You must configure the following settings on each firewall in an HA pair in an active/passive deployment. These settings do not sync from one peer to another.
What Doesn’t Sync in Active/Passive?
Management Interface Settings
All management configuration settings must be configured individually on each firewall, including:
· DeviceSetupManagementGeneral Settings—Hostname, Domain, Login Banner, SSL/TLS Service Profile, Time Zone, Locale, Date, Time, Latitude, Longitude.
The configuration for the associated SSL/TLS Service profile (DeviceCertificate ManagementSSL/TLS Service Profile and the associated certificates (DeviceCertificate ManagementCertificates) is synchronized. It is just the setting of which SSL/TLS Service Profile to use on the Management interface that does not sync.
You must activate the Virtual Systems license on each firewall in the pair to increase the number of virtual systems beyond the base number provided by default on PA-3000 Series, PA-3200 Series, PA-5000 Series, PA-5200 Series, and PA-7000 Series firewalls.
You must also enable Multi Virtual System Capability on each firewall (DeviceSetupManagementGeneral Settings).
Administrator Authentication Settings
You must define the authentication profile and certificate profile for administrative access to the firewall locally on each firewall (DeviceSetupManagementAuthentication).
Set the following Panorama settings on each firewall (DeviceSetupManagementPanorama Settings).

With software updates, you can either download and install them separately on each firewall, or download them on one peer and sync the update to the other peer. You must install the update on each peer (DeviceSoftware).
GlobalProtect Agent Package
With GlobalProtect app updates, you can either download and install them separately on each firewall, or download them to one peer and sync the update to the other peer. You must activate separately on each peer (DeviceGlobalProtect Client).
With content updates, you can either download and install them separately on each firewall, or download them on one peer and sync the update to the other peer. You must install the update on each peer (DeviceDynamic Updates).
The master key must be identical on each firewall in the HA pair, but you must manually enter it on each firewall (DeviceMaster Key and Diagnostics).
Before changing the master key, you must disable config sync on both peers (DeviceHigh AvailabilityGeneralSetup and clear the Enable Config Sync check box) and then re-enable it after you change the keys.
Reports, logs, and Dashboard Settings
Log data, reports, and Dashboard data and settings (column display, widgets) are not synced between peers. Report configuration settings, however, are synced.
