Virtual LAN provides location independence to the users, able to save the bandwidth, manage the device, cost effective for the organization are some of the facilities provided by the Virtual LAN.

VLAN hopping can be used to steal passwords and other sensitive information from specific network subscribers. VLAN hopping can also be used to modify, corrupt, or delete data, install spyware or other malware programs, and propagate virus es, worms, and Trojan s throughout a network. >> Stay up to date by receiving the latest IT term daily. It also performs very well at a lot of other specific tasks that most other tools can’t handle, like sending invalid frames, injecting your own 802.11 frames, combining technique (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel). Here is some typical Scapy commands:
