BPDU Attack Protection This window is used to view and configure the BPDU attack protection settings. In generally, there are two states in the BPDU attack protection function. One is normal state, and another is under attack state. The under attack state have three modes: drop, block, and shutdown. A BPDU protection enabled port will enter an under attack state when it receives one STP BPDU packet and it will take action based on the configuration. Thus, BPDU protection can only be enabled on the STP-disabled port. BPDU protection has a higher priority than the FBPDU setting configured by configure STP command in the determination of BPDU handling. That is, when FBPDU is configured to forward STP BPDU but BPDU protection is enabled, then the port will not forward STP BPDU. BPDU protection also has a higher priority than the BPDU tunnel port setting in determination of BPDU handling. When a port is configured as a BPDU tunnel port for STP, it will forward STP BPDU but if the port is BPDU protection enabled, the port will not forward STP BPDUs.

BPDU Attack Protection
This window is used to view and configure the BPDU attack protection settings. In generally, there are
two states in the BPDU attack protection function. One is normal state, and another is under attack
state. The under attack state have three modes: drop, block, and shutdown. A BPDU protection
enabled port will enter an under attack state when it receives one STP BPDU packet and it will take
action based on the configuration. Thus, BPDU protection can only be enabled on the STP-disabled
port.
BPDU protection has a higher priority than the FBPDU setting configured by configure STP command
in the determination of BPDU handling. That is, when FBPDU is configured to forward STP BPDU but
BPDU protection is enabled, then the port will not forward STP BPDU.
BPDU protection also has a higher priority than the BPDU tunnel port setting in determination of
BPDU handling. When a port is configured as a BPDU tunnel port for STP, it will forward STP BPDU
but if the port is BPDU protection enabled, the port will not forward STP BPDUs.
