Description

Example

spanning-tree enable

G

Enable spanning tree

switch(config)#spanning-tree enable

spanning-tree priority 

[0~61440]

G

Configure spanning tree
priority parameter

switch(config)#spanning-tree priority
32768

spanning-tree max-age 

[seconds]

G

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]

G

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]

G

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 

each of the listening and 

learning states last before 
the port begins forwarding.

switch(config)#spanning-tree forward-time
20

stp-path-cost 

[1~200000000] 

I

Use the spanning-tree cost 

interface configuration
command to set the path 
cost for Spanning Tree

Protocol (STP) calculations. 
In the event of a loop, 
spanning tree considers the 
path cost when selecting 

an interface to place into 
the forwarding state.

switch(config)#interface fastEthernet 2
switch(config-if)#stp-path-cost 20
