Version Description
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.
