Trunking configuration

Trunking configuration

- [Instructor] In this video, we want to see how to configure an ethernet trunk. Specifically, we're going to be using the .1Q trunk encapsulation type and we have two links in our topology and we'll set up trunking on both of those links. And then after we're done, we'll verify the trunk creation. Now let's go out to a live interface and set this up. Well, let's begin our configuration on switch SW1. I'll go into global configuration mode and I'll say interface range, using that shortcut gigabit 0/1-2. And by the way the switches I'm using right now are not physical switches. They are emulated switches. I'm using CML, Cisco Modeling Labs. And I'll go into interface range configuration mode for these two interfaces on switch SW1, connecting down to switches SW2 and SW3. And I'll say I want to use the .1Q trunk encapsulation type with the command switchport trunk encapsulation dot1q. And I'll say I want these to be trunk…
