Today i found my ex2300 NTP not working. All the configuration are same with other site. But, not sure why it not working. This unit i just receive from my vendor. Previously it has problem, this unit always soft restart. Then our vendor doing firmware upgrade from 15.1X53-D56 to 18.2R2.6.

Then when i try to associate the ntp, i got this error :
kakigodek@EX2300T4-U-GR1-1# run show ntp associations
localhost: timed out, nothing received
***Request timed out
when i run command “Show ntp status” i get this :
kakigodek@EX2300T4-U-GR1-1# run show ntp status
localhost: timed out, nothing received
***Request timed out
After a few hour looking line by line the command… so weird, why ntp not working. I already set the ip, and allow it on firewall filter. I try read some post inside Juniper forum and found 1 guy give some hint. Deactivate firewall family inet filter PROTECT-RE term BFD from destination-port 3784. So i try and……
kakigodek@EX2300T4-U-GR1-1# deactivate firewall family inet filter PROTECT-RE term BFD from destination-port
and commit, then i try again to associate ntp. This is what i get.
kakigodek@EX2300T4-U-GR1-1# commit
