4 Command Line Interface spanning-tree protocol-migration This command re-checks the appropriate BPDU format to send on the selected interface. Syntax spanning-tree protocol-migration interface interface • ethernet unit/port - unit - Stack unit. (Range: 1-8) - port - Port number. (Range: 1-26) • port-channel channel-id (Range: 1-4) Command Mode Privileged Exec 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 Console#spanning-tree protocol-migration eth 1/5 Console# show spanning-tree This command shows the configuration for the common spanning tree (CST) or for an instance within the multiple spanning tree (MST).
