Hello All,
I need help or "direction to search" for the following issue.
I have a number of MX/SRX devices in my network configured with NTP servers. The configuration looks similar on all devices
set system ntp server A.B.C.D
set system ntp server A1.B1.C1.D1
The A.B.C.D are private IP of the NTP servers configured in my network.
The show ntp associate, show ntp status shows no issues and looks as follows (almost identical on all devices)
show ntp status
status=0664 leap_none, sync_ntp, 6 events, event_peer/strat_chg,
version="ntpd 4.2.0-a Fri Dec 29 07:11:30 2017 (1)", processor="amd64",
system="FreeBSDJNPR-10.3-20171207.04b87e3_buil", leap=00, stratum=3,
precision=-23, rootdelay=38.992, rootdispersion=55.057, peer=61686,
refid=A.B.C.D,
reftime=e36a4ca4.aca1c202 Thu, Nov 26 2020 15:47:48.674, poll=10,
clock=e36a4cb9.c5ab9b79 Thu, Nov 26 2020 15:48:09.772, state=4,
offset=0.514, frequency=30.517, jitter=0.793, stability=0.002
show ntp associations
remote refid st t when poll reach delay offset jitter
===============================================================================
+A1.B1.C1.D1 136.243.21.38 3 - 138 512 377 11.997 0.144 0.428
*A.B.C.D 90.187.99.165 2 - 79 512 377 12.198 0.838 0.001
The issue is that some of the devices are showing the Time Source: LOCAL CLOCK and some are showing NTP CLOCK
show system uptime
Current time: 2020-11-26 15:50:04 UTC
Time Source: LOCAL CLOCK
show system uptime
Current time: 2020-11-26 15:50:41 UTC
Time Source: NTP CLOCK
The difference I noted (not confident) is that the devices with "Time Source: NTP CLOCK" do have a routing/reachability to the refid, and the other with "LOCAL CLOCK" looks to be filtered by FW (not yet confirmed).
But All devices do have full access to the NTP servers (A.B.C.D and A1.B1.C1.D1).
So my questions will be:
1. Does "Time Source" from the show system uptime indicate the "Time Source" used by the system (so in case of LOCAL - I do not consider NTP servers). Or it's just cosmetic?
2. Is there any way to debug/check what is the current source of time for the system?
3. Any way to debug the Time Source?
Thank you in advance,
Andrei
