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.
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:
did you try set the source to be a loopback or something else in case ntp by default is coming off the mgmt. int when enabled , theres a few bugs In ntp in nexus aswell that were fixed in newer releases for 5ks , 1 I found for your release could expliain it
