VLAN and Port Assignments
| Ports | VLAN Number – Name | Network |
|---|---|---|
| F0/1 – F0/5 | VLAN 56 – Management&Native | 192.168.56.0/24 |
| F0/6 – F0/10 | VLAN 30 – Guest(Default) | 192.168.30.0/24 |
| F0/11 – F0/17 | VLAN 10 – Faculty/Staff | 192.168.10.0/24 |
| F0/18 – F0/24 | VLAN 20 – Students | 192.168.20.0/24 |
Objectives
- Part 1: Find and Correct the Network Errors
- Part 2: Document the Corrections to the Network
- Part 3: Implement Solutions and Test Connectivity
Background
In this activity, you will troubleshoot a misconfigured VLAN environment. The initial network has errors. Your objective is to locate and correct the errors in the configurations and establish end-to-end connectivity. Your final configuration should match the Topology diagram and Addressing Table. The native VLAN for this topology is VLAN 56.
Part 1: Discover and Document Issues in the Network
Use the Topology, Addressing Table, VLAN and Port Assignments table and your knowledge of VLANs and trunking to discover issues in the network. Complete the Documentation table listing the problems you discovered and potential solutions.
Documentation
| Problems | Solutions |
|---|---|
| S2 G0/1 is configured as an access port instead of a trunk port | Implement switchport mode trunk command |
| S1 is not configured with any VLANs, just trunks. | Use the necessary commands on S1 to configure the VLANs and set the native VLAN on the trunks. |
| S3 ports are not assigned to a VLAN | Implement switchport access vlan # command based the Port Assignments table |
| There is a native VLAN mismatch | Configure the trunk ports on S1 in native VLAN 56. |
Part 2: Implement the Solution and Test Connectivity
Verify PCs on the same VLAN can now ping each other. If not, continue to troubleshoot.
Suggested Scoring Rubric
Packet Tracer scores 70 points. Documentation in Part 2, Step 3 is worth 30 points.
