“I need a trunk,” Alex whispered.
Trunks are point-to-point links between switches that carry traffic for multiple VLANs. Without trunking, VLAN 10 on Switch 2 could not talk to VLAN 10 on Switch 3. 3.3.12 packet tracer - vlan configuration.pka
Before diving into the specific commands required by the lab, it is crucial to understand why this exercise exists. In a standard flat network, every device sees every broadcast packet. If you have 50 computers connected to a single switch without VLANs, a broadcast sent by one computer is processed by all 49 others. “I need a trunk,” Alex whispered
In the landscape of Cisco networking education, few tools are as pivotal as Cisco Packet Tracer. It serves as the bridge between theoretical textbook knowledge and the practical command-line interface (CLI) skills required in the real world. Among the myriad of labs provided in the Cisco Networking Academy (NetAcad) curriculum, the activity stands out as a critical milestone. Before diving into the specific commands required by
But Alex made a classic mistake. On S2, Alex forgot to allow VLAN 30 on the trunk to S3. Suddenly, Staff PCs on S2 couldn’t talk to Staff PCs on S3.
First, access the switch’s CLI (Command Line Interface) via Packet Tracer.
