What are two reasons why time synchronization between FortiGate and its managed FortiSwitch is critical...

Time synchronization between FortiGate and its managed FortiSwitch devices is essential for several reasons:

A. FortiSwitch does not retain its time after a reboot, which gets reset after each reboot.This characteristic of FortiSwitch underlines the importance of time synchronization with FortiGate. Since FortiSwitch loses its time settings upon reboot, synchronizing with FortiGate ensures that its system clock is accurate, which is vital for logging, troubleshooting, and security timestamping.

C. FortiSwitch cannot complete the DTLS handshake used in the CAPWAP tunnel.Accurate time synchronization is crucial for security protocols such as DTLS, which rely on timestamped certificates for establishing a secure connection. If the time on FortiSwitch is not synchronized with FortiGate, the DTLS handshake used in the CAPWAP tunnel for secure communication may fail due to time discrepancies, impacting the management and operation of the switch.
