Parameters
number Specify a number for the authentication key. The range is from 1 to 65534.
This number must be the same as the number parameter configured in the ntp
trusted-key command.
md5 Specify that the authentication key is encrypted using MD5 encryption algorithm.
0 Specify that authentication key is entered in an unencrypted format (default).
7 Specify that the authentication key is entered in DES encrypted format.
key Enter the authentication key in the previously specified format.
Defaults NTP authentication is not configured by default. If you do not specify the option [0 | 7], 0 is selected by
default.

Version Description
9.14(0.0) The trusted-key range value is increased from 1 to 65534.
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
After configuring the ntp authentication-key command, configure the ntp trusted-key
command to complete NTP authentication.
The Dell Networking OS versions 8.2.1.0 and later use an encryption algorithm to store the authentication
key that is different from previous versions; beginning in version 8.2.1.0, the system 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 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.
