BPDU Attack Protection
This window is used to display 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
has 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.
BPDU protection has a higher priority than the (Forward BPDU) 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. That
is, when a port is configured as BPDU tunnel port for STP, it will forward STP BPDU. But if the port is BPDU
protection enabled. Then the port will not forward STP BPDU.
