Multi-layer switching can be a confusing concept for students taking Cisco courses, and is only complicated further by more new terms arising, such as layer-3 and layer-4 switching. KnowledgeNet Instructor Jeremy Cioara employs concrete analogies to fully explain the concept of Cisco multi-layer switching in this article.
"What is layer-3 switching?" This question pops up frequently in our Cisco e-learning classes. Although the classes have hundreds of students with more than a thousand possible questions collectively, the confusion about the correct definition of layer-3 switching often seems to be uppermost on their minds. To add to the confusion, synonyms such as "layer-4 switching" and "multi-layer switching" have sprung up in the industry as well.
