In a lab, I have a CSR that is configured as NTP master. The CSR is showing as synchronised:
R1#show ntp status
Clock is synchronized, stratum 3, reference is 185.53.93.157
nominal freq is 250.0000 Hz, actual freq is 249.8750 Hz, precision is 2**10
ntp uptime is 565600 (1/100 of seconds), resolution is 4016
reference time is E0432D98.9D82A706 (10:36:08.615 GMT Mon Mar 25 2019)
clock offset is 262.2631 msec, root delay is 25.04 msec
root dispersion is 1448.53 msec, peer dispersion is 940.82 msec
loopfilter state is 'CTRL' (Normal Controlled Loop), drift is 0.000499999 s/s
system poll interval is 256, last update was 59 sec ago.
The CUCM never shows as synchronised despite the CSR showing as accessible:
admin:utils ntp status
ntpd (pid 12762) is running...
remote refid st t when poll reach delay offset jitter
==============================================================================
10.10.0.254 185.53.93.157 3 u 29 64 1 4.537 4.708 2.603
unsynchronised
polling server every 64 s
Current time in UTC is : Mon Mar 25 10:37:52 UTC 2019
Current time in Europe/London is : Mon Mar 25 10:37:52 GMT 2019
Why do I have difficulty getting CUCM to show synchronised?
I am assuming that I will be unable to install IMP server with the NTP in this state?
Many thanks
