Unable to configure NTP on HP 1910 / a5500 / 1920 etc

HI! Im having troubles configuring NTP protocol on, for example, hp 1910 using comware 5.20.99. I follow this exact instructions

http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=mmr_kc-0122003 


[SWCORE]ntp-service authentication enable
[SWCORE]ntp-service authentication-keyid 24 authentication-mode md5 aNiceKey
[SWCORE]ntp-service reliable authentication-keyid 24

Then i configure from the web interface any other switch as the tutorial says, and nothing happens. Maybe i'm missing something. Please help!

 

Thanks in advance

Generally you don't need to have ntp authentication unless your IT or security folks require it.  You also configure this through the web and not the CLI as that is restricted.

The only thing you need to set is the source interface where the NTP protocol should be able to get to the server and the IP addresses of 1 or 2 time servers.  I just did it on mine and it worked fine.

I would remove whatever you configured through the CLI before playing with the web configuration.

Hi

To configure an ntp server, following commands are enough to let it work

ntp-service enable
ntp-service unicast-server <ip-address>

After this just wait till the switch syncs with the server.

Kind regards

Hi Hp-Browniee!

That is true for the more featured switches.  For the low end switches, like the 1910 that don't have a CLI, that wouldn't work. 

In most cases, that is what I do on the higher end switches.

You can enable the CLI on the 1910 with a specific command.

Then you can use all the comware commands. :)

 

Kind regards

To be - literally - correct the 1910 permits to configure NTP Client settings (AFAIK it doesn't act as NTP Server, it operates as a NTP Client): it can be synchronized to an external NTP Server.

See (Web GUI) Device -> System Time -> Network Time Protocol. Should be a very simple configuration.

Just curious: which Firmware version is running your HPE OfficeConnect 1910 now?

HP-Browniee,

While that may be true, that was not how the product was sold.  Enabling the CLI is only intended for diagnostic purposes only.  The supported configuration method is the Web GUI.

On my 1920, NTP is in the GUI, and these settings work for me:

NTP works on my 1920s ok.

The only two commands I have in them are:

 

 ntp-service source-interface Vlan-interface100

 ntp-service unicast-server <ip_address>

 

I get my NTP from the firewall which itself is synced to pool.ntp.org

I tried the following;

ntp-service source-interface Vlan-interface 1

ntp-service unicast-server <ip_address>

 

in a 1910 switch with 5.20.R1518P01 software, however "display clock" and "display ntp-service status" show that ntp is not active.

 

What am I missing???
