I am just curious whether this behaviour is still valid in newer
switches, like those IOS 12+ ... it sounds to me a very old tricks and
seems the successful rate for this type of attack is very lower
nowadays.

Basically what would happen is all traffic would be flooded to all ports.(No VLANS Yet) This would happen to only 
unkown traffic though, that is MAC addresses that are not in the CAM.

If the VLAN is configured then, only ports on the same VLAN would receive the broadcasts. The nature of VLANs prevent 
broadcast from being delivered to another VLAN.

Hopes this helps.
