enable mstp debug
Syntax ENAble MSTp DEBug={Msg|Pkt|State|All} MSTI={CIST|instance|
ALL} [POrt={port-list|ALL}] [Statemachine={PTM|PRX|PPM|
PIM|PTX|PRS|PRT|PST|TCM|ALL}] [Output=Console]

where:
■ instance is the instance number of the selected MSTI in a range from 1 to
4094.
■ port-list is a port number, range (specified as n-m), or comma-separated list
of port numbers and/or ranges. Port numbers start at 1 and end at m,
where m is the highest numbered Ethernet switch port, including uplink
ports.
Description This command enables MSTP debugging for either a specified MSTP instance
or all instances, or on specific port or ports.
The msti parameter specifies the spanning tree instance that will have its
debugging mode enabled. If cist is specified, then debugging will be enabled
on the CIST. If an MST instance is specified, then debugging will be enabled on
the msti specified. If ports are specified using the port parameter, then the
debug will be enabled on the specified port on the specified instance. If all is
specified and the ports are specified using the port parameter, then the
debugging mode for the listed ports will be enabled on all the instances with
the listed ports.
The instance number is for the specified msti.
The debug parameter specifies which debugging modes are to be enabled. If
all is specified, then all debugging modes for the instances or ports will be
enabled. The other modes can be enabled independently of each other.
The debugging modes enabled by each option are shown in Table 1 STP
debugging options.
Setting the output parameter to console instructs the bridge to send the
debugging information to the console. By default, the debugging data will be
sent to the port that received the enable mstp debug command. This option
should be selected if the enable mstp debug command is used in a script,
because a script is not received on a port.
