are:

  • ACTIVE – Indicates that the Primary unit is handling all the network traffic except management/monitoring/licensing traffic destined to the standby unit.

  • STANDBY – Indicates that the Primary unit is passive and is ready to take over on a failover.

  • ELECTION – Indicates that the Primary and Secondary units are negotiating which should be the ACTIVE unit.

  • SYNC – Indicates that the Primary unit is synchronizing settings or firmware to the Secondary.

  • ERROR – Indicates that the Primary unit has reached an error condition.

  • REBOOT – Indicates that the Primary unit is rebooting.

  • NONE – When viewed on the Primary unit, NONE indicates that HA is not enabled on the Primary. When viewed on the Secondary unit, NONE indicates that the Secondary unit is not receiving heartbeats from the Primary unit.

• Secondary State - Indicates the current state of the Secondary appliance as a member of an HA Pair. The Secondary State field is displayed on both the Primary and the Secondary appliances. The possible values are:

  • ACTIVE – Indicates that the Secondary unit is handling all the network traffic except management/monitoring/licensing traffic destined to the standby unit.

  • STANDBY – Indicates that the Secondary unit is passive and is ready to take over on a failover.

  • ELECTION – Indicates that the Secondary and Primary units are negotiating which should be the ACTIVE unit.

  • SYNC – Indicates that the Secondary unit is synchronizing settings or firmware with the Primary.

  • ERROR – Indicates that the Secondary unit has reached an error condition.

  • REBOOT – Indicates that the Secondary unit is rebooting.

  • NONE – When viewed on the Secondary unit, NONE indicates that HA is not enabled on the Secondary. When viewed on the Primary unit, NONE indicates that the Primary unit is not receiving heartbeats from the Secondary unit.

• Active Up Time - Indicates how long the current Active firewall has been Active, since it last became Active. If the unit is not part of an HA pair, this line displays High Availability Disabled.

• Found Peer - Indicates if the Primary unit has discovered the Secondary unit. Possible values are Yes and No.

• Settings Synchronized - Indicates if HA settings are synchronized between the Primary and Secondary units. Possible values are Yes and No.

• Stateful HA Synchronized - Indicates if stateful synchronization settings are synchronized between the Primary and Secondary units. Possible values are Yes and No.
