Parameters
number Specify a number for the authentication key. The range is
from 1 to 4294967295.
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.

Command History
Version Description
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.
