Usage
Information
After configuring the
ntp authentication-key
command, to complete NTP authentication, configure the
ntp trusted-key
command.
FTOS versions 8.2.1.0 and later use an encryption algorithm to store the authentication key that is
different from previous FTOS versions; beginning in version 8.2.1.0, FTOS uses DES encryption to
store the key in the startup-config when you enter the command
ntp authentication-key
. Therefore, if
your system boots with a startup-configuration from an FTOS 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.
