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).
