VLAN Fundamentals: Creating & Assigning Access Ports

Bundle lab · $29.99

Hands-on CCNA lab to practice creating VLANs on a single Layer-2 switch and assigning access ports. You will segment a flat network into two VLANs, place hosts into the right VLAN, and verify that intra-VLAN pings succeed while inter-VLAN pings fail (no routing present). Includes realistic verification and troubleshooting.

Learning objectives

• Create VLANs on a Cisco Layer-2 switch and verify the VLAN database.
• Assign switch access ports to specific VLANs for host segmentation.
• Validate hosts in the same VLAN/subnet can communicate (ping).
• Validate that hosts in different VLANs/subnets are isolated at Layer-2 (no routing).
• Troubleshoot VLAN membership and port assignment using show commands and host-side tests.

Troubleshooting focus

• Verify every link's interface status and IP addressing (`show ip interface brief`) and correct any interface that is down or misaddressed.
• Confirm each device's running configuration matches the lab objective, and bring any interface, route, or service that is not in its expected state back to health.
• Trace end-to-end reachability with ping/traceroute and isolate the first hop where forwarding fails.
