Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
Specify a point-to-point link if the interface can only be connected to
exactly one other bridge, or a shared link if it can be connected to two
or more bridges.
When automatic detection is selected, the switch derives the link type
from the duplex mode. A full-duplex interface is considered a
point-to-point link, while a half-duplex interface is assumed to be on
a shared link.
RSTP only works on point-to-point links between two bridges. If you
designate a port as a shared link, RSTP is forbidden.
Example
spanning-tree protocol-migration
This command re-checks the appropriate BPDU format to send on the
selected interface.
