Basic idea of analyzing the faults: First check the link and then confirm the
protocol configuration.
First analyze the physical reason, including whether the device works
normally and whether the cables are normal;
Checking method: Use the ping packets to view the flashing status of the
ACT light; test whether the data is forwarded via Forwarding after passing
the MSTP network; use the show spanning-tree mst detail command
on the device to view whether the bridge and port status are correct.
