Version Description
7.5.1.0 Introduced on the C-Series.
6.1.1.0 Introduced on the E-Series.
Usage Information
After conguring the ntp authentication-key command, congure 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 dierent 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-cong when you enter the
ntp authentication-
key command. Therefore, if your system boots with a startup-conguration from an Dell Networking OS
versions prior to 8.2.1.0 in which you have congured 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-cong to the startup-cong.
