MSTP Maintenance Configuration
Introduction
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.
