SNTP on a LAN Network without Internet access

[S3C]

Hi!

Before getting into detail of what ive done so far and if its even possible what im trying to do.

I got a air-gapped network with 1 FW (Cisco FPR 1010) & and 2 switches (cisco SG350-10) on front and backend of a Esxi server.

Is it possible to setup the switches as NTP servers using their own hardware clock which the Esxi & FW can collect the time from?

Thx

Yes you can have own NTP Server, But suggest to have Statum sync so you not required to change any day light savings other stuff.
