Spanning Tree Commands Set

Command

Level

Description

Example

spanning-tree enable

Enable spanning tree

switch(config)#

spanning-tree enable

spanning-tree priority

[0~61440]

Configure spanning tree

priority parameter

switch(config)#

spanning-tree priority

32767

spanning-tree max-age

[seconds]

Use the spanning-tree

max-age global

configuration command

to change the interval

between messages the

spanning tree receives

from the root switch. If a

switch does not receive

a bridge protocol data

unit (BPDU) message

from the root switch

within this interval, it

recomputed the

Spanning Tree Protocol

(STP) topology.

switch(config)#

spanning-tree

max-age 15

spanning-tree

hello-time

[seconds]

Use the spanning-tree

hello-time global

configuration command

to specify the interval

between hello bridge

protocol data units

(BPDUs).

switch(config)#

spanning-tree

hello-time 3

spanning-tree

forward-time

[seconds]

Use the spanning-tree

forward-time global

configuration command

to set the

forwarding-time for the

specified spanning-tree

instances. The

forwarding time

determines how long

switch(config)#

spanning-tree

forward-time 20
