Configure NTP
Last Updated: July 07, 2026
When running in an asynchronous DAA environment, Network Time Protocol (NTP) should be configured instead of PTP. It is also required to have NTP configured on all servers not running PTP (to ensure time stamps of logs are consistent across multiple servers and VPS 1 and 2). To enable NTP, perform the following steps on the VUE application server:
  1. Disable PTP if it is enabled.
    1. Edit the linuxPtp.conf file and set PTP IPv6 address to a bogus address.
      $ sudo vi /var/opt/vue-server/ptp/linuxPtp.conf
    2. Restart PTP to have new configuration take effect.
      $ sudo docker-compose -f /arris/compose/vue-ptp-compose.yml restart
  2. Enable NTP.
    1. Edit the chrony.conf file and specify the NTP server IPv4 address at end of file.
      $ sudo vi /etc/chrony.conf
      For example:
      server 10.237.162.107 burst iburst minpoll 4
    2. Enable and start chrony daemon.
      $ sudo systemctl stop chronyd
$ sudo systemctl enable chronyd
$ sudo systemctl start chronyd
    3. Verify chrony status.
      $ chronyc tracking
$ chronyc sources
