Release M.10.17 Enhancements
Release M.10.17 includes the following enhancement:
■RSTP/MSTP BPDU Protection. When this feature is enabled on a port, the switch will disable (drop the link) of a port that receives a spanning tree BPDU, log a message, and optionally, send an SNMP trap.
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.
