debug mstp (RSTP and STP)

Overview Use this command to enable debugging for the configured spanning tree mode,
and echo data to the console, at various levels. Note that although this command
uses the keyword mstp it displays debugging output for RSTP and STP protocols
as well the MSTP protocol.
Use the no variant of this command to disable spanning tree debugging.
debug mstp {all|cli|protocol [detail]|timer [detail]}
Syntax
debug mstp {packet {rx|tx} [decode] [interface <interface>]}
debug mstp {topology-change [interface <interface>]}
no debug mstp {all|cli|protocol [detail]|timer [detail]}
no debug mstp {packet {rx|tx} [decode] [interface <interface>]}
no debug mstp {topology-change [interface <interface>]}
Mode Privileged Exec and Global Configuration mode
Usage 1 Use the debug mstp topology-change interface command to generate
debugging messages when the device receives an indication of a topology change
in a BPDU from another device. The debugging can be activated on a per-port
basis. Although this command uses the keyword mstp, it displays debugging
output for RSTP and STP protocols as well as the MSTP protocol.
Due to the likely volume of output, these debug messages are best viewed using
