Command Usage
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).
Example

Use this command to show the spanning tree configuration.
