Configuring BPDU Protection

BPDU protection is a security feature designed to protect the active STP
topology by preventing spoofed BPDU packets from entering the STP domain.
In a typical implementation, BPDU protection would be applied to edge ports
connected to end user devices that do not run STP. If STP BPDU packets are
received on a protected port, the feature will disable that port and alert the
network manager via an SNMP trap as shown in Figure 3-7.
