You must configure the auxiliary device before you can configure the primary device
and enable HA.
-
Go to .
-
Specify the initial HA device state.
Option | Description |
---|
Initial HA device state |
Primary |
-
Specify the HA configuration mode for the cluster.
Option | Description |
---|
Active–Active |
The primary device receives all network traffic and load-balances
the traffic using the auxiliary. Both the primary and auxiliary devices
process traffic. The auxiliary takes over if a power, hardware, or
software failure occurs on the primary. |
Active–Passive |
The primary device processes all network traffic and the auxiliary
remains in stand-by mode. The auxiliary becomes active and takes over
only in case of a power, hardware, or software failure on the primary.

-
Type and confirm a passphrase.
Note The devices in the cluster must have the same passphrase.
-
Select a dedicated HA link.
Option | Description |
---|
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.
-
Specify the settings.
Option | Description |
---|
Peer HA link IPv4 |
IP address configured on the HA link port of the auxiliary device.
|
Peer administration port |
Port that is used for administration purposes on the auxiliary
device. |
Peer administration IP |
IP address that provides access to the administration console of
the auxiliary device. |
-
Select ports to be monitored for HA status.
If any monitored port goes down, the device will leave the cluster and
failover will occur.
Note This feature is not supported in virtual security devices.
-
Click Enable HA.
The primary device pushes its configuration to the auxiliary.
When HA is active, the devices will synchronize automatically. To force the device to push
configuration updates to the auxiliary, click Sync auxiliary.
If you have configured the device for Active–Passive mode, you can force the
auxiliary to take over as the primary device by clicking Put on standby.
