Administrator Guide

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.
