Here is my config:

 

timesync ntp
no sntp
ntp unicast
ntp server 10.10.4.10 iburst
ntp server 10.10.5.10 iburst
ntp enable
time daylight-time-rule user-defined begin-date 10/01 end-date 04/01
time timezone 600

 

NTP Server is windows DC. 

 

Any ideas?

Re: Aruba 2530 NTP issues

Hi Scott,

 

Can you provide some more details on the NTP server? What version of windows are you using maybe add even output of following command  w32tm /query /configuration when it's standalone NTP server.

 

Thanks in advance!

Re: Aruba 2530 NTP issues

Hi Dobias, 

 

Its Win 2016 Server. Unfortunately i had to move on and no longer have access to the environment. The switches have been configured to talk to an external NTP server now. 

 

When i get some time i'll try and lab this up again.
