Simulates VLAN hopping attacks using switch spoofing and 802.1Q double tagging techniques in authorized lab environments to test VLAN segmentation effectiveness and switch port security. Use during an authorized penetration test to validate trunk port hardening, confirm DTP is disabled on access ports, and demonstrate Layer 2 segmentation bypass risk to network teams.
