VLAN DEFINITION (continued): …  hopping attack can occur in either of two 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 …
