If at any time the switch detects STP BPDUs, including Configuration or
Topology Change Notification BPDUs, it will automatically set the selected
interface to forced STP-compatible mode. However, you can also use the
spanning-tree protocol-migration command at any time to manually
re-check the appropriate BPDU format to send on the selected interfaces (i.e.,
RSTP or STP-compatible).
