So here are the basic principles of this, which ports, the boards of a switch is in dynamic, desirable
mode by default.
If the device connected to the port is a computer.
The mode of the port becomes access and the port is dedicated to that computer.
If the device is another switch, the mode of the port becomes trunk.
So by default, trunk ports have access to all the lands and pass traffic for multiple villains across
the same physical link generally between switches.
So switch spoofing is a type of VLAN hopping attack that works by taking advantage of an incorrectly
configured trunk port.
And a switch spoofing attack, the network attacker configures a system to spoof itself as a switch.
So this spoofing requires the network attack or be capable of emulating to 2.0 one cue and DTP messages.
By taking a sweat into thinking that another sweat is attempting to form a trunk.
An attacker can gain access to all the villains allowed on the trunk port.
So the best way to prevent a BASIX witch spoofing attack is to turn off trunking on Allport, except
the ones that specifically require trunking on a required trunking ports, disable DTP dynamic trunking
protocol and manually enable trunking.
