FTD and Lina Time Difference - Any way to force time sync?

gundamdude

I am currently trying to diagnose an issue we are seeing where the time shown in our FTD HA pair is differing from the time listed in Lina, in some cases up to an hour difference.  Below is an example (FTD is showing the correct time, Lina is incorrect):

 

Our current setup:

x2 Firepower 4115 (FXOS 2.8.1.164) running FTD 6.6.4 containers in HA

 

#FTD1

> show time
UTC - Thu Jun 30 12:49:24 UTC 2022
Localtime - Thu Jun 30 08:49:25 EDT 2022

> system support diagnostic-cli
Attaching to Diagnostic CLI ... Press 'Ctrl+a then d' to detach.
Type help or '?' for a list of available commands.

We've been able to get around this time sync issue so far by rebooting both the primary and secondary FTD simultaneously. What I've noticed is that prior to the failover sync, the FTD and Lina times are synced up. Once sync occurs, it pulls the Lina time from the active device.

 

My question is if anyone knows of a way to force a time sync within Lina outside of having to reboot both primary and secondary containers and possibly incur downtime?

Make sure your Firepower Chassis Manager has a valid ntp server configured. It should then sync to the FTD instance(s) running on the chassis.
