Configuring NTP on Cisco device

Network Time Protocol also know as NTP is very essential component on networking devices. When devices are growing on the data center, it is not possible to set time manually on each devices. NTP protocol play major role here while setting the time automatically. There are few benefits of having same time on each devices. It is helpful to troubleshoot device issues such as hardware failures, devices up / down  and also identifying the application levels issues by reading the logs file. Here I’m going to show you how to configure time of Cisco router using NTP protocol but remember if you have different Cisco devices running IOS , then the process is same as below. So let’s go through configuring NTP on Cisco .

1) Peering with NTP server

2) Set NTP to update / sync hardware clock

3) Cisco Set the time zone

That’s all , so how to verify whether NTP is working properly.

i) Check ntp status

This will show local clock is synced with the remote NTP server.

ii) Check ntp associations

if the the sync is successful, there will be “*” symbol infornt of address entry like below.

 

 

iii) NTP associations in detail
