NTP status command output descriptions

Field

Description

synchronized

Indicates that the system clock is synchronized to the NTP server or peer.

stratum

Indicates the stratum number that this system is operating. Range 2..15.

reference clock

The IPv4 address or first 32 bits of the MD5 hash of the IPv6 address of the peer to which the clock is synchronized.

precision

Precision of the clock of this system in Hz.

reference time

Reference time stamp.

clock offset

Offset of clock (in milliseconds) to synchronized peer.

root delay

Total delay (in milliseconds) along the path to the root clock.

root dispersion

Dispersion of root path.

peer dispersion

Dispersion of root path.

system poll interval

Poll interval of the local system.

last update

Time the router last updated its NTP information.

server mode

Status of the NTP server mode for this device.

client mode

Status of the NTP client mode for this device.

master mode

Status of the master mode.

master stratum

Stratum number that will be used by this device when the master is enabled and no upstream time servers are accessible.

panic mode

Status of the panic mode.
