UMGC – Spring 2021 CMIT-455 CCNP ENCOR v8 Tutorial Packet Tracer 5.2.2 Supplement: LACP & XOR Hash

In this comprehensive supplemental tutorial to the Cisco Networking Academy’s CCNP ENCOR v8 Packet Tracer activity 5.2.2 (Configure EtherChannel) I go into the deep end of the EtherChannel pool by walking you though a 16-port member port channel configuration with the IEEE 802.1AX Link Aggregation Control Protocol (LACP) and then break down how two (2) Cisco 2960 will hash (and subsequently pick a member link across which traffic will flow) based on source and destination IP. We cover the CLI ‘test etherchannel’ command and its semantics demonstrating how you can leverage the CLI to predict across which link traffic would flow. 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 and 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!
