NTP authentication

Hello everyone,

NTP configuration this suppose to be a simple task, but it really gives me a headache.

server:

ntp authentication-key 1 md5 cisco

ntp master

client

ntp server 172.30.12.1 key 1

ntp authenticate

ntp authentication-key 1 md5 cisco

ntp trusted-key 1

What is wrong with this config?

.Aug 12 11:11:10.651: Authentication key 1

.Aug 12 11:11:10.655: NTP: packet from 172.30.12.1 failed validity tests 10

.Aug 12 11:11:10.655: Authentication failed

Let me know,

Vlad

Found it, it was just a matter of waiting NTP is really slow.

and use on the master

ntp master 3

ntp authenticate

ntp authentication-key 1 md5 cisco

ntp trusted-key 1
