VLANs & Trunking
Segment a switched network into VLANs, carry them over trunks, and route between them.
Beginner
Access vs. trunk ports
Match the right port mode to end devices versus switch-to-switch links.
Intermediate
Native VLAN mismatch
Spot the risk when two trunk ends disagree on the native VLAN.
Advanced
Inter-VLAN routing design
Choose between router-on-a-stick and a Layer 3 switch as VLANs scale up.
