We all know that Ethernet switches switch traffic. In this 1-hour Tech Session, Jim Goughenour takes a deeper look into what is happening behind the scenes. We also examine the different methods of how a Cisco switch actually uses those MAC addresses to make a forwarding decision. This video contains Knowledge Checks intended to test […]

In this 1-hour Tech Session, Keith Edwards discusses Class-based Shaping and Class -based Policing. We also discuss the different logic that the two mechanisms employ, as well as the “Shaping” portion of “Shaped Round Robin” in switches. This video contains Knowledge Checks intended to test your understanding of the topic. We encourage you to pause
