Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
What do you get from a "dis ntp status", should be....
[SWITCH-00]dis ntp status
Clock status: synchronized
Clock stratum: 4
Reference clock ID: 192.168.100.1
Nominal frequency: 100.0000 Hz
Actual frequency: 100.0000 Hz
Clock precision: 2^18
Clock offset: 29.8469 ms
Root delay: 7.23 ms
Root dispersion: 53.85 ms
Peer dispersion: 0.00 ms
Reference time: 11:01:46.692 UTC Apr 11 2017(DC97361A.B14A3C64)
[SWITCH-00]
If you are synchronizing to an external server, then ensure that you are allowing this out through the firewall.

Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
No I get "unsynchronized."
There seems to be something missing, something to tell the ntp client to start.
Following another answer here, I tried "ntp-service enable" but that was rejected by the cli.

Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
So, consider my question to be: What do you tell system-view in a _cmdline-mode cli over telnet, in order to make the ntp client to start?

Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
in my recent-FW V1910, loggin in over telnet, enabling _cmdline-mode and entering system-view, the command "ntp-service enable" is rejected.

What reference clock are you trying to get NTP from?
Please share the output of "dis ntp trace" as below...

Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
I found it. It was entirely unrelated to the ntp-service command.
I had somehow lost the wildcard 0.0.0.0 static route, but once I put that back in, ntp started nicely.
Using the two commands you showed.

Re: Unable to configure NTP on HP 1910 / a5500 / 1920 etc
Thats great news, glad you got it sorted.
I couldnt figure out why it wasnt working unless for some reason you couldnt see the ip address of the ntp reference clock :)
