Why is it critical to maintain NTP synchronization between FortiGate and FortiSwitch when FortiLink is configured?
FortiGate and FortiSwitchmust share synchronized timewhen operating in FortiLink mode.
Documented reasons in FortiOS:
Accurate time synchronization is required for logs, authentication events, and fabric correlations.
Why it's critical:
802.1X EAP and RADIUS timestamp validation
NAC policy enforcement timestamps
Certificate validation
Log correlation in Security Fabric / FortiAnalyzer
Incorrect options:
A: Firmware synchronization does NOT require NTP.
B: Switch-to-switch communication does not depend on NTP.
D: Standalone mode is unrelated to time sync.
