Enabling one or more STP debugging modes for a period of time displays
information for STP troubleshooting (Table 18) to the port on which the switch
received the command, or to the console.
To enable, disable or show the debug modes, use the commands:
ENABLE STP DEBUG={MSG|PKT|STATE|ALL} PORT={port-list|ALL}
[OUTPUT=CONSOLE] [TIMEOUT={1..4000000000|NONE}]
DISABLE STP DEBUG={MSG|PKT|STATE|ALL} PORT={port-list|ALL}
SHOW STP DEBUG
Set OUTPUT to CONSOLE if using this command in a script. Each of the
debug modes can be enabled or disabled independently. Use the TIMEOUT
parameter to prevent the switch or display from being overloaded with
debugging data.
