• An authentication key is composed of a 32-bit integer and 32-byte string of characters.  The integer 

format is hexadecimal.  For an NTP message to be authenticated the NTP client authentication key 
must match the key configured at the NTP server.  This means the authentication keys must be distrib-
uted in advance of configuring the NTP client.  If authentication is disabled but authentication key is 
present, the association will still be unauthenticated.

• Use the version keyword to set the correct version of NTP.

• Use the minpoll keyword to set the minimum poll time for the server. This number is determined by 

raising 2 to the power of the number entered. Therefore, if 4 were entered, the minimum poll time 
would be 16 seconds (2

4

 = 16). The client will poll the server for a time update when the minpoll time 

is exceeded.
