Follow the steps below to change the forwarding time. 

Step  Command 

Description 

Step 1  configure terminal 

Enters the configuration mode 

Step 2  To configure the max age time: 

spanning-tree forward-time<time-value> 

Configures the switch spanning tree 

max age time. 

 

time-value – Spanning tree forward 

time may be from 4 to 30 seconds. 

 

The default forwarding time is 15 

seconds. 

Step 3  end  

Exits the configuration mode. 

Step 4  show spanning-tree bridge forward-time 

 

Displays the spanning tree forward 

time. 

Step 5  write startup-config 

Optional step – saves this spanning tree 

configuration to be part of startup 

configuration. 

 

 

The “no spanning-tree forward-time” command resets the spanning tree forwarding time to 

the default value of 15. 

 

The example below shows how to configure the spanning tree forward time. 

Configure the forwarding time as 12 seconds. 

SMIS# configure terminal 

SMIS(config)# spanning-tree forward-time 12 

SMIS(config)# end 

6.15

 

Max Hops 

MSTP uses a hop count to decide the validity of BPDU messages. The root switch sends a BPDU with a 

max hops count. Every switch decrements the hops count when forwarding the BPDU. When this hops 

count reaches zero, the switch discards the BPDU message. 

The default max hops count is 20.  

Follow the steps below to change the max hops. 

Step  Command 

Description 

Step 1  configure terminal 

Enters the configuration mode 

Step 2  To configure the max age time: 

Configures the switch MSTP max hops
