debug spanning-tree

Enables debugging for the Spanning Tree Protocol.

Synopsis

debug spanning-tree {all | bpdu {rx | tx {all | interface port-channel number | tengigabitethernet 
slot/port} } 

no debug spanning-tree {all | bpdu {rx | tx {all | interface port-channel number | 
tengigabitethernet slot/port} } 

Operands

all    

Turns on spanning tree packet debugging on all interfaces.

bpdu

Turns on Bridge Protocol Data Unit debugging.

rx

Turns on debugging for only received spanning-tree packets.

tx

Turns on debugging for only transmitted spanning-tree packets.

interface port-channel number

Specifies the port-channel interface. The range of valid values is 1-63.

interface tengigabitethernet

Specifies the 10 Gbps Ethernet interface.

Specifies the slot number.

Specifies the port number.

Defaults

By default debugging is not turned on.

Command

Modes

Privileged EXEC mode

Description

Use this command to enable debugging for the Spanning Tree Protocol. Use the no debug 
command to disable debugging.

Usage

Guidelines

To display debugging outputs on a particular cmsh session, use the terminal monitor command.

Examples

To enable debugging of spanning-tree for both Rx and Tx on 10 Gbps Ethernet interface 0/1:

switch#debug spanning-tree bpdu rx interface tengigabitethernet 0/1

switch#debug spanning-tree bpdu tx interface tengigabitethernet 0/1

switch#show debug spanning-tree

MSTP debugging status:

  Spanning-tree rx debugging is off

    Te 0/1 rx is on

  Spanning-tree tx debugging is off

    Te 0/1 tx is on
