Command Output Descriptions
Field
Description
system peer
The current synchronization source.
system peer
mode
mode
The mode of the association between the system and the synchronization source. The association can operate in
one of the following modes as defined in RFC 1305:
symmetric activesymmetric passiveclientserverbroadcast
one of the following modes as defined in RFC 1305:
symmetric activesymmetric passiveclientserverbroadcast
leap indicator
The two-bit code that will be used to indicate the insertion of a leap second in the NTP timescale.
stratum
The quality level of the system clock.
precision
A signed integer that indicates the precision of the system clock.
root distance
The round-trip packet delay to the primary reference source. The delay is measured in seconds.
root dispersion
The maximum error relative to the primary reference source. The error is measured in seconds.
reference ID
The code that identifies the current synchronization source.
reference time
The local time that the system was last updated using NTP.
system flags
Indicates various communication parameters between the system and the server. The possible flags are as
follows:
auth: Enables the server to synchronize with unconfigured peers only if the peer has been correctly
authenticated using either public key or private key cryptography.bclient: Enables the server to listen for a
message from a broadcast or multicast server, as in the multicast client command with default address.calibrate:
Enables the calibrate feature for reference clocks.kernel: Enables the kernel time discipline, if
available.monitor: Enables the monitoring facility.ntp: Enables time and frequency discipline. In effect, this
switch opens and closes the feedback loop, which is useful for testing.pps: Enables the pulse-per-second (PPS)
signal when frequency and time is disciplined by the precision time kernel modifications.stats: Enables the
statistics facility.

jitter
The maximum amount of fluctuation within the synchronization source due to random noise.
stability
The stability of the clocking source in parts per million (ppm).
broadcastdelay
The round-trip delay for broadcast messages in seconds.
authdelay
The round-trip delay for authentication messages in seconds.
