Usage Information
After configuring the ntp authentication-key command, configure the ntp trusted-key command to
complete NTP authentication.
Dell EMC Networking OS versions 8.2.1.0 and later use an encryption algorithm to store the authentication key
that is different from previous Dell EMC Networking OS versions; beginning in version 8.2.1.0, Dell EMC
Networking OS uses DES encryption to store the key in the startup-config when you enter the ntp
authentication-key command. Therefore, if your system boots with a startup-configuration from an Dell
EMC Networking OS versions prior to 8.2.1.0 in which you have configured
ntp authentication-key, the
system cannot correctly decrypt the key, and cannot authenticate NTP packets. In this case you must re-enter
this command and save the running-config to the startup-config.

Commands
• ntp authenticate — enables NTP authentication.
• ntp trusted-key — configures a trusted key.
ntp control-key-passwd
Configure control key password for NTPQ authentication. NTP control key supports encrypted and unencrypted option.
Syntax
ntp control-key-passwd [encryption-type] password
To delete the control key, use the no ntp control-key-passwd [encryption-type] password
command.
Parameters
encryption-type (OPTIONAL) Enter one of the following numbers:
• 0 (zero) directs the system to store the password as clear text. It is the default
encryption type when using the password option.
• 7 (seven) indicates that a password is encrypted using a DES hashing algorithm. It
specifies a hidden authentication data.
• WORD is the un-encrypted (cleartext) authentication data.
