Hello. Yes I am using mgmt interface and I can ping all the IP addresses from vrf mgmt. There is no problem with reachability. Below are the commands I used:
it was not synchronizing. I tried multiple IP addresses with the same behavior.

What VRF are u using for NTP and form which VSF you ping the NTP server?
If using VRF MGTM you use the OOBM management interface. Is the VRF MGTM configured with a IP and did you ping from this VRF?
Also configure the timezone and consider using ibrust, below a example.
(config)# clock timezone europe/amsterdam(config)# ntp server 172.16.200.1 iburst vrf mgmt(config)# ntp enable(config)# write mem(config)# show ntp status

Hello. I have a problem synchronizing time on a 8320 VSX pair. The given NTP servers are working fine on Cisco switches in the customer environment. However when I try to enable NTP on the Aruba switches, it is not working.
ntp server x.x.x.x
ntp enalble
ntp vrf mgmt
I can ping the IP addresses of the NTP servers. But for some reason it is not working. Any idea what could be the reason NTP is not working properly ? I also came across this point in the guide, "Configure an NTP server with the command ntp server. When configuring a time backward more than five minutes on the Aruba 8320, 8325, or 9300 Switch Series, a reboot is recommended to avoid unusual switch behavior." Why would we need to reboot for a simple configuration task such as NTP and what is the unusual switch behavior this point is referring to ?
Thanks in advance.
