The rapid transition feature can be enabled on only root ports or alternate
■
ports.
If you configure the rapid transition feature on a designated port, the feature
■
does not take effect on the port.
In a large-scale network with MSTP enabled, there may be many MSTP instances,
and so the status of a port may change frequently. In this case, maintenance
personnel may expect that log/trap information is output to the log host when
particular ports fail, so that they can check the status changes of those ports
through alarm information.
