Version 11.5.3 - Bug NTP server unreachable after upgrade
I recently noticed in couple of my ltm's, the NTP servers are unreachable after it got upgraded to 11.5.3. But I dont see any relevant article on this bug ID. Nor I observed any daemon log for this.
I was able to find another Q&A though.
[LTM:Active:In Sync] ~ ntpq -np
remote refid st t when poll reach delay offset jitter
==============================================================================
1.1.1.1 .XFAC. 16 u 20d 1024 0 0.000 0.000 0.000
2.2.2.2 .XFAC. 16 u 20d 1024 0 0.000 0.000 0.000
3.3.3.3. .XFAC. 16 u 20d 1024 0 0.000 0.000 0.000
Hope this helps for others running on 11.5.3 to cross verify the ntp server status.
Resolution:
Restart the ntp service.
bigstart restart ntpd
