NTP

The Valtix Gateway uses NTP to ensure its time in sychronized. NTP operates through the Management interface and is configured as part of the Linux shell used for management purposes. The NTP default configuration is slightly different for each CSP as follows:

  • AWS: 2.centos.pool.ntp.org, 169.254.169.123
  • Azure: 0.centos.pool.ntp.org, 1.centos.pool.ntp.org, 2.centos.pool.ntp.org, 3.centos.pool.ntp.org
  • GCP: metadata.google.internal
  • OCI: 0.centos.pool.ntp.org, 1.centos.pool.ntp.org, 2.centos.pool.ntp.org, 3.centos.pool.ntp.org, 169.254.169.254

In order to override the default configuration, the NTP Profile can be created and applied to each Gateway. Once the NTP Profile is applied to the Gateway, the new configuration will be used. This operation applies immediately and does not a blue/green Gateway (re)deployment.
