NTP not working on Nexus 5548

Issue: I have bad NTP on my Nexus 5548 no matter what device I point it at. I pointed it at my GPS device to which it should see because I see the mac address of the GPS device when I do a sh mac add | in 254. I then pointed the Nexus 5548 at two other switches and still did not get it to change it's time.

I also have ntp logging turned on and no logs are hitting my logs.

IOS: n5000-uk.9-kickstart.5.2.1N1.5.bin

Model: Cisco Nexus 5548

Config for NTP:

ntp server server *.*254.80 use-vrf management

ntp logging

hi

are you using the oob mgmt. interface , if not remove the use-vrf section just have ntp sever x.x.x.x prefer , its only required for oob and it could be isolating the ntp address from normal route table

I have a oob mgmt interface configured but I do not want ntp to use it. I want ntp to use what it finds in it's mac cache since it see the ntp device there.  I changed the command to ntp server *.*.254.80 prefer but when I use the command sh ntp status I get:

Distribution:Disabled

Lost operational state: No session

Still wondering what the issue could be.
