To enable the NTP service on on-prem hosts, configure the global NTP service. All global NTP settings are inherited by on-prem hosts that have the NTP service enabled.

When you select the KOD STATUS checkbox, the NTP service sends a KOD packet to the NTP client if the client has exceeded the rate limit. When you clear the checkbox, the NTP service drops the packets but does not send any KOD packet to the client.
- INTER PACKET SPACING SECONDS: If you have enabled rate limiting for the ACL, you can override the default values of inter-packet gap intervals. An inter-packet gap is a pause (measured in seconds) required between NTP packets.
- Average: Specify the minimum average time for an inter-packet pause between two NTP packets. The default is 3.
- Minimum: Specify the minimum time for an inter-packet pause between two NTP packets. The default is 1.
- Monitor: Specify the time (in seconds) for the discard probability for packets once the permitted rate limits have been exceeded. The default is 3000. This option is intended for NTP servers that receive 1000 or more requests per second.
