To view the NTP configuration, use the show running-config ntp command in EXEC privilege mode. The following example shows
an encrypted authentication key (in bold). All keys are encrypted.
DellEMC#show running ntp

ntp authenticate
ntp authentication-key 345 md5 5A60910F3D211F02
ntp server 11.1.1.1 version 3

Configuring a Custom-defined Period for NTP time
Synchronization
You can configure the system to send an audit log message to a syslog server if the time difference from the NTP server is greater than a
threshold value (offset-threshold). However, time synchronization still occurs. To configure the offset-threshold, follow this procedure.
• Specify the threshold time interval before which the system generates an NTP audit log message if the system time deviates from the
NTP server.
CONFIGURATION mode
ntp offset-threshold threshold-value
The range for threshold-value is from 0 to 999.
DellEMC(conf)#ntp offset-threshold 9
Configuring NTP control key password
The Network Time Protocal daemon (NTPD) design uses NTPQ to configure NTPD. NTP control key supports encrypted and
unencrypted password options. The ntp control-key- passwd command authenticates NTPQ packets. The default control-key-
passwd authenticates the NTPQ packets until the user changes the control-key using the ntp control-key- passwd command.
To configure NTP control key password, use the following command.
Configure NTP control key password.
CONFIGURATION mode
ntp control-key-passwd [encryption-type] password
Configuring the NTP Step-Threshold
You can configure the NTP step-threshold timer using the following procedure:
• Enter the CONFIGURATION mode.
CONFIGURATION mode
• Run the ntp step-threshold command and ensure to specify a value between 128 milliseconds and 5000 milliseconds (5
seconds).
DellEMC(conf)#ntp step-threshold 5000
Use the no ntp step-threshold command to revert to the default setting of 128 milliseconds.
DellEMC(conf)#no ntp step-threshold
