“Right,” Alex groaned. “The switch doesn’t know which PC belongs to which VLAN. It’s like a hotel front desk that doesn’t ask for your room key.”
Professor Lasky’s note floated at the top of the instructions: “VLANs don’t just happen. You build walls where there are none.”
Remember these key takeaways:
interface gigabitEthernet 0/1 switchport mode trunk switchport trunk allowed vlan 10,20,30
While the specific IP addresses and device names in Packet Tracer files can change with curriculum updates, the structure of the "3.3.12" lab almost always follows a standard template. The topology usually consists of:
! Create VLANs 10, 20, 30, 99, 150 and assign names, for example: S1(config)# vlan 10 S1(config-vlan)# name Faculty/Staff ! Repeat for remaining VLANs as per lab instructions Use code with caution. Copied to clipboard 2. Assign Access Ports
The file extension denotes a Packet Tracer Activity file. Unlike a standard .pkt file (which is just a saved network topology), a .pka file contains a pre-built scenario, specific instructions, and an embedded grading algorithm. When you open the file, you are typically presented with a "Topology" view and an "Instruction" window. The system tracks your progress, providing a completion percentage based on whether your configuration matches the requirements.
