I'm trying to set up our core Nexus 9000 to be an NTP server for our other network devices. The Nexus is pulling time info from the Internet without a problem, but I cannot get other internal devices to connect to the Nexus to sync with it. It just seems to time out.
I have no idea what I could be doing wrong or what else I can do to try to troubleshoot.
Any thoughts or suggestions?
Thanks.

Here is my current NTP config. Short and simple:
ntp server 128.138.140.44 use-vrf default
ntp server 129.6.15.28 use-vrf default
ntp server 132.163.96.1 use-vrf default
ntp server 132.163.97.1 use-vrf default
ntp source <internal IP>
ntp logging
ntp master 8

ok thank you, what IP address client pointing towards nexus 9K IP, is that IP reachable from client device ?
why i was asking this was, most of them configured in VRF.

I set the clients to point to the same IP that I used set as the "ntp source" IP.
It is pingable by all clients.

I just tried a different IP, and now one of the switches synced.
I'm wondering if it doesn't like that the NTP request is going "through" the Nexus?
I'm going to try this on a couple of other devices to see what happens.

as long they pinging and you do not have any ACL which is blocking, then it should work.
show ntp
also enable debug and see if you getting required to nexus 9K from end device
