NTP authentication is not configured by default. If you do not specify the option [0 | 7], 0 is selected by default. CONFIGURATION Version 8.2.1.0 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.1.1.0 Added options [0 | 7] for entering authentication key. Support added for S-Series Support added for C-Series Introduced for E-Series After configuring the ntp authentication-key command, configure the ntp trusted-key command to complete NTP authentication. 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. ntp authenticate ntp trusted-key Enables NTP authentication. Configure a trusted key. ntp broadcast client c e s Set up the interface to receive NTP broadcasts from an NTP server.
