Check to see if the lo0 interface has a firewall filter applied to it. If so, this is potentially blocking ntp access so have a look at the content of that filter.

Hi tgreaser,
You might be right about ntp filters at config level since we don't manage them and ntp works for internal gateway and other device s
But as you can see from screen shot even time.google.com fails .
In firewall we have allowed from trust to untrust any.

Your time is very far off so no matter what.
run set date YYYYMMDDhhmm.ss
Second. Can you post your ntp servers config .. From the lost ntp may not be running or has its own filter dropping src 10.103.16.42 range

Hi Team,
We are facing issue with NTP sync with our switches as the log messages shows that NTP Server is not reachable, but the connectivity looks fine between the devices.
config we have ::
set system ntp server 10.103.36.150
set system ntp server 10.103.36.151
set system ntp server 216.239.35.0 prefer
set system ntp source-address 10.103.16.42
this is our switching architecture ::
we have configured all vlans as layer 3 in gateway device.
we don't have a firewall in between the ntp server and switches.
Please let me know if i'm missing anything.
