NTP is not sync on cisco Switch 3560 with Server

Recommended Posts

Hi Guys,

We have configured NTP on ADC server & it can able to sync time from public NTP server. But when I configure NTP on  any cisco switch/ router to sync with our ADC its not working.

I am putting configuration & debug output with you. Please go through same & help us to find out exact problem.

Switch NTP config :

ntp logging
ntp server 10.50.5.150 source Vlan5 prefer    <<<<<<< 10.50.5.150 is our ADC server Ip address
