Help needed to configure NTP client mode in ICX7150-C12

[ph07]

Dear Ruckus Support team,

My Ruckus Unleashed system with one ICX7150 switch and five APs works well. I can configure and monitor all devices in the Unleashed web console or mobile app. I had some issues before but resolved them by reading the forum and Ruckus documentation. Thank you very much for patiently answering the questions in this forum.

I need help with the NTP configuration for the ICX7150 switch. I easily configured APs to sync their time using NTP via the web interface. However, this does not apply to the Ethernet switch, which relies on manual clock configuration. I noticed the switch's clock needs manual adjustments after several weeks when it runs standalone and/or every time there is a power failure, which happens every several months in North California.

 
I configured NTP for APs this way and it seems to work correctly.

For the switch, I used 'ntp' commands in global configure mode to enable NTP, disable the server, leaving only the client mode and added several remote time servers.  This is the current state - I see NTP client mode is enabled, but the switch is not able to connect to any of time services. 

I use AT&T internet service, and I believe my router does not block NTP port 123. I am able to sync my Windows laptop with MS time service (time.windows.com) without any problems. 

Can you please advise how to finish NTP configuration on the switch?

Hi Imran.

Thanks for your reply! As I wrote in my first email, I did use Ruckus documentation to configure NTP. The switch shows NTP client mode as "enabled", and I added several well-known time servers. However, the switch is not able to communicate and sync with either of them. I also verified that the switch clock is set to the correct value, including the TZ setting.  Can you please advise how to diagnose and resolve this issue?

Hi Imran,

Did you have time to reproduce it in your lab? I tried several ideas from the Internet, but nothing worked so far.

Specifically:

* I installed NTP server on my laptop and was able to sync it with public NTP servers which I tried to use with Ruckus switch. It worked easily for my laptop, but not for the switch. At least, I verified that there is no firewall problem or some other networking issue. 
* As additional experiment, I enabled NTP server on my Windows 11, and configured Ruckus switch to use it as one of NTP servers. The laptop and the switch are on the same network and I manage the switch using either terminal or web session from this laptop. Again, the switch did not sync with the NTP server on my laptop and neither with any of the public time servers. 

* Removed TZ information from Ruckus switch clock and configured it to be in GMT time zone. It is very close to the "real time" (Ruckus docs require it to be less than 1,000 seconds away). Did not help as well.

I used these commands to configure NTP client:

ntp
disable serve
server time.windows.com
server time.google.com
server time.cloudflare.com
server ntp.ruckuswireless.com minpoll 5

The current status:

SSH@ICX7150-C12 Switch# show ntp status
Clock is unsynchronized, no reference clock
NTP server mode is disabled, NTP client mode is enabled
NTP master mode is disabled, NTP master stratum is 8
NTP is not in panic mode

SSH@ICX7150-C12 Switch# show ntp associations

As we can see, the NTP client mode and several clock references are configured, but none is synced.
Any suggestions are very welcome.
