Trunking

Learn how to configure 802.1Q VLAN Trunking between two switches step-by-step! When you have devices in the same VLAN spread across multiple switches in your network, standard access ports aren't enough. In this tutorial, you'll learn how to set up a trunk link that carries traffic for both VLAN 10 and VLAN 20 across a single connection between two switches. What you will learn in this video: • Access Ports vs. Trunk Links: Understanding why trunking is required between switches. • VLAN Setup: Creating identical VLAN definitions on both switches. • Trunk Configuration: Configuring interface mode to trunk (switchport mode trunk) and enabling 802.1Q encapsulation. • Allowed VLANs: Controlling which VLANs are permitted across the trunk link. • Verification & Troubleshooting: Using show interfaces trunk and show vlan brief commands to verify connectivity.
