DEFINITION: VLAN hopping (virtual local area network hopping) is a method of attacking a network by sending packets to a port that is not normally accessible from a given end system. (A VLAN is a local area network with a definition that maps devices on some other basis than geographic location - for example, by department, type of user, or primary application.)

VLAN DEFINITION (continued): … ways. If a network switch is set for autotrunking, the attacker turns it into a switch that appears as if it has a constant need to trunk (that is, to access all the VLANs allowed on the trunk port). In Cisco's Dynamic Trunking Protocol (DTP), the susceptibility of a system to this form of VLAN hopping can be minimized by turning off the autotrunking feature (DTP off) on all switches that do not need to trunk. In the second form of VLAN hopping, the hacker transmits data through one switch to another by sending frames with two 802.1Q tags, one for the attacking switch and the other for the victim … VLAN definition sponsored by SearchSecurity.com, powered by WhatIs.com an online computer dictionary
