If a link partner is discovered by using STP, click Activate Protocol Migration to
run a Protocol Migration test. This discovers whether the link partner using STP
still exists, and if so whether it has migrated to RSTP or MSTP. If it still exists as an
STP link, the device continues to communicate with it by using STP. Otherwise, if it
has been migrated to RSTP or MSTP, the device communicates with it using RSTP
or MSTP, respectively.
