Palo Alto – What Settings Don’t Sync in Active/Passive HA?


 

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.

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.
