List of Sample Output
show ntp statusOutput Fields
Table 1 describes the output fields for the show ntp status command. Output fields are listed in the approximate order in which they appear.
Table 1: show ntp status Output Fields
Field Name | Field Description |
|---|---|
status | System status word, a code representing the status items listed. |
leap_none | Indicates a normal synchronized state with no leap seconds imminent. Other options could be leap_add_sec, leap_del_sec, or leap_alarm, indicating a leap second will be added, deleted, or a leap second requirement is upcoming. |
sync_ntp | Indicates the current synchronization source, in this case, an NTP server. Other options include sync_alarm and sync_unspec, both indicating that the router has not been synched. |
x events | Indicates the number of events that have occurred since that last code change. An event is often the receipt of an NTP polling message. |
event_peer/strat_chg | Describes the most recent event, in this case, the stratum of the peer server changed. |
version | A detailed description of the version of NTP being used. |
processor | Indicates the current hardware platform and version of the processor. |
system | Detailed description of the name and version of the operating system in use. |
leap | The number of leap seconds in use. |
stratum | The stratum of the peer server. Anything greater than 1 is a secondary reference source, and the number roughly represents the number of hops away from the stratum 1 server.. Stratum 1 is a primary reference, such as an atomic clock. |
precision | The precision of the peer clock, how precisely the frequency and time can be maintained with this particular timekeeping system. |
rootdelay | The total roundtrip delay to the primary reference source, in seconds. |
rootdispersion | The maximum error relative to the primary reference source, in seconds. |
peer | An identification number of the peer in use. |
refid | Reference identifier of the remote peer. If the reference identifier is not known, this field shows a value of 0.0.0.0. |
reftime | The local time, in timestamp format, when the local clock was last updated. If the local clock has never been synchronized, the value is zero. |
poll | The NTP broadcast message polling interval, in seconds. |
clock | The current time on the local router clock. |
state | The current mode of NTP operation, where 1 is symmetric active, 2 is symmetric passive, 3 is client, 4 is server, and 5 is broadcast. |
offset | Current estimated offset of the peer, in milliseconds. Indicates the time difference between the reference clock and the local clock. |
frequency | The frequency of the clock. |
jitter | Indicates the magnitude of jitter, in milliseconds, between several time queries. |
stability | A measure of how well this clock can maintain a constant frequency. |
