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 conguring the ntp authentication-key command, congure 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 dierent from previous versions; beginning in version 8.2.1.0, the system 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 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.
