In this video tutorial we take a look at the Network Time Protocol (NTP). We go over the different ways to configure both NTP servers and NTP clients. We perform NTP static client configuration as part of the Packet Tracer activity and then we examine how to configure an NTP broadcast server and broadcast client. We examine Wireshark packet captures to dig deeper into the UDP-based NTP packets and confirm the source and destination port of 123 along with the NTP version number (v4). We close out by looking at a number of the different NTP servers available on the Internet from NIST, Google, and Facebook. Enjoy!
***This video is an in-depth tutorial and is far more than simply an answer key to the aforementioned Packet Tracer activity. This tutorial is being made to assist my UMGC CMIT-455 learners in their journey through the ENCOR v8 material so, if you are just looking for a shortcut or easy answers for the activity, this is not the video you should watch. However, if you are looking to gain a deeper understanding on inter-VLAN routing configuration and designs, my hope is that this will increase your comprehension and help you to become a better and more effective network engineer. Enjoy!
*This techtorial/Packet Tracer activity is all done running Cisco Modeling Labs (CML) v2.1.1-b19, some physical routers in my Evil Command Center Lab and/or Packet Tracer version 7.3.1.0362 (for the Mac) which was just recently released! The MINIMUM version you can use for any of the new CCNAv8 curriculum activities is Packet Tracer v7.3.0! Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!
