Which parameters are set to the same value when a pair of BIGIP devices are synchronized.

Hostnames are unique identifiers for each BIG-IP system and are not synchronized to be the same between devices.

System clocks are typically synchronized using NTP, not through the BIG-IP's configuration synchronization process.

Profile definitions, such as HTTP profiles, SSL profiles, and TCP profiles, are crucial configuration objects that dictate how the BIG-IP processes traffic. During synchronization, these definitions are shared between the devices to ensure that both units have an identical understanding of how to handle application traffic, maintaining consistent behavior during a failover event.

VLAN failsafe settings are part of the high-availability configuration and can have device-specific values or roles, rather than being identical across devices through synchronization.

MAC masquerade addresses are unique for each traffic group on a device and are not synchronized to be identical across individual BIG-IP units.
