Note. When changing the protocol to MSTP or from MSTP, the bridge priority and port path cost values
for the flat mode CIST instance are reset to their default values. However, if the path cost mode was set to
32-bit prior to the protocol change, the path cost is not reset to its default value. See the
mode command page for more information.
