This example shows how to set the MST interface so that it always sends MSTP messages in the prestandard
format:
switch# config t
switch (config)# interface ethernet 1/4
switch(config-if)# spanning-tree mst pre-standard
switch(config-if)# exit
switch(config)#

Specifying the Link Type for MST - CLI Version

Rapid connectivity (802.1w standard) is established only on point-to-point links. By default, the link type is
controlled from the duplex mode of the interface. A full-duplex port is considered to have a point-to-point
connection; a half-duplex port is considered to have a shared connection.
