This time, it's layer 2 - vlan.
(1) PVlan, there are promiscuous and community mode? In promiscuous, the hosts can only talk to the other in the same Pvlan and not other regular vlans? according to Private VLANs (PVLANs) - Promiscuous, Isolated, Community - Cisco Systems
(2) How does double-tag vlan attack work? You tag a frame twice with two different vlans and a native vlan happens to be one, so ok, how does this go through? I wish OCG and IINS guide did a better job explaning how crooks hurt layer 2.
Thanks.
