The 2 Tools Used for STP Attacks
PortFast
- PortFast immediately brings a port to the forwarding state from a blocking state, bypassing the listening and learning states
-
- Apply to all end-user access ports
BPDU Guard
- BPDU guard immediately error disables a port that receives a BPDU
-
- Like PortFast, BPDU guard should only be configured on interfaces attached to end devices
