Spanning Tree BPDU Protection

The BPDU protection feature is a security enhancement to Spanning Tree Protocol (STP) operation.
It can be used to protect the active STP topology by delimiting its legal boundaries, thereby 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 27.
