Which parameters are set to the same value when a pair of BIG-IP devices are synchronized?

Host names are unique identifiers for each BIG-IP device and are not synchronized, as each device needs its distinct identity.

System clocks are usually synchronized via NTP independently and are not part of the BIG-IP's configuration synchronization mechanism itself.

Profile definitions, which include settings for how traffic is processed (e.g., HTTP profiles, TCP profiles), are critical for application delivery and are synchronized between BIG-IP devices to ensure consistent behavior and policies across the HA pair.

VLAN failsafe settings are specific to the network configuration and behavior of individual devices and are not typically synchronized.

MAC masquerade addresses are associated with floating self-IPs and are configured uniquely for specific interfaces or VLANs, rather than being a globally synchronized parameter.
