Configuration Guidelines for Active/Passive HA
To set up an active (PeerA) passive (PeerB) pair in
HA, you must configure some options identically on both firewalls
and some independently (non-matching) on each firewall. These HA
settings are not synchronized between the firewalls. For details
on what is/is not synchronized, see Reference: HA Synchronization.
The following checklist details the settings that you must configure
identically on both firewalls:
- You must enable HA on both firewalls.
- You must configure the same Group ID value on both firewalls. The firewall uses the Group ID value to create a virtual MAC address for all the configured interfaces. See Floating IP Address and Virtual MAC Address for information about virtual MAC addresses. When a new active firewall takes over, it sends Gratuitous ARP messages from each of its connected interfaces to inform the connected Layer 2 switches of the virtual MAC address’ new location.
- If you are using in-band ports as HA links, you must set the interfaces for the HA1 and HA2 links to type HA.
- Set the HA Mode to Active Passive on both firewalls.
- If required, enable preemption on both firewalls. The device priority value, however, must not be identical.
- If required, configure encryption on the HA1 link (for communication between the HA peers) on both firewalls.
- Based on the combination of HA1 and HA1 Backup ports you are using, use the following recommendations to decide whether you should enable heartbeat backup:HA functionality (HA1 and HA1 backup) is not supported on the management interface if it's configured for DHCP addressing (IP Type set to DHCP Client). The exceptions are AWS and Azure, where the management interface is configured as DHCP Client and it supports HA1 and HA1 Backup links.
- HA1: Dedicated HA1 portHA1 Backup: Dedicated HA1 portRecommendation: Enable Heartbeat Backup
- HA1: Dedicated HA1 portHA1 Backup: In-band portRecommendation: Enable Heartbeat Backup
- HA1: Dedicated HA1 portHA1 Backup: Management portRecommendation: Do not enable Heartbeat Backup
- HA1: In-band portHA1 Backup: In-band portRecommendation: Enable Heartbeat Backup
- HA1: Management portHA1 Backup: In-band portRecommendation: Do not enable Heartbeat Backup
The following table lists the HA settings that you must configure
independently on each firewall. See Reference: HA Synchronization for more
information about other configuration settings are not automatically
synchronized between peers.
Independent Configuration Settings | PeerA | PeerB |
---|---|---|
Control Link | IP address of the HA1 link configured on
this firewall (PeerA). | IP address of the HA1 link configured on
this firewall (PeerB). |
For firewalls without dedicated
HA ports, use the management port IP address for the control link. | ||
Data Link The data link information
is synchronized between the firewalls after HA is enabled and the control
link is established between the firewalls. | By default, the HA2 link uses Ethernet/Layer
2. If using a Layer 3 connection, configure the IP address
for the data link on this firewall (PeerA). | By default, the HA2 link uses Ethernet/Layer
2. If using a Layer 3 connection, configure the IP address
for the data link on this firewall (PeerB). |
Device Priority (required, if preemption
is enabled) | The firewall you plan to make active must
have a lower numerical value than its peer. So, if Peer A is to function
as the active firewall, keep the default value of 100 and increment
the value on PeerB. If the firewalls have the same device
priority value, they use the MAC address of their HA1 as the tie-breaker. | If PeerB is passive, set the device priority
value to a number larger than the setting on PeerA. For example,
set the value to 110. |
Link Monitoring—Monitor one or more physical
interfaces that handle vital traffic on this firewall and define the
failure condition. | Select the physical interfaces on the firewall
that you would like to monitor and define the failure condition (all
or any) to trigger a failover. | Pick a similar set of physical interfaces
that you would like to monitor on this firewall and define the failure
condition (all or any) to trigger a failover. |
Path Monitoring—Monitor one or more destination
IP addresses that the firewall can use ICMP pings to ascertain responsiveness. | Define the failure condition (all or any),
ping interval and the ping count. This is particularly useful for
monitoring the availability of other interconnected networking devices.
For example, monitor the availability of a router that connects
to a server, connectivity to the server itself, or some other vital
device that is in the flow of traffic. Make sure that the
node/device that you are monitoring is not likely to be unresponsive,
especially when it comes under load, as this could cause a a path
monitoring failure and trigger a failover. | Pick a similar set of devices or destination
IP addresses that can be monitored for determining the failover
trigger for PeerB. Define the failure condition (all or any), ping
interval and the ping count. |
