The Palo Alto Networks firewall can be configured to use specified Network Time Protocol (NTP) servers. For synchronization with the NTP server(s), NTP uses a minimum polling value of 64 seconds and a maximum polling value of 1024 seconds. These minimum and maximum polling values are not configurable on the firewall.


Once the Palo Alto Networks device goes through the initial synchronization process and synchronizes the system clock, it will poll the NTP server within the default minimum and maximum range.

To manually restart the NTP process, use the following CLI command:

> debug software restart ntp


To view whether the NTP process has a new PID, execute:

         >  show system software status | match ntp

          Process  ntp            running  (pid: 2216)


To verify NTP state, use the show ntp CLI command as in the following examples:

Example of successful connection:

> show ntp

NTP state:

    NTP synched to

    NTP server connected: True

    NTP server connected: True


Example of unsuccessful connection (Could be due to: Error in NTP Sync Status Display)

> show ntp

NTP state:

    NTP synched to LOCAL

    NTP server connected: False

    NTP server connected: False


To verify current system date and time, use the following CLI command:

> show clock
