1.10 STP Maintenance Configuration
1.10.1 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.
