Usage
Information
After configuring the
ntp authentication-key
command, configure 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 different from previous versions; beginning in
version 8.2.1.0, the system 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 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.
