Configuring secure NTP

5

1. Select Services > Secure NTP from the main menu tree.

2. Select the NTP Status tab.

3. Refer to the SNTP Status field to review the accuracy and performance of the switch’s ability to

synchronize with a NTP server:

Leap

Indicates if a second will be added or subtracted to SNTP packet transmissions, or
if the transmissions are synchronized.

Stratum

Displays how many hops the switch is from its current NTP time source.

Reference

Displays the address of the time source the switch is synchronized to.

Frequency

A SNTP server clock’s skew (difference) for the switch

Precision

Displays the precision (accuracy) of the switch’s time clock (in Hz). The values that
normally appear in this field range from -6 for mains-frequency clocks to -20 for
microsecond clocks found in some workstations.

Reference time

Displays the time stamp at which the local clock was last set or corrected.

Clock Offset

Displays the time differential between switch time and the NTP resource.

Root delay

The total round-trip delay in seconds. This variable can take on both positive and
negative values, depending on the relative time and frequency offsets. The values
that normally appear in this field range from negative values of a few milliseconds
to positive values of several hundred milliseconds.

Root Dispersion

Displays the nominal error relative to the primary time source in seconds. The
values that normally appear in this field range from 0 to several hundred
milliseconds.
