Configuring NTP on Firepower module

Colin Higgins — Sun, 10 Mar 2019 13:22:17 GMT

Does anyone know how I can configure NTP on a Cisco FirePower module for a ASA5500 series FW?

I did the initial setup, registered the module with my defense center, but now I need to change the NTP settings. Can't seem to figure out where to do this, and if I go through setup again, I am worried it is going to mess up my registration.

The best and recommended way to setup NTP is to make it part of the system policy in the FireSIGHT Management Center (FMC).

System > Local > System Policy. Go under Time synchronization and there in the Supported Platforms section set the NTP to be "Via NTP from Defense Center" (aka FMC). Higher up in that section, point your "Defense Center" to an authoritative NTP server or set of servers. Save policy and Exit and then deploy it.

Otherwise you have to run setup on the module again. It should pre-populate the setup questions with the current system values.

Thanks Marvin! Everything is

@MSJ1 look under System (Gear icon) > Configuration > Time Synchronization.
