NTP - PIX - issue

elipschutz · ‎11-10-2003

Hi,

I want the PIX to synchronize with two Windows 2000 domain controllers.

The synchronization works but the PIX does not synch its own clock with the time it gets from the server.

See output from the "show ntp association detail":

and from

"show ntp status":

Clock is unsynchronized, stratum 16, no reference clock

nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6

clock offset is 0.0000 msec, root delay is 0.00 msec

root dispersion is 0.00 msec, peer dispersion is 0.00 msec

Any ideas?

Thanks,

Emanuel

If you are using the default version of 3 and NTP synchronization does not occur, try using NTP version number 2. Many NTP servers run version 2.

Hopefully, this will help. If this works please close and rate. Thanks.
