Usage

Information

After configuring the ntp authentication-key command, configure the ntp trusted-key

command to complete NTP authentication.

Dell Networking OS versions 8.2.1.0 and later use an encryption algorithm to store the authentication key

that is different from previous Dell Networking OS versions; beginning in version 8.2.1.0, Dell 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 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.
