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.
Syntax
debug mstp {all|cli|protocol [detail]|timer [detail]}
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
the
terminal monitor
command before issuing the relevant
debug mstp
