Information

On an MSTP switch, a port configured as an edge port immediately transitions to the Forwarding state.

Only configure ports connected to end-hosts as edge ports. Consider an edge port similar to a port with

spanning-tree portfast enabled.

If you do not enable shutdown-on-violation, BPDUs are still sent to the RPM CPU.
