Restarting the Protocol Migration Process
This procedure restarts the protocol migration process and forces renegotiation with neighboring switches. It
reverts the switch to MST mode. It is needed when the switch no longer receives IEEE 802.1D BPDUs after
it has been receiving them.
Follow these steps to restart the protocol migration process (force the renegotiation with neighboring switches)
on the switch.
Before You Begin
A multiple spanning tree (MST) must be specified and enabled on the switch. For instructions, see Related
Topics.
If you want to use the interface version of the command, you must also know the MST interface used. This
example uses GigabitEthernet1/0/1 as the interface because that was the interface set up by the instructions
listed under Related Topics.
