The FMC is not a full-blown NTP server.Thus, it is highly recommended that FMC and FCM use the same NTP server. Currently, there is no possibility to synchronize NTP on FTD with Firepower Management Center (FMC), even if you choose that option, NTP on FTD is synchronized with MIO.The NTP on the logical devices (ASA or FTD) is synchronized with the MIO.To configure NTP on a Firepower 41xx/9300 appliance, log in to FCM and navigate to the Platform Settings tab.NTP version 4 is backwards compatible to NTP version 3. Note: NTP version 4 is not officially supported. Supported version changed due to Cisco bug ID CSCve58269 - NTP: change v2 to v3 Older FXOS than 10.2.2.7 use NTP version 2.FXOS 10.2.2.7 and later use NTP version 3.

NTP uses as a transport the UDP port number 123.

All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
