    What Settings Don’t Sync in Active/Active HA?

    You must configure the following settings on each firewall in an HA pair in an active/active deployment. These settings do not sync from one peer to another.
    Configuration Item
    What Doesn’t Sync in Active/Active?
    Management Interface Settings
    You must configure all management settings individually on each firewall, including:
    • Device
      Setup
      Management
      General Settings
      —Hostname, Domain, Login Banner, SSL/TLS Service Profile (and associated certificates), Time Zone, Locale, Date, Time, Latitude, Longitude.
    • Device
      Setup
      Management
      Management Interface Settings
      —IP Address, Netmask, Default Gateway, IPv6 Address/Prefix Length, Default IPv6 Gateway, Speed, MTU, and Services (HTTP, HTTP OCSP, HTTPS, Telnet, SSH, Ping, SNMP, User-ID, User-ID Syslog Listener-SSL, User-ID Syslog Listener-UDP)
    Multi-vsys Capability
    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-4000 Series, PA-5000 Series, and PA-7000 Series firewalls.
    You must also enable
    Multi Virtual System Capability
     on each firewall (
    Device
    Setup
    Management
    General Settings
    ).
    Panorama Settings
    Set the following Panorama settings on each firewall (

    Software Updates
    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.
    • Device
      Software
    GlobalProtect Agent Package
    With GlobalProtect client 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.
    • Device
      GlobalProtect Client
    Content Updates
    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.

    Ethernet Interface IP Addresses
    All Ethernet interface configuration settings sync except for the IP address (
    Network

    Ethernet
    ).
    Loopback Interface IP Addresses
    All Loopback interface configuration settings sync except for the IP address (
    Network

    Loopback
    ).
    Tunnel Interface IP Addresses
    All Tunnel interface configuration settings sync except for the IP address (
    Network
    Interface
    Tunnel
    ).
    LACP System Priority
    Each peer must have a unique LACP System ID in an active/active deployment (
    Network
    Interface
    Ethernet
    Add Aggregate Group
    System Priority
    ).
    VLAN Interface IP Address
    All VLAN interface configuration settings sync except for the IP address (
    Network
    Interface
    VLAN
    ).
    Virtual Routers
    Virtual router configuration synchronizes only if you have enabled VR Sync (
    Device
    High Availability
    Active/Active Config
    Packet Forwarding
    ). Whether or not to do this depends on your network design, including whether you have asymmetric routing.
    IPSec Tunnels
    IPSec tunnel configuration synchronization is dependent on whether you have configured the Virtual Addresses to use Floating IP addresses (
    Device
    High Availability
    Active/Active Config
    Virtual Address
    ). If you have configured a floating IP address, these settings sync automatically. Otherwise, you must configure these settings independently on each peer.
    GlobalProtect Portal Configuration
    GlobalProtect portal configuration synchronization is dependent on whether you have configured the Virtual Addresses to use Floating IP addresses (
    Network
    GlobalProtect
    Portals
    ). If you have configured a floating IP address, the GlobalProtect portal configuration settings sync automatically. Otherwise, you must configure the portal settings independently on each peer.
    GlobalProtect Gateway Configuration
    GlobalProtect gateway configuration synchronization is dependent on whether you have configured the Virtual Addresses to use Floating IP addresses (
    Network
    GlobalProtect
    Gateways
    ). If you have configured a floating IP address, the GlobalProtect gateway configuration settings sync automatically. Otherwise, you must configure the gateway settings independently on each peer.
    QoS
    QoS configuration synchronizes only if you have enabled
    QoS Sync
     (
    Device
    High Availability
    Active/Active Config
    Packet Forwarding
    ). You might choose not to sync QoS setting if, for example, you have different bandwidth on each link or different latency through your service providers.
    LLDP
    No LLDP state or individual firewall data is synchronized in an active/active configuration (
    Network
    Network Profiles
    LLDP
    ).
    BFD
    No BFD configuration or BFD session data is synchronized in an active/active configuration (
    Network
    Network Profiles
    BFD Profile
    ).
    IKE Gateways
    IKE gateway configuration synchronization is dependent on whether you have configured the Virtual Addresses to use floating IP addresses (
    Network
    IKE Gateways
    ). If you have configured a floating IP address, the IKE gateway configuration settings sync automatically. Otherwise, you must configure the IKE gateway settings independently on each peer.
    Master Key
    The master key must be identical on each firewall in the HA pair, but you must manually enter it on each firewall (
    Device
    Master Key and Diagnostics
    ).
    Before changing the master key, you must disable config sync on both peers (
    Device
    High Availability
    General
    Setup
     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.
    HA settings
    • Device
      High Availability
    • (The exception is
      Device
      High Availability

      Virtual Addresses

    Certificates for Device Management and Syslog Communication over SSL only

    Certificate Management
    Certificates
    Certificates used for device management or for syslog communication over SSL don’t synchronize with an HA peer.

    Certificate Management
    Certificate Profile
    SSL/TLS Service Profile for Device Management only
    Device
    Certificate Management
    SSL/TLS Service Profile
    SSL/TLS Service Profile for Device Management doesn’t synchronize with an HA peer.
