Links on a Switch Now that we've created Access Ports, we review the steps to create Access Ports, and move on to explain the concepts for the second type of link that exits on a switch, Trunk Links. We define and diagraph what a Trunk Link is and demonstrate the process flow for how it works. You'll learn how many VLANs can live on a trunk Link and see the interrelationships with end devices. For this lesson we also review some important standards and explain their relevance to CCNA and the VLAN system.
