The following table provides descriptions of the show ntp associations detail command output.

show ntp associations detail Command Output

Field

Description

server

Indicates that the server is statically configured.

symmetric active peer

Indicates that the peer is statically configured.

symmetric passive peer

Indicates that the peer is dynamically configured.

sys_peer

This peer is the system peer.

candidate

This peer is chosen as candidate in the combine algorithm.

reject

This peer is rejected by the selection algorithm.

falsetick

This peer is dropped as a falsticker by the selection algorithm.

outlier

This peer is dropped as an outlier by the clustering algorithm.

stratum

The stratum number

ref ID

The IPv4 address or hash of the IPv6 address of the upstream time server to which the peer is synchronized.

time

The last time stamp that the peer received from its master.

our mode

This system's mode relative to the peer (active/passive/client/server/bdcast/bdcast client).

peer mode

Mode of peer relative to this system.

our poll intvl

This system's poll interval to this peer.

peer poll intvl

The poll interval of peer to this system.

root delay

The delay along the path to root (the final stratum 1 time source).

root disp

Dispersion of the path to root.

reach peer

The peer reachability (bit string in octal).

delay

Round-trip delay to the peer.

offset

Offset of the peer clock relative to this clock.

dispersion

Dispersion of the peer clock.

precision

Precision of the peer clock.

version

NTP version number of the peer.

org time

The originate time stamp of the last packet.

rcv time

The receive time stamp of the last packet.

xmt time

The transmit time stamp of the last packet.

filter delay

The round-trip delay, in milliseconds, of the last 8 samples.

filter offset

The clock offset, in milliseconds, of the last 8 samples.

filter error

Approximate error of the last 8 samples.
