Cisco ntp clock is unsynchronized

If the clock is unsynchronized, the firewall has not yet authenticated or synchronized its time clock with an NTP server. Keep checking the status every minute or so to see if the clock becomes synchronized. If it doesn't, confirm your NTP configuration and authentication keys. View all NTP server associations: In this tutorial, we are going to show you all the steps required to configure date and time using NTP a Cisco Switch 2960 or 3750 using the command-line. Cisco Switch Playlist: On this page, we offer quick access to a list of videos related to Cisco Switch. In case the local host is # controlled by some external source, such as an external oscillator or # another protocol, the prefer keyword would cause the local host to # disregard all other synchronization sources, unless the kernel # modifications are in use and declare an unsynchronized condition. # server 127.127.1.0 # local clock fudge 127 ...

Today I noticed that the clock my Cisco ASA 5505 firewall was running about 15 minutes late, which surprised me since I've set up the NTP client. My two NTP servers 10.10.0.1 and 10.10.0.2 are virtualized Windows Server 2008 R2 domain controllers, and both have the correct time. Configure Network Time Protocol (NTP): If there is an NTP server in the network that provides accurate clock settings, then you can configure the firewall to synchronize its time with the NTP server. Both an authenticated and non-authenticated NTP is supported: ntp 192.168.1.1 ntp peer 192.168.1.1 ntp server 192.168.1.1 They don't sych and when I do a sh ntp status I get the following: Clock is unsynchronized, stratum 16, no reference clock I'm sure I'm doing something wrong.
