Feature	Description	Changed in Release	Where Documented
Pseudowire Redundancy	Pseudowire redundancy allows you to configure a backup pseudowire in case the primary pseudowire fails.	Release 6.2.1	Pseudowire Redundancy
BPDU Guard	The Bridge Protocol Data Units (BPDU) Guard is a Cisco feature that protects against misconfiguration of edge ports. When MSTP port fast is configured on an interface, MSTP considers that interface to be an edge port and removes it from consideration when calculating the spanning tree. When BPDU Guard is configured, MSTP additionally shuts down the interface using error-disable if an MSTP BPDU is received.	Release 6.2.1	Configure BPDU Guard
